Key Takeaways:

• The CO2 was collected using direct air capture technology. 
• The carbon won’t return to the atmosphere, even if the concrete is demolished. 
• The team believes that CO2 storage in concrete could be a major asset to achieve climate goals.

The Whole Story:

Carbon dioxide (CO2) captured via direct air capture (DAC) has been permanently stored in concrete for the first time in a demonstration project led by CarbonCure Technologies and Heirloom.

The team announced that Heirloom captured CO2 from the atmosphere using their DAC technology at their headquarters in Brisbane, California. Technology developed by Nova Scotia-based CarbonCure was used to to inject the captured CO2 into the process wastewater at a Central Concrete batch plant in San Jose, California. Central Concrete used the CO2-treated wastewater to make fresh concrete, which was produced for a range of construction projects across the Bay Area. 

Stored forever 

The team explained that the CO2 is sequestered in the concrete as calcium carbonate, and will not be returned to the atmosphere, even if the concrete is demolished. 

Heirloom runs America’s only operational DAC facility. It uses limestone, an abundant, easy-to-source and inexpensive material, to pull CO2 from the air. 

The team explained that this is done by harnessing a cyclic process. The limestone is broken down into calcium oxide rock and CO2 gas using heat from a renewable-energy powered, electric kiln. The calcium oxide is spread onto vertically stacked trays where it acts like a sponge – pulling CO2 from the air before it is returned to the kiln and the process begins again. The captured CO2 gas is then permanently stored safely underground or embedded in concrete.

Using Canadian technology 

CarbonCure Technologies licenses a suite of carbon mineralization solutions for hundreds of concrete plants globally. CarbonCure’s reclaimed water technology was used to store Heirloom’s CO2 at Central Concrete. The technology injects CO2 into reclaimed water (recycled water collected from washing out concrete trucks) at concrete plants. When injected, the CO2 immediately reacts with cement in the water and mineralizes, permanently storing the CO2 and stabilizing the cement for reuse. The CO2-treated slurry is then used in new concrete mixes.

Central Concrete was the first concrete supplier in the Bay Area to adopt CarbonCure’s technologies for ready-mixed concrete. 

“This demonstration project is a global milestone for carbon removal technology that confirms concrete’s enormous potential as a climate solution that can permanently store carbon in our most essential infrastructure – from roads and runways to hospitals and housing,” said Robert Niven, chair and CEO of CarbonCure Technologies. “We’re thrilled to be collaborating with Heirloom and Central Concrete on this groundbreaking world first.”

“The science is clear: In order to reach climate goals we must remove billions of tons of already emitted CO2 from the atmosphere each year,” said Shashank Samala, CEO of Heirloom. “This is an important step toward that future and shows the promise of DAC technologies combined with smart, permanent methods of sequestration.”

Looking to a zero-carbon future

The team stated that the application of a DAC-to-concrete solution is a significant step forward in permanent atmospheric CO2 removal. 

“As the world moves toward zero-carbon energy generation, DAC technologies will play a key role in remediating past emissions, and helping to decarbonize industries as they develop and scale carbon-cutting solutions,” they said. 

They noted that even the most aggressive emissions reduction projections from the UN Intergovernmental Panel on Climate Change will require the removal of 6-10 billion tons of CO2 per year by 2050 to stick to a 1.5 C warming pathway. 

“DAC technologies are some of the most promising methods of carbon dioxide removal, and have recently received large investments from the U.S. government through the Department of Energy’s $3.5 billion DAC hub program and the Inflation Reduction Act,” they said. 

The added that the world’s most-utilized building material, concrete provides an important repository for permanent CO2 storage. With the global building stock expected to double by 2060 – the equivalent of building another New York City every month – concrete presents a key opportunity to store immense quantities of carbon dioxide in our built environment.

Improving the performance of our buildings is a major part of combatting climate change.

According to the World Economic Forum, buildings are responsible for about 40 per cent of global energy consumption and about one-third of global greenhouse gas emissions.

This has led many to pursue Passive House, a method of design and construction that can create buildings that consume up to 90 percent less heating and cooling energy than conventional work. According to Passive House Canada, it is the only internationally recognized, proven, science-based energy standard in construction.

The history of Passive House in Canada goes all the way back to the 1970s, with the Saskatchewan Conservation House in Regina. The visionary project had no furnace but still performed three times better than traditional builds at the time. According to the University of Regina, it was one of the first conservation demonstration houses constructed in North America.

Since then, Passive House buildings in Canada have got far more ambitious and more high-tech. We went through Passive House Canada‘s database to highlight some of the many projects under construction or recently completed across the country.

This one is for the outdoor adventurers. Located near the hiking paradise of Squamish, the design includes south facing windows to soak up low winter sun, while rolling cedar blinds can be adjusted for solar gains in the summer. According to the international Passive House database, the windows on the north side are placed minimally, allowing for cross-ventilation and natural light. The west facade features an oversized lift and slide patio door. This gives the covered deck area a seamless extension of the open-concept kitchen and living space. WHM Structural Engineers is handling the engineering and MIZU Passive House Consulting is the Passive House consultant.

Azilda PH – Sudbury, Ontario

This single-family home is being constructed with slab on grade with insulated concrete form walls using a Legalett Thermal Wall system. The second floor will use Hambro steel floor joist with 4″ concrete topping and typical roof trusses. The design situates the house due south with for forest views. For heating, the home will use two energy recovery ventilators for each unit and heat pumps.

Lakewood – Vancouver, B.C.

This project is a collection of 24 townhomes and is one of two Passive House communities being developed by Dimex Group in Vancouver’s Grandview-Woodland neighbourhood. Dimex says the energy-efficient homes aim to reduce heating costs by $15,000 over 10 years with triple glazed windows, 7 inches of increased airtight insulation and Passive Home heat recovery systems.

Naikoon Contracting, the project’s developer and contractor, says the home is positioned in the single-family RS-5 zone over on the West Side of Vancouver. It combines the thermal performance of Passive House with stylish, minimalist design. The design includes two primary dwelling units and flexible lock-off suites. The project team includes One SEED Architecture + Interiors.

Blind Bay PHilo – Carling, Ontario

According to the project’s architect, Passive House 43 Architecture, this generational home aims to preserve and promote the pristine setting of Georgian Bay. The design features framed views to draw attention to the shoreline while a strategic material palette allows the building to blend with the exposed Canadian Shield and dense forest. In addition to Passive House, the building is targeting off-the-grid capabilities. The project team also includes Interactive Construction and Blackwell Engineers.

Pontoon Cove Eco House – Victoria, B.C.

ONE SEED Architecture + Interiors. They wrote that Pontoon Cove Eco House is a modern home perched above the ocean on a rocky point on Vancouver Island. The design embraces sustainability holistically, including environmentally and healthy materials in and out, as well as a photovoltaic array on the roof which should result in net zero operating energy demand. They are are using Passive House certified fiberglass windows manufactured in B.C., as well as a certified front door and huge wood sliders manufactured on Vancouver Island. The home is built above a crawl space, so the design was able to avoid rigid insulation within the primary envelope of the house all-together.

Norra Hem – Lac Supérieur, Quebec

This home’s builder, Constructions PSB, explained that the design was constrained by the specificities of the land so the team opted for an inverted floor plan: bedrooms on the ground floor and living space on the first floor. Large openings are strategically placed to ensure maximum daylight and solar gains despite the complexity of the terrain. The house is mainly heated by radiant heat on the two floors according to dedicated zones, and is equipped with a powerful centralized ventilation system.

Koshoshiki – Squamish-Lillooet Regional District, B.C.

It’s another one from the team at ONE SEED Architecture. They explained that the name “Kōshōshiki no ie” in Japanese roughly translates to “stilt house” which is apt for this design. The minimalist home is built on a series of posts that give it great views and minimize its impact on the environment. It means less concrete and rigid foam insulation. Creating a structural steel grid on which to sit the house, allowed for floors, as well as the walls, and roof to be prefabricated off-site. This minimized the need for equipment on site and disruption to the surrounding ecosystem.

Neu on 3rd – North Vancouver, B.C.

Who doesn’t love a cool cross section shot? Neu on 3rd includes five buildings with a total of 27 Passive House townhouses. The project features homes with garages, private front doors, and rooftop patios. Each individual home has their own Zehnder HRV system, Passive House rated windows and doors, and double exterior wall construction. The challenge is to incorporate district hot water to the homes and meet Passive house certification. The project team includes architect Marken Design and contractor Levu Development. Western Development is the owner.

Bau-Biologie House – Port Stanley, Ontario

According to Passive House Canada, this project is a design-build ultra-performing home that addresses building biology concerns for the naturopath owners and their family.

The contractor on the project is Interactive Construction.

Affinity House – Wasaga Beach, Ontario

Koko and Robert Saar began researching Passive House design and construction in 2016 and eventually decided to build their own by forming their own company, CedarValley Passive Homes. The couple says they faced challenges including delays in window deliveries from Poland, budget overruns, trades needing continuous onsite supervision, birds and cement pouring at -10 C.

Pacific Passive House – Cobble Hill, B.C.

Want to feel motivated and inspired? Consider the story of this project. Lucas Tubman, owner of Limitless Carpentry, built this project with no experience in Passive House design or construction. The house is situated on a three-acre lot oriented due south with a gentle slope making it perfect for a walk-out basement. It has wide open views of Baldy Mountain and plenty of trees for shade and privacy. The lot was originally full of fir and cedar trees. In order to take advantage of the southern exposure and solar gain, the team had to clear half of the lot. The trees were milled, producing 50,000 board feet which is being used as timber framing, siding, flooring, soffit and some ship lap feature walls. The team noted that the main challenge was learning insulating concrete forms. They didn’t adequately stage all 20 tons of rebar which added time and cost to the project as they had to sort through and handle the steel.

Meadowbrook Place – Windsor, Ontario

Meadowbrook Place is a new 145-unit development and Ontario’s largest Passive House. It will provide a mix of market-rate, affordable and subsidized units. The building provides unit sizes that are in the highest demand: bachelor, one-bedroom and three- bedroom units. The architect is Kearns Mancini Architects Inc.

WHA Passive House Employee Apartments – Whistler, B.C. 

Integra Architecture worked with the Whistler Housing Authority (WHA) on an employee housing project committed to environmentally sensitive practices. They expected it would be the first multi-family building with Passive House certification in Whistler. The development is located in the Cheakamus Legacy Area. The building consists of 20 rental units that WHA will be able to maintain at a lower cost meaning low rent for local employees. Finding affordable housing for workers that serve the popular tourist area has long been a major issue.

LV Residence Passive House – Vancouver, B.C.

Designed and built by VictorEric Premium Homes, this custom single-family house is situated on a southeast corner site in the Westside of Vancouver. Atop a basement level and two storeys, the roof deck captures views of the Northshore mountains.

Baker House – Gibsons, B.C.

According to Passive House Canada, this single-family home is a collaboration with and for Linda Baker Architect by CX Contracting. The team stated that they were looking for new efficiencies in super-insulated building technique, and so they extended the capabilities of a panel system that CX has been developing for the past six years. They decided to pre-clad the the structural wall panels. Inspired by the Brock Commons building at UBC, the team thought it could be possible to push the boundaries in residential construction and move to an exterior finished system, controlling many of the airtightness issues, in shop conditions. Passive House Canada records noted that the team faced challenges with adhesives, substrates, cladding and temperature/moisture changes, but they are now confident that these issues have been resolved to produce a robust system.

Gerri Carroll Hope Centre – Regina, Saskatchewan

Passive House buildings aren’t just for the rich and famous. They can also help the community’s most vulnerable residents. In 2018, the Gerri Carroll Hope Centre was officially opened. The new 17-unit affordable rental housing development serves individuals who have complex needs and are unable to secure and maintain housing without supports. It was a momentous task the first involved cleaning up a site contaminated with lead and acid.

Ripple House – Gibsons, B.C.

Little details could be found on this project except that the uniquely designed wood-forward project was delivered. The drawing above will have to tell the story. That sure is one heck of a roof.

Blossom Park – Woodstock, Ontario

According to Natural Resources Canada, construction of the Blossom Park multi-unit residential complex was completed in 2020. The building follows the Passive House approach of high levels of insulation and a focus on air sealing the building envelope. For the walls, Christian charity Indwell used the Build SMART prefabricated wall panel system, built offsite in a controlled factory setting and delivered to be assembled at the building site. Passive House-certified triple-pane windows and insulated, thermally-broken doors were selected to complete the envelope. To ensure airtightness, a quality assurance program was put in place, including training for sub-contractors and periodic inspections of envelope detailing. The project was designed by Invizij Architects

Pretty River Passive House – Collingwood, Ontario

This project entailed constructing a 2500-sq-ft,  two-storey contemporary home attached to an existing cedar shingle log house and a new garage via breezeways in the Collingwood area north of Toronto. According to Passive House Canada, the team sought to use conventional framing methods with advanced insulation products to comply with Passive House criteria. The project was designed by William Dewson Architect Inc.

The Heights – Vancouver, B.C.

This 85-unit apartment complex, designed by Cornerstone Architecture, is one of the largest Passive House projects in the country. According to the Pembina Institute, this building uses 35 cm-thick, double R40 walls with a 2×6 external insulated wall, a two inch layer of polystyrene insulation and an inside insulated 2×4 wall where all the plumbing and wiring goes. A continuous layer of polystyrene insulation protects the building from the outside world and all fresh air comes through a heat recovery system that is 85 per cent efficient. Each unit is heated by small electric resistance heaters that use about one third of the energy of a single hair dryer.

This is a big one. Clayton Community Centre is North America’s first Passive House certified community centre, and the largest non-residential certified project in Canada. The building combines arts and culture programming including music studios, recording studios and a community rehearsal hall, with recreational activities including a gymnasium and fitness centre, and a branch library. It was designed by HCMA Architecture + Design Business. EllisDon completed the project in 2022.

Alberta St. Passive House – New Westminster, B.C.

This is another mysterious Passive House with little information. All that we know is it was built by Lanefab, an integrated design/build company that crafts custom homes and laneway houses. Their approach to construction and design has been covered by the New York Times, Forbes and TEDx.

Atlantic Coast Passive House – Indian Harbour, Nova Scotia

Finally some Nova Scotia in the mix. This project is a modern style bungalow with a walkout basement located on oceanfront property in Indian Harbour. Passive House techniques allow to be heated with minimal mechanical equipment, including a single mini-split ductless heat pump. According to Sawlor Built Homes, the project’s contractor, the home features a “Butterfly Metal Roof” system that collects rain water from both buildings and stores it in an underground cistern. The cistern is equipped with a water treatment system which then treats the rain water and supplies the house with fresh water. A photovoltaic system on the roof uses cells to convert sunlight into electricity. According to the project’s blog, after one year it achieved a 4,275 kWh energy surplus.

It offers a 99.67 per cent reduction in operational carbon emissions compared to the existing Fire Hall 17. It is also one of 16 projects to pilot the Canada Green Building Council’s new ZCB standard.

Key Takeaways:

• SNC-Lavalin is partnering with Ontario Power Generation to build Canada’s first grid-scale small modular reactor. 
• The project will be built using an alliance contracting model that includes Aecon and GE-Hitachi.
• Officials say projects like this are critical for reaching Ontario’s zero-emission power goals. 
• It will be Canada’s first new nuclear reactor in 30 years. 

The Whole Story:

Candu Energy Inc. a member of the SNC-Lavalin Group has entered into an agreement with Ontario Power Generation (OPG) to deliver the Darlington New Nuclear Project.

The project is spearheading the deployment of the GEH BWRX-300 Small Modular Reactor (SMR) before the end of the decade. It will be the first grid-scale SMR deployed in Canada.

“SNC-Lavalin is a strong proponent for the necessary role of nuclear power in the Net Zero energy mix,” said Ian L. Edwards, president and CEO, SNC-Lavalin. “As we’ve laid out in our Engineering Net Zero report, Canada’s 2050 Net Zero commitments will require large-scale electrification of transportation, buildings and heavy industrial processes. That electricity needs to be generated from clean, reliable, and cost-efficient sources, whose employment in the energy mix will not weaken energy security. Our involvement in what will be Canada’s first SMR to come to market, and its first nuclear new build in roughly 30 years, reaffirms SNC-Lavalin’s leading position in the nuclear energy market, for both existing and new nuclear technologies.”

The project will be delivered using a six-year alliance agreement approach. SNC-Lavalin said this in itself is an innovation for a nuclear project in North America. As part of an alliance with Aecon and GE-Hitachi, SNC-Lavalin will provide OPG with a diverse range of expertise for the engineering and build of the Darlington Nuclear Generating Station’s SMR. This is expected to include deploying project management, licensing, engineering, design, procurement, construction support and commissioning, as well as digital delivery capabilities in both the nuclear island and balance of plant scopes for the project.

“Following our on-time, on-budget success working with OPG on the refurbishment of Darlington’s existing CANDU reactors, we are very pleased to contribute our expertise with our alliance partners on this exciting new build,” said Joe St. Julian, president, nuclear, SNC-Lavalin. “Canada was the second country in the world to ever generate commercial nuclear power. Together with our alliance partners, we will ensure Canada again leads the way to advance an exciting new frontier in nuclear energy. We continue to work with SMR vendors in Canada and around the world to bring more of these reactors online, coinciding with a rise in interest from jurisdictions looking to use nuclear power to decarbonize their energy mix, while maintaining their energy self-sufficiency.”

SNC-Lavalin says it plans to leverage its Canadian Nuclear Safety Commission licensing expertise and experience as a reactor developer. As the original equipment manufacturer of CANDU reactors, SNC-Lavalin is the only company to have a technology pass all three phases of the Canadian Nuclear Safety Commission’s pre-project design review, and will leverage its extensive nuclear new build expertise to drive a successful outcome for this first of a kind project.

“SMRs will play a key role in helping to reinvigorate Ontario’s economy and further support the province and Canada as we work toward meeting our climate change targets of zero-emission electricity,” said Ken Hartwick, president and CEO of OPG. “Canada’s ability to lead in global SMR deployment is enabled by our strong nuclear supply chain, as evidenced by the on time, on budget delivery of the existing Darlington Refurbishment Project. Building on our relationship as part of that refurbishment, we are pleased to welcome SNC-Lavalin and its expertise to the team that is deploying the BWRX-300 as the first SMR to be commissioned in North America.”

Canadian Solar Inc. announced that a wholly-owned subsidiary of its majority-owned subsidiary CSI Solar Co., Ltd. has entered into a multi-year investment agreement with the municipal government of Yangzhou City in Jiangsu Province, China. Under the Agreement, CSI Solar plans to add vertically integrated high efficiency wafer, cell, and module capacity, as well as battery system manufacturing capacity, in Yangzhou’s clean energy manufacturing industrial park.

The project plan will be carried out in three phases, with phase I being 14 GW of wafer and cell capacity. 

Phase I is expected to commence production in the second half of 2023, while the implementation of phase II and III is subject to change, at the company’s discretion, based on market conditions and the company’s assessments.  With this announcement and considering the solar supply chain‘s demand and supply backdrop, the Canadian Solar updated its 2023 year-end capacities to 20 GW of ingot, 35 GW of wafer, and 50 GW of cell and modules.

Canadian Solar was founded in 2001 in Canada and is one of the world’s largest solar technology and renewable energy companies. It is a leading manufacturer of solar photovoltaic modules, provider of solar energy and battery storage solutions, and developer of utility-scale solar power and battery storage projects with a geographically diversified pipeline in various stages of development. 

Key Takeaways:

• The machine will increase the supply and availability of soil erosion control blankets for Western Canada and parts of the U.S.
• BMP Supplies is setting up the machine in an Alberta warehouse with ample supply to hay.
• The machine is set to be up and running sometime next month.

The Whole Story:

A million dollar machine in an Alberta warehouse is poised to upend a commonly overlooked corner of Canada’s construction sector. 

Paul Lindemulder, who works in sales and marketing for his family business, BMP Supplies, explained that his father started the company 20 years ago with one of its most popular products, a catch basin protector. The orange, donut-shaped devices prevent unwanted sediment from going into catch basins. He soon began creating other devices, like turbidity curtains that prevent runoff into bodies of water like lakes.

But one sought after product remained elusive for decades: soil erosion control blankets. 

“That was always the dream,” said Lindemulder. “In this industry it’s kind of the big product that is most common because it is used in so many applications. It does a lot more than other products. It’s a dream product to release for a company like ours.”

The blanket is a fabric roll made with jute or plastic netting filled with straw or coconut to protect soil from wind and water erosion. It is typically used to protect slopes and embankments and can help to reduce runoff and help promote the growth of vegetation.

The process to get the product is complex and expensive. You need three things – an expensive and rare machine that weaves the blankets, a large warehouse to store it and a nearby supply of high-quality hay. Only one other machine exists in Canada and it’s far from many parts of Western Canada. This causes long lead times for orders and high shipping costs. Lindemulder said this has caused many projects in the west that would have liked to use erosion control blankets to forgo them.

BMP is primarily based out of Calgary with two warehouses. Its head administrative office is in Surrey, B.C. As leadership of the company started to transfer over to Jim’s four sons, the company decided it was time for a major play. 

First they secured a 12,000 square-foot building on a five acre site in Brooks, Alta. close to a nearly endless supply of straw. Then they ordered the machine that weaves the blankets. It’s made in Germany by AH Meyer and costs roughly $1 million. The 80-foot long and 20-foot wide machine recently arrived in seven boxes and a team of experts from Europe will help assemble it in Brooks.  

“It’s a game changer,” said Lindemulder, who noted that the Brooks location sets BMP up to supply projects in western North America. “It’s something everyone wants in their jobs but getting it is difficult. That motivated us to get it in the hands of construction companies. It’s great for the environment as it protects sensitive areas and now sites can be specced for this product.” 

Lindemulder anticipates erosion blanket product could begin as early as next month.

“We are getting the word out and letting customers know,” said Lindemulder. “It’s about getting the whole industry to change focus, especially in Western Canada.”

Victoria, B.C. is stepping up its underground infrastructure.

Crews have started work on water main upgrades on Blanshard Street in what is the second year of a decade-long $53.8 million renewal of critical underground infrastructure. The project, which is receiving support from the Government of Canada’s Disaster Mitigation and Adaptation Fund (DMAF), stretches between Caledonia Avenue through to Fort Street and will continue through summer 2023. 

“Reliable water and wastewater treatment systems protect communities and the environment,” said Dominic LeBlanc, minister of intergovernmental affairs, infrastructure and communities. “We will continue to work collaboratively with local governments to build resilient communities, in British Columbia and across Canada.” 

Victoria Mayor Marianne Alto noted that resilient cities have resilient underground systems. “Renewing and upgrading our underground infrastructure is critical to protect our communities and ensure our core water, sewer and stormwater services can be maintained in the event of an earthquake or a climate change event,” said Alto.

In addition to the water main work on Blanshard Street, other large city projects this year include upgrading the Chatham Street Sewer Pump Station, replacing sanitary sewers on a portion of Cook Street and the rehabilitation of a sanitary sewer on Store Street. 

“Strengthening and renewing our underground infrastructure is not only key to protecting the high quality water, sewer and stormwater services everyone relies on every day, it is vital to ensuring the health and resiliency of Victoria for years to come,” said Philip Bellefontaine, director of engineering and public works. “Major projects such as these will minimize future infrastructure costs, serve our growing community and help keep us safe during climate and seismic events.” 

Officials noted that these projects are in addition to the four already completed in 2021 and 2022 to replace or upgrade aging infrastructure, some more than 100 years old, to support growing neighbourhoods. Over the next decade, the city plans to invest nearly $54 million in 78 capital infrastructure projects, a 40 per cent increase in capital infrastructure investments compared to the past 10 years. 

To minimize disruption and maximize public benefit, the City is coordinating the Blanshard Street water main works with other improvements which will include new road paving, replacement of old traffic signal equipment and new road markings to make it safer for pedestrians and cyclists and easier for traffic to circulate in the downtown. Staff are working with the contractor to minimize traffic impacts where possible, however the public should plan for travel delays resulting from this construction. 

Key Takeaways:

• The University of Toronto is putting researchers and construction industry leaders together to come up with innovative solutions for sustainable infrastructure.
• The team plans to address issues well beyond the traditional bounds of engineering, including explore legal frameworks around housing rights.
• The school believes that by including the industry in the process, the insights gained through their research can more easily be applied.

The Whole Story:

The newest research centre at the University of Toronto’s Faculty of Applied Science & Engineering will develop innovative ways to meet the urgent and growing need for infrastructure – without further exacerbating the climate crisis.

The Centre for the Sustainable Built Environment brings together seven researchers from across U of T, as well as a dozen companies in construction and related industries. 

The research collaboration includes Colliers, the Cement Association of Canada, Chandos Construction, Mattamy Homes, Northcrest, Pomerleau, Purpose Building Inc., ZGF Architects, Arup, SvN Architects + Planners, Entuitive and KPMB Architects.

The goal is to identify strategies that will lower the environmental footprint by reimagining how new infrastructure is designed, where it is built and what materials are used in its construction.

“In Canada and around the world, we have a huge housing and infrastructure deficit – there’s a big social need to build much more than we have right now,” said Shoshanna Saxe, associate professor in the department of civil and mineral engineering and Canada Research Chair in Sustainable Infrastructure.

“At the same time, construction resource use accounts for up to a third of total global greenhouse gas emissions each year, a problem that is getting worse. It’s been estimated that if we continue current ways of construction, by 2050 the emissions due to new housing alone will cause us to blow past two degrees of global warming,” she adds. “If we want to avoid that, let alone reach net zero by 2050, we need to find ways to do more with less.”

Saxe and her collaborators – Evan Bentz, Chris Essert, Elias Khalil, Heather MacLean, Daman Panesar and Daniel Posen, all fellow U of T researchers – plan to approach the complex challenge from several different angles. They believe some efficiencies can be found by looking at where new housing is built, as well as what it looks like.

“The average person living in a city consumes fewer resources than the average person living in a suburb, because in a city you have more people per kilometre of sewer, road or electrical infrastructure. There are big rewards for well-designed cities,” Saxe said. “The shape and types of buildings we build is also important. For example, Toronto has a lot of long skinny apartments, where a lot of the space is in the hallway. If we design differently, we can better use that space to provide more housing, or avoid [extra space] all together and save materials, emissions and cost.”

Saxe and her team have also shown that large concrete basements account for a high proportion of the emissions due to construction – building more of the structure above ground could improve the environmental bottom line. Other potential solutions involve alternative building materials, such as new types of concrete that are less carbon-intensive.

The multidisciplinary team – whose researchers cover a wide range of expertise, from carrying out life-cycle analysis of construction projects to defining national carbon budgets – will address issues well beyond the traditional bounds of engineering. For example, the group plans to explore the legal frameworks that translate established housing rights into practical built spaces.

“It’s absurd to say that the right to housing means that everyone has to live in a space the size of a closet,” Saxe said. “But it’s also absurd to expect everyone to have their own 3,500-square-foot house. Can we find a middle ground where everyone can live in dignity, without consuming in a way that threatens the planet?”

By working closely with a core group of construction leaders, Saxe and her collaborators aim to speed up knowledge translation, ensuring that the insights gained through their research can be applied in industry.

“The conversations we have with our partners can inform their design and construction, as well as the conversations they then have with their clients, raising everyone’s level of knowledge and awareness,” she says.

“We hope that by giving people – policymakers, designers and builders – the tools they need to address these challenges of building more with fewer emissions, we can improve outcomes across the built environment and create a more sustainable future for everyone.”

Key Takeaways:

• $7.1 million is being spent on helping 12 First Nations communities in B.C. shift to greener energy.
• The projects include solar farms, biomass heat-and-power systems, and more.
• The funding stems from the province’s Community Energy Diesel Reduction (CEDR) program

The Whole Story:

Twelve First Nations communities throughout British Columbia will receive $7.1 million to develop alternative-energy projects and advance energy efficiency through the province’s Community Energy Diesel Reduction (CEDR) program, a CleanBC initiative.

“Our CleanBC goal is to reduce diesel consumption for power generation in remote communities by 80 per cent by 2030,” said Josie Osborne, minister of energy, mines and low carbon innovation. “By building partnerships and creating opportunities with Indigenous communities and businesses, we can help people living in B.C.’s hardest-to-reach communities save money, become less dependent on fossil fuels and benefit from cleaner air and water.”

The energy projects range in size and scope, from $350,000 for the construction of a biomass combined heat-and-power system for the Lhoozk’uz Dene Nation (Quesnel area), to $2 million to develop and build a two-megawatt solar farm on Haida Gwaii’s northern grid that will include battery storage.

The $29-million, three-year CEDR program aims to reduce remote communities’ reliance on diesel fuel, and to support projects focused on energy efficiency and/or those that provide clean, reliable energy year round in areas not serviced by grid electricity. CEDR is part of the Province’s Remote Community Energy Strategy.

British Columbia has 44 remote communities, most of which are governed by First Nations. Many of these communities are served by BC Hydro in non-grid integrated areas. Some First Nations own and operate their own diesel generators. In 2019, the remote communities consumed at least 19.1 million litres of diesel, emitting the equivalent of 51,784 tonnes of carbon dioxide.

The CEDR program provides funding for clean-energy initiatives to eligible remote communities that are off-grid residential regions that rely on diesel fuel for electricity generation. Remote communities can apply to three funding streams to support them as they progress through various stages of their planning and implementation of their decarbonization projects. Officials say this will help to ensure remote communities have financial supports throughout the life cycle of their energy projects, whether it be at the beginning, early, mid or late stages of planning, or implementation of their decarbonization projects.

To deliver the CEDR program, the province has partnered with the New Relationship Trust to facilitate investments with remote communities for community energy planning, energy-efficiency projects, and renewable-energy infrastructure. In addition, Coast Funds is working with the trust to support applications from First Nations with communities in the Great Bear Rainforest and Haida Gwaii that rely on diesel to meet their electricity needs.

A second round of CEDR program funding will be announced shortly, and applicants are encouraged to connect with the New Relationship Trust and Coast Funds for more details and assistance. Coast Funds and the trust work with all eligible First Nations and remote communities to develop strong proposals that maximize access to CEDR program funding.

“Making the switch from diesel fuel to renewable energy to heat your home or power your lights can be a challenge, especially if you live in a remote or isolated community,” said George Heyman, minister of environment and climate change strategy. “This funding will help First Nations make the shift to cleaner energy alternatives, which will reduce emissions and create economic opportunities in their communities.”

Key Takeaways:

• Top CEOs from real estate and other industries pledge to reduce buildings-related emissions by at least 50 per cent by 2030 and be fully net-zero carbon no later than 2050.
• Real estate is one of the biggest sources of global GHG but is often overlooked in wider decarbonization strategies.
• CEOs will also implement the World Economic Forum’s Green Building Principles and Action Plan to make progress on their emissions targets.

The Whole Story:

A group of CEOs is pledging to reduce their real estate emissions by 50 per cent by 2030 and reach net-zero carbon no later than 2050.

In a press release, the CEOs stated that buildings contribute 38 per cent of all energy-related greenhouse gas emissions, meaning leaders across all industries have a critical role to play in lowering their global real estate emissions.

“While real estate represents nearly 40 per cent of all energy-related GHG emissions, the sector is frequently an afterthought when it comes to an organization’s decarbonization and sustainability strategies,” said Matthew Blake, head of financial and monetary systems for the World Economic Forum. “Leaders across all industries have a responsibility to take action on their real estate GHG emissions to ensure progress in the fight against climate change.”

The following companies have pledged to halve their buildings-related emissions by 2030 and reach net-zero building emissions by 2050: Avison Young, Edge, GPFI Group, Ivanhoé Cambridge, JLL, Majid Al Futtaim Properties, Schneider Electric and Signify.

The firms noted that they will meet these targets by implementing the forum’s Green Buildings Principles. Released last year, the Green Building Principles: The Action Plan for Net-Zero Carbon Buildings offers this sequence of steps to deliver net-zero carbon real estate portfolios:

1. Calculate a robust carbon footprint of your portfolio in the most recent representative year to inform targets

2. Set a target year for achieving net-zero carbon, by 2050 at the latest, and an interim target for reducing at least 50 per cent of these emissions by 2030.

3. Measure and record embodied carbon of new developments and major refurbishments.

4. Maximize emissions reductions for all new developments and major refurbishments in the pipeline to ensure delivery of net-zero carbon (operational and embodied) by selected final target year.

5. Drive energy optimization across both existing assets and new developments.

6. Maximize supply of on-site renewable energy.

7. Ensure 100% off-site energy is procured from renewable-backed sources, where available.

8. Engage with stakeholders with whom you have influence in your value chain to reduce scope 3 emissions.

9. Compensate for any residual emissions by purchasing high-quality carbon offsets.

10. Engage with stakeholders to identify joint endeavours and equitably share costs and benefits of interventions.

Developed in collaboration with JLL, the World Green Building Council and the Forum’s Real Estate community, the Green Building Principles can be formally adopted by firms and include an Action Plan detailing implementation.

The Action Plan provides globally applicable guidance on best practices to implement the principles for every stakeholder, from owners to occupiers to investors. Signatories will report progress annually as part of their public sustainability reporting and participate in a Practitioners Group to identify solutions around implementation.

“The emphasis on bringing together the world’s leading businesses and public figures to collectively address issues like climate change and driving social change is fundamental to what Avison Young stands for. ESG considerations across the board must be addressed by the real estate sector — buildings have a huge impact on our everyday lives and the planet,” said Mark E. Rose, chairman and CEO of Toronto-based Avison Young. “We are thrilled to adopt the Green Building Principles and demonstrate to our peers that reaching net zero is not only possible but essential for a better built environment and more resilient and successful cities.”

Key Takeaways:

• The project began development in 2017.
• In includes roughly 1.3 million solar panels.
• It’s expected to generate electricity in Alberta for more than 35 years.

The Whole Story:

The largest solar project in Canadian history has reached substantial completion. 

The project team – which includes PCL Construction, Greengate and Copenhagen Infrastructure Partners – announced this month that the Travers Solar Project is substantially completed. 

The Alberta project first began development in 2017 and includes approximately 3,330 acres of land located eight kilometres southwest of the Village of Lomond, in Vulcan County. The project is located on privately owned, cultivated and grazing land. It includes approximately 1.3 million solar panels

According to project officials, the site has a strong solar resource, which is characteristic of Alberta’s resource, and the project will generate clean energy over its 35+ year lifetime.

The project is 465 megawatts (MW) in size. Work involved installing solar PV modules, power conversion stations, an electrical collection system, access roads and the construction of the Little Bow Project Substation to connect to the Alberta Interconnected Electric System. 

When work began, the project team expected a total capital cost of approximately $700 million. It’s expected to generate enough power for more than 150,000 homes.

Key Takeaways:

• The plant will cease producing general use cement in favour of OneCem, a reduced carbon portland limestone cement.
• It’s Lafarge’s third plant conversion this year.
• Lafarge says OneCem creates 10 per cent less C02 emissions while maintaining performance and durability.

The Whole Story:

Lafarge Canada is continuing its march towards greener cement production. 

The company announced it has fully transformed its Brookfield Cement Plant’s cement production in Nova Scotia to a greener portfolio. From now on, the site’s production of general use cement (GU) ends and will shift to reduced carbon portland limestone cement – branded as OneCem – the company’s eco-efficient alternative. 

Brookfield is Lafarge’s third cement plant to be converted in 2022 and the first Atlantic Market plant to convert – the others being the Bath Cement Plant (Ontario) in June and the Richmond Cement Plant (B.C.) earlier this year.

OneCem is a sustainable product that presents up to 10 per cent lower CO2 emissions while providing the same performance and durability. 

“We have been steadily moving the needle forward when it comes to cement decarbonization and we will continue to honour our commitment in progressing our greener portfolio in Eastern Canada over the coming years,” said Andrew Stewart, vice president of cement for Lafarge Canada (East). “For us at Lafarge Canada, sustainability and profitability go together – our main goal is to keep partnering with our customers to advance sustainable construction and, at the same time, provide innovative world-class products.”

According to Robert Cumming, Head of Sustainability & Public Affairs, Lafarge Canada (East), the company has avoided more than 140,000 tonnes of CO2 in the past four years by converting GU cement to OneCem in its plants across Canada.

“We are excited to take our plant to the next level of decarbonization. Our teams on the ground have been successfully showcasing our company’s values of passion, collaboration, and grit, and we couldn’t be prouder. This is a very important milestone in our Net-Zero journey in Nova Scotia and in Canada as a whole,” said Travis Smith, Brookfield’s plant manager.

Larfage officials explained that OneCem contributes to lowering the industry’s carbon footprint not only during the manufacturing process – while cement may be as little as 11 per cent of a concrete mix, it can account for more than 80 per cent of all energy required to produce concrete. Across Canada, Lafarge has produced over 6 million metric tonnes of OneCem since 2011.

ACCIONA Canada took to the skies to celebrate 20 years of sustainable infrastructure construction in Canada. 

The company partnered with reforestation startup Flash Forest to plant 20,000 trees in B.C. using drones.

Planting from above

By leveraging drone, AI, GIS, and plant science technology, Flash Forest planted Douglas-fir, Hybrid Spruce, Western Larch and Lodgepole Pine in natural disaster-affected areas of the province.

“Having a direct positive impact on the environment we are building within is part and parcel with our Sustainability Master Plan 2025 (SMP 2025),” said Caroline Miwa, director of quality, health and safety, environmental and sustainability for ACCIONA North America. “ACCIONA is building some of B.C.’s largest transportation and clean energy projects, and so the project with Flash Forest in B.C. was intentional and meaningful.” 

ACCIONA has published a five-year SMP since 2010, and it continues its roadmap for every business action worldwide.

“Our sustainability strategy has evolved and strengthened with each edition of the SMP,” said Miwa. “The 2015 edition was focused on measuring key performance Indicators, 2020 aimed to integrate and engage all stakeholders to align our sustainability approach, and 2025 goes a step further to not only minimize our footprint, but to make a positive impact.”

Miwa noted that “Planet Positive” is one of the four pillars underpinning SMP 2025 and supporting the regeneration of impacted forests in B.C. contributes to its global organizational goal of planting and monitoring the growth of one million trees within five years.

She also reflected on the ACCIONA’S long history of infrastructure. 

20 years building Canadian infrastructure

“ACCIONA Infrastructure entered the Canadian market 20 years ago with one of the country’s most iconic hydraulic projects to-date, the Deep Lake Water Cooling System in Toronto,” she said. “The system draws cold water from the bed of Lake Ontario and uses it to cool downtown Toronto office towers – a sustainable alternative to conventional air cooling. The system is still in use today.”

Miwa said that since the start of the 2000s, ACCIONA has continued to deliver sustainable infrastructure solutions that have a positive impact on the community and environment, from the Saint John Safe Clean Drinking Water Project in New Brunswick which supplies 75 million liters of safe drinking water to the community every day, to the award-winning Royal Jubilee Hospital Patient Care Centre in Victoria, B.C., to the Broadway Subway Project currently under construction in Vancouver that will take cars off the road and reduce greenhouse gas emissions.

More than building projects

She added that ACCIONA’s sustainability efforts aren’t just limited to projects. 

“It is important to remember that sustainability also encompasses community engagement,” said Miwa. “The ACCIONA joint venture delivering the Site C Clean Energy Project in Fort St. John, B.C. founded a Community Investment Program in 2016 that has since donated $375,000 to the North Peace Community Foundation in support of local charities. What’s more, 100 per cent of the donation was generated by our onsite recycling program.”

Miwa added that for ACCIONA, sustainability also means diversity, equity and inclusion (DE&I).

“‘People Centric’ is another pillar of our SMP 2025, under which ACCIONA aims to increase the percentage of women in middle and senior management positions every year – across all business lines globally,” she said. “In Canada, we are continuously improving the percentage of women in these positions and are proud that women make up almost 30 per cent of the North America leadership team.”

She added that safe, clean water has also been a major focus of ACCIONA’s efforts. 

On one of its major transportation projects in B.C., tunnel water treatment plants are operated onsite to treat water resulting from tunnelling activities. Treated water is then discharged into sanitary sewage according to the specifications of the city of Vancouver.

Assisted by technology

Advances in technology are helping ACCIONA’s work on the “People Centric” pillar of the SMP 2025 by creating safer job sites and decreasing harmful emissions. They are using drones on site to assist with survey works, which eliminates hazards that our team might otherwise be exposed to. The company is working to electrify its fleet and is even investigating the use of hydro-treated vegetable oil bio-fuel across its operations.

Miwa explained that sustainability should be a concern for everyone in the industry. 

“It is well known that the construction industry is a large contributor to greenhouse gas emissions,” she said. “As contractors, we are in a unique position to educate and influence sustainable decision-making both upstream to clients and peak bodies, and downstream to the supply chain. The industry – at every level – needs to move faster to execute infrastructure that will help restore social and environmental balance and regenerate the planet.”

Key Takeaways:

• Researchers in Toronto will test the viability of various methods of trapping CO2 in concrete.
• It is a collaboration between University of Toronto and the Canada Green Building Council.
• Officials say the collaboration will make it easier for research findings to get translated into industry, as well as into new policies and regulations.

The Whole Story:

Where do you put carbon once you capture it? 

Researchers in Toronto are investigating the potential of burying it into one of the world’s most common products: concrete. 

The work is a collaboration between a team of researchers led by Daman Panesar, a professor in the University of Toronto’s department of civil and mineral engineering in the Faculty of Applied Science & Engineering, and the Canada Green Building Council (CAGBC). The team will identify the potential and implications of low-carbon approaches and technologies and how they might capture large amounts of CO2 and trap it in concrete.

The project is funded by a $1.7 million contribution by the Government of Canada.

“Currently, several low-carbon concrete framework documents have been produced worldwide and most of these roadmaps have set 2050 carbon reduction targets related to several levers, such as clinker-cement ratio, alternative fuel use and carbon capture, storage and sequestration,” said Panesar.

The researchers noted that while there has been preliminary work on several carbon utilization approaches, few have been implemented on a large scale. Panesar and her team will examine the challenges associated with scale-up of these strategies and explore new technologies that can effectively turn built infrastructure into a carbon sink.

“Natural carbonation of concrete occurs by a chemical reaction between the constituents of concrete, particularly cement, and atmospheric carbon dioxide – and it has the potential to occur throughout the life of the concrete,” said Panesar. “However, accelerated or enforced carbonation approaches are relatively new technologies, which can also be referred to as carbon capture and utilization technologies, and can be introduced at different life stages such as during manufacture or at end-of-life.”

Some examples of processes that will be explored and assessed include: 

• CO2 injection
• Elevated CO2 exposure
• Mineral carbonation using recycled or waste CO2
• Industry by-products used to replace cement and subsequent CO2 curing
• Synthetic treated aggregates

“All of these techniques need further understanding of the implications and potential for negative emission technologies such as carbon capture utilization approaches,” Panesar says.

The researchers explained that another challenge for both new and existing structures is ensuring that any change to the formulations of concrete – for example, using lower-carbon components or absorbing more CO2 during curing – doesn’t come at the expense of its required structural and material design properties, including strength and durability.

“For example, considering natural carbonation processes, the mechanism related to the potential for increased vulnerability of reinforced concrete elements to steel corrosion, concrete degradation and shortened service lives is fairly well understood.” said Panesar.

“For existing infrastructure, the situation becomes more complex because there is a need to account for and interpret the role of age-related cracking on the CO2 uptake of concrete, as well as in conjunction with other predominant degradation issues in Canada, such as freeze-thaw cycles.”

Finally, researchers stressed that there is a need to develop benchmarks and other standardized tools to accurately account for the carbon uptake in building materials.

“Currently, there is no harmonized measure of concrete carbonation and the differences in measurements and reporting add an extra dimension of complexity when trying to compare between different concrete formulations and/or CO2 uptake technologies,” said Panesar.

“Carbon accounting is critical to enable us to determine the relative environmental impacts of the various approaches and to be able to estimate or forecast the impacts of deploying these new technologies in the coming decades.”

Officials noted that one major benefit of the research collaboration is that it provides a built-in pathway for new research findings to get translated into industry, as well as into new policies and regulations.

“As the national organization representing members and stakeholders across the green building spectrum, CAGBC can access industry expertise to help advance research and mobilize the sector to implement market solutions,” says Thomas Mueller, president and CEO of the Canada Green Building Council.

Key Takeaways:

• PCL Solar will be responsible for estimating, design, performance analytics, solar-specific technology, project execution and in-house commissioning.
• The operation will be led by Andrew Moles.
• The solar team’s new work attainment was $1.1 billion in 2021 alone.

The Whole Story:

PCL Construction’s solar business is rising. 

The company announced the formation of PCL Solar, which is based in Toronto with satellite offices in strategic centers across the United States and Australia. They believe it will deliver an even wider array of renewable energy projects as demand increases.

“The demand for high-performing solar facilities will only increase in the coming years as the world transitions away from carbon-producing forms of energy generation,” said Andrew Moles, general manager of solar for PCL Construction. “PCL has risen to the challenge by assembling an outstanding renewable energy team ready to meet the needs of this ever-growing market.” 

In five years, PCL’s solar team has completed a number of large projects, including Travers Solar, which will be the largest solar project in Canada, the Gunnedah Solar project in New South Wales, Australia, and U.S. projects in Texas, Oregon, Georgia, Colorado, Tennessee and beyond. The solar team’s new work attainment was $1.1 billion in 2021 alone.

PCL said it anticipates significant opportunities for continued growth in 2023 and beyond. 

Andrew Moles will lead the Solar operation as general manager. Andrew began his career at PCL in 2007 and started working on solar projects in 2009. Since then, he has led solar expansion efforts across North America and Australia. He has served as a board member on the Canadian Solar Industries Association and as a board member and Vice-Chair of the Utility-Scale Solar Division of the US Solar Energy Industries Association. He is recognized by the Canadian Construction Association as a Gold Seal Certified Project Manager and is a LEED accredited professional.

The operation will be responsible for estimating, design, performance analytics, solar-specific technology, project execution and in-house commissioning.

Key Takeaways:

• The company will access the vehicle’s performance in Squamish, B.C.
• It is part of GFL’s goal to reduce greenhouse gas emissions in its fleet.
• The company has already switched 15 per cent of its fleet over to cleaner fuels.

The Whole Story

GFL Environmental, a North American environmental services company, has introduced its first first fully electric automated side loader (ASL) truck, in B.C.

The vehicle has already been on a long journey. Its chassis was built at Mack Trucks in Pennsylvania; its body was mounted at Labrie Automizer in Quebec; and from there it attended Waste Expo in Las Vegas. Now, the truck has moved to its new permanent home in Squamish.

The company explained that Squamish is a perfect place for GFL to introduce an electric truck. The district of Squamish declared a climate emergency in 2019 and is actively working towards creating a low-carbon future. Decarbonizing transportation is one strategy being adopted to reduce emissions.

“Environmentalism is appreciated in the natural beauty of Squamish and the District of Squamish has been quite vocal on electrical adoption,” said Tyler Stefure, GFL’s fleet director for Western Canada. “They have expressed interest in seeing what a private hauler can do. I think this truck will get a lot of attention for us in Squamish.”

The new truck operates with a near-silent powertrain, providing quiet service to the residents on its route. The truck produces no exhaust emissions and requires no oil changes. It will be charged overnight so it’s ready to tackle its route the next day.

Denise Imbeau, general manager of GFL’s Squamish facility, added that the area is a huge draw for outdoor enthusiasts, including skiers, mountain climbers, mountain bikers and windsurfers.

“Our community is very eco-minded, innovative and forward thinking,” Imbeau said. “Investment in electric technology aligns with the values of this community and demonstrates the commitment GFL has to our community and our planet.”

GFL stated that one of its key sustainability objectives is to continue to reduce GHG emissions from operations and increase the use of alternative and low-carbon fuels in its fleet. The company has already switched 15 per cent its collection fleet over to compressed natural gas (CNG) fuel.

“The electric truck is intended to do everything that its gas and diesel counterparts can do,” Stefure said. “Obviously, battery life is influential so as time goes on, we’ll really put it through its paces and see how it does.”

GFL’s plan is to first learn how to safely operate and care for the truck, then to test it in a variety of situations to figure out what limitations, if any, need to be considered.

“There’s a lot of speculation on what the truck should do. The proof is in what it can do, and that’s why BC is such a great proving ground for us,” Stefure said. “It offers different climates and different terrains, so we can run the truck in Squamish and maybe run it in the Lower Mainland or someplace really cold, just to find out how it performs.”

Canada has announced its first National Adaptation Strategy which establishes a common direction for preparing for climate change events.

“Canadians in every region of the country are already feeling the effects of climate change, and the costs of these impacts are projected to rise to $25 billion by 2025 and to the range of $100 billion annually by 2050,” said Jonathan Wilkinson, minister of natural resources. “Inaction is not an option. Through the National Adaptation Strategy, we will advance key resilience and adaptation measures to mitigate these changes, preserve livelihoods and protect our communities and the critical infrastructure we depend on. The result will be a stronger, safer and more prosperous place to call home.”

The strategy focuses on five key systems:

• Disaster resilience
• Health and well-being 
• Nature and biodiversity 
• Infrastructure 
• Economy and workers.

Officials noted that climate change is warming southern Canada at twice the global average and approximately three times as quickly in the North.

The strategy was announced this month by Bill Blair, president of the King’s Privy Council for Canada and minister of emergency preparedness. Blair also unveiled the Government of Canada Adaptation Action Plan, which sets out the federal role in preparing Canadians for climate hazards and outlines specific investments, programs and initiatives that are making Canada more resilient to climate impacts. Blair announced over $1.6 billion in new federal spending to support climate adaptation.

If action isn’t taken, it’s going to cost Canadians. The Canadian Climate Institute estimates that by 2025 Canada will experience annual losses of $25 billion as a result of climate change. This is equal to 50 per cent of projected 2025 Gross Domestic Product (GDP) growth.

Resilient Infrastructure

Some of the infrastructure-related actions being taken in the plan include:

• Delivering the national Disaster Mitigation and Adaptation Fund to mitigate current and future climate-related disasters and the Natural Infrastructure Fund to support nature-based climate solutions.  
• Investing in climate-resilient infrastructure by topping up the Disaster Mitigation and Adaptation Fund by up to $489 million over 10 years.
•  Spending up to $60 million over five years to accelerate the use of climate-informed codes, standards and guidelines for resilient infrastructure in Canada.  
• Investing up to $95 million over five years to deliver climate toolkits and services that increase the uptake of climate resilient practices and investments in communities.

The strategy is now open to the provinces, territories and National Indigenous Organizations for a final 90 days of engagement on the strategy’s common goals and specific measurable targets and objectives. Officials said that the strategy is a result of extensive engagement since 2021 and presents a shared vision for climate resilience in the country and a framework to measure progress nationally.

Investing now to save later

Making adaptation investments now will have major economy-wide benefits later. Federal officials noted that expert research suggests that every dollar invested in prevention and preparation can save up to 15 dollars in costs. 

Researchers found that implementing new flooding and wildfire guidelines and standards for new construction could save Canada an estimated $4.7 billion a year — saving nearly $12 per $1 invested. They also discovered that climate-resilient building codes implemented in Canada have an estimated benefit–cost ratio of 12:1 — equivalent to a 1,100 percent return on investment.

Key Takeaways:

• Collaboration between government and industry will be key to hitting targets.
• Huge progress can be made right now without waiting for future technological advancements.
• An action plan is expected to be released in the coming months.

The Whole Story:

The most-used construction material on the planet is on a mission to decarbonize and Canada wants to do its part. 

This fall the Cement Association of Canada took its first major step after years of coordination and planning with the federal government and industry stakeholders by releasing the Roadmap to Net-Zero Carbon Concrete by 2050.

The document provides guidance on the technologies, tools and policies needed for the Canadian cement industry to achieve net-zero carbon emissions while ensuring it remains competitive in a global net zero economy.

It can’t be done alone

The roadmap was spearheaded by a joint government-industry working group, co-led by the Cement Association of Canada and Innovation, Science and Economic Development Canada. The working group includes key players from the federal government, the Canadian cement and concrete industry, and relevant environmental experts.

The team effort was indicative of what will be needed in the coming decades to achieve the net-zero goal. 

“One of the common themes of the roadmap and really any part of our journey is it’s something we can’t do alone,” said Adam Auer, president and CEO of the Cement Association of Canada. “There’s no possibility to achieve this without the collaboration of government and different folks in the construction value chain and ultimately technology providers.”  

He noted that the industry has been working on decarbonization since the 1990s and that Canada’s effort is just one piece of an entire global effort. Last year, dozens of members of the Global Cement and Concrete Association announced their roadmap to achieve net-zero emissions by 2050.

According to the Canadian roadmap, decarbonization pathways for the cement industry include low carbon fuels, performance-based codes, standards and procurement policies, material efficiency, and carbon capture (CCUS). With approximately 60 percent of cement emissions resulting from industrial processes in the manufacturing of clinker (the key ingredient in cement), clean technologies like CCUS are needed for the industry to meet net-zero emissions.

Government key to early work

Auer noted that while the decades-long effort will involve many different stakeholders, much of the early work lies with the government. 

“Things are starting to change with progressive developers but all three levels of government in Canada purchase about 40 per cent of the concrete the country uses. They have an opportunity to be a market maker for innovation and it’s a big focus of our work,” said Auer. 

The association believes the government and its various agencies could help incentivize and streamline innovation. 

The association is currently working with François-Philippe Champagne, minister of innovation, to foster innovation through procurement, derisk low-carbon ideas and find the pinch points that are hindering decarbonization. 

A good example of this was the Department of Finance’s Fall Economic Statement which helped close the gap with the Inflation Reduction Act thereby ensuring Canada remains a first choice for the trillions in private capital waiting to be invested in clean technologies around the world. The association believes the financial incentives and tools put forward in the FES will help Canada’s industrial sectors thrive in a competitive global green economy.

Auer noted that the collaborative attitude from government and industry bodes well for the net-zero goal. 

“It’s very encouraging. This has been a bit of a missing ingredient up till now. I think a lot of folks in the construction sector are starting to look at the challenge and opportunity of embracing an industrial decarbonization agenda for concrete,” said Auer. “Some fantastic people are coming to the table to learn about how we can do this. It’s extremely encouraging and i think the industry as a whole finds it encouraging. That collaborative spirit is something we’ve been trying to foster for many years.”

But it’s not going to be easy. Auer explained that going forward, ambition and momentum need to be maintained among the many different groups. 

“The challenge is there are a lot of moving pieces,” he said. “There are lots of players even within the government. There is no single government department with all the tools to unlock decarbonization.” 

These departments include the National Research Council, Standards Council, Environment and Climate Change Canada, Natural Resources Canada, Treasury Board of Canada Secretariat and many others. 

“There’s a huge number of institutions that have their own structures that have to coalesce around this agenda. That’s a hard thing to do. Government is a largue bureaucracy and there is a lot if siloing that needs to be broken down.”

There is no silver bullet to save us

Auer explained that instead of a silver bullet, it will take a load of buckshot to achieve decarbonization goals. CCUS gets a lot of buzz and with 60 per cent of concrete emissions coming from how it’s manufactured, Auer said reaching net-zero simply cannot be done without it. There’s even a large-scale carbon capture project underway in Edmonton that could make it the world’s first carbon neutral concrete plant. 

But Auer says that while these advances are exciting, there is no reason to wait. The industry can get 60 per cent of the way to net zero without CCUS. This includes using greener fuels to heat kilns, extracting value from waste products, optimizing mixes and designing infrastructure with only the amount of concrete necessary. 

“If you want to hit targets you have to take advantage of stuff we can do immediately: optimizing existing technology and being more efficient in how we design infrastructure,” said Auer. 

The next step will be completing an action plan for the net-zero goal, which Auer said is expected in the coming months. The plan will include significant milestones, including cutting carbon emissions up to 40 per cent by 2030.

“Canada could be a leader in this space,” said Auer. “The trick will be making moves that are matching the ambition of similar efforts in the U.S. and other jurisdiction. Cement producers are all multi-national and competing for internal capital as well. We want to make sure Canada is the most attractive region for our companies to invest in.”

The Business Development Bank of Canada (BDC), a Crown corporation and national development bank, announced its new $400 million Climate Tech Fund II which has the goal of creating world-class Canadian cleantech champions. The new envelope brings the fund’s committed investments in the innovative cleantech and climate tech sector to $1 billion.

BDC launched its Cleantech Practice’s $600 million Fund I in 2018 to address the lack of risk capital for the commercialization and scale up of Canada’s cleantech and climate tech industry. BDC stated that the fund was innovative in that it was flexible, multistage, and patient, which better suited the entrepreneurs in the space.

“BDC will play a leading role in helping Canadian climate tech firms dream bigger and become global technology champions,” said Isabelle Hudon, BDC’s president and CEO. “Here at home, BDC will enable the scale up and deployment of low carbon technologies which are so fundamental to Canada’s ability to meet its GHG emissions reduction targets. This new Climate Tech Fund reflects BDC’s ambition to help build a clean, low carbon, circular economy.”

BDC’s Cleantech Practice partners with leading global institutional investors and government funding programs to support dozens of high potential cleantech and climate tech firms. Now that Fund I is fully committed, BDC’s new Climate Tech Fund II will help preserve and extend Canada’s position in the strategic sector by continuing to build and grow the ecosystem for climate tech firms.

“BDC’s Cleantech Practice is one of the largest, most active investors of its kind in Canada. Our investment strategy is not about market trends but GHG emissions reduction,” said Jérôme Nycz, executive vice president, BDC Capital. “BDC’s Climate Tech Fund II will reinforce the importance of low carbon supply chains, help the commercialization, scaling and adoption of Canadian technologies in Canada and abroad and create opportunities for climate tech firms.”

The bank noted that Canada currently ranks second on the Global Cleantech Innovation Index compared to seventh in 2014 but believes more progress can be made. Bank officials explained that the global cleantech market is expected to double in value, reaching more than $400 billion US by 2026. BDC says it will continue to support longer development timeframes and larger capital needs typical of many climate tech ventures. The nank expects Fund II to be fully committed over the next five years.

“With Climate Tech Fund II, we will continue to invest along the full lifecycle of leading-edge, disruptive Canadian firms to support their growth and the deployment of technologies critical for our country to reach net zero,” says Susan Rohac, managing partner, climate tech fund, BDC Capital. “Canada is fortunate to have an increasingly robust and well-coordinated network of Crown Corporations, agencies, departments, and private sector partners supporting climate tech entrepreneurs. Our team will continue to do its part to reinforce this ecosystem to accelerate Canada’s innovation outcomes in climate technologies.”

The Cleantech Practice currently has a portfolio of 50 companies, including firms that have been recognized as Global Cleantech 100 Companies. 

Key Takeaways:

• The Stack, a 37-storey office tower, is officially a Zero Carbon Building.
• Oxford achieved this through low carbon building systems, triple-pane glazing on all windows, rainwater management and enhanced air tightness and other methods.
• Oxford says it wants to share its lessons from the project and encourage others in the industry to set high sustainability goals.

The Whole Story:

The Stack, a downtown Vancouver office tower, is making history. 

The project’s developer, Oxford Properties Group, announced that The Stack, has achieved the Canada Green Building Council’s Zero Carbon Building – Design standard certification. The 37-storey, 550,000 sq. ft. commercial office tower is Canada’s first commercial high-rise office tower to achieve this certification.

As well as being the first high-rise commercial office tower to achieve the certification, it is also the largest project in Canada to achieve it to date. Upon completion later this year, The Stack is set to become the tallest office building in Vancouver.

The project team includes Ledcor and it was designed by James K.M. Cheng Architects.

Size created bigger challenges

Oxford noted that the project’s size added to the technical complexities required to achieve the Zero Carbon Standard. The project team stated that they incorporated many innovative features that minimize carbon emissions, energy and water usage as well as landfill waste. These include low carbon building systems, triple-pane glazing on all windows, rainwater management and enhanced air tightness. On-site renewable energy will be achieved through the use of a rooftop photovoltaic solar panel array.

“Oxford’s purpose is to create economic and social value through real estate and The Stack embodies Oxford’s ongoing commitment to sustainability and decarbonization,” said Andrew O’Neil, vice president of development for Oxford. “The CaGBC certification is the culmination of over five years of planning to pioneer a new zero carbon framework in a high-rise and architecturally-significant office tower, all while juggling the demands of realizing an economically-viable commercial project for our stakeholders.”

O’Neil added that the lessons learned from the project can now be applied to future projects, and shared with industry peers.

Oxford isn’t stopping there. The team is also targeting LEED v4 Platinum Core and Shell certification. Oxford plans to deploy smart building technology to provide insights on energy management, optimize building performance and enable preventative maintenance. The Stack will feature 250 bike parking stalls and club-quality fitness and change facilities for an exceptional customer experience. Oxford says this is meant to encourage wellness and promote sustainability. 

Reducing total carbon footprint 

The Stack is one part of a larger direction the company has been moving in. In 2015, Oxford set out to reduce its carbon footprint by 30 percent by 2025. Last year Oxford announced it had exceeded their goal, reducing its portfolio carbon intensity by 37 percent, four years ahead of schedule. Company officials explained that this was made possible by pioneering groundbreaking new developments that raise the bar on sustainability, investing in data and analytics to set hourly carbon targets for its properties and human solutions that encourage sustainable active transportation.

“Oxford continues to demonstrate leadership in lowering carbon emissions across their portfolio. The Stack is the first new high-rise office building to achieve CAGBC’s Zero Carbon Building – Design certification. With this stand out project, Oxford is setting a new benchmark for Canada’s top real estate owners,” said Thomas Mueller, president and CEO, Canada Green Building Council. “Shifting investor and market interests in carbon solutions, along with advances in technology and know-how, make it more feasible for Canada’s major real estate projects to follow suit. 

Sustainability is good for business 

The company noted that The Stack is set to become the latest in a line of landmark developments. These include Vancouver’s MNP Tower, 402 Dunsmuir and Riverbend Business Park, Manhattan’s St. John’s Terminal which was recently acquired by Google, The Leadenhall Building in London and Toronto’s Park Hyatt. The Stack is currently 70 per cent pre-leased.

“Oxford has strong conviction that best-in-class offices that are smart, wellness-focused and sustainable will continue to be highly desirable to occupiers and continue to outperform,” said Ted Mildon, senior director at Oxford. “There is a real need among businesses to ensure they are located in buildings that not only inspire and engage their workforce, but also actively contribute to their own ESG goals. As a result of our Zero Carbon certification, The Stack is uniquely positioned to do so in the Vancouver market.”
