TOWARD CIRCULARITY IN THE BUILT ENVIRONMENT (CBE)

By Vince Catalli

In collaboration with Circular Construction Canada (CCC), Canadian Standards Association (CSA Group) is driving an initiative to help transition Canada’s construction sector from a linear “take-make-dispose” model to a circular, net-zero, and low-carbon economy. This initiative focuses on developing standards and a strategic framework to promote the reuse of materials, adaptive design, and the extension of building lifespans to reduce life cycle environmental impacts.

Nature as Inspiration

Nature is the perfect design process operating as a balanced net-zero, closed-loop system where there are no wasted resources. A balanced net zero closed-loop system is an integrated, sustainable model that eliminates waste and reduces greenhouse gas (GHG) emissions by continuously cycling resources and energy within a self-sustaining system, balancing any necessary inputs with equivalent removals.

Canada generates approximately 4 million tonnes of construction, renovation, and demolition (CRD) waste annually (approximately 1.8 million tonnes of embodied carbon), accounting for roughly 12% of the country's total solid waste. While estimates vary, this represents a significant portion of landfill content, with only about 16% to 20% currently diverted through recycling or reuse.1

At the same time, in 2025, a year’s worth of biological resources were used in just 6.7 months, in other words, the equivalent of 1.8 Earths’ worth of resources would be needed for the entire year of 2025. 2 This will only get worse as developing countries’ economies progress. It is clear that our linear system of “take, make, waste” is increasingly destructive and unsustainable, with potentially catastrophic consequences. 

The Circular Built Environment (CBE) approach combines circular economy principles (closed-loop resource use for extended lifespans) with net-zero targets (reducing input loads, offsetting emissions, and relying on renewable methods) to create a restorative rather than destructive impact on the natural and built environment.

Used together, “balanced” emphasizes the equilibrium (inputs=outputs), while “net zero” focuses specifically on carbon (emissions=removals). In essence, a “Balanced Net Zero Closed Loop” pathway refers to a strategic, holistic, and cost-effective approach to circularity (eliminating waste), based on modified approaches and systemic changes.

A Paradigm Shift

CBE represents a paradigm shift for our industry, responding to global advances within the Circular Economy space. At its core, CBE strives to “eliminate waste” using balanced net-zero closed-loop approaches to managing resource inputs to the built environment. These inputs include material resources, energy, and water. As an example, the following life cycle animates the circularity of material resources and the shift that is being proposed. (Diagram 1).

INTERVIEW WITH: Stephen Boudreau of Teritt Indoor Environmental on Green Building Indoor Air Quality Testing

DO GREEN BUILDING PRACTICES RESULT IN BUILDINGS WITH BETTER INDOOR AIR THAN TRADITIONAL BUILDINGS?

Yes. Overall, the selection of better performing building materials and products has a positive impact on the air quality of the finished building. Based on indoor air quality investigations we’ve been involved in over the years, we consistently find better indoor air quality in green buildings.

WHAT ARE SOME OF THE FACTORS IN THE DESIGN AND CONSTRUCTION PROCESS THAT PRODUCE A BUILDING WITH GOOD INDOOR AIR QUALITY?

Ventilation design, building materials selection, proper protection and storage of building materials prior to installation, and proper sequencing of materials installation. Also, a tight building envelope and moisture-resistant construction helps to prevent mold growth and uncontrolled pollutant entry. These things are all generally well planned for on green building projects.

WHEN IT COMES TO GREEN BUILDING CERTIFICATION SYSTEMS, WHAT’S THE MOST IMPORTANT FACTOR TO HELP ENSURE THAT THE IAQ TESTING ACHIEVES A PASS?

This is hard to distill down when reflecting on the 450+ green building projects we’ve tested over the years, as dozens of factors can influence IAQ testing success. I would have to say the number one factor that causes green building projects to fail the IAQ testing is too much activity on site leading up to and on the testing date.

Generally, the allowable levels for airborne contaminants from the rating systems for LEED, Green Globes, WELL, etc. are in the parts per million or parts per billion range. These are very low levels to achieve and as a result, there are dozens of seemingly benign site activities that can have an impact on the testing results. In an ideal scenario, there is nobody on site on the testing date other than the IAQ testing agent, but this is often not achievable and requires the use of other mitigating strategies.

IN RATING SYSTEMS WHERE BOTH OPTIONS ARE AVAILABLE, IS AIR QUALITY TESTING OR BUILDING FLUSH OUT A BETTER ROUTE?

The ideal scenario is some amount of building flushout followed by an IAQ test to verify airborne contaminant levels. Verification in most processes is an important step, and it is no different with IAQ. If you have time in the schedule, flush the building and then perform some level of testing to verify that the IAQ is good. If you don’t have time for a building flush, test the air and plan for some level of post occupancy flushout to keep off-gassing contaminant concentrations to a minimum.

WHAT HAS BEEN THE MOST REWARDING PART OF WORKING AS AN IAQ CONSULTANT IN THE GREEN BUILDING SECTOR?

The people. 100% the people. Over the last 16 years we have worked with team members from a wide range of backgrounds and professions. The vast array of personality types in the green building sector has made the work fun, challenging, and entertaining all at the same time. Never a dull moment. Also, architecture and design have always been an area of great interest to me on a personal level, so getting a close-up look at hundreds of amazing new buildings over the years has been a nice bonus.

Can $10 per square foot result in 40% carbon savings?

The Purpose Retrofit Accelerator’s initial insights in cost transparency and real-world case studies turn ambitions into action

Deep retrofit momentum is growing across Canada, with more building owners, managers and investors moving from early planning to implementation – and initial success stories show deep retrofits can deliver better value. But financing barriers, and lack of clarity around cost and return on investment, and a fragmented policy landscape remain top barriers to achieving retrofits at scale.

These findings are reflected in a market sounding report from the Canada Green Building Council (CAGBC) and Purpose Building: “Accelerating Deep Retrofits – A Year of Insights on Progress and Barriers.” It shares insights about current attitudes and emerging trends on building retrofits across Canada, drawing from participants in The Purpose Retrofit Accelerator.

Launched in April 2024 by Purpose Building in partnership with CAGBC, the Accelerator is supported with funding from Natural Resources Canada. The program helps owners and managers of large buildings plan, finance, and implement energy and carbon retrofits.

“Growing transition and physical risks combined with economic and geopolitical uncertainty, are creating headwinds for the building sector that did not exist 12-18 months ago,” says Thomas Mueller, CAGBC President & CEO. “In our ongoing efforts to scale retrofits, we are providing owners and investors with new insights, data, and transition planning resources to effectively close the gap between sustainability targets and core financing needs.”

Moving sustainability from corporate ambitions to financial balance sheets

Preliminary data from buildings in The Purpose Retrofit Accelerator suggests that when implemented on-schedule, transition plans could result in around a 40 percent reduction in greenhouse gas (GHG) emissions by 2030, at an average incremental cost of ten dollars per square foot. This initial insight is significant considering a lack of industry discussion or transparency on deep retrofit costs.

“The market lacks clear data on the upfront cost of meaningful building decarbonization retrofits,” says Eric Chisholm, Principal, Purpose Building. “Decarbonization can’t be – and isn’t – a blank cheque. Our inaugural dataset is starting to reveal cost trends that improve transparency and will help turn more sustainability ambitions into action.”

While these results are preliminary and based on subset of projects from The Purpose Retrofit Accelerator program, CAGBC and Purpose Building hope it will spark discussion, innovation, and collaboration across the Canadian commercial real estate sector.

A growing business case with real world examples

From the Accelerator’s first cohort, a clearer picture of the full impact and business case for deep retrofits is also emerging. Beyond lowered carbon emissions, newly published case studies show how asset managers navigated risk, cost, and complexity to deliver tangible outcomes from reduced carbon emissions to increased tenant satisfaction.

“The Purpose Retrofit Accelerator is a valuable program to encourage and accelerate energy efficiency and decarbonization investments,” says Mueller. “The emerging data, case studies, and stakeholder feedback demonstrate the significant impact of a well-thought-out transition plan and the business value of investing in decarbonization strategies.”

The Purpose Retrofit Accelerator Year 1 insights report and case studies can be downloaded on RetrofitsNow.ca. Future case studies, data and insights about Canada’s growing retrofit market, will continue to be published regularly on the site, so check back for updates.

7 Cedar Passive House


Winnipeg home designed for the next 100 Years

By Fletcher Noonan

Winnipeg will always be defined by climatic extremes. Annual temperature swings approaching 70°C are not anomalous but expected. In such a continental context, durability and performance are not aspirational qualities—they are prerequisites. Designing for longevity in this environment demands clarity of form, restraint of means, and technical precision.

7 Cedar Place was commissioned by a young family seeking a sunlight-filled home in a mature neighbourhood near the Red River. Their program was pragmatic and forward-looking: generous communal space for family life, quiet areas for work and study, and flexibility to accommodate evolving needs over decades. Equally important was a commitment to low-carbon living. The house needed to maintain comfort through Winnipeg’s severe winters and increasingly hot summers without dependence on oversized mechanical systems.

The project was therefore conceived to meet Passive House certification requirements. In a climate classified by the International Passive House Institute as “cold,” this standard demands rigorous control of heat loss, air leakage, and thermal bridging. Target heating demand and primary energy thresholds required an envelope-first approach, with airtightness verified through blower door testing achieving performance well beyond conventional construction benchmarks.

The architectural response is grounded in disciplined simplicity. The house takes the form of a truncated cube—compact, legible, and thermodynamically efficient. Minimizing exterior surface area relative to floor area reduces heat loss and simplifies air barrier continuity. The truncated roof form references the mansard geometry common in Winnipeg’s historic French-influenced neighbourhoods, moderates perceived mass at street level, and establishes an appropriate plane for future photovoltaic installation.

A continuous skin of lightweight metal shingles reinforces the monolithic reading while providing a durable, recyclable exterior system suited to harsh freeze-thaw cycles.

Structurally, the house draws from early 20th-century warehouse precedents common in Winnipeg’s historic Exchange Dist. A post-and-beam timber frame supports nail-laminated timber (NLT) “mill” floors, producing open and adaptable floor plates. Interior spaces are organized loosely around a nine-square grid, allowing structural clarity to guide planning.

The main floor accommodates a generous kitchen and dining space connected to a south-facing living area. The second level contains bedrooms arranged for privacy and connection, while the third floor—overlooking the river corridor and urban canopy—hosts a family room. A continuous track lighting system traces through the common areas across three levels, reinforcing spatial continuity and flexibility. The structural logic supports long-term adaptability, essential in a house intended to endure.

Material selection aligns durability with environmental responsibility. Natural linoleum flooring and window sills—manufactured from renewable materials including linseed oil, wood flour, and jute—provide resilience, repairability, and low embodied carbon. Ultra-compact Dekton countertops were selected for longevity and carbon-conscious life cycle initiatives.

A high-efficiency ERV by Mitsubishi Electric Sales Canada provides balanced ventilation with heat and moisture recovery. Passive House Institute cold climate certified windows (Innotech Defender 88PH+ XI) and cool temperate certified exterior doors (Innotech Defender 88PH+ Pro) by Innotech Windows + Doors are positioned within the centre of the insulation layer and specified with calibrated solar heat gain coefficients.

Decarbonization is reshaping Canada’s green building sector

A new market assessment confirms that green building and decarbonization are  delivering jobs for Canadians

Decarbonization is no longer a niche priority in Canada’s building economy: it’s becoming a growth strategy. A new report from the Canada Green Building Council (CAGBC), produced in collaboration with Delphi and funded by the Government of Canada’s Future Skills Program, finds that renewable energy  technology is a leading driver of projected job  and GDP growth in the green building sector,  alongside the broader shift toward low-carbon, high-performance buildings.

The findings are detailed in Building Prosperity: Insights on Canada’s Green Workforce, which describes clean energy and building performance as the main growth story for the sector’s next phase — and suggests Canada’s ability to capture the economic upside will depend less on ambition than on execution: predictable policy, dependable funding, and faster, clearer pathways from permitting to project delivery.

“The business case is clear: capital is moving toward superior building performance and resilience,” said Thomas Mueller, President and CEO of CAGBC. “If Canada provides long-term policy certainty and invests in skills and technology, the green building sector can scale and deliver major economic returns.”

A market that’s already sizable — and changing fast

The green building sector already supports an estimated over 500,000 jobs and contributes about $81 billion in direct GDP nationwide, it estimates.

What’s shifting, the report shows, is where the growth is coming from. As governments, utilities and building owners move to cut emissions, demand is rising not only for energy efficiency upgrades, but for the renewable energy technology and electrification capacity that makes low-carbon buildings possible at scale.

In practical terms, that means more activity — and more opportunity — across the ecosystem that delivers decarbonization: clean power, building electrification, and higher-quality construction and retrofit work that improves energy efficiency and resilience.

Predictability as a competitive advantage

CAGBC’s message to governments is less about announcing new targets and more about making the pathway to delivery reliable — particularly for the private capital and project pipelines needed to build at scale.

“What is clear from the report is that industry needs consistent policies and predictable funding pipelines to advance decarbonization and plan for workforce training,” said Laurna Strikwerda, Director, Project Development & Research at CAGBC.

Without clearer long-term signals, the report suggests, projects can stall and costs can rise — making it harder for firms to commit to equipment, hiring and training. The policy ask: consistent rules, stable funding, faster delivery.

The report calls for a more coordinated approach across governments and the market — aligning building codes, permitting, and financing so decarbonization projects can move from plans to construction with fewer delays.

While workforce issues remain part of the equation, the thrust of the analysis is that labour planning works best when the pipeline is real. Employers invest in skills when they can see projects coming — and when policy and funding frameworks are stable enough to support multi-year decisions.

As Canada tries to tackle housing pressures alongside rising climate risk, the report frames green building as more than an environmental endeavour. It’s an economic one — and the fastest gains will go to jurisdictions that make decarbonization investable, predictable, and deliverable.

Why this matters

Scenario modelling suggests Canada has already proven the market is real — but that the next wave of growth will hinge on whether the country can deliver energy-efficiency decarbonization projects at speed and at scale. There is a significant upside if governments and industry can pair predictable policies and funding pipelines with workforce initiatives that help people enter, complete and advance in green building careers. Done right, the report estimates the sector could support more than a million green jobs by 2030, alongside $150 billion in GDP.

“With broad alignment on technological pathways and a rising demand for sustainable building practices, the magnitude of impact now rests on Canada’s collective resolve to coordinate regulatory, financial, and workforce reforms,” Mueller said.

LEED offers formal exemption for tobacco smoke control for cultural ceremonial practices 

By Colleen Loader, Director of Technical Services at CAGBC

The Canada Green Building Council (CAGBC) recently shared that LEED Interpretation 10517 will allow for the seamless integration of Indigenous cultural ceremonies within the LEED certification process.

The LEED Environmental Quality (EQ) prerequisite Environmental Tobacco Smoke is intended to address health concerns resulting from second-hand tobacco smoke; however, it was never intended to prohibit or deter Indigenous cultural ceremonial practices which may include the combustion of tobacco and other ceremonial materials – such as when  smudging, which involves the burning of sacred medicines: tobacco, sage, cedar, or sweetgrass.

This LEED interpretation affirms that the prerequisite does not restrict this ceremonial practice, providing a clear path for projects to honor cultural ceremonies while maintaining LEED compliance. The interpretation applies to LEED v4 and LEED v4.1 projects, noting:

“An exception can be made for cultural ceremonial practices (e.g., smudging) which may include the combustion of tobacco and other ceremonial materials. Project teams may elect to incorporate design strategies or operational practices to manage the exposure of building occupants (who are not participating in the ceremonial practices) to ceremonial smoke, however, this is not a requirement of this prerequisite.”

A similar exemption is available for LEED v5 as noted within the reference guides under the EQ prerequisite No Smoking. CAGBC worked closely with USGBC on this issue, which was raised by Canadian projects and consultants, including Leanne Conrad, Sustainable Buildings + Climate Action Team Lead at Entuitive.

“On behalf of my clients, I am pleased to see the LEED rating system officially recognize this culturally significant practice which carries such an important weight in our communities,” Conrad shared.

“It’s encouraging to see LEED clearly acknowledge that environmental health goals and Indigenous cultural practices are not in conflict,” said Adam Stoker, Senior Sustainable Infrastructure Engineer with the City of Calgary, and chair of the USGBC LEED Design + Construction Consensus Committee. “Having had the opportunity to advocate for this perspective through the USGBC review process, I’m pleased to see it reflected in an interpretation that provides clarity while reinforcing the importance of culturally respectful, healthy building design.”

Exterior details for High-Performance Enclosures

Rear-Ventilated Rainscreen (RVRS) and Cladding Types

Jeff Ker, Engineered Assemblies

Facades systems have always been one of the most important parts of sustainability. We are only now coming around to realize just how important. Facades, if done properly, will be a rear ventilated rainscreen. They will be part of an outboard insulated envelope and will be high performance. In keeping with that methodology, they will then be the Primary Passive Environmental Control System.

Facades have always been on the front lines so to speak. They are often the single largest building component charged with insulation in addition to being most vulnerable to the substantial dictator – the environment.

Managing the abuse the environment delivers is a holistic endeavour and is only possible with a combination of materials, good design and proper assembly. If we had to pick one ingredient to start with, ventilation is the first. Whether you have a marginally absorbent façade material or not, ventilation is always good – never bad. It helps the entire assembly maintain a handle on moisture.

Having an active plenum, as outlined in the drawing detail, ensures the circulation of air is constant in good times and bad. The plenum can only function best when unobstructed and with the combination of adequate intake and exhaust vents.

Having adequate ventilation/air flow means the substructure supporting the façade material can see a longer lifespan and the insulation can function at its maximum potential in its dry state.

Placing a secondary drainage plane in front of the insulation (behind the plenum) will further thwart the intrusion of precipitation, minimize wind washing, and provide a visually pleasing veil to hide substructure and insulation through open joints of facade panels.

When all the components are chosen and assembled in the spirit of achieving their greatest lifespan, we can avoid premature demolition and concentrate on maximizing thermal performance and moisture management. This, in itself, is a pathway to sustainability.

VIEWPOINT: High-Performance Design as a Stress Test for Specifications

High-performance design targets are no longer exceptional. Metrics tied to energy use, airtightness, thermal continuity, and long-term operational performance are now common expectations on institutional, residential, and mixed-use projects. Frameworks such as Passive House have helped formalize these ambitions, providing a clear benchmark for what “performance” is meant to achieve.

Why High-Performance Projects Are Less Forgiving

Conventional projects often absorb documentation gaps through informal coordination, substitutions, or site-level problem solving. Tolerances are wider, expectations are less explicit, and outcomes are rarely tied to third-party verification.

High-performance projects operate differently. Performance targets are precise, tolerances are narrow, and compliance is confirmed through testing, modelling, and external review. Verification occurs against defined thresholds and fixed timelines, leaving little opportunity to reinterpret intent once construction is underway.

The result is not that high-performance projects are inherently more complex, but that they are far less tolerant of incomplete or poorly coordinated documents.

Specifications as the Performance Translation Layer

In this context, the role of specifications becomes clearer. Drawings communicate design intent. Specifications establish obligation.

Specifications translate performance goals into enforceable requirements by defining acceptable products, required submittals, testing protocols, and verification responsibilities.

Contrary to common perception, Passive House or other high-performance targets do not require a fundamentally different approach to writing specifications. The structure remains largely the same. What changes is the level of precision required. Performance thresholds must be stated clearly, submittal requirements must align with certification milestones, and testing obligations must be unambiguous.

Specifications make performance contractual.

Where Weak Specifications Fail Under High-Performance Pressure

Performance targets are often referenced without clearly defining how they will be verified. Testing requirements may be mentioned, but responsibility for coordination, scheduling, and cost is left vague. Submittals are requested without regard for when they are needed to support modelling, mock-ups, or certification review. Drawings and specifications begin to drift out of alignment, resulting in confusion and reactive site instructions.

On high-performance projects, they become immediate points of friction. Contractors are asked to price uncertainty, and consultants are asked to resolve questions late in the process. Certification pathways narrow as documentation fails to anticipate verification needs at the appropriate stage of work.

The issue is not that the specifications are wrong, but that they are insufficiently disciplined for the performance demands placed upon them.

What a Coordinated High-Performance Specification Signals

From a specification reviewer’s standpoint, certain indicators reveal whether performance intent has been properly embedded into the Project Manual or merely referenced in passing.

The first signal appears early, in Division 01. Well-coordinated high-performance projects typically include General Requirements sections that explicitly address performance testing, verification, and closeout documentation. Sections such as Section 01 83 16 Exterior Enclosure Performance Requirements and Section 01 78 53 Sustainable Design Closeout Documentation establish expectations up front by identifying required testing, certification pathways, and documentation deliverables tied to stated performance goals. Their presence signals that performance outcomes are being managed intentionally, not deferred.
