Not the End of the World
In a year when the environmental news about global warming, biodiversity loss, plastic pollution, air pollution, deforestation and multiple other metrics was all bad, it was refreshing to read the more optimistic view put forward by data scientist Hannah Ritchie in her recently published book ‘Not the End of the World’.
Opening with a review of the Bruntland Commission’s definition of sustainable development as "meeting the needs of the present without compromising the ability of future generations to meet their own needs", Ritchie asks us to zoom out and look more broadly at both the social and environmental implications of that definition.
If we accept that human health and wellbeing legitimately fall within the definition of present needs, then our progress over the last century or two is remarkable. Whether we consider child mortality, mothers dying, life expectancy, hunger and malnutrition, education or extreme poverty, the trend is relentlessly upward.
Rennie’s optimistic outlook on the social side of the equation, does not deny the scope of our challenges on the environmental side, which she freely admits has gotten much worse over the past century. However, she does emphasize the progress that has been made at the local, regional and sometimes global scale.
For example:
• The air quality in developed countries is better than it has been in more than a century.
• With the cost of renewable energy decreasing rapidly, economic growth will soon be decoupled from GHG emissions.
• Measured globally, the rate of deforestation, mostly associated with agriculture, is declining rapidly, which should soon slow the rate of biodiversity loss.
• The challenges around food are not about quantity, but rather our dietary choices and the waste in our distribution systems. Both these challenges can be addressed.
• Both a miracle material and an environmental disaster, plastic pollution has almost been eliminated in countries with strict regulations on manufacture and disposal.
• Aquaculture now supplies more than 50% of fish and seafood consumed globally, relieving the pressure on wild fish stocks
It is not the solutions themselves, but the scaling up of these solutions that is the major challenge we face.
Ritchie concludes, ‘these problems are big. But they are solvable. We are not doomed. We can build a better future for everyone. Let’s turn that opportunity into reality.’

LOCAL NETZERO BUILDINGS:
A bottom-line win for Canadian communities
Put sustainability and savings—and comfort—at the top of the list for the coming year
Resilient futures are based on resilient economies, and municipalities across Canada are realizing how closely sustainability initiatives are intertwined with cost savings, job creation and economic growth. Working toward a more sustainable future doesn’t just support Canada’s climate goals and create healthier communities. It can also improve budgetary bottom lines.
Municipalities large and small are joining forces with architects, designers, engineers, contractors and building developers to reduce energy consumption and move to cleaner energy sources. Take aging municipal and community buildings. Almost 70 percent of the buildings in Canada that are central to thriving communities, such as town halls, fire stations, recreation centres, arenas and libraries are more than 30 years old, with the correspondingly higher operating costs and greenhouse gas emissions (GHG) that come with age. Retrofitting these facilities can lead to a net positive return on investment — not to mention the comfort and health benefits stemming from improved air quality, fewer drafts, enhanced lighting and better all-around functionality.
Enter the Green Municipal Fund (GMF), a program of the Federation of Canadian Municipalities. Through a unique combination of financing and training, GMF is accelerating the transformation to resilient, net-zero communities. With GMF’s sustainable community and municipal buildings funding, Canadian municipal governments and their partners* are experiencing the benefits of GMF support as they:
• Undertake retrofits to improve energy performance, lower operating and maintenance costs, transition to cleaner energy, extend building life and make buildings more livable through, for example, efficient lighting and windows, fuel switching from fossil fuels to lower-carbon fuels, insulation upgrades, electric boilers, automation systems and solar panels.
• Construct new builds that meet ambitious energy efficiency targets, use sustainable materials, and improve biodiversity and ecological function.
GMF encourages innovation and creativity across the sector, guided by a vision of how the most successful sustainability efforts integrate environmental, economic and social factors. Since its inception in 2000, GMF has taken a multi-solving approach to project selection and performance monitoring, seeking projects that combine multiple objectives in a single solution, so municipalities save money even as they meet their sustainability goals and improve citizens’ lives.
North Battleford feasibility study focuses on cutting energy consumption
The City of North Battleford in Saskatchewan put GMF funding to good use by conducting a feasibility study to explore ways to reduce its carbon footprint and curb energy consumption in five energy-hungry buildings: the wastewater treatment plant, the aquatic centre, a sports complex, the curling rink and the performing arts centre.
The study analyzed historical data for the five facilities, conducted energy audits and evaluated retrofit options. The goals were to cut energy consumption by reducing energy use and GHG emissions and exploring alternative energy sources, as well as decrease operating costs, improve workspaces and stimulate the economy with new jobs. Myriad energy-efficiency measures were considered, from operational changes to LED lighting, equipment improvements, building envelope retrofits and, in a first for the city, generating renewable energy through solar power and locally sourced biomass.
Today, other municipalities are learning from North Battleford’s experience as they develop their own innovative solutions to cut energy use and save money.
GMF offers more than just grants and loans. It also provides learning opportunities through the GMF Learning Centre, including practical guides, webinars, training, advisory services and even a project database that showcases the results and replicability of sustainability projects across Canada.
Extend the life and efficiency of your buildings today, with help from GMF. Visit bit.ly/gmf-buildings.

Daylighting
To be most productive, one needs to be comfortable first. Add superior light quality and views to the outdoors along with natural ventilation to enhance indoor environmental quality and people thrive. Daylighting done right has been proven to increase productivity, reduce absenteeism and improve mood. Kalwall works hard so employees can work smart.
Only Kalwall offers the power of beautifully balanced daylighting. Unlike other glazing products on the market, Kalwall provides predictable, glare-free daylight that blocks harmful UV-A and UV-B rays while transmitting the full spectrum of visible light for perfect color rendition within interiors.
productivity balance sustainability
Translucent Kalwall panels provide perfectly diffuse daylighting that evenly bathes spaces in natural light, meaning fewer lights on during the day. Our high recyclability and low embodied carbon ratings are planet-friendly. Even better, our best-in-class thermal performance means you get superb daylight without any solar heat gain. That means savings for electrical and cooling costs, which is good for both your bottom line and the environment.

ECOLE DU ZENITH
New school a harmonious fusion of education and nature
In partnership with Leclerc Architects, Montreal-based Pelletier de Fontenay has recently completed École du Zénith in Schefford, QC, a project resulting from a series of competitions launched by Lab-École in 2019. Being the first school architecture competition since the 1960s, this major project marks a turning point in Quebec’s educational landscape, renewing the program, organization, and way of building elementary schools in the province.
The school pavilions are assembled around an inner courtyard.
THE DIVIDENDS OF DISASSEMBLY: Reclaiming the value held in buildings
By Brenda Martens
Design for Disassembly and Adaptability (DfD/A) is an approach that facilitates dismantling a product or building at its end-of-use, enabling the recovery of components and materials intact, to facilitate their use in subsequent applications, including complete reassembly. The goal of DfD/A is to keep materials in their highest use for as long as possible.
HISTORICAL HIGHLIGHTS
The concept of DfD/A in permanent buildings isn’t new. Indeed, there were industrious (and perhaps morally suspect) parishioners in the 1500’s in Appenzell, a canton in the Swiss Confederacy, constructing homes on their lots, taking advantage of the free lumber from the church-owned forests offered to the congregation for this purpose, then disassembling these houses to sell to others, to be relocated and reassembled on a new site.
Even earlier, in Japan, techniques for carpentry (Miyadaiku) allowed for the removal and replacement of the wooden elements of construction. The dismantling, repairing or replacing, and reassembling of the timber parts has resulted in some wooden temples standing for centuries, largely replaced in place. The Hōryū-ji temple, over 1,300 years old, is the oldest standing wooden structure. After many restorations, only roughly a fifth of the original materials remain.
CANADIAN CONTEXT
Closer to home and our own time, the C.K. Choi Building at UBC (’96) is a striking early and influential project that demonstrated circular design principles. Under the direction of architects Joanne Perdue and Eva Matsuzaki and structural engineers Diana Klein and Gilbert Raynard, the project aspired to, and succeeded in incorporating salvaged heavy timber from the Armoury Building next door that was slated for demolition.
The Armoury, built in 1941 and used for military training in World War II, was repurposed after the war by UBC for registration, sessional examinations, graduation ceremonies and other assemblies but no longer fit with campus master plans. It provided approximately two thirds of the CK Choi’s structure, but only after the structural engineers had regraded all of the salvaged timber appropriate to its future use, with the knowledge of where it would be used in the new building, overruling the lumber grader’s previous conservative grading.
1
This, along with the brick façade salvaged from Yaletown buildings, doors, toilet partitions and accessories, stair and balustrade railings, electrical wiring and other reused components resulted in more than 50% of the building’s materials being salvage or having recycled content. The C.K. Choi in turn incorporated disassembly into the design, with both the heavy timber structure and interior partitions mechanically connected with very minimal finishes, and building systems and services exposed. But we shouldn’t expect to see these materials on the market any time soon, as the C.K. Choi was built with a 200-year service life.
More recently, StructureCraft has constructed their head office and workshop in Abbotsford BC as a showcase for timber construction, being built with glulam, LVL, and nail-laminated timber. Inside that same workshop, the firm’s sister company DowelLam now produces an all-wood mass timber product called dowel laminated timber (DLT, which harkens back to the Japanese carpentry techniques of using wood connectors rather than glue and nails). Although intended to be permanent, the headquarters was designed to be dismantled and has already been expanded once.
Their sublime Sycamore & Oak Retail Pavilion project, a 23,000 sqft open air structure in Washington DC, however, is temporary, meant to stay in its current location 5 or more years before being relocated. While temporary, it must still be durable in order to withstand disassembly and reassembly. From a whole life cycle perspective, the circularity of the project is further enhanced by the entire timber structure being crafted from FSC-certified Douglas Fir, ensuring both the forests and the building are there for future use.
1. Traditional Japanese joinery has facilitated the replacement of individual structural members of the Horyu-ji temple since its construction in the 7th century.
SUSTAINABILITY & CARBON
The Masonry Industry Perspective
By Monica Guzman
As the design and construction industry focuses more intently on reducing the embodied carbon of buildings, masonry manufacturers and manufacturer associations are actively working on developing Environmental Product Declarations (EPDs) to assess and improve the environmental impact of their products. Many of them have already introduced innovative and proprietary technologies aimed at reducing the embodied carbon of masonry construction.
More broadly, the masonry industry is focusing on reducing the carbon footprint through efficient design and specifications, enhancing the energy performance of masonry assemblies, and raising awareness about the energy saving potential of their inherent thermal mass. At the same time, ongoing research is exploring the carbon sequestration capabilities of concrete masonry throughout its service life.
EMBODIED CARBON REDUCTION: CONCRETE MASONRY UNITS
Manufacturers of concrete masonry units (CMUs) are currently developing EPDs for their products, some of them already published their plant specific EPDs, and more are on the way. At a national level, both the concrete block and clay brick associations published industry average EPDs.
For example, the Canadian Concrete Masonry Producers Association – CCMPA published average EPDs for eastern and western Canada. These Type III environmental declarations present quantified, third party verified, environmental information on the life cycle of a product – or in this case, a product type. This, and plant specific EPDs, will enable specifiers to make comparisons between various products fulfilling the same function.
CCMPA has also published a Canadian Industry-Average Cradle-to-Gate Life Cycle Assessment (LCA) for both normal weight and lightweight CMUs. This LCA was completed to support the development of the Type III EPDs for concrete masonry units conforming to CSA A165.1-04 – Concrete Block Masonry Units, and as part of CCMPA's commitment to providing transparent information about the environmental footprint of concrete block masonry units produced in Canada.
ALBERT CAMPBELL Library Renovation/ Modernization
Reno reimagines potential to connect with people
By Brock James
The Albert Campbell Branch Library opened its doors in 1971 to serve Scarborough’s diverse community. In this rapidly growing Toronto suburb, the brutalist building stood as a beacon to the community. But after five decades, the Toronto Public Library (TPL) recognized the need for upgrades to meet contempo-
rary needs. Working with LGA Architectural Partners, TPL sought to reimagine Albert Campbell as a more welcoming hub that brings people together and is connected to the community.

təməsewtxʷ Aquatic and Community Centre
Challenging building type achieves double certification, and pursuing LEED Gold
By Paul Fast
Completed in 2024, this 10,684 sq.m combined aquatic and community centre in New Westminster, BC is Canada’s first completed all-electric facility to achieve the Canada Green Building Council’s (CAGBC) Zero Carbon Building Design standard, a significant accomplishment for a building typology that has traditionally been one of the largest greenhouse gas emitters for many local governments.
The name təməsewtxʷ is derived from hənqəminəm (the local Indigenous language) and means “Sea Otter House”. Reflecting this Indigenous identity reflecting this indigenous identity, the building is woven into the landscape with a dramatic unifying roof and aims to be the heart and soul of the community and a place for all to connect. The building makes a strong civic statement being sensitive to the natural environment and humanscale experience.
SUSTAINABLE DESIGN STRATEGIES AND PROCESS
Pools are one of the most energy-intensive building types. To successfully minimize energy use, the design strategy for təməsewtxʷ applies a passive approach first, considering not only how the architecture can respond to specific site conditions for efficiency and comfort, but how operational conditions, strategies, and expectations inform the design. Reducing demand first, followed by optimizing active systems, ensures a low impact result.
To meet the stringent LEED v4 and Zero Carbon Building (ZCB) requirements, a range of strategies were implemented to reduce energy consumption and greenhouse gas emissions.
The building's compact massing and form factor were shaped by site conditions, with the existing facility required to remain operational during construction, and the need to avoid critical infrastructure running through the site. 1. The aquatic and
community centre is Canada’s first all-electric facility to achieve the CAGBC’s Zero Carbon Building Design standard.

INTERVIEW WITH …
WHAT IS THE CBE?
Architect Vince Catalli on the Circular Built Environment (CBE) and the new standard to define it.
Circular is the key word in defining the CBE which is modelled after cycles in nature that continuously use and transform materials without waste. According to the World Green Building Council, a circular building optimizes the use of resources while minimizing waste throughout its whole life cycle. The building’s design, operation and deconstruction maximize value over time using:
1. Durable products and services made of secondary, non-toxic, sustainably sourced, or renewable, reusable or recyclable material;
2. Space efficiency over time through shared occupancy, flexibility and adaptability;
3. Longevity, resilience, durability, easy maintenance and reparability;
4. Disassembly, reuse or recycling of embedded material, components and systems; and
5. Life-cycle assessment (LCA), life-cycle costing (LCC) and readily available digital information (such as BIM that capture building material passports)
THIS SOUNDS LIKE WASTE MANAGEMENT AND REDUCING EMBODIED CARBON, WHAT IS THE DIFFERENCE?
Waste Management and reducing Embodied Carbon are components of CBE. The CBE proposes systemic changes in business models which have historically been linear by using many integrated approaches (i.e. durability, waste reduction, refurbishment, remanufacturing, recovery, reuse, reduction of embodied carbon, etc.).
Pursuing the CBE is critical for North America to stay competitive with other nations (i.e. the EU, Japan, Australia, etc.) that are already working towards the CBE. Eliminating waste is very cost effective and good business.
WHY ARE YOU INVOLVED WITHIN THE CBE NATIONAL DISCUSSIONS?
Since 1994 I have focused on new approaches within our industry that were precursors to CBE:
• I looked at Deconstruction via a pilot project for Canada Mortgage and Housing Corporation (CMHC) in 1996 which then led me to develop a Design for Disassembly and Adaptability guide in 1998.
• I was part of a committee that developed two new standards with Canadian Standards Association (CSA) (Z782-06 and Z783-12). These were global firsts that led to international developments in ISO Standards.
WHY A DEFINITION ORIENTED CBE STANDARD?
In my recent work (2021) with CSA, I spoke with various private and public stakeholders from across Canada. I found that the CBE was unfamiliar to them, but they were unknowingly engaging with or operating in circular systems. They spoke of circularity in terms of waste management, Net Zero, embodied carbon, CO2 reduction, climate change, resilience, etc. Everyone was using different terms and approaches, lacking cohesion on a national level. A standard to define the CBE will give all actors in the building industry unified tools to focus our attention, coordinate and mobilise in ways that create lasting change.
WHY IS IT IMPORTANT TO MOVE THE CBE AHEAD NOW?
Our industry consumes about 50% of virgin resources extracted annually and produces close to 40% of global CO2 emissions. Finite resources will become scarce and climate change will impact how we build due to wasted embodied carbon. CBE will allow industry to redesign our approach to materials applied in construction, factoring in disassembly and adaptability so that we recover materials. We cannot continue as is, we need to recover value and “future proof” building assets. It just makes sense, right?
WHAT CAN THE BUILDING INDUSTRY DO TO MOVE THE CBE AHEAD?
All stakeholders need to learn about the CBE with the goal of achieving systemic change. This will lead us into action, education, new skills and application, required collaboration throughout the industry. Much like the early 2000s with green buildings, the CBE will lead us into the next chapter. A national discussion is needed to review how this will emerge. I don’t see an option but to get involved as we all have a role to play.
The MEC store in Ottawa is likely a first example in Canada that used the Design for Disassembly and Adaptability approach back in 1998 – 1999.
Total Precast Concrete Key Attributes to Passive House Development are:
· Manufactured in local precast facilities under controlled conditions
· The whole building envelope in one composite panel; air barrier, moisture control, insulation and the structure
· Hollowcore floor slabs allow for a much lower depth to span ratio
· Hollowcore provides the lowest GWP per m2 of concrete floor area
· Precast concrete dramatically reduces the construction schedule, site congestion, noise and environmental impacts
