2024 Canadian Green Building Awards
This issue of SABMag celebrates the winners of the 2024 Canadian Green Building Awards. Established in 2008, this awards program continues to provide a fascinating window into the evolution of sustainable design in Canada.
We would like to thank the jurors: Daniel Ling of Montgomery Sisam, Sindhu Mahadevan of MGA-Michael Green Architecture, and Peter Osborne of GEC Architecture, for devoting their time and invaluable expertise to the process. The winning projects were selected from a field of more than 40 submissions and reflect the current priorities and best practices of architects, clients and the wider industry.
The growing concern for conserving the embodied carbon of existing buildings and reducing the demand for the extraction of new materials was shown at a variety of scales and in multiple contexts: Little by Little Studio in Winnipeg, MB; the Ministry of Children and Family Development in Williams Lake, BC; and the McLeod Engineering Building renewal on the Vancouver campus of UBC.
Three small housing projects caught the attention of the jury for their modest scale, healthy, low-carbon material choices, energy performance and long-term thinking: Gabion House near Victoria, BC; Bird’s Wing PH Duplex in Vancouver, BC; and the Heimaklettur House in Langley, BC.
A combination of superior energy performance, elegant and effective passive design strategies, economy of means, and a particular focus on occupant wellbeing characterize the other winning projects: The Foxglove Supportive Housing in Surrey, BC; Cheko’nien House Student Housing and Dining facility at the University of Victoria, BC and the Windermere Fire Station 31 in Edmonton, AB.
In addition to congratulating these project teams for their winning entries and thanking all the other teams who submitted this year, we also thank ecohome.net for helping to publicise the Awards, and to especially acknowledge the sponsors who enabled us to host the awards program again this year: our National Sponsor, the Canadian Precast Prestressed Concrete Institute, along with our Category Sponsors noted below.

RAIC REPORT
2024 Conference Highlights
By Giovanna Boniface, Chief Commercial Officer
The 2024 RAIC Conference was our largest in-person gathering since Covid, providing the opportunity for many in the architectural profession to engage in unique learning experiences, listen to distinguished guest speakers, and network with colleagues from across the country. From May 14-18 this year, architects, interns, students, and associates from Canada and abroad converged in K’emk’emeláy/ Vancouver for the Conference.
This year, Conference featured more than 50 in-depth education sessions, as well as keynotes that discussed topics such as climate, EDI, Indigenous-led architecture, social justice, and accessibility.
The event kicked off with an exhibition on iconoclastic Vancouver Island architect John Di Castri, providing an opportunity to explore a distinct chapter of the architectural history of Western Canada. The first day ended with a keynote presentation by James P. Cramer, Hon. AIA, titled “The Future of the Profession”.
Examples of some of the twelve sold out tours include a downtown Tall Buildings tour with architecture critic Trevor Boddy, a visit to Patkau Architects’ award-winning Polygon Gallery, as well as a oncein-a-lifetime pop-up tour of the Arthur Erickson-designed Smith House II, recently renovated by Measured Architecture, in West Vancouver.
On the networking side, Conference hosted a studio crawl featuring five local firms—Kristen Reite Architecture, MA+HG, McKinley Studios, Omer Arbel and a large social gathering at DIALOG. This year we inducted new members to the RAIC College of Fellows, welcoming five honorary Fellows and 41 new Fellows to the College.
The Conference ended on a high note with the After Parti, where six small Vancouver architectural firms— MOTIV, ph5, Twobytwo Architecture Studio, WNDR and TOAD—partnered with local artists to deliver a breathtaking Beaux Arts Ball performance concept.
The RAIC is deeply thankful to everyone who contributed to the success of this year’s Conference, including volunteers, presenters, tour leaders, special guest speakers, exhibitors, architectural firms and sponsors. We could not have put on this amazing event without everyone’s support. Let’s meet again at the 2025 Conference—next year in Tiohtià:ke/ Montréal—to make more great connections and memories.

“I love the collaborative aspect of the program”
Free expertise and assistance, all at no cost
The Enbridge Gas Savings by Design program * provides free building science consulting offered over a full-day integrated design process workshop to help build high-performance and sustainable buildings. BDP Quadrangle’s Director of Innovation, Michelle Xuereb, shares why she’s a longtime participant.
QAs an architect, what’s the value of participating in Savings by Design?
A: The real value comes from the integrated discussions. The program brings together a diverse group of stakeholders including the client, their design team, subject-matter experts and energy modellers provided by Enbridge Gas. We spend the day together outside our day-today environment, which allows us to focus our attention on solving complex design issues informed by real-time energy modelling.
To get the most out of your next project, contact Venoth Jeganmohan, Energy Solutions Advisor.
QHow is the program different from simply bringing in consultants?
A: I think the difference is that the workshop is peer to peer. For example, a mechanical engineer with sustainability expertise may present new technologies and ideas to the project mechanical engineer in the room. It may be a technology that is new to the team or it may be something they were already considering and now have the support to bring forward. I love the collaborative aspect of the program.

UBC MACLEOD ENGINEERING BUILDING RENEWAL
Vancouver, BC
JURY COMMENT:
“An incredible transformation of an existing building. While much of the upgrade is technically driven, elements such as solar shading have been used to reimagine its Modern identity. The transformation continues on the inside, with new daylighting and ventilation strategies opening up the spaces.”
1. The project transforms a 1963 building nearing the end of its service life into a future-focused, high-performance facility.
The MacLeod Building renewal is the most comprehensive retrofit project completed at UBC to date. Driven by a pressing need to improve the seismic and climate resilience of the campus’ modernist architecture, the project transforms a 1963 building nearing the end of its service life into a futurefocused, high-performance facility that actively supports and showcases 21st-century learning. Home to the Department of Electrical and Computer Engineering (ECE), MacLeod accommodates teaching, research, and administrative s paces as part of a growing Applied Science precinct.
The previously dark and inward-facing building has been transformed through thoughtfully reconfigured interior and exterior glazing and key measures such as the creation of a welcoming, fully accessible main entry. Complete interior reconfiguration supports evolving pedagogy and research practice through the introduction of extensive visual and spatial interconnection, new active learning and research space, and strategically distributed Informal Learning Spaces (ILS) as collaborative focal points.
Comprehensive renewal represents a holistic sustainability approach: achieving substantial carbon savings through the reuse of 73% of the building’s existing concrete structure; enhancing seismic, climate and operational resilience through benchmark-setting upgrades; avoiding the ecological impact of a re-build or development on a new site leveraging established infrastructure and transportation networks; replacing an inefficient envelope and building systems with high-performance design; and establishing reimagined, enlivened spaces focused on community, inclusion and accessibility.
Working with existing orientation and massing, the project efficiently combines passive approaches with active systems, integrating solar shading, high SHGC glazing with operable windows and a newly created light and air shaft that acts as the primary return air path for the entire building, connected to rooftop heat recovery units. The envelope and HVAC system were optimized using 2050 weather file energy modelling to ensure future climate resiliency.
The light and air shaft uses the stack effect to reduce fan energy loads, limiting the need for costly, space-consuming ductwork, while introducing visual interconnectivity between floors. Mechanical upgrades include the use of high-efficiency HRVs, demand control ventilation and air-source heat pumps with auxiliary from the District Energy System.
Marmoleum connects with modern nature through climate positive ooring and contributes to everyone’s well-being. An endless source of inspiration, from the natural materials we use, to the colors and designs we o er.
We invite you to create sustainable spaces that have a positive impact on everyone and everything.
View our new Marmoleum Solid collection at www.forbo ooringna.com/marmoleum
A new, sculptural precast concrete envelope features integral solar shading through panel facets and operable windows in all program spaces. On south and west exposures, a light shelf combined with high SHGC glazing mitigates glare and heat gain while bouncing light deep into the floor plate. Ample glazing between perimeter programs and corridors allows natural light penetration into a previously dark, inward-facing interior. Floorto-ceiling curtain wall glazing at strategic points maximizes transparency, highlights social spaces, and animates interior circulation.
A core goal was to enhance a sense of community within ECE, encouraging intellectual exchange and occupant wellbeing with a key focus on accessibility and inclusion. The existing building was designed for only one gender and did not reflect diversity in the engineering field. The renewal introduces gender inclusive/ universal washrooms on all levels, safe, bright and accessible entries and interior circulation.
Reflecting the contemporary diversity of the student population, the MacLeod Building renewal also includes a multi-purpose prayer and meditation room.
4. Some of the renewal measures include the reuse of 73% of the building’s existing concrete structure and replacing the inefficient envelope and building systems. Fibreglass-frame windows were supplied by Cascadia Windows & Doors.
5. Reconfigured interior and exterior glazing allows for more natural lighting. Much of the new resilient flooring is Forbo Marmoleum.

FOXGLOVE SUPPORTIVE HOUSING AND SHELTER
Surrey, BC
JURY COMMENT:
“This complex program of shelter, supportive housing and health services, so important to social sustainability, is appropriately contained in a simple form with a calming character. Material choice and detailing are thoughtful, with horizontal and vertical solar shading balancing the overall expression.”
1. The concrete construction ground floor is articulated along its façade, creating a rhythm of solid and void, while the recessed upper floors of wood-frame construction appear to float above the ground floor.

Since 1982, RainCity Housing and Support Society has addressed the needs of individuals living with homelessness, mental illness, and addiction. To address these needs in the City of Surrey, RainCity has developed this facility in Green Timbers Park, in partnership with BC Housing, the City of Surrey and Fraser Health.
The project encompasses three major components:
• The Shelter, which offers emergency housing and care to those navigating homelessness, mental health, and substance abuse.
• Supportive Housing, which provides a caring residential environment for those who have attained stability and are transitioning to permanent housing.
• Enhanced Health Supported Housing, in which Fraser Health and RainCity work together to address both homelessness and complex health needs.
All three programs provide 24-hour/7-day staff with access to medication, overdose prevention services, and indigenous cultural and peer support. The design response reflects RainCity’s and BC Housing’s commitment to environmental sustainability, and implements strategies established through integrated workshops, extensive energy modelling, and costing exercises.
By using simple forms and optimizing the exterior envelope, the building easily meets BC Building Code Step Code 3. The envelope is highly insulated, has a low window-to-wall ratio, energy-efficient windows, and vertical and horizontal solar-shading systems. Detailing concentrated on eliminating thermal bridges and maintaining continuous high insulation values. These passive design strategies work together to optimize energy performance.

These passive design strategies work together to optimize energy performance. Various conditions informed the linear design concept of the building: the long, narrow site, Surrey’s requirement to provide building access off Foxglove Drive, and the complex program. The simplicity of the building’s massing and character is intended to create a calm atmosphere for both its residents and the surrounding community.
To get the most from the budget, and to reduce its carbon footprint, the building was designed as a six- storey structure with five levels of wood frame construction over a concrete ground floor and a single level of underground parking.
The narrow linear plan allows all areas of the building to receive a significant amount of natural light. Almost 100% of the occupied floor area is within seven metres of an operable window. In addition to natural ventilation from these windows, two high-efficiency HRVs provide mechanical ventilation to all living units at a rate of 1.0 AC/hr.
The mechanical, electrical, and lighting systems are integrated and connected to a Building Management System which monitors and controls energy usage.
As owner operators, durability and low operating costs are critical to RainCity and BC Housing. The building is designed for a 60-year service life, and the ground floor amenity area is designed for easy reconfiguration should programs and priorities change. Internally, careful attention was paid to material specification, with preference given to high recycled content, as well as low-VOC adhesives, paints, coatings, sealants and flooring.
Externally, the site’s surface is largely permeable. This mitigates rainwater runoff and alleviates strain on the city’s stormwater infrastructure. An on-site stormwater detention system is concealed beneath the landscape area along Green Timbers Way. Drought-tolerant indigenous planting reduces reliance on irrigation.

Located in Williams Lake, a city of 10,000 in the Cariboo Region of BC, this project represents the transformation of a 1500 sq.m singlestorey retail building into a NetZero Carbon Neutral office for the provincial government. It incorporates a suite of tenant Improvements, base building upgrades and energy retrofits. Together, these strategies enable the project to meet the GHG reduction requirements mandated by BC’s Climate Change Accountability Act, while at the same time following the Blueprint and Real Property Division guidelines for innovative service delivery.
For the energy retrofit, Passive House design techniques were implemented such as high efficiency triple-glazed windows on the southeast and west facades, enhanced thermal insulation, and the minimization of thermal bridging.
Internally, communal areas were strategically located near these windows with enclosed spaces positioned in the centre. Solatube skylights flood the interior with natural light, while the operable argon-filled windows with low-e coatings reduce reliance on mechanical systems and offer occupants environmental control.

3. Once home to Sears and Fabricland stores, the refurbished building offers a vibrant and inviting environment. The building is equipped with a high-efficiency central ERV system by Winnipeg-based Tempeff. Acting as the building’s lungs, the ERV not only recovers heat, but also factors in humidity making it an excellent choice for occupant comfort in a cold climate. The ERV makes use of Dual-Core technology, allowing for continuous fresh air supply and frost-free operation in this climate.
These high-performance windows (with a U-value of 0.15 or R-6.67) enabled the window-to-wall ratio to be increased from 5% to 20%, enhancing both energy efficiency and occupant comfort. The existing mechanical and electrical systems were upgraded to highly efficient systems with geothermal heating and cooling capabilities.
Based on these upgrades, the energy model predicted a reduction of up to 80% in energy consumption relative to the baseline building. To achieve Net-Zero Energy, the building then offset the remaining 20% of energy consumption through on-site renewable energy in the form of solar photovoltaic (PV) modules covering most of the roof. The project is now certified Zero Carbon Building by CAGBC (V2 – Design Standard).
The daylighting strategies noted above were part of a much-needed redesign of the interior spaces. This redesign integrated WELL principles for occupant health and well-being, Rick Hansen Foundation principles for accessibility, and strategies to enhance Indigenous inclusion.

Mixed Use Award
CHEKO’NIEN HOUSE
University of Victoria, BC
JURY COMMENT:
“This project is notable for its richly mixed program; including student housing, academic areas and food services. Innovative and progressive, it makes a positive contribution to social life on the urban campus. Selective use of large windows and exposed wood in areas where people gather reinforce their connection to nature.”
1. The housing entrance is located on the new north-south greenway that connects the residential district.
(Cheko’nien House), the first of two buildings in the Student Housing and Dining project at the University of Victoria (UVic), embodies a transformative approach to student living and community engagement. Its unique design emphasizes social connectivity and sustainability.
Site plan
New building massing frames new housing commons. Landscape infills to adjacent buildings, reorganizing and reconnecting the pedestrian realm.
The first two storeys house a 600-seat dining hall, a multi-purpose room for 200, a servery, and a commercial kitchen, fostering vibrant community interaction. Above, the 398-bedroom student residence offers modern living spaces tailored to promote student well-being and academic success.
Driven by a steadfast commitment to climate action, Cheko’nien House meets rigorous sustainability standards, including BC Energy Step Code Step 4 and LEED v4 Gold certification, and is on track for Passive House certification. This dedication not only reduces campuswide CO2 emissions, but also enhances the health and comfort of its residents.
2. An extension of the dining space, a multi-purpose room overlooks Ring Road and shelters outdoor public space.
3. Propelled to preserve greenspace while meeting the growing demand for on-campus housing, the building has a compact footprint and much greater height than any other building on campus.
Propelled to preserve greenspace while meeting the growing demand for on-campus housing, the building has a compact footprint and much greater height than any other building on campus. Strategically positioned to catalyze the new Campus Greenway strategy, the building massing shelters the pedestrian realm from rain and shades its transparent ground floor from sun. Other passive design strategies—including fixed sunshades and optimized fenestration—balance daylight, heating, and cooling. Complemented by energy-efficient HVAC and lighting systems, these strategies ensure optimal performance while minimizing energy inputs and carbon emissions.
Working with local Indigenous communities, the design team explored opportunities to recognize and preserve the inherited spirit of place and connect students to Indigenous histories and cultures. A swath of concrete is transformed into a stormwater detention feature, serving the project site and beyond. Trees removed were replaced at a ratio of 3:1, following a planting plan developed through research into native species and consultation with Elders.

The project incorporates materials with environmental product declarations (EPDs) and health product declarations (HPDs) to avoid introducing harmful substances. The team also specified low-emitting materials in terms of volatile organic compounds (VOCs). Further, even with the windows closed, student bedrooms receive 100% filtered outdoor air, resulting in superior air quality, and minimizing airborne contaminants.
To optimize access to daylight, window ratios are balanced to meet thermal performance targets, allowing for generous floor-toceiling windows in public areas. Enhanced thermal insulation also provides acoustic separation from exterior noise, and mechanical equipment noise is kept to a minimum.
Together, insulation, shading, and thermal bridge reduction contribute to radical energy efficiency, as do triple glazing and an overall tested airtightness of 0.22 ACH50—approximately 1/3 of the Passive House limit.
As a cornerstone of UVic’s Campus Plan renewal, Cheko’nien House focuses on student life and resident activities, nurturing a sense of belonging and connection within the campus core. With its innovative mix of uses, regenerative design initiatives, careful detailing of simple materials, and focus on enhancing the student experience, Cheko’nien House sets a new benchmark for student housing worldwide and underscores UVic’s commitment to a vibrant, sustainable community.
The glazed aluminum curtainwalls, exterior sun control devices, and interior aluminum framed storefronts and doors offers users abundant natural light and a visual connection to the outside. Cascadia Windows & Doors supplied the fixed and operable fibreglass windows from its Universal PH Series.
BIRD’S WING PASSIVHAUS DUPLEX +
Vancouver, BC
JURY COMMENT:
“In addition to achieving Passive House performance, this duplex addresses multiple aspects of social sustainability, such as affordability, demographic diversity and ageing in place. It doubles the density in this former single-family zone, while still respecting the form and scale of the surrounding buildings.“
1. The folding roof line, like the wing of a bird in flight, and a modern, minimalist design, demonstrate a commitment to sustainability and innovation. The metal roofing and siding is Vicwest Vic Elite Ribbed Profile.
Bird’s Wing Passivhaus Duplex + is a new housing typology that elegantly adjusts to the occupants’ needs for space and flexibility, without waste. The name “Bird’s Wing Passivhaus Duplex +” has several layers of meaning, describing the architecture, planning, and unique objectives of this custom duplex that includes two primary dwelling units as well as two flexible lock-off suites.
The project takes a soft density approach, with four households under its wing, yet keeping within the scale of its single-family neighbourhood. Adaptability is key, with units able to expand and contract for generational flexibility.
The project also addresses accessibility for ageing-inplace, and affordability with its two primary and two lock off units on a previously single-family lot.
The architecture of Bird’s Wing incorporates a folding roof line, like the wing of a bird in flight. The modern and minimalist design demonstrates a shared commitment to sustainability and innovation. Located in an established neighbourhood on Vancouver’s west side, Bird’s Wing is just two blocks from an active commercial street.
2. Bird’s Wing brings four households together, with communal outdoor living spaces for larger gatherings. Cascadia Windows & Doors supplied the fixed and operable fibreglass windows from its Universal PH Series.

With a Walkscore of 92 and Bikescore of 91 there is rarely a need to drive. However, both parking spaces are equipped with electric car chargers.
The design is rooted in nature. The result marries thermal efficiency with spatial efficiency in a perfect balance of design, space, and nature. The four comfortable, yet compact homes are nested within what appears to be a single-family home. Each is unique, bright, and connected to the outside through large operable windows on all sides.
Consistent with Passive House goals of efficiency and simplicity to avoid wasting energy, the design also avoids wasting space or materials. Every square inch is considered, impactful, and multi-functional. The planning is a creative three-dimensional puzzle of interlocking pieces. The suites bend and fold around each other to maximize efficiency and provide evocative volumes within strict zoning regulations.
4. The duplex interior connects to the exterior through strategically placed openings for ample daylight and cross-ventilation. nVent NUHEAT Mats provide radiant floor heating in the bathrooms and are stocked in standard sizes or can be custom made for a perfect fit. Ideal for sustainable projects, NUHEAT systems are 100% efficient, smart home compatible, ultra-low profile, and easily installed.

5. Consistent with Passive House goals of efficiency and simplicity to avoid wasting energy, the design also avoids wasting space or materials, with every square inch considered.
Despite the interior complexity, the footprint of the home is continuous from foundation to roof, and incorporates a single notch in plan, to create architectural interest while keeping the thermal envelope simple. Thermal bridges were all but eliminated by way of self-supporting decks that are independent structures, and over-framing roof eaves above the thermal envelope.
In Vancouver, where land comes at a premium, splitting the cost of land and construction between two families, while also creating income generating and sustainable rental suites, made the dream of building a low-carbon Passive House duplex a reality.
Bird’s Wing brings four households together, with communal outdoor living spaces for larger gatherings, while providing each with their own functional spaces within. The rental suites are within the Passive House thermal envelope, providing healthy and high-performance rental suites for the community and the owners with rental income and flexibility in how they use their homes.
Bird’s Wing achieves certified Passive House and net zero ready certification, with a design that combines simplicity of form, low-embodied carbon assemblies, and the efficient use of healthy materials. As such, it offers an inspiring example of building less but achieving more.

GABION HOUSE
JURY COMMENT:
“An exemplar in its suburban context, this project is notable for its many technical innovations. The use of rocks from the site to form its character defining gabion wall is one example of its thoughtful and creative use of durable, low impact materials. Space planning emphasizes functionality and flexibility.“
1. The back of the house facing south-west and nestled within rock outcrops.
The Gabion House is a single-family house for a retired visually impaired couple and has been designed to support aging in place. The building features flexible spaces that accommodate multi-generational family events and generous food production and canning facilities. The house is located in a rural community of small farms and woodland parks close to Victoria on southern Vancouver Island. The site supported the owners’ desire to design for both the present and the future.
Their design goals for the project included:
• enable aging in place and appropriate for the sight impaired
• withstand seismic events, extreme weather and food scarcity
• support its local ecosystem
• be made from non-toxic materials with a low carbon footprint
• be efficient to operate and maintain, and
• last for generations.

In response to these goals, the Gabion House is Passive House certified and features a post-disaster structural system. The house is self-sustaining, as it can generate its own power and operate with its own water supply and wastewater management system. Battery backup and food and water storage can provide resilience over extended periods.
Another driver of design was that the site lies within a Garry Oak ecosystem, unique to southwestern British Columbia, and among the rarest in the province. Preservation and celebration of this ecosystem, including its many rocky outcrops, were priorities throughout the project.
The overall site design strategy was to work with the existing natural elements, thereby supporting the existing ecosystem. The house is nestled within these outcrops and cantilevers over the lower meadows to the south. One formidable Garry Oak specimen became the focus of the design, with all outdoor living spaces oriented around the tree.
Local rocks from the site were used in the gabion walls for which the house is named. These walls start within the building and extend out into the site. The principal structural material is wood, which is used for truss floors, roof systems, and a double-wall system. These elements were filled with cellulose to minimize the carbon footprint of the building. The exterior wall assemblies are 635mm thick, achieving approximately R80.
As a certified Passive House building, the Gabion House uses a heat recovery ventilation system to provide fresh air throughout the house at all times. The highly insulated and tightly sealed building envelope, with strategically placed glazing for passive solar gains in winter, together reduce the operating energy demand to a level that can be met with a small PV array.

This makes the house a net zero energy building. The building is not connected to municipal water. The only water used in the building is drawn from the site and is well within annual rain levels. Four large storage containers store collected rainwater for irrigation and food production. All wastewater is managed on-site.
With net zero energy, net zero water, waste treatment on site and a palette of low carbon, natural materials, the design team is also seeking partial (petal) certification under the Living Building Challenge.

JURY COMMENT:
“This adaptive reuse of a 1950s commercial building is notable for its creative and comprehensive approach. Beyond the improvements in performance, the innovative repurposing of materials, such as tiles into countertops and existing studs into wood screens, make for a very elegant transformation.“
The retrofit brings new life to this modest, long time vacant commercial building. The metal cladding is Vicwest AD150 series panels in charcoal colour. Winnipeg-based Duxton Windows & Doors supplied provided fixed, tilt & turn, and slider sash fiberglass windows and series 458 doors.
2. Before the renovation.
3. and 4. Wood studs were salvaged and reused on the exterior front facade as a green wall trellis and as a slat system at the interior stair opening.
The extensive retrofit of 107 Marion Street in Winnipeg showcases the adaptive reuse of a longtime vacant commercial building. The 300 sq.m building constructed in the 1950s was originally a fruit market with a residence above and is now home to an architectural office and photo studio space.
The ambition for this project was to be a showcase for sustainable construction, taking a “re-think everything” approach: developing creative ways to reuse, re-purposing and integrating salvaged materials from other sources into the project, reducing construction waste through the owners per¬forming the deconstruction work, delivering salvaged material to recycling depots, and donating any surplus for re-use and up-cycling.

Extensive material salvaging and recycling from all components of the existing building was considered from the outset. All usable fixtures, doors, and millwork were donated to Habitat for Humanity, and the demolition was approached as a deconstruction process to preserve materials.
For example, the existing wall partitions were dismantled, with the wood studs set aside for reuse in the new design, over 50 lbs. of nails were removed and recycled, and the plaster sent to a local recycling facility for use as fill in road construction.
The wood studs were reused as a slat system at the interior stair opening and on the exterior front facade of the building as a green wall trellis. The second storey had hardwood flooring throughout and in locations where wall partitions were removed, was infilled with hardwood salvaged from another local project.
The original main floor finish was a 1950s local terrazzolike product called Trevi Tile, which was fully restored. Additional Trevi Tile was uncovered on part of the front facade, and re-purposed as risers on the second-floor staircase. With crafty expertise, the mechanical contractor upcycled a 1950s duct into a one-of-a-kind mailbox.
The Habitat Re-Store became a source for second-hand products such as light fixtures, shower pan, and sinks, to incorporate into the design. The original stair treads to the second floor were carefully dismantled, refinished, and modified to become the stair to the lower level. The shower tiles were discontinued samples from previous projects. Approximately 30% of construction debris was diverted from the landfill.
While the creative reuse of materials was extensive and character-defining for the project, the design approach also emphasized access to natural light and ventilation, visual connection to the street and surrounding community, water conservation, and rainwater harvesting for irrigation. The thermal performance of the enclosure was improved by adding extra insulation to the roof and walls.
Having chosen to disconnect the building from the natural gas supply, air source heat pumps were installed, providing cooling and heating via a DX coil in each furnace. When the heat pumps reach their cold temperature limit, electric resistance coils in each furnace supplement the heating, with electric base board heaters on ultra-cold days. The project was the first to enroll successfully in Efficiency Manitoba’s Commercial Deep Energy Retrofit Program, achieving an annual energy intensity of 128 kWh/m2 per year: a 36.4% improvement over the reference building.

HEIMAKLETTUR HOUSE
Langley, BC
JURY COMMENT:
“This small house is a great example of how doing more with less is key to sustainability. It is appropriately sited, well designed, well detailed, well crafted and thoughtful in its execution. It is notable for its modesty and simplicity, yet the interior has a generous sense of space and light.“
1. The house form references contemporary Nordic dwellings featuring pitched roofs, lean-to additions, wood framing, and contrasting cladding.
This house was designed for an ambitious family on a five-acre property within the Agricultural Land Reserve (ALR) in the Fraser Valley community of Langley. The clients’ initial vision for the project included the goals of living smaller and more closely to the land and ultimately growing their own food.
Heimaklettur (home rock) is named after their father’s hometown of Vestmannaeyjar in Iceland. The house form references contemporary Nordic dwellings featuring pitched roofs, lean-to additions, traditional wood framing, and contrasting cladding.
The design responds to existing site characteristics and bioclimatic conditions, such as solar orientation, shade from existing trees and the prevailing wind, while placing the building on the previously disturbed area of the site and utilizing the existing septic system.
2. The building enclosure is highly insulated, with triple-glazed windows in fibreglass frames and minimal thermal bridging. The various siding profiles are western red cedar.
2
The house respects the required 30m setback from the nearby creek and is set above the flood datum of 7.95m geodetic. A simple plan defines the overall form, articulating a “living gable” and a “sleeping gable”, and incorporating a change in level of 450mm with a children’s play attic above. The mudroom plays a key role in the plan, filtering the messy activity of everyday life on a rural property, while also differentiating the south gable form of the house. The narrow plan offers ample daylight, views and cross ventilation throughout the home.
The building enclosure is highly insulated, with triple-glazed windows in fibreglass frames and minimal thermal bridging. Heating is provided by a high efficiency HRV forced air system that maintains a ventilation rate of 1.0 air changes per hour throughout. The project achieved Step 5 of the BC Energy Step Code, and an Energuide rating of 47.

The gables are oriented north/south with view and ventilation windows on all sides. The site is forested along its east edge and southeast corner with reduced direct daylight on the home until midafternoon for much of the year. Deciduous trees have been planted along the west face to limit late afternoon heat gain. A high-level fan redistributes warm air that has stratified within the vaulted living space. The entire site was kept permeable and roof rainwater is captured with controlled release to the wetland area to the north.
and 5. The interior has a generous sense of space and light. Fixtures and finishes are natural with limited VOCs or allergens. Cascadia Windows & Doors supplied its fixed and operable fibreglass windows.
The project maintains a strong connection to the site, with strategically placed windows and a direct connection to nature and the outdoors from the living spaces. The home is primarily built of natural and locally-sourced material – largely wood and wood products. The structure is wood frame on an exposed concrete slab on grade with a polished finish. The various siding profiles are western red cedar, while the roof is standing seam metal.
Internally, fixtures and finishes are natural and easy to clean with limited VOCs or allergens. These include painted gypsum wall board, pine board and clear finished maple plywood millwork. In keeping with the simple aesthetic, furniture is functionally minimal.
With its careful siting, simplicity of form, economy of space, and robust material palette, Heimaklettur House sets an inspiring example for other single-family residences to follow.

WINDERMERE FIRE STATION 31
Edmonton, AB
JURY COMMENT:
“A fine example of a building in which the form is driven by its performance targets, the sustainability strategies required, and the technologies employed to implement them. The result is simple and elegant, a radical and refreshing departure from the traditional architectural responses to this typology.“
Windermere’s Fire Station 31 is both symbolic and functional, extending the role of this building type as a trusted civic presence and anchor for the neighbourhood. The project site was unbuilt and unremarkable – essentially a blank slate. The challenge was to design an expressive structure that would foster community pride while integrating advanced environmental technology.
The City of Edmonton requested a highly sustainable project that would generate on-site renewable energy equal to 100% of total building energy needs. The facility was also required to have an energy performance 40% more efficient than NECB 2011, reduce GHG emissions by at least 40% relative to the baseline, and operate at 80 kwh/m2/year for heating needs.

In response, the building re-imagines the traditional fire station design by replacing the nowredundant hose and bell tower form with a gently curving, south-facing roof adorned with photovoltaic panels. Further sustainable strategies include optimal southern orientation for natural light, geothermal systems, well insulated and highperformance windows, and quick-closing apparatus bay doors to minimize heat loss. Windemere Fire Station 31 underscores a shared commitment between the City of Edmonton and the design team, to sustainable public infrastructure and a healthier future for citizens.
1.The City of Edmonton requested a highly sustainable project that would generate on-site renewable energy equal to 100% of total building energy needs.
2. The facility has significantly fewer windows than the average building, and uses bi-folding and quick-closing apparatus bay doors to restrict heat loss from typical daily use
The site of Fire Station 31 is south of a local public school and low-rise apartment buildings, and north of a new commercial centre. The station is well located for emergency response and to meet the functional requirements of Edmonton’s Fire Rescue Services. The building is a single-storey, three-bay design that provides full fire fighting services.
Integration of passive systems is optimized by the southern orientation of the building, which maximizes natural daylighting as well as creating maximum efficiency for the photovoltaic panels on the south- facing roof. The facility also has significantly fewer windows than the average building to reduce heat loss. Solar panels, geothermal systems and bi-folding and quick-closing apparatus bay doors which restrict heat loss from typical use, are active systems which are employed to enhance the overall performance of the building.
The challenge of this project was to integrate the various technical requirements of a fire station with the technical requirements of a netzero building, while providing a contemporary design that responds to the historic iconography of a fire station.
3.The traditional fire hall hose and bell tower form - now redundant - are reimagined with a gently curving, south-facing roof.
4.The roof is outfitted with an extensive array of photo voltaic panels.
5.The apparatus bay interior is bright white to maximize the feeling of natural light, promoting a healthier work environment.
6. Full-height corridor glazing draws daylight from an exterior courtyard to the central fitness room.
A high-performance envelope, energy recovery and a geothermal heating and cooling system achieved the required 40% reduction in energy demand, with the on-site solar PV energy production offsetting the remaining demand, making the fire station a carbon-neutral facility.
The Thermal Energy Demand Intensity (TEDI) of 71.5 kWh/m2 indicates that the efficiency of the building and its systems is substantial relative to comparable buildings. At Windermere, where the large apparatus doors are opened and closed approximately 4,000 times per year, the challenge of addressing the large volume of heating loss or gain (winter or summer) was significant.
This challenge was successfully addressed by focusing on door speed, the extent and type of glazing, the thermal performance of walls, slab and roof, and the eradication of thermal bridging. Together, these resulted in a reduction in Greenhouse Gas Emissions of 99%.

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
