Residential (Large) Award – 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.”

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.

Institutional (Small) Award – 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 now-redundant 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 high-performance 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.

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.

Residential (Small) Award – 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.“

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.

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.

Residential (Small) Award – 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.“

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-in-place, 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.

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.

Technical Award – MINISTRY OF CHILDREN & FAMILY DEVELOPMENT, Williams Lake, BC 

Jury Comment: “This project takes an underutilized, poor performing and discarded single-storey retail building and transforms it with a variety of technical interventions that make it net-zero, thus greatly extending its service life. Inside, the plain box has been enlivened with light, colour and cultural references.“

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 single-storey 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.

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.
