The submissions were characterized by their holistic approach to sustainable design, often embracing the ambitions of multiple third party programs, such as: Passive House; the WELL Building Standard; Net Zero Energy; Net Zero Carbon and the Living Building Challenge.
Each of the winners was exemplary in this regard: Both the Skeena Residence at UBC Okanagan in Kelowna and the North End Landing & James North Baptist Church in Hamilton, achieve Passive House energy performance while creating stimulating and attractive interior environments. On a related theme, the University of Victoria district energy Plant provides a rare example of an industrial facility with an ‘education through transparency’ program and an attractive interior working environment Occupant wellbeing was addressed both psychologically and physiologically in the BNP Paribas office in Montréal and the Indigenous Ecological Knowledge project implemented on First Nations’ reserves in northern Saskatchewan.

Commercial/Industrial (Large) Award (sponsored by Mitsubishi Electric Sales Canada Inc.) BPD Quadrangle
80 ATLANTIC Toronto, ON Jury Comment In a market where commercial buildings of this size and type were once common, this project sends a signal that mass wood construction is once again a viable and highly desirable option. The warmth of the exposed wood and high quality of interior daylighting contribute to a beautiful working environment. With its glass exterior, the building makes a striking and poignant complement to its historic Brick and beam neighbor, reinforcing the idea that both aesthetically and technically, mass wood can be part of a more sustainable future.

East-West building cross-section 3

Typical parapet along East + North + West
A south-facing curtain wall mitigates the building’s mass and scale, while showcasing the mass timber interiors to passersby. Rather than being exposed within the occupied spaces, HVAC ducts, integrated into the floor plenum, keep the air moving and temperatures comfortable. The electrical and telecommunications systems are also below the floor, resulting in a highly adaptable and uncluttered space. Unobscured by ducts or bulkheads, the natural wood columns and ceilings are on display throughout. Building users have more control over their environment than in a typical office setting, thanks to operable windows which are easily accessible to 30% of occupants and interior shading control through user operated blinds. Significant energy savings stem from an energy recovery ventilator with 88% sensible recovery serving the rooftop units and condensing boilers with a thermal seasonal efficiency of 90%. High-performance LED lighting and occupancy sensors reduce the energy required to light the space by more than 50% compared to the code referenced standard.

3. The buff-coloured surface of the Ceramitex® rainscreen and the scale of the punched windows honour the industrial brick vernacular of the area. The 19,455 sq ft. of thin sintered ceramic is manufactured with the fiberglass-reinforced mesh backing that is adhered to the Elemex® Unity® Attachment Technology, making it a durable and versatile choice. 4. The vegetated roof controls run-off and serves as a pollinator garden. 5. Recent changes to the Ontario Building Code, allowing for commercial wood buildings up to six storeys, motivated the team to use mass timber post and beam for an open warehouse look that optimizes layout flexibility. 6. HVAC ducts and electrical/telecommunications systems are integrated into the floor plenum resulting in a highly adaptable and uncluttered space.
80 Atlantic also features the first vegetated roof on a mass timber commercial building in Toronto, setting another precedent for this market sector. The vegetated roof is a combination of intensive and semi-intensive species, with taller grasses around the edges. Site landscaping includes 100% native tree species, planted in Silva Cells, and at least 50% native and drought tolerant plants. Rainwater is retained and reused for landscaping. From its inception, 80 Atlantic attracted the attention of design and construction professionals as well as the general public. The design team responded by creating educational opportunities, including the construction and testing of fullscale assemblies for students at the Carpenters Union, and frequent open house events for the construction industry and public alike.

With proven performance in winter conditions, it also provides LEED credit eligibility for regional manufacturing. 3. A mix of cladding was used on the project. CBC Specialty Metals supplied through Bothwell-Accurate Co. Inc the VMZINC® ANTHRAZINC® STRAT Interlocking Panels, having expected lifespan of over 100 years. Quarried in Ontario, Adair natural limestone by Arriscraft, used around the base of the building, is unique in the industry offering unparalleled distinction and longevity for commercial projects. 4.

Jury Comments: Not only does Passive House certification take this building beyond Code in terms of energy performance; it achieves this while still addressing issues of context and community. The relationship to its surroundings is carefully considered, as is the design an organization of its common spaces. Making successive cohorts of students aware of the superior quality of a Passive House environment – and so raising their expectations, may be the most significant contribution of this project. 3

This new Passive House certified residence accommodates 220 students within five floors of light wood frame construction, above a concrete ground floor that contains common areas, amenity and service spaces. The building completes an ensemble of residence buildings encircling the central green space on campus – known as Commons Field. The five identical residential floors include shared bathrooms flanked by two bedrooms. This layout allows space for quiet study when required. Additionally, each floor contains both a study lounge and a house lounge with views of the surrounding mountains, the latter equipped with a kitchenette, dining table and couches. Locating these spaces at opposite ends of the floor ensures that quiet study is not interrupted by noise from the social home lounge. The first level includes a large laundry room adjacent to the student lounge. Separated by a glass wall, the relationship between the two spaces encourages chance meetings and spontaneous gatherings. Moreover, the transparency offers passive surveillance, or visibility that promotes a sense of security.

The Passive House goal of minimal energy use for heating and cooling informed many design choices. Given that irregular forms with multiple indentations and corners, or projections such as steps, overhangs, or canopies create challenges for insulation, airtightness and the elimination of thermal bridging, a simple and efficient rectilinear volume performs best. This limits aesthetic parameters to material, colour, pattern, and texture. The simpler the building, the more important material choices and detailing become. The exterior is clad in a combination of lightly-coloured fibre cement and darker metal panels. A feeling of depth is created by bringing the fibre cement panels forward of the metal, emphasizing the depth of the window reveals and providing articulation without adding complexity. The design process required accelerated decisionmaking and involved more work during schematic design than for traditional projects. For example, understanding thermal bridging implications and other energy-loss considerations necessitated the early involvement of a building envelope specialist and the front-loading of assembly and junction detailing.
6 5 Detailing of the mechanical systems early on was also vital to maintaining the schedule and budget. For example, Passive House performance requires mechanical service pipes to have thicker insulation than for a conventional building and collaboration between disciplines was necessary to achieve this within typical assembly dimensions. It was also possible to adjust other building components to achieve the energy goals. The density of occupants in a student residence necessarily presents further challenges. With a student population comes a far greater number of fridges, hair dryers, and computers per square metre than a typical mid-range residential building. These appliances create a significant plug load, or electrical draw. Similarly, the number and frequency of showers taken and loads of laundry washed increases humidity and mandates the careful calibration of air change rates to avoid condensation and mould. To minimize greenhouse gas emissions, the building is not connected to the natural gas supply. Instead, it is a standalone electric-based system and utilizes electric heat pumps for heating and cooling. The result is a greenhouse gas intensity of just 0.66 kgCO2eq/m2 per year.

The two-storey exposed Dowel-Laminated Timber (DLT) wall, floor and roof structure is supported on a western red cedar pole-and-beam frame, this use of local, sustainably harvested wood contributing to a net construction carbon footprint of negative 194 metric tonnes. With reversible screwed connections and no adhesives, the building is also designed to be completely demountable at the end of its service life. All operating energy requirements are met using hydroelectric power. Since the site is centered on the Pacific Flyway where sea and sand flats provide food and habitat for millions of migratory birds, preservation and enhancement of natural ecosystems was a key driver of design. Glazing is bird-friendly. Tiny hummingbirds on a 2x4 grid provide child-sized reminders of connectedness to the natural world and the need to preserve biodiversity.

Native plantings offer feeding and nesting opportunities at different times of the year. Red, orange, and purple native wildflowers provide nectar, seeds and autumn fruit. The site retains native grasses and trees that provide cover for nesting Western sandpipers and insects to supplement their mollusc-based diet.

We believe wood is the most natural and healthy product to build with. We have 25 years experience in mass timber, having worked on development of DLT in Europe in the 1990’s. We are now proud to be pioneering both stacked and cross laminated DLT in Canada. We design, engineer, manufacture and install Wood100® DLT, a 100% wood, no glue DLT. Architects, engineers and builders are realising the potential of Wood100® DLT as a healthy, sustainable and energy efficient building product.
Wood100® DLT is Truly Sustainable Our 100% wood DLT contains no glues or other chemicals, making it 100% recyclable. It can be disassembled and reused or composted at the end of its life. The energy consumption during manufacture is roughly 3.5 times lower than other mass timber products, significantly lowering product emissions.
Wood100® DLT is Energy Efficient Our cross laminated Wood100® DLT product holds records for heat insulation in structural material and therefore minimal operating costs. Tests of 3 wall systems with the same R-value showed the supremacy of cross laminated DLT. An average 100% wood DLT home needs 1/3 of the heating system compared to traditional framed homes with the same R-value. It’s like having air conditioning and heating systems with zero energy consumption.
Wood100® DLT is Healthy WIth no off-gassing from glues or contamination from chemicals, Wood100® DLT offers a significantly healthier indoor environment, particularly for those with allergies and hypersensitivity. 100% wood DLT regulates the indoor climate much better because moisture can be transferred freely between the entire wall system. Radium Community Centre and Library is a past winner of the Canadian Green Building Award. International Timberframes was excited to collaborate with Urban Arts Architecture and other building partners on this project, one of the first in Canada to use DLT. We prefabricated and installed the Wood100® DLT variegated roof panels, integrating the design with other wood elements in the building. Collaborating with architects on detail solutions across the design process guarantees quality control from start to finish.

The new air space required tempering to ensure a dry and temperature-controlled environment, without condensation or freezing. The minimum air temperature is set to 5°C. Great efforts were made to limit the energy consumption of this newly added space. The inter-disciplinary team went through a series of tests and adjustments to ensure perfect adaptation to the building’s unique shape. This involved computer simulations and computational fluid dynamic (CFD) analysis, as well as energy simulations to balance the air temperature throughout the void.

The first project in Canada to be certified under Version 2 of the WELL Building Standard, the new headquarters for BNP Paribas , the French international banking group, exemplifies current best practice in employee-centred office design. To alleviate overcrowding and bring its 140 staff under one roof, the company chose to relocate and refit 140,000 sq.ft. of space spread over six floors of an existing 1970s office building.

From the outset, the aim was to achieve WELL Building certification and to create a dynamic work environment that would promote social interaction and collaboration as well as the health and comfort of occupants. The challenge was to meet the client’s desire for a fluid, flexible, non-Cartesian layout of space within the physical constraints of the existing structure, which included working with the two feet by four feet ceiling grid. This led to the development of a workplace where the main open spaces are divided into several zones alternating those intended for work, collaboration and rest. Work areas are not assigned; employees can settle wherever they want in the building, or even telecommute. The workstations are arranged at the perimeter, so employees benefit from maximum natural light. Common spaces are located at the core of the building and include glazed meeting rooms, changing rooms, and sanitary facilities. To energize the occupied spaces, the strategy was to create what the design team refers to as “organized chaos” through the choice and arrangement of lighting and office furniture. Artificial lighting integrates a variety of high-performance luminaires, adapted to the functions of the different areas with dynamism in mind. As required by WELL, the lighting is designed not to disrupt the occupants‘ circadian rhythms. The office furniture system includes a spine that integrates all the wiring required. Workstations can be moved along this spine in either direction to modify the space and employees can alternate between sitting and standing positions. Low VOC materials minimize airborne pollutants and 20 living walls help purify the air while enhancing the human biophilic response.

These prototypes are the vanguard of 40 laneway and infill homes proposed for the Huron Sussex Neighbourhood, a historic precinct adjacent to the University of Toronto’s downtown campus. The project advances urban intensification in a location well served by public transit and existing municipal infrastructure, while revitalizing and helping to sustain its immediate heritage context. Mandated to deliver affordable, sustainable housing for family living and co-habitation, the project utilizes a prefabrication approach to reduce community impacts during construction and enhance performance outcomes. The three prototypes include: 3 bedroom + 2 study (2,100 gross sq.ft.), 2 bedroom + study, (1,100 gross sq.ft.), and 1 bedroom + study, (900 gross sq.ft.). Sympathetic to scale, massing, and neighbourhood context, the prototypes provide ‘accessibility through proximity’ and are clustered to create a shared outdoor courtyard and to initiate a ‘Living Laneway’ concept with homes accessed from the lane.

This eliminates the need for mechanical cooling. This system was realized due to the demolition of a derelict house – its basement provided the opportunity to install the system prior to backfilling and redevelopment of the site as a playground for the neighbouring daycare.

• The use of prefabrication reduced the effects of noise, construction traffic and on-street parking typically associated with conventional site construction. Prefabrication also improved quality, reduced cost and construction time (by two months), and confirmed the replicability of these prototypes. It also contributed to tighter construction, improving air tightness and thermal performance. • The pre-manufactured, frost-protected slab-on-grade foundation enabled a single concrete pour, rather than the more typical three (i.e. footings, frost wall and slab). This reduced the volume of concrete and associated excavation required. These first-generation prototypes have demonstrated that prefabricated high-performance, low-impact construction can be less complicated and delivered without a cost premium compared to conventional construction, making this type of living accessible to more people.

envelop yourself in daylight... photo by Alex Upton
Today’s LEDs may last up to 50,000 hours, but then again, Kalwall will be harvesting sunlight into museum-quality daylighting™ without using any energy for a lot longer than that. The fact that it also filters out most UV and IR wavelengths, while insulating more like a roof than a skylight, is just a nice bonus. ®

The building is designed to maximize openness and transparency, welcoming the community through its generous entrance, windows and skylights. An atrium cuts through the centre of the church facilities, its large skylights flooding the interior with natural light. The program includes a full-size gymnasium/auditorium, together with expansive multipurpose spaces that accommodate a variety of activities, events and gatherings for children, youth, and adults. North End Landing is one of the few fully accessible community buildings in the area. The integration of affordable housing into this diverse, community-focused program helps alleviate any associated stigma. This integration of program is part of a broader intention to promote health, wellness, and belonging. The structure is steel and concrete, both materials locally produced in Hamilton, and natural wood finishes are used in the church and gathering areas. Together with the ample daylight, these create a biophilic environment promoting a sense of calm and positive emotions. Food is central to human gatherings, and the church kitchen and hospitality area facilitate easy and regular gatherings of neighbours, which may spill directly out onto a patio forecourt. In addition to community gatherings, sports and physical activities are also central to the ministry model of the church, so the full-size gymnasium is designed to host a wide variety of sports and community activities. Indwell’s holistic approach to supportive housing helps ensure tenants can achieve their best potential to participate in the broader community, regardless of income, age or abilities.
