Welcome to our annual issue showcasing the winners of the 2020 Canadian Green Building Awards, selected by a jury that included Shelley Craig, Principal at Urban Arts Architecture in Vancouver, Claude Bourbeau, Associate Principal at Provencher Roy Architects in Montreal, and Alan Murphy, Principal at Green Reason Inc. in Toronto. The nine winners reflect the diversity of this yearâ&#x20AC;&#x2122;s competition and the quality of work now being realized in communities large and small across the country.

Three certified projects illustrate how the Passive House program has extended its reach over the past five years: The Charter Telecom HQ, a leading-edge commercial office building in Langford, BC; the Westbay Passive House, a beautiful, light-filled residence on the waterfront in West Vancouver; and the Reach Guest House, the remarkable rehabilitation of a 19th century farmhouse in Prince Edward County, ON into an ultra-low energy contemporary residence. The private sector was also well represented outside of the Passive House program, with three exemplary projects from Ontario: The Rehabilitation and conversion of the 1930s Bata Shoe Factory into a mixed-use building for the community of Batawa; a similar treatment of Cours Bayview Yards, a 1940s municipal building in a former industrial area of Ottawa; and the Sifton Centre, the first structure in a planned 30-hectare net zero mixed-use development in London. Always a source of high quality, high-performance building, particularly in the areas of post-secondary education and supportive housing, the public sector was represented this year by: The Northern Lights College Trades and technology building in Fort St. John, BC, that provides an uplifting environment for students while achieving a remarkable level of energy performance in a harsh northern climate; the Rob and Cheryl McEwen Graduate Studies and Research Building at York University, which combines climate adapted design solutions with a focus on student wellbeing; and Covenant House Vancouver, an exemplar of best practice in the provision of support services for youth at risk. We extend our thanks to our jury (see page 10) for their skill, professionalism, and sincerity in reviewing all of the submitted projects. Thank you, too, to all those who submitted entries this year, many of which we will be featuring in upcoming issues of SABMag or in the regional CaGBC FOCUS publications. And, we especially thank our national sponsors, Masonite Architectural and the Canadian Precast Prestressed Concrete Institute, along with our category sponsors noted below. Without their support we would not be able to mount the annual SABMag Awards program.

news INTRODUCING A NEW WAY TO CONNECT WITH THE RAIC Tanner Morton Following over a year in development, RAIC Connects launched on October 5, 2020 –in honour of World Architecture Day– to further connect members and foster meaningful conversations within the profession. RAIC Connects is a new online community platform accessible to all members of the RAIC, as well as non-members that are active in committees and task forces. The platform is a forum-based website with multiple functionalities including announcements, email notifications, events, and file sharing. Since it was launched, a plethora of discussion posts have explored topics including procurement trends, design responses to COVID restrictions, the licensing process in Canada, working from home during the pandemic for architects, and questions on mass timber, among others. A key feature of the connects platform, and one that has proved invaluable so far, is the development of separate communities around shared topics and points of interest. Some, like the forums for committees, were established at the outset—so that members of these groups can come together and plan their activities and initiatives regardless of their physical location at the time. Other communities were cultivated through shared interests, specializations, and areas of study in the industry. It’s important for users to feel empowered, to use their voice and, as the name of the platform suggests, build lasting, meaningful connections that will benefit themselves—as well as extend the conversation in the greater profession. Having a dedicated space to nurture conversation in the architectural profession will be a benefit for Canadian architecture in both our current moment and what lies ahead in the future. Creating connections and fostering a stronger sense of community is vital for the health of the profession in the years ahead. The RAIC is working hard to make the cultural conversation on architecture as dynamic and engaging as the profession itself.

1600 Carling Avenue, Ottawa.

MANULIFE GLOBAL HEAD OFFICE Our commitment to sustainability begins at home with our Global Headquarters located in Toronto. Already BOMA Best certified, our headquarters achieved LEED Gold and certified our North Tower Fitwel in 2019. Following the success of our LEED program, we developed an internal Fitwel certification guide for our property teams. Currently, over 80% of our portfolio, or 48 million square feet, is certified to a green building standard. We continue to target properties for LEED and other sustainable building certifications.

1600 CARLING In January 2019, 1600 Carling Avenue made history as the first building in Canada to become certified under the LEED version 4.1 for building Operations and Maintenance. With v4.1, LEED has streamlined the certification process by focusing on five data-driven performance outcomes: transportation, water, energy, waste and human experience. Drawing on lessons learned from 1600 Carling, we successfully certified an additional 15 buildings. Our dedication to providing sustainable spaces for our tenants led to the development of our internal sustainable building standards program in 2017. The program provides visibility into our buildingsâ&#x20AC;&#x2122; performance and allows property teams to collaborate with our tenants on creating sustainable spaces.

news CHBA QUALIFIES FIRST HOME WITH NET ZERO ENERGY RENOVATION LABEL The Canadian Home Builders’ Association (CHBA) has awarded the first Net Zero Energy home renovation label for a house in Calgary under its recently launched Net Zero Energy Renovation Labelling Program Pilot. The house, renovated by Solar Homes Inc. of Calgary, was originally built in 1985 and now has achieved a net zero energy rating. Net Zero Energy (NZE) homes produce at least as much energy as they consume on an annual basis. While there have been almost 400 NZE homes built and labelled in Canada under CHBA’s program since 2016, achieving net zero energy through renovations is a new frontier with many additional challenges, but will vastly improve the performance of Canada’s existing housing stock. The renovation focused on retrofitting the exterior of the home, which minimizes disruption to occupants and results in an extremely comfortable home. In addition to decreasing the home’s energy bills – estimated to be around $2500 lower than before – the renovation has resulted in completely netting out the home’s GHGs emissions, which was previously 14 tonnes per year.

THE ARCHITEK GROUP ADDS NEW TEAM MEMBER FOR EASTERN CANADA EXPANSION The Architek Group has welcomed Ms. Sandie Anctil as its Architectural Specifications and Business Development Manager. A veteran in the AED industry, she will apply her expertise in architectural specification and support to Architek Sustainable, as well as Rope and Cable Canada, and looks forward to working with municipal planners, developers, architects, and contractors in developing well-designed, cost effective solutions for projects across Canada. 1-888-317-9226 or info@architek.com.

MAJOR COMPANIES AND RETAILERS JOIN BASF’S RECICHAIN PILOT TO IMPROVE CIRCULAR ECONOMY AND TRACEABILITY OF RECYCLED PLASTICS IN CANADA

BASF, CSSA, Layfield, London Drugs, Merlin Plastics, NOVA Chemicals, Recycle BC, Return-It, Save on Foods and V.I.P. Soap have joined forces to respond to one of the most pressing environmental challenges – plastic waste. Supported by reciChain, these companies aim to strengthen the circular supply chain, extend the lifecycle of plastics, incentivize recycling, reduce waste and enhance resource efficiency in Canada. reciChain combines the power of SMX’s blockchain solution with their physical marker that enables the secured sharing of transactional data while improving the sorting, tracing and monitoring of plastics throughout the value chain. Implementing these technologies, value chain actors would conceivably be able to generate tokens or ‘plastics credits’, which would in turn increase in value as plastics go through additional loops. These credits could then be used to incentivize producers to design for recyclability, thus enhancing circular economy. For the pilot project in Vancouver, BASF is also partnering with Deloitte as a strategic advisor. The reciChain plastic value chain actors, on their part, are offering in-kind contributions to enable the feasibility of the pilot such as plastic material, testing, and technical expertise. This track and trace technology used in reciChain marks plastic products with a unique “chemical barcode” and connects them to a digital twin. Both rigid and flexible plastic products will be used during the pilot to test the feasibility of the marker technology in the reverse logistics process. The pilot will allow users to access and verify information associated with the production of the material, supporting producers' recycled content targets and retailers' plastic waste diversion targets and further closing the plastic loop. The pilot will also include a parallel testing of BASF’s trinamiX Near-Infrared Spectroscopy Solution, a hand-held scanner that detects and documents the composition of plastic material. The project is being validated in British Columbia’s local supply chain. BASF’s vision is to expand reciChain to a nation-wide solution in order to position Canada as a leading country in recycling and recovery of plastics. To learn more about reciChain and potential partnership opportunities, visit www.basf.ca/reciChain.

SIFTON CENTER London, ON

Diamond Schmitt Architects Commercial/Industrial [Large] Award Jury: This is a really great case study building for commercial developers. The clever articulation of the form to reinforce the street at ground level, and to optimize solar exposure above, combined with a low window-to-wall ratio and the attention paid to indoor environmental quality are all strategies that are both affordable and effective. The abundant natural light, communal spaces, and a biofilter living wall to clean the air,

all enhance occupant wellbeing.

3 Artificial lighting is LED throughout and connected to both daylight and occupancy sensors and the building automation system. These systems ensure that artificial lighting is used, in the first instance, to enhance natural lighting; that space lighting is

turned off when individual spaces are unoccupied and the global building lighting is operable in concert with planned operating

times. Taken together, these systems result in a projected total energy consumption of the lighting system of 27.4 KWhr/m2/year. The most important contribution to reduced energy consump-

tion is made by the passive design approach noted above. Active systems were then added to supplement the passive strategies.

Ventilation air is provided by a 100% outside air heat recovery

air handling unit, which pre-heats and cools the outside air from the building exhaust air stream through a heat wheel. Ventilation air is delivered on an as needed basis through the monitoring of

zone CO2 levels throughout. This minimizes the energy required to treat outside air. The peak design flow for the outside air is one air change per hour. The treated air is delivered to the Variable Refrigerant Flow

(VRF) distribution system. The VRF system is an electrically driven, three-pipe refrigerant-based, dynamic energy recovery and sharing system. Heat and cooling generated in a central compressor plant is delivered to terminal units in various zones on an â&#x20AC;&#x153;as-neededâ&#x20AC;? basis through supply and return piping.

2. The Sifton Centre uses low-VOC materials and provides ample social areas for employees. 3. Glazing accounts for less than 30% of the overall envelope area and is comprised of a mixture of triple-glazed vision windows, light-diffusing insulated slab glazing and insulated spandrel glazing. 4. The two-storey living biofilter wall in the ground-floor lobby enhances air quality in the common spaces by filtering and humidifying the air. The heating and cooling system uses Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric Sales Canada.

The project’s form synthesizes weather-responsive design with urban design resolution of the highly-constrained site. An urbane block floating above a pedestrian colonnade lines the main campus entryway. The block splits where the folded glass skin of the atrium invites interior views. Such folds are used to “twist” the building from the street grid to reorient its south facade for optimal solar exposure, daylighting, and shade design. A curving single-storey wing of classrooms cradles a courtyard, buffering it from traffic. South- and west-facing glazing with Inline Fiberglass windows is shaded in summer by solar awnings and louvered shading devices. The building is conceived as a terrain for the exchange of ideas. That is expressed in its three-dimensional section and architectonic form. Its materialization melds architecture and engineering. The three-storey atrium is its performative heart: a theatrical place for gathering and programmed events, a welcoming movement hub and an air-distribution collector for the unique hybrid natural-and-active ventilation system. This social focus, together with the climateresponsive design of the building manifests Schulich’s commitment to social engagement and sustainability. The project is also sited within a three-minute walk of the York University subway station, meaning that no additional on-site parking was required. Instead, numerous bike parking rings were installed near the entrances to the building. The project is targeting LEED Gold certification and is also equipped with the energy infrastructure required to achieve net zero energy in the future, pending the addition of onsite photovoltaic panels.

This three-storey office building, located in Greater Victoria, aims to be the first commercial office in North America to achieve Passive House Certification. It is also ambitious in its use of locally-sourced engineered mass timber. Most importantly, this project has demonstrated that the Passive House standard can provide value to private commercial building owners without incentives or subsidies. The primary motivation for the owner was not sustainability, but rather that of creating a quality working environment for staff. Also, he realized that investing up-front could achieve lower operating, maintenance and life cycle costs Overall, the typology and scale of this project sets it apart from other Passive House projects in the region, encouraging the expansion of this approach beyond the residential sector. The project demonstrates that massive improvement in energy performance is achievable in a commercial office building, even on a challenging site, with builders who lacked experience in high performance buildings. The goal of achieving Passive House certification influenced decision making from the start. The site constraints precluded the construction of underground parking, so bridging the building over a surface parking lot was both logical and environmentally beneficial – eliminating a significant volume of concrete from the project.

Excluding the ground floor, elevator and exit stairs from the Passive House envelope, reduced the heated floor area to 1,000m2, improved the form factor, and avoided thermal bridging and air tightness challenges at junctions between foundations and superstructure. The structural engineers minimized the use of steel and concrete, meeting the considerable challenges of an asymmetrical structure in a high seismic zone using mostly CLT panels for shear walls and floors, within a glulam post and beam frame. In the absence of local trades familiar with Passive House construction, particularly the requirements for a tight and continuous envelope, much consideration was given at the design stage to the sequencing of trades for quality control. A three-layer system for the envelope was designed, each associated with work for a particular sub-contractor: structure, thermal and air barrier, and cladding. The structural sub-trade and the cladding sub-trade did not have to do anything differently from what they normally would, and the crew that did have training in high-performance envelopes came between them to do the sensitive work. Internally, much of the mass wood structure is exposed. At the centre of the building, a large stair and atrium acts as a gathering space and offers an attractive alternative to the elevator when travelling between floors.

This new building provides CHV with the opportunity to expand its existing services, including an enlarged drop-in program (support, meals, laundry, showers), a short-stay sanctuary program for youth in crisis, staff areas associated with the youth programs, administrative areas and much needed recreational opportunities. The site is located on the southern edge of the Downtown core, across the street from the original CHV building. This provides continuity of presence for youth to connect with the staff and programs. In addition to a commitment to social sustainability, Covenant House Vancouver achieves a significant level of environmental sustainability. Environmental design strategies include: optimized exterior wall assemblies; low window-to-wall ratio; high level of daylighting throughout the building; energy recovery ventilation; reduced lighting power density and a reduction in domestic water consumption.

3. The residential suites comply with ASHRAE Standard 55, Thermal Comfort Conditions for Human Occupancy. SLOAN electronic faucets and ELKAY water stations (both from Dobbins Sales) have helped to reduce water consumption by 44%. 4. The building design supports the youthâ&#x20AC;&#x2122;s search for a psychological and physical sanctuary through the provision of supportive indoor and outdoor areas. 5. Durable, maintainable building components were selected under a Building Durability Plan informed by CSA Standard S4788-95, and interior materials, such as resilient flooring in the form of rubber base, rubber tile, stair stringers, transition strips and Centiva Heritage Plank supplied by Tarkett, have minimal VOC content. The cooling system and fan coils use Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric Sales Canada.

Heating and cooling is provided through a Variable Refrigerant Flow (VRF) fan coil system. Fan coils are connected to a common VRF Outdoor Unit (ODU) with heat recovery capability. Shared fan coil loads across the VRF system provide virtually free heat recovery between fan coil units. Energy savings are projected to be 32% better than the reference. With a limited budget, the design and sustain-

ability measures had to be simple and practical in order to provide CHV with a low-maintenance, efficient building. The design approach was developed through a series of integrated workshops, extensive energy modelling, and costing exercises. Beyond providing supportive housing for homeless youth, the design mandate was to achieve LEED Gold and reduce the use of fossil fuel energy. The building design was also intended to support the need for a psychological and physical sanctuary for youth through the provision of supportive indoor and outdoor areas. Program spaces received careful design attention in order to provide a positive and welcoming environment. These measures include: the selection of materials and colours to reflect principles of trauma-informed design; comprehensive daylight and view strategies to emphasize a meaningful connection between occupied areas of the building and outdoors; building configuration and planning to maximize daylighting, reduce reliance on artificial lighting, and let occupants benefit therapeutically from visual access to outdoors; and the planning of interior and exterior spaces which allow freedom to choose between social contact or privacy. Public education underpins the design and operation of Covenant House Vancouver, raising the awareness of street-engaged youth and simultaneously reinforcing their right to live in safe and respectful conditions designed to the highest environmental standards.

SABMag - FALL 2020

The renovation to the Bata Shoe Factory is an ambitious adaptive re-use project located at the gateway to Batawa. Central to Mrs. Bata’s vision for Batawa was the conversion of the manufacturing facility built by her family’s shoe empire during WWII, into a modern mixed use residential, commercial and community building with a light environmental footprint and a social mandate.

With a focus on integrating the most sustainable approaches – the renovated building retains the original 1939 concrete structure; the HVAC systems are powered entirely through a geothermal energy source; and any new materials or systems are as sustainable as possible – the resulting renovated building is a model for increased housing density in a rural setting with the lightest impact on the environment and a focus on community and social sustainability. Aside from not building at all, the lightest impact on the environment is accomplished through adaptive re-use strategies – retention and rehabilitation of existing buildings. With close to 80% of a building’s embodied carbon found in the structural components, retaining and highlighting the existing concrete structure of the building in combination with new sustainable materials and systems was one of the key strategic decisions for this adaptive re-use project.

Another key decision was to revive cultural values and sustain the local community. The original shoe factory, when it was in operation, provided jobs for the town, a sense of community, and even fitness and education programs; it was the force that bound and oriented the local community. The same philosophy was taken in the revitalization of the building, through the creation of community spaces, new retail spaces, a daycare, and 47 high-quality rental residential units on the upper floors of the building.

The decision to use onsite geothermal energy for 100% of the HVAC needs of the building and the omission of natural gas as an energy source was a key factor in energy savings and minimizing long-term CO2 emissions from building operations. The choice had the additional environmental benefit of catalyzing the greening of the site through the removal of the large area of concrete paving that surrounded the existing factory building on three sides. A new parking area with extensive green space was built on top of the geothermal field.

1 1. Partial view of south elevation as seen from the waterfront.

Battersby Howat Architects Residential [Small] Award Jury: A beautiful example of how the transparency, openness and site responsive character of traditional West coast Modern design can be integrated with the high-performance requirements of Passive House. The project is also notable for its prefabricated cross laminated timber structure. The project team also made a commendable effort to provide educational and other benefits for the community, creating a video series about the project and by donating demolition and surplus construction materials to Habitat for humanity.

Located on the West Vancouver waterfront, the West Bay Passive House achieves a rare fusion of beauty and efficiency in its pursuit of net zero energy performance. With a super-insulated, airtight envelope and highly efficient mechanical and electrical systems, the home achieved a Passive House Plus certification, an Energuide Rating confirming zero tonnes of Green House Gas emissions, and net-zero Giga-Joules of energy consumption when measured on an annual basis.

Other notable attributes of the house include the use of a CrossLaminated Timber (CLT) superstructure constructed on top of a concrete foundation, floor-to-ceiling glazing for uninterrupted ocean views, and a passive solar design achieved through a combination of built-in and environmental shading. Located in one of Metro Vancouverâ&#x20AC;&#x2122;s luxury home markets, this project introduced a sustainability-conscious design ethos to the area by creating

a home that was both architecturally pleasing and Passive House certified. Capturing the ocean view was critical to the success of the design so triple-glazed thermally-broken glazing systems were used to minimize heat loss and overhangs designed for passive shading. The superstructure was built with factory prefabricated CLT panels to provide a robust and durable building core that would also store carbon. By prefabricating the components, the construction schedule was reduced by two months with a significant reduction in waste. The active mechanical system consists of an energy recovery ventilator (ERV) for ventilation and a heat pump hot water tank. The same small heat pump also feeds a heating and cooling coil on the ERVâ&#x20AC;&#x2122;s supply lines and is able to provide a comfortable indoor environment for all occupants. The project team took a proactive role to educate the community, youth, municipal officials, tradespeople, and building professionals through a video series, seminars, open houses, and media interviews to help advance the green building movement. As a result, the municipality has introduced an FSR relaxation for high efficiency homes that require a greater thickness of insulation.

4. Balanced ventilation with energy recovery provides continuous filtered fresh air and ensures optimum indoor air quality. The active mechanical system consists of a Zehnder ComfoAir Q600 energy recovery ventilator (ERV) for ventilation and a Daikin heat pump. 5. Natural light is brought into the home through strategically placed windows on all four facades. 6. The entry from the waterfront side. Quad-Lockâ&#x20AC;&#x2122;s Airfoam insulated concrete form system used for the foundation provides high energy efficiency and higher safety ratings at a lower cost of ownership.

REACH GUESTHOUSE PRINCE EDWARD COUNTY, ON

Kearns Mancini Architects Residential [Small] Award Jury: A meticulous rehabilitation and upgrade project, that converts a 19th century four-bedroom farmhouse into a 2-bedroom guesthouse, with the original post and beam structure being enclosed in a new high-performance building envelope. The addition of a Passive House standard kitchen, dining and living area to the rear of the house integrates seamlessly with the original, being barely discernible as a new structure. An elegantly detailed project notable for its restraint.

Originally a four bedroom, oneâ&#x20AC;?bathroom house, this 19th century farmhouse was renovated into a two bedroom, twobathroom house incorporating Passive House EnerPHit standards. Conceptually, a new insulated, airtight structure was built over the existing post and beam house. The rear of the building was substantially rebuilt to accommodate a large, double height kitchen, dining and living space. The new front gable window was intentionally oversized, offering visitors a glimpse of the original arched front gable window within. In future, the house will serve as a guesthouse for a new great house on the same property. In the interim, it serves as a

1 1. The front entrance. The project retains over 85% of the existing structure, and sets a precedent for the repurposing of abandoned municipal buildings.

Hobin Architecture Existing Building Upgrade Award Jury: This conversion of a 1940s City Works Yard building into an Innovation Hub demonstrates how the careful and pragmatic adaptive reuse of an unprepossessing building can transform the dynamics of a neighbourhood, create a sense of place, and at the same time support social and cultural continuity. The act of preservation conserves embodied energy in the existing structure and avoids that associated with a new building. The LEED Gold certification is exemplary for an adaptive reuse project.

Also known as The Innovation Centre at Bayview Yards, Cours Bayview Yards is Ottawaâ&#x20AC;&#x2122;s epicentre for entrepreneurial programs and services. The centre was developed within a 4,460 m2 (48,000ft2) industrial building, originally constructed in the 1940s as a City Workshops facility, and now having historical importance as one of the few survivors of a once sprawling industrial area.
