I AM THE RIVER

Member Canada Green Building Council

Overshadowed by the COVID-19 pandemic, resolution of the pipeline protests of this past spring remain a work in progress. The proposed construction of the Coastal Gas Link Pipeline through the ancestral territory of the Wet’suwet’en First Nation in British Columbia’s Bulkley Valley, has again exposed the deep divisions between First Nations and the governments of British Columbia and Canada.

This dispute is not about a single pipeline, but the recognition of Aboriginal rights and title, what those rights are, who holds them and over what territory they extend. A one-page intergovernmental MOU signed in mid-May confirms that the Wet’suwet’en Hereditary Chiefs have authority over their traditional territory (not simply their reserve) and ambitiously commits to resolving generations-old land-use issues within 12 months! photo: Roy Grogan

If not simply preoccupied with righting past wrongs, but rather offering a vision for the future, this memorandum may help redefine our relationships with one another and the environment, so we may thrive together on this Earth. Here we may take inspiration from New Zealand. In 2017, after more than a century of land claim disputes with the Maori people of the region, the country’s national government granted legal status to the Wanganui River and by implication, its 7,500 square kilometre watershed. The country’s third longest river (coincidentally a similar length to the Bulkley) is sacred to the Maori, being the route by which their ancestors first explored the interior of the land they called Aotearoa, during the Polynesian migrations of the first millennium. The Maori have a deep physical, spiritual and philosophical relationship with the River, its life being literally inseparable from their own. Bestowing legal rights on the river equivalent to those enjoyed by individuals and corporations, was simultaneously pragmatic and visionary. These rights, which are protected by two Trustees appointed jointly by the local Maori tribe and the national government, have yet to be tested, but this precedent-setting legal protection has settled all outstanding land claims and laid the foundation for a new relationship based on mutual respect and understanding. Both parties agree that ‘legal entity’ status is the best approximation the law can make to the Maori belief system, best captured in their traditional saying, ‘I am the River and the River is me’.

NEWS RAIC REPORT Main Street Design Challenge launched to foster innovation in Urban Design By Tanner Morton, Communications Coordinator A new Canada-wide design challenge launched on June 3, 2020 to generate responsible, sustainable, and resilient design solutions to be implemented during COVID-19 recovery, and post-pandemic, on affected main streets across the country. The Main Street Design Challenge (MSDC), developed by the Canadian Urban Institute (CUI) and the Royal Architectural Institute of Canada (RAIC), invites all Canadian resi-

CPCI RELEASES NEW EPDS FOR WALL PANELS AND STRUCTURAL PRECAST CONCRETE

dents interested in place-making and design to develop solutions to help build the resiliency of main streets across the country. The Challenge demonstrates how thoughtful and innovative design plays a key role in the revitalization of main streets, including kickstarting the economy, fostering vibrant, liveable, and healthy communities, increasing public safety, reducing social isolation, and restoring the public’s confidence to return to streets and public spaces. An online portal opened for submissions on June 22, 2020—with deadlines for the dif-

ferent cycles of the competition. All submissions meeting the project guidelines will be published online on a rolling basis in a free, open-access Main Street Design Playbook on October 5, 2020—recognized across the globe as World Architecture Day. The Main Street Design Challenge is an initiative of Bring Back Main Street a nationally coordinated research and action campaign by the CUI to ensure the people, businesses, and organizations that recognize the main streets of cities and towns across Canada as a vital heart of their community.

The Canadian Precast Prestressed Concrete Institute (CPCI) has released new environmental product declarations (EPD) for Architectural and Insulated Wall Panels and for Structural Precast Concrete Products. The new EPDs allow architects, engineers, building owners, and other specifiers to better understand the environmental impacts of precast and prestressed concrete products. The industry-wide EPDs, jointly released by the Canadian Precast/Prestressed Concrete Institute (CPCI) and the Precast/Prestressed Concrete Institute (PCI), are issued within clearly defined product groups based on the precast concrete Product Category Rules (PCR).

The EPDs were independently prepared by Athena Sustainable Materials Institute in accordance with ISO 14025 and ISO 21930; the Product Category Rules for Preparing an Environmental Product Declaration for Precast Concrete (UN CPC 3755). They were also independently verified by ASTM International (in accordance with ISO 14025) and by ndustrial Ecology Consultants (in accordance with ISO 14025 and the Product Category Rules).

EVOLVE1 RECEIVES MITSUBISHI ELECTRIC’S SUSTAINABLE BUILDING OF THE YEAR AWARD evolv1 is the first office building in Canada to receive the Zero Carbon Building-Design Certification from the Canada Green Building Council. According to the CaGBC’s Zero Carbon Building Standard, the certification means the project modelled a zero-carbon balance for future operations, incorporated an efficient energy and ventilation system to meet a defined threshold for thermal energy intensity, and designed onsite renewable energy systems capable of providing a minimum of 5% of building energy consumption.

SABMag - SPRING/SUMMER 2020

The building was designed to not just maximize energy efficiency, but to produce 108% of its energy needs. As part of this mandate, all components needed to be energy-efficient, including the HVAC system. Mitsubishi Electric Heating and Cooling was selected to supply 100% of the heating and cooling to the office building. Specifically, Mitsubishi Electric’s City Multi Water-Source VRF Heat Recovery System was chosen because it not only regulates the flow of refrigerant to the fan coils, but it also changes the water flow rate to minimize the pumping energy.

The Mitsubishi Electric heat pump system is also very quiet, and is a great solution for office, commercial, education and residential applications. Thirty-six outdoor units and 148 indoor units were used in the 104,000 square foot building. On February 14, 2020, a tour was given to Terada-san, President and CEO, of Mitsubishi Electric Sales Canada Inc. along with Dermot McMorrow, VP and GM, Syed Abid, Commercial Sales Manager and Tova Davidson, Executive Director of Sustainable Waterloo. Adrian Conrad, Chief Operation Officer of the Cora Group hosted the tour. The Cora Group was awarded Mitsubishi Electric’s Sustainable Building of the Year Award. Congratulations to the Cora Group for their success in sustainable building development. 1.Terada-san, President and CEO, of Mitsubishi Electric Sales Canada Inc. presents Mitsubishi Electric’s Sustainable Building of the Year Award to Adrian Conrad, Chief Operation Officer of the Cora Group. 2.The evolv1 building.

ENERGY-EFFICIENT, DURABLE AND AFFORDABLE: A NEW TAKE ON FIRST NATIONS HOUSING When architect Douglas Cardinal contacted Maisons Chicoine Homes (MCH), a builder located near Gatineau, QC, with a vision to create a new housing model for First Nations communities, the result was Cardinal House. The two-storey, 1,100-square-foot, three-bedroom home uses prefabricated floors and exterior wall panels of cross-laminated timber (CLT) from Element 5 which were factory made, then trucked to the site and assembled in three days by MCH. The Cardinal House concept offers a healthy (mouldresistant), energy-efficient, long-lasting and affordable home to meet the housing needs of First Nations communities.

PRODUCTS ISOKORB® STRUCTURAL THERMAL BREAKS INSULATE BALCONIES IN HALIFAX HIGH-RISE

SEE A LOT MORE PRODUCTS at SABMag’s 2020 Directory of Sustainable Products and Services for Sustainable, highperformance building organized by product category and by LEED category. https://sabmagazine.com/product-directory/

Maple Apartments is one of the largest mixed-use residential high-rises in downtown Halifax. Developer Southwest Properties aimed to create a “contemporary, iconic addition to the urban landscape” while minimizing the building’s energy use. Structural thermal breaks helped achieve these goals by limiting heat loss through the floor slabs by thermally isolating the building’s cold exterior balconies. The inclusion of structural thermal breaks between the interior floor slabs and exterior balconies greatly reduces heat loss through the penetration, while increasing the temperature of interior floors by up to 19°C compared to non-thermally broken slabs during cold weather periods. The design team specified the Isokorb® Type CM load-bearing structural thermal breaks by Schöck North America.

www.fensturwindows.com 8

SABMag - SPRING/SUMMER 2020

The thermal breaks consist of a graphiteenhanced polystyrene insulation module that runs the full length of the slab. Stainless steel reinforcing bars are positioned at the top of the insulation module to accommodate tension forces imparted by the cantilevered slab. Compression concrete modules placed at the bottom of the assembly transfer compressive forces from the cantilevered slab which, in conjunction with the tension bars, accommodate the moment at the connection. Additional stainless steel reinforcing bars run diagonally through the insulation body to address shear loads at the connection. By minimizing the cross-sectional area of the structural elements that penetrate the insulation body, as well as using less thermally efficient materials (stainless steel transfers 70% less energy than mild carbon steel), structural thermal breaks can reduce heat transfer by up to 90% at the connection.

NEWS CERTIFICATION/QUALITY ASSURANCE A VITAL PART OF THE NATIONAL BUILDING CODE IN ERA OF UNCERTAINTIES The main threats to infrastructure assets are many but include first and foremost damage or destruction caused by extreme weather events. These threats have led to Infrastructure Canada’s Climate-Resilient Buildings and Core Public Infrastructure Initiative. Led by the National Research Council of Canada (NRC) this “ground-breaking work focuses on integrating climate resiliency into building and infrastructure design, guides, certification and codes.” The federal government’s new LCA initiative (low-carbon assets through life cycle assessment) guidelines will enable public and private sector portfolio holders to incorporate the quantification of Life Cycle Carbon & Total Cost Of Ownership (TCO) of built assets (real property, public infrastructure) into their procurement processes. For more information: https://www.infrastructure.gc.ca/plan/crbcpi-irccipb-eng.html and https://nrc.canada.ca/ en/research-development/research-collaboration/programs/low-carbon-assets-throughlife-cycle-assessment-initiative This work will contribute to an infrastructure landscape that can keep Canadian communities safer from extreme weather and deliver the Best Bang for the Buck (lowest total cost of ownership). When it comes to purchasing certified buildings and above- and below-ground infrastructure products, the best value comes from the appropriate durability and resilience over the entire lifecycle. So how to achieve best value for an investment? We know that specifying products that meet the right building code standard is a minimum first step. Specifying products that meet a certification program built on superior quality assurance processes, above and beyond the minimum building code standards, will protect your investment, manage risk, and provide safety assurance to your end users, tax payers, and/or service community.

Why Precast Concrete Certification? Certification helps ensure that the essential components of a quality assurance system are present and functioning properly, resulting in the highest probability of reducing risk, meeting specifications, and completing a successful project. Therefore, the primary purpose of a certification program is to help ensure that products are manufactured in accordance with specifications and community expectations. In other words, certification helps ensure “as designed becomes as built” and should be considered by every designer as a means of reducing risk and ensuring quality and safety.

The Canadian Precast Concrete Quality Assurance (CPCQA) Certification Program The national and provincial building codes require conformance to the CSA standards for precast concrete materials and construction when it comes to structural, architectural and drainage precast concrete products. CPCQA is a nationally recognized and accepted certification program that provides an independent third-party certification of conformance to the CSA standards. The CPCQA certification program requires precast concrete manufacturers to meet the requirements of the latest editions of CSA Standards for structural, architectural and drainage products and the PCI Quality Control Manuals MNL-116 and 117 (US equivalent), with the more stringent requirements being the governing criteria. Certified plants are audited annually with at least two unannounced audits. Strict compliance with published standards is necessary to maintain certification. Certification confirms a manufacturer’s capability to produce quality products and systems.

Continuous Feedback and Addressing Client Concerns CPCQA has two key client groups – the owners / agencies / specifiers who specify the program and the precast concrete producers who participate. Both of these groups have formal methods for providing feedback to the Quality Assurance Council on the program. Addressing this feedback is a formal part of the QAC agenda at each of their three annual meetings. Owners or specifiers concerned about the quality of precast concrete from a CPCQA certified plant can fill in the Quality Concern Reporting Form on the CPCQA website and submit it confidentially to the Managing Director of CPCQA at QACAdministrator@precastcertification.ca. CPCQA is the only certification program in North America that has an official Quality Assurance Reporting Program and Quality Conflict Resolution Mechanism. At present the Canadian Precast Concrete Quality Assurance (CPCQA) Certification Program certifies over 80% of the precast concrete production in Canada. The CPCQA program is the only program endorsed by the Canadian Precast/ Prestressed Concrete Institute (CPCI) and the Canadian Concrete Pipe and Precast Association (CCPPA).

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.

CANON CANADA HEADQUARTERS, BRAMPTON Canon Canada’s 176,000 square foot, LEED Gold certified headquarters building is designed to communicate Canon’s brand values of clarity, precision, and technological elegance. This five-storey building is comprised of a silver-white curtainwall with vertical fins of fritted glass that float effortlessly above a recessed base of black granite. Canon Canada’s office demonstrates a creative approach to sustainability and design while promoting a healthy lifestyle for its employees. In 2019, Canon Canada was named one of Canada’s Greenest Employers. The building site, surrounded by landscaping, was key to ensuring Canon’s vision for a "building within a park," allowing generous views and connections to nature. Expansive outdoor terraces are linked to a serene walking trail that meanders around a stormwater management pond buffered by a naturalized meadow of native plantings, serving both Canon Canada and the residential community.

A highly sophisticated and energy efficient building automation system controls the indoor climate, under-floor air distribution, lighting systems, window blinds, A/V and security systems and provides optimized comfort for all staff. With this project, Canon Canada leads by example, going beyond the status quo in an area ripe for development. The building invigorates the local economy and encourages the development of a balanced and sustainable city where people can live, work and play in harmony.

The building includes a system that collects, filters and stores rainwater in a cistern underground. Once rainwater is filtered and available for use, domestic city water use is automatically shut off and the building begins to use the rainwater for flushing and irrigation. The system saves at least 20% of our domestic city water usage per year – the equivalent of 4.5 million water bottles (500 mL). The building’s biophilic interiors balance privacy and collegiality in an open and serene environment with offices oriented around a bright and airy central atrium, where daylight gently washes over travertine floors, western red cedar-slatted ceilings and tranquil rock gardens. Ergonomic furniture, interior plantings, individually-controlled lighting and low-VOC materials further enhance staff well-being. The carefully detailed vertical glass fins integrated into the exterior glazing provide solar shading and reduces indoor solar head gain and glare.

AGRICULTURE PLACE, REGINA Agriculture Place is an 11-storey office tower in downtown Regina. This LEED Gold project captures a building design thatâ&#x20AC;&#x2122;s responsive to the pedestrian condition at grade, through open interior spaces and public support functions; public seating with planters and bicycle storage; three levels of underground parking to maximize density; integrated art in the atria; and retail opportunities for tenants. The faĂ§ade has an integrated deluge sprinkler system that allows larger windows to take advantage of natural light and views (over 90% of the occupied spaces have exterior sight lines), while allowing the tower to be located closer to neighbouring buildings, densifying the site consistent with the downtown plan. The building is linked to the original tower via a Level 2 podium, as well as through the underground parkade. With a Walk Score of 92, the building is very close to multiple public transportation options; has carpooling stalls onsite; secure bicycle storage; and showers and locker facilities. Water-conserving plumbing fixtures and multiple recycling options contribute to conservation efforts, and all materials were selected to meet LEED criteria for low emittance. Over 50% of wood materials were harvested from sustainable forests designated by the Forest Stewardship Council; an additional 22% are considered regional; and nearly 80% of construction waste was diverted from traditional waste streams to end-use recyclers.

BLOOR ISLINGTON PLACE, TORONTO Located at 3250, 3280 and 3300 Bloor Street West in Toronto, Bloor Islington Place is a 884,000 square foot on-transit office complex with three office towers interconnected by a full-service retail podium. Built between 1981-1991, this multi-purpose commercial complex offers a variety of tenant amenities including a gym, daycare, sit-down and take-away food options, health care providers, a national grocer and a green roof complemented by extensive underground parking.

THE REGIONAL MUNICIPALITY OF YORK Office at 145 Harry Walker Pkwy., Newmarket, ON The Regional Municipality of York has a long-standing commitment to designing and constructing sustainable buildings. Since 2016, 17 York Region buildings have been certified under the LEED green building rating system. The Regional office at 145 Harry Walker Parkway in Newmarket, Ontario was most recently awarded LEED Silver certification in May 2019 under LEED Canada for New Construction and Major Renovations 2009.

(Photos: ÂŠAECOM. Mike Niedringhaus)

The renovations at 145 Harry Walker Parkway were completed in 2016; they comprised the partial conversion of a 27-year-old, 14,800 m2 warehouse into a 5,100 m2 administrative office building for more than 300 occupants while retaining the remaining warehouse for storage. The project began with an integrated LEED design charette involving the design team and representatives from York Regionâ&#x20AC;&#x2122;s Property Services branch. Partially converting a large warehouse with solid metal cladding into an administrative office to accommodate over 300 workstations, multiple private offices, and training and conference rooms presented a few challenges. One of the challenges the project had to overcome was to find a way to incorporate adequate daylight to ensure occupant comfort and energy savings. To achieve this, new fenestrations on the building envelope were introduced; including three skylights and two sizable thermally broken curtain walls to bring natural light into the office space. The curtain wall system features a combination of highperformance, low-emitting insulating clear and translucent glass units which transform the sunlight into glare-free daylight. The lighting within the office space was further enhanced through the installation of LED light fixtures with indirect/direct light distribution, occupancy sensors and daylight controls.

The LEED design charette also considered the improvement of energy performance and water saving strategies such as; replacing the roof with high R-value insulation and high albedo roof, optimizing HVAC and lighting efficiencies, enhanced commissioning through implementing measurement and verification system, selection of salt- and drought-tolerant landscape design requiring no irrigation, and installing low-flow plumbing fixtures. Other notable sustainable strategies included selection of low-emitting building materials with regional and recycled content, a new stormwater bioswale, construction waste diversion management and construction indoor air quality management. In addition, the provision of showers, bike racks, electric vehicle charging stations and carpool spaces promotes sustainable transportation. The 145 Harry Walker building demonstrates how aging industrial space can be transformed into modern, welcoming and sustainable office space.

TRANSFORMATION

By Chris Ballard, CEO of Passive House Canada

We’ve seen rapid adoption of the Passive House Standard, not only among industry professionals wanting to build better for clients, but from government of all levels recog-

Passive House Canada was created with a simple premise: to change how Canada builds and retrofits its buildings for thermal comfort, health, resiliency and low energy. And it’s happening. We are changing the marketplace through education and advocacy, by running local and national events, and by providing excellent member services. Our founding members recognized that market transformation would only be achieved if there was fundamental government policy and regulatory reform. They understood it could only be achieved if quality education courses were developed, national and international networks created and members were supported in their communities. When the founding members first met in 2013, such transformation was a distant dream, but the world has been quickly waking up to the reality of climate change, the need for better buildings and bringing public policy in line with our mission. Today our fundamental mission is still to make high-performance Passive House buildings the norm through the advancement of public policy and an effective regulatory framework which will improve building codes and standards across the country.

nizing the important role that high performance buildings have in reducing energy consumption and greenhouse gas (GHG) emissions. The successes that we have experienced are directly attributable to the dedication of industry professionals and elected officials who are passionate about sustainability. Their momentum and drive have given us the privilege of assisting all levels of government in building policy development; of supporting the growth of a national membership of over 1,200 members (in eight provinces and two territories); and of delivering hundreds of training courses to over 5,000 registrations across Canada. Over 10,000 people subscribe to our newsletter and bulletins, and scores more learn about Passive House building standards through our social media platforms. Transforming how Canadians build buildings is not easy. In the face of the work ahead, it is important to stop and celebrate why so many of us are invested in this process. While the initial driver is, of course, environmental, and the common goal is to mitigate climate change, this alone does not catalyze market transformation, represent the motivation of everyone involved, or simplify the process of managing change.

The plan is a simple double-loaded corridor scheme with inset stairwells, central elevators and a 9-degree bend, symmetrical through the centre of the building. This simple gesture accentuates the main entrance when viewed from the street, orients half the building faรงade further towards the south, creates a natural break in the west faรงade, accommodates exterior balconies connected to common amenity rooms on each floor, and provides a larger landscaped setting for the ground-level suites on the east side. The north-south orientation provides each tenant access to direct sunlight and realizes an optimum use of the site with quality outdoor spaces. Each faรงade is designed to respond to the specific solar orientations of the site, while maintaining a cohesive character that is complementary,

yet distinct from non-passive house, multi-family housing in the community. The main exterior cladding is a cementitious rainscreen

system, with deep recessed triple-glazed fiberglass windows and metal flashing surrounds. To achieve the required 200 mm insulation thickness and facilitate installation of exterior strapping, the thickness of the exterior plywood sheathing was increased, eliminating the need to blindly fasten the exterior strapping through to structural studs. This gave flexibility for placement of cladding strapping to suit the cladding joint patterns and colour changes.

Not only did this construction method improve the construction schedule, the ease of maintaining the air barrier resulted in an air tightness reading of 0.2 air changes per hour in the final pressurization test. A mono-sloped roof system was built continuously under the mechanical penthouse to reduce the surface area of the Passive House envelope. The single-sloped roof is drained to the east through four scuppers connected to rainwater leaders aligned flush with the exterior cladding, avoiding unwanted roof penetrations and diverting roof water directly to rain gardens below.

The building is heated and cooled by a heat recovery variable refrigerant volume air source heat pump system. The suites are ventilated by a central ERV, providing both fresh air supply and exhaust air extraction. The main floor auxiliary rooms have smaller dedicated ERVs. All lighting fixtures are LED. Daylight sensor switches are used to control lights in common areas where enough daylight can be used and exterior lighting fixtures are controlled by photocells. The south façade incorporates larger windows into the living spaces, shaded with lightly louvered horizontal sunshades. North-facing windows are minimized with main living spaces receiving daylight from the east and west wherever possible. More than 90% of occupied spaces are within 7m of a window.

Riptide House Fresh take on traditional design provides high-level living comfort By RHAD Architects

Just as a riptide in the ocean is a strong counterflow against a prevailing current, so Riptide House in Dartmouth, Nova Scotia represents a powerful oppositional force against the standard housing practices in Canadian cities. The clients, an East Coast surfing family, wanted a home that would fit in with their established urban neighbourhood, while simultaneously addressing the environmental issues faced by our society.

1 2

As designers, our challenge was to respect the historic vernacular of the neighbourhood, while creating a contemporary house with superior energy performance based on passive design principles. The modernization of the deep-rooted wooden gable typology characteristic of homes on the Atlantic coast resulted in a modest 123 sq.m,, three-bedroom home with a potential secondary basement suite to encourage urban densification. The house replaces an older structure that was set back from its neighbours toward the rear of the north-facing lot. The new house is positioned to unify the streetscape, to increase the size of the south- facing rear yard and create a private courtyard for the family. The simple gable form was cut and slid apart, creating a primary volume containing the living and dining areas and kitchen on the main floor and bedrooms upstairs; with a secondary volume containing the laundry room, washroom and stairs. The traditional form was refined by tight eaves detailing and a clean, simple and durable palette of material, including V-groove cedar siding and corrugated aluminum. The shift in plan creates the opportunity for a covered front entry from the street and a mudroom entrance from the south-facing rear courtyard. The design is familiar enough to fit in, yet different enough to stand out. This difference creates an educational opportunity for members of the community interested in the energy saving strategies and other environmental features of the house.

In a small house, the quality of natural light and ventilation are particularly important. Fenestration has been optimized for passive performance, with larger windows on the south side and smaller ones (consistent with neighbouring houses) on the other sides. The deep set, operable windows, are placed at the centre of the 250mm fiberglass insulation layer to minimize thermal bridging, and also provide the shading necessary to avoid overheating in summer. The high levels of insulation, air tight envelope and triple glazing throughout, combined with controlled fresh air ventilation from HRV units results in significant energy savings, excellent indoor air quality and a high degree of thermal comfort. An interior service wall located inside the vapour retarder accommodates all of the electrical and plumbing without disrupting the vapour retarder, or the insulation value of the wall. In order to make it the most cost effective, and to limit the amount of square footage lost to the service wall, we placed the service walls very strategically, where required, instead of throughout the entire exterior perimeterÂ of the house. With its modest size, simple form and straightforward, energyefficient detailing, we believe this project offers an object lesson in affordable and transferable sustainable design. A Walk Score of 74 and a Bike Score of 83 further support the ownersâ&#x20AC;&#x2122; desire for a lifestyle with a low carbon impact.

Aurora Coast

Cannabis Innovation Centre Well being, energy and water conservation top the list at research station By Heidi Nesbitt

Aurora Coast is a new cannabis research centre located in the Comox Valley on Vancouver Island. This unique facility provides a supportive and nurturing workplace for Auroraâ&#x20AC;&#x2122;s scientists to expand their genetics and breeding research, with the goal of realizing the full human benefit of the cannabis plant. 1.

Context The project aims to transform public perception of a previously illegal, underground industry, by housing it in a facility that fosters creativity and innovation. The first phase of the project consists of a mass timber building containing offices, labs, meeting rooms and support spaces for the adjacent greenhouse. A transparent network of collaborative workplace hubs was designed to encourage informal interaction and enhance the creative potential of the research team. As a project centred around plant health and vitality, every aspect of the building and site is designed to connect occupants to nature and to support health and well-being: an exposed, mass-timber structure was chosen for its low environmental footprint, and to provide a biophilic backdrop to what might otherwise have been a sterile laboratory environment; clerestorey windows bring natural daylight deep within the high-security, restricted-access areas; and views are provided to the restored pollinator habitat and orchard that surrounds the building.

Cannabis facilities face unique challenges, including security, odour control and public stigma. To help gain the support of the local community, a large, environmentally degraded, industrial site at a prominent intersection was rejuvenated by providing extensive, on-site stormwater management, and by restoring the ecological integrity of several hectares of land. The larger environmental challenge was to provide cannabis plants with the steady warmth, light and water they need to thrive without creating additional strain on local resources.

OCH Carlington Hub Passive House the most cost effective for seniors housing and health centre By Stephen Pope and Marc Mainville

This new four-storey development in Ottawa serves as a mixed-use “hub” which combines affordable seniors housing for Ottawa Community Housing (OCH) with the Carlington Community Health Centre (CCHC). Affordable rental housing for seniors includes 42 independent living rental apartment suites on the upper three floors. The project marks the first time the city’s public-housing agency has partnered with a community health centre to build independent-living units for seniors with on-site health services.

SABMag - SPRING/SUMMER 2020

Services include a medical clinic, diabetes clinic, community meeting spaces, nutrition consultants, seniors’ cooking, exercise and other classes, and a choir. Residents of this building have a welcoming and supportive environment to learn new things, meet new people, improve their quality of life and have fun. The existing Community Health Centre, to which this project connects, sits on the eastern end of the site. The four-storey addition extends along the west side of the existing building and has a generous yard providing individual suites with unobstructed views and lots of natural light.

1. The project is four storeys of independent-living units for seniors with on-site health services â&#x20AC;&#x201C; a first for the city. Alumicor supplied the thermally-broken curtain wall, which contributed to the overall energy efficiency of the OCH building envelope. 2. The Community Room. Right-sized ventilation passed through an 83% efficient ERV and 1 kW duct heaters provide heat to the residences. 3. The front entrance garden.

Site plan

The long building has been articulated to break down the mass and add visual interest along Coldrey Avenue. The site was designed to maximize the amount of green space on the property: the 64 parking spaces were the minimum number required to comply with local zoning bylaws and new trees have been incorporated throughout the site (specifically in the parking lot to reduce the amount of asphalt). Internally, apartment units are designed with an open-concept to maximize the sense of space within a very compact layout. Windows are sized to optimize and balance the need for light and quality of view with energy efficiency demands on heating and cooling. The large windows have an operating section that gives residents access to the sounds and smells of the neighbourhood. Operable windows are not needed for fresh air as the balanced ventilation system is designed with a capacity for two persons per suite but is run at 0.36 ACH, or 30 m3/h/ occupant. Public corridors, stairwells and common laundry rooms all feature large windows to provide natural light and a connection to the exterior throughout the facility. In accordance with the principles of the WELL Building certification, the design has a strong connection to nature both in the layout and the use of materials. Exposed wood accents are used throughout the building including two mass timber canopies and vestibules at the main entrances. Polished concrete floors are used throughout for durability and cleanliness.

The residences need only a 1 kW duct heater for trim heat. Right-sized ventilation passed through an 83% efficient ERV contributes the balance of the heat needed. Hot water for domestic consumption and clinic air tempering is produced by two 95% efficient natural gas boilers. Lighting is all LED with direct manual switching in the residences, plus occupancy sensors and daylight harvesting in the clinic. With grants for new construction of affordable housing being much easier to obtain than for building operations, the lowenergy Passive House approach is a model that should be

considered for future projects. These types of buildings have long lasting benefits for the community and the environment. STEPHEN POPE, OAA, BARCH, BES, FRAIC, ASSOCIATE ASHRAE IS SUSTAINABILITY CONSULTANT, AND MARC MAINVILLE, MARCH IS AN INTERN ARCHITECT, BOTH OF CSV ARCHITECTS.

Shifting Gears A Passive House Car Dealership in the Making

1. The typical car dealership is ideal for Passive House with its inherently compact form and favourable volume to heat loss area.

By Andrew Peel, Peel Passive House Consulting

The world’s first certified Passive House car dealership opened for business in the fall of 2019. Designed by Cover Architectural Collaborative, Sublime Design and Peel Passive House Consulting and constructed by Black Creek Developments, the 2,420 m2 (26,020 ft2) facility in Red Deer, Alberta houses the new Scott Subaru dealership. It coincides with the 50th anniversary of The Scottsville Auto Group who developed the project.

“Building smarter and showing that retail facilities can still be structured in a way that is functional, and also provide a nicer work environment for employees and customers, has long term benefits. We hope this will inspire others to build similar type structures.”

- Garrett Scott, Owner, Scottsville Auto Group

SABMag - SPRING/SUMMER 2020

Motivation While not an avid environmentalist, owner/developer Garrett Scott sought a low impact building that would support his growing business and recognized the myriad benefits of constructing to the Passive House Standard. This is not the first environmental building initiative Subaru has undertaken. Its Indiana automotive assembly plant was the first zero-landfill factory in the US and inspired the decision to pursue Passive House certification on this project.

Setting the Standard Most, if not all, large car manufacturers have strict corporate standards regarding aesthetics, layout, and service requirements for their facilities and Subaru is no exception. In addition to these corporate standards, the client had some of its own. Chief among these was that any decisions made in pursuit of Passive House certification must not compromise customer or vehicle service in any way. An additional major factor impacting the design was the local winter design temperature of -20oF (-29oC). Navigating these requirements proved challenging and demanded the best of the whole design and construction teams.

Base Design The building is divided into three main zones: a showroom, a repair shop, and a car drop-off zone. The showroom includes a car display area, customer reception and lounge and sales offices on the first floor, and back offices, meeting rooms, and staff kitchen on the second floor. The repair shop comprises a ground floor with 6 service bays and parts storage, and a

One key envelope challenge was to mitigate the impact of the 65 per cent glazing on the west facing storefront dictated by corporate design requirements. Red Deer lies between two of the country’s sunniest cities, Calgary and Edmonton, receiving up to 50 per cent more west radiation than is typical in Germany (the conditions for which the Passive House Standard was originally developed). Numerous solar control measures were explored, including overhangs, deciduous tree planting, external blinds, and electrochromic glazing. Ultimately, the only viable option was installing insulated spandrel panels in the top row of glazing coupled with automated operable internal blinds with manual override. Unfortunately, these measures were insufficient to fully mitigate the high cooling load. Another envelope challenge was the client’s original requirement for seven overhead doors. The Passive House consultants devised an alternative design requiring only two doors. However, the client felt this disrupted service too much and eventually agreed to a compromise of four doors. The initial concern with these doors was heat loss due to operation. Investigations revealed minimal air exchange, as the doors are shut quickly after a car passes through them. Car Exhaust Hose. The idea to vent each of the six service bays with a separate exhaust fan, thus cutting the exhaust rate by 83%, had to be modified to a two-fan system which still met the Passive House space heating demand target.

SABMag - SPRING/SUMMER 2020

The greater concern turned out to be standby air leakage. Unfortunately, conventional North American doors are not rated for airtightness, so could not be relied upon. Accordingly, the team looked to Europe both for the doors and for an independent assessment of their airtightness. For this, the project team referenced European Standard EN 13241-1, which defines airtightness classes. The authorâ&#x20AC;&#x2122;s team located a product with an equivalent leakage of 0.04 ACH@50Pa, which increased the whole building leakage by an acceptable 10 per cent. Additionally, careful detailing ensured a durable seal between the door frame and the wall.

Ventilation Ventilation is provided by three ERVs, each serving one zone of the building. The ERVs serving the repair shop and dropoff zone are sized to meet peak loads. The mechanical engineer originally specified an air change rate of 3.0ACH to deal with any pollutants that may build up during servicing. After detailed review, it was agreed to reduce this specification to 2.0ACH to limit energy demand. Car exhaust contains harmful pollutants that must be directly exhausted to the outside of the building. To meet code requirements, each of the six service bays must have 400 CFM of exhaust capacity. Normally, all bays are connected to the same exhaust fan, which results in all bays being exhausted simultaneously, even when only one bay is in use. For this project, it was proposed to vent each bay with a separate exhaust fan, cutting the exhaust rate by 83%. Unfortunately, a coordination issue led

BUILDINGS as a Climate Change Solution

But operational emissions are only part of the problem. A building that achieves zero emissions during its operation is an important step. The other half of the problem now needs to be addressed: material-related emissions. By recent estimates, the production of building materials accounts for approximately 21% of all emissions globally. We cannot adequately address climate change through operational improvements alone; we cannot “net zero” our way out of this. The “embodied carbon” side of the equation needs equivalent focus and action.

By Chris Magwood The focus of green building has long been on reducing impacts… doing “less bad” to the planet and ourselves by shrinking our ecosystem, chemical and climate footprints through conscious design and material selection. But when it comes to our current climate crisis, doing less bad is simply not going to be good enough. The climate science is clear: we collectively need to get to net zero emissions as soon as possible AND remove carbon from the atmosphere in order to meet the targets in the Paris Accord1. The building industry is now tasked with doing “more good” by reducing net emissions to zero and actively contributing to carbon drawdown.

We need to take responsibility for all the emissions we cause through harvesting, manufacturing, transporting and installing building materials because of the sheer scale of these emissions. Tackling these “material emissions” may be easier than you think. The data and tools available to make carbon-smart materials choices is growing rapidly and the evidence of the emission reductions that can be achieved is encouraging. In a study I completed in 2019, a small (930 m2) multi-unit residential building was modelled with a range of different materials that are all comparable in terms of code compliance, cost and

I don’t believe it is hyperbole to say that making the move to zero carbon is critical if we are to stand a chance of slowing the worst impacts of climate change.
