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’.

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).

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.

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).

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 that’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 façade 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.

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: ŠAECOM. 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 Region’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.

As the first municipality in Canada to adopt a Sustainable Building Policy (SBP), The City of Calgary is a leader in promoting green building. The City’s SBP has resulted in over 60 LEEDcertified projects, including Canada’s first two LEED v4 Building Design and Construction

To help achieve this goal, The City of Calgary requires minimum energy consumption and energy cost improvements above an NECB 2011 baseline building for their projects. LEED’s Energy and Atmosphere credit category provides a framework to help The City achieve this goal. The City of Calgary utilized this credit Organics Waste Diversion Facility – Administration & Education (A&E)

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.

OCH Carlington Hub Passive House the most cost effective for seniors housing and health centre By Stephen Pope and Marc Mainville
1
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.
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.”

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
