A refreshed start for 2022 A message from Canada Green Building Council president and CEO, Thomas Mueller 21

It is with great pleasure that I welcome you to the Spring issue of FOCUS BC, a long-standing partnership between CAGBC and Sustainable Architecture & Building Magazine. As we enter the Council’s 20th anniversary year, we remember and value our past and current relationships.

Relationships were critical in moving CAGBC’s agenda forward, despite the challenges of the pandemic. By working together, we have made significant progress. Over the last year, we saw unprecedented interest from industry and policy-makers in green building as a solution to climate change, resiliency, health and safety. The acceptance of climate change has driven the widespread adoption of ESG (Environment, Social, Governance) frameworks among Canadian corporations and the global announcements at COP26 led to an unprecedented commitment to climate action.

We saw this commitment reflected in the federal Ministers’ mandate letters which address CAGBC’s recommendations to increase funding opportunities for zero carbon green buildings.

It also drove more market interest in CAGBC services, research and products, including LEED, the Zero Carbon Building Standards, and Investor Ready Energy Efficiency certification for retrofits.

Closer to home, B.C. continues to be a leader in green building, with aggressive commitments to reduce carbon emissions by 2030. Vancouver was recently named the Most Sustainable City in North America, and the Vancouver Plan for a more livable, sustainable, and affordable city is in its final stages.

Green buildings will play a major role in the city and the province’s efforts to lower carbon emissions and improve community resiliency. In this issue, SAB Mag highlights some exciting B.C. projects such as The Minoru Centre for Active Living, The Black Barn Project, and the South Haven Centre for Remembrance.

Having just returned from Building Lasting Change, the green building sector’s annual conference, I have reason to be optimistic about the future.

Canada remains a leader in LEED certified space globally, and interest in our Zero Carbon Building standards continues to grow, with the recent launch of version three of the Zero Carbon Building – Design Standard. From BLC’s focus on carbon reductions, our latest reports Decarbonizing Canada’s Large Buildings and Canadian Green Retrofit Economy Study, we are helping the sector find new pathways to zero carbon. I hope you’ll enjoy this issue as much as I have.

Sincerely, Thomas Mueller President & CEO, Canada Green Building Council

GREENING CANADA’S BUILDINGS WILL CREATE 75,000 JOBS ANNUALLY The Canada Green Building Council (CAGBC) and The Delphi Group recently outlined how Canada can benefit from a vibrant and growing retrofit economy with the launch of the Canadian Green Retrofit Economy Study. Through green retrofits, Canada’s buildings can contribute to net-zero climate targets, make buildings more resilient to climate change and extreme weather events, and provide rewarding job opportunities while strengthening the domestic supply of low-carbon products and services.

“Canada’s building sector must be able to meet demand in the right locations and at the right time to capitalize on the green retrofits opportunity,” said Ben Clark, co-author of the report and Director, Green Economy with Delphi. “Ensuring there are enough skilled workers to accommodate growing retrofit projects as well as an accessible and affordable supply — including the products, materials, and technologies needed to service the retrofit economy — will be critical.”

Unveiled at Building Lasting Change, Canada’s premier green building conference, the study demonstrates that green retrofits that lower the carbon footprint of buildings have the potential to generate up to 2.1 million job years and help Canada meet its 2030 and 2050 climate targets.

The report anticipates that Canada will see a shortage of skilled workers in the near term, even without an increase in retrofit projects. These include carpenters, HVAC trades, plasterers and drywall installers, and mechanical engineers and technicians.

“Governments, employers, and educators must be focused on reskilling existing workers and growing the workforce

by removing the stigma associated with trades and reaching underrepresented groups,” said Thomas Mueller, CAGBC President and CEO. “We need to think ahead to ensure we have the right resources and supports in place as retrofit activity accelerates in the face of the rising cost of carbon.”

The report identifies the importance of enhancing expertise and knowledge across the retrofit spectrum, including among decisionmakers, designers, financing experts and consultants, where efforts can address the complexity and capital constraints associated with investment.

Investments in a robust, accessible, and an affordable supply chain are also needed to drive innovation and secure access to the products and services needed to complete green retrofits at scale. The report identified more than 25 technologies and products that are directly relevant to low-carbon retrofits, including building automation systems, heat pumps, heat and energy recovery systems, wall recladding systems, thermal bridging technology and integrated photovoltaics.

“Canada already has many of the technologies needed to accelerate retrofits at scale,” said Ehren Cory, CEO of the Canada Infrastructure Bank. “This study offers insights into where stakeholders need to collaborate and focus to remove barriers to retrofits and, in the process, modernize Canada’s built environment and meet its climate targets. It is essential reading for the new retrofit economy.”

The Canadian Green Retrofit Economy Study is available at cagbc. org/retrofit-economy. This report was made possible with support from the Canada Infrastructure Bank (CIB), the Ontario Construction Secretariat, the Federation of Canadian Municipalities, and Canada Mortgage and Housing Corporation (CMHC).

CAGBC’S ZERO CARBON BUILDING – DESIGN STANDARD TO PHASE OUT COMBUSTION New version incentivizes efficiency, alternatives to fossil fuels The Canada Green Building Council (CAGBC) recently introduced the latest version of its Zero Carbon Building – Design Standard, demonstrating a continued commitment to getting more buildings to zero faster.

The ZCB-Design v3 Standard prioritizes reductions in carbon emissions and embodied carbon, and energy-efficient design that promotes good grid citizenship.

“These updates to the ZCB-Design Standard are informed by two years of market and project feedback, as well as changing market expectations of operational and embodied carbon emissions,” said Thomas Mueller, President and CEO of CAGBC. “Our research shows that the industry needs flexibility in achieving zero carbon. That’s what our standard provides without compromising our target to eliminate carbon emissions from buildings.”

SUMMER 2022 | BC FOCUS

Phasing out combustion for significant carbon reductions ZCB-Design v3 offers additional thermal energy demand intensity (TEDI) flexibility to incentivize projects to move away from combustion. Projects that eliminate combustion for space heating are no longer required to meet a TEDI target. Now design teams can optimize their building enclosures and HVAC design for the best possible returns.

“This change gives projects the freedom to invest project dollars to achieve the greatest impact at the lowest cost,” said Mark Hutchinson, Vice President of Green Building Programs and Innovation at CAGBC. “For example, projects might choose to invest in a geo-exchange system and completely electrify, rather than invest in additional envelope efficiency but still use air-source heat pumps and backup natural gas.”

ZCB-Design v3 also puts a limit on combustion, preventing it from being used unless the outdoor air temperature is below -10 C. This change ensures electrification of heating is the new default, only stopping at the point of system limitation.

Today, all heat pump applications have options available to -10 C, while some go as low as -30 C. By choosing -10 C, the Standard doesn’t prescribe a solution but makes substantial electrification a requirement.

Putting a limit on embodied carbon The Standard introduces a prerequisite for embodied carbon, with the flexibility to choose between absolute embodied carbon targets or relative improvements over a baseline.

The new limit is a critical next step towards CAGBC’s goal of reducing embodied carbon 40% by 2030. CAGBC’s Embodied Carbon: A Primer for Buildings in Canada calculated that embodied carbon could represent as much as 93 percent of a new building’s cumulative emissions in 2050.

Sticks to Concrete Without Primer

Zero carbon momentum Collectively, the changes are particularly helpful for smaller buildings and multi-unit residential projects. The changes were guided by the Zero Carbon Steering Committee, supported by an Embodied Carbon Working Group and CAGBC’s Energy and Engineering Technical Advisory Group. Already, CAGBC is seeing increased interest in this new iteration.

“These changes were designed with an eye to the simplicity and accessibility of the Standard and a clear focus on driving carbon reductions,” said Doug Webber, Chair of the Zero Carbon Steering Committee and Co-Founder and Principal of Purpose Building. “The intent is to reduce the cost and effort required to achieve the desired outcomes of certification, and to open the Standard to as many projects as possible. I know the changes will remove barriers that some of our clients were facing,” The market has shown it is ready for the transition. This month, CAGBC celebrated the 50th building certification under the Zero Carbon Building standards. Across Canada, jurisdictions like Vancouver, Toronto and Montreal are implementing aggressive plans to reduce carbon emissions from buildings, and the private sector’s efforts are equally ambitious.

Increasingly, projects are using CAGBC’s standards to help map out their approach to decarbonization.

Fentrim® 430 grey

If Canada is to meet its climate targets, every building must be a zero-carbon building. Balancing rigour with flexibility is one way the ZCB standards encourage the transition to zero.

A strong business case also helps. CAGBC proved new zero carbon buildings were technically feasible and financially viable with the seminal report Making the Case for Zero Carbon Building. Most recently, CAGBC tackled zero-carbon retrofits with Decarbonizing Canada’s Large Buildings, and demonstrated that every building has a path to zero. As the cost of carbon and the risks of climate change grow, the value of zero-carbon buildings will only increase.

THE BLACK BARN PROJECT A re-envisioning employs passive ideas and prefabrication

By Ralph Herzig The Black Barn project on Salt Spring Island, BC was conceived as a prototype for energy-efficient, prefabricated custom homes in remote locations around the province.

Historically, Salt Spring Island provided food for Victoria and Lower Mainland Vancouver for close to 150 years. Known as the “fruit basket” of the islands, Salt Spring farms supplied large quantities of fruit and vegetables. Old apple orchards still dot the island and contain long lost varieties.

SUMMER 2022 | BC FOCUS

The typology of a typical barn building traces its roots to the oldest homestead found in Ruckle Provincial Park on the south end of the Island, which is still a working farm. The island’s agricultural history provided the “patina” and backdrop to the 160 m2, two-bedroom, two-bathroom holiday home that could serve as a temporary or permanent home to its owners.

Careful studies of the sunlight conditions were made to select the site but also orient the building to optimize sunshine exposure throughout the year. While many locations on the site provide outstanding views, the one selected receives four hours of direct sunlight during the shortest day of the year.

The building is located at an existing roughed-in building site that was completely overgrown. During the site preparation 20 truckloads of quarried stone were discovered, left there from earlier times. Half of the stones were used in new retaining walls and the rest traded for excavation work to be re-used on other construction sites.

An HRV system delivers 0.5 air cycles/hour and includes HEPA filters that can remove smoke particulates. When the house was first occupied (late summer 2020), the HRV system noticeably improved indoor air quality compared to the outside air affected by forest fires along the west coast of the continent.

4. The narrow footprint allows plenty of natural light throughout the interior. 5. HVAC efficiencies are achieved with the in-floor warm air radiant heating system, an energy recovery ventilator, and with a Rheem Marathon water heater having a highly insulated non-metallic tank which minimizes standby heat loss. 6. The master bathroom on the second-floor loft where a skylight admits additional natural light.

An important aspect of the building design was the choice of materials and finishes used. For example, the interior was painted using low-VOC Farrow and Ball paint. Wood stains and oils to finish wood elements included Osmo oils.

The Douglas fir flooring on stairs and mezzanine areas was treated with lye and white oil which allow the wood to breath and is water repellent. This surface can be washed with a natural, water-based soap solution.

Floor-to-ceiling windows blur the boundaries between inside and out, and the building layout would allow the owners to occupy the ground floor if needed as they age. The lower floor bedroom and bathroom, with a low threshold walk-in shower, facilitate usability over multiple stages of life.

Passive heating principles include south-facing openings designed to maximize sunlight penetration in winter and reduce solar gain during the summer months. The significant thermal mass of the slab on grade foundation contributes to the moderation of temperature swings. Moreover, the slab contains an in-floor warm air heating system which, in effect, makes the slab act as heat battery with a slow, even release of heat.

The prefabricated wall and roof panels and service wall assemblies provide R values of 32 and 47, respectively, while the floor assembly is rated at R 34. The total energy consumption is 80 kWh/m2/year.

The primary energy source for the building is electricity. The building utilizes LED lighting and provides natural light for all work areas thereby reducing the energy consumption needed for work and living.

The anticipated installation of a grid-tied PV plant is supported by pre-installed conduits. Additional conduits have also been installed to allow for an electrical charging station. These anticipated next phase investments support the Salt Spring Island Climate Action plan and priorities.

The design-build strategy involved the use of several pre-fabricated building elements including: insulated wall and roof panels, floor elements, ICF foundation elements and pre-stained and cut exterior façade elements. The selection of these pre-fabricated components reduced the onsite installation time and also significantly reduced waste and the excess shipping of material to and from the island, an observation that did not go unnoticed by inspectors and installers.

Wherever possible, onsite waste, such as packaging materials, was returned to the community recycling facility.

From a material perspective the building used materials with an inherent longer service life and lower lifetime service needs. For example, the use of a metal roof instead of asphalt shingles; hardwearing polished concrete flooring; and factory-applied wood penetrating stain with longer repaint cycle quality will result in less maintenance and replacement over time.

THE MINORU CENTRE FOR ACTIVE LIVING LEED Gold building with flowing roof a new amenity for community wellbeing

By Michael Henderson Located in Richmond’s city centre, the Minoru Centre for Active Living replaces three existing facilities and acts as a gateway to the 105-year-old Minoru Park. It includes a 69,000 square foot aquatic centre focused on health and wellness, a seniors community centre, a fitness centre, athletic team rooms, social lobby with food service, event spaces and an outdoor community plaza.

18

SUMMER 2022 | BC FOCUS

The Minoru Centre for Active Living plays a pivotal urban role in shaping and bookending the Granville Avenue civic precinct, reconnecting this key street to Minoru Park. As we examined the site in relation to the program requirements it became evident that pedestrian linkages into the park and other existing facilities would be vital to the success of the project. Additional strategic decisions resulted in the following: • Orientation of program and substantial overhangs to protect the pool from east-west sun angles causing most difficult to control glare and heat gain,

2 2. The curtainwall system provides significant access to natural daylight, while thermally-broken overhangs protect the natatorium space from solar heat gain. 3. The west entrance and covered pool patio.

• Natural daylighting and opportunities for passive ventilation through glazing and skylights, and • Substantial green and permeable site area including views to greenspace and biophilia.

The existing high-water table and geotechnical conditions found throughout Richmond required that the pool tanks be located above the high ground water table. To address this without excessive grade change, which would impede accessibility to the building, the design introduced a terracing pool deck which gradually raises toward the north where the deepest pool is located.

The result is a building and natatorium with several floor levels with the added benefit of beautiful cascading infinity pool design.

The terraced pool design also allowed for a functional accessibility and inclusivity innovation: the infinity edge. By creating the option for individuals to transfer out of chairs into the water, the design extends the range of abilities that can access the pools with dignity. The result is a place where a diverse and intergenerational community has the opportunity to mix and inter-relate, supporting lifelong learning goals and wellness for everyone.

The flowing roof structure strategically introduces natural daylight deep into building areas while substantial curtainwall facades bring light into spaces throughout the facility. This design was guided by advanced daylighting modelling that allowed hour by hour and seasonal analysis of daylighting benefits. Large canopies provide shade protection for solar gain on exposed facades. Artificial lighting throughout the facility is LED controlled by occupancy sensors.

The building is ventilated with a combination of air heat recovery and mixed air handlers with exhausted air heat recovery. The design air change rates for major spaces are summarized as follows: Natatorium and Change rooms at 6 AC/hr; Fitness Centre at 3-4 AC/hr; and all other spaces at 2-3 AC/hr. All ventilation is controlled

by CO2 measurement as demand control ventilation.

The large windows frame views of the outdoor spaces which are both active and passive green spaces and plazas providing a direct connection to nature, daylight and biodiversity. Throughout the Covid-19 pandemic the substantial covered outdoor spaces surrounding the building have acted as informal gathering space as well as spaces for physical fitness programs such as Tai Chi, aerobics and dance classes.

PROJECT CREDITS Client: City of Richmond Architect: hcma Construction: Stuart Olson (now Bird Construction) Structural engineer: Fast & Epp Mechanical engineer: AME Group

The facility is designed to reduce water consumption by over 39% from a LEED base building. This conservation is made through low-flow plumbing fixtures, efficient pool filtration systems and the use of greywater for landscape irrigation.

Waste water from hot pools, which have a higher turnover rate due to pool temperature, is cleaned using the pool disinfection and filtration system before being stored in an exterior, below grade cistern. This cistern acts as a reserve for 100% of site landscape irrigation thereby reducing the civic infrastructure burden and saving valuable potable water resources. This water source is of particular benefit in dry summer months when water restrictions are often implemented in the region.

In addition to reducing energy intensity by more than 48% (as compared to MNECB base building) to 603.6 KWhr/m2, the LEED Gold building employs several strategies that improve efficiencies: • Combining aquatic programs with seniors programs in one facility reduces duplication of services and allows for greater utilization rates of almost every program component while reducing the associated auxiliary components (mechanical, support and staff areas).

6 • Site orientation and substantial thermally-broken building overhangs protect the natatorium space from unwanted solar heat gain.

• A well performing curtainwall system provides significant access to natural daylight throughout the facility.

The Minoru Centre is symbolized by its expressive roof form that spans and unifies the rational program components. The roof consists of a hybrid steel and locally-manufactured glulam portal system capable of spanning up to 40 metres in some sections of the natatorium.

This investment in a roof structure that utilizes heavy timber plays a significant role in the reduction of embodied carbon for the facility. Further, 87% of the total wood installed onsite has been certified FSC ensuring that the timber has been managed and harvested according to social, economic and environmental standards. More than 77% of construction materials were diverted from landfill and 24% of materials were regionally sourced.

The project is a symbol of the community’s vision for holistic health, wellbeing and sustainability, and has helped reaffirm the role of Minoru Park as a valuable public amenity for hosting cultural and sporting events, family gatherings, and bustling farmers’ markets.

2 1. and 2. The unique nature of the building typology and the opportunity to evaluate and position a new structure in relationship to a vast 21-hectare cemetery site required layers of analysis and consideration.

One of the fundamental goals was to position the building in a prominent central location which effectively orients visitors and provides a new focal point for the site. The new building has been carefully positioned to provide occupants with a frame of reference which visually connects them to the natural prairie landscape, capturing distant views to the Edmonton skyline beyond, and responding to the expansive cemetery scale and open landscape.

The design team focused on creating a structure which becomes part building and part landscape, which also informed the strategy to connect the perimeter retaining wall of the works yard to the exterior face of the building. By joining the functional building program components with the visual screen required for the operational yard, the building emerges as a unified element which works its way through the prairie landscape.

The single mono-pitch roof culminates in the tower at the northwest corner of the centralized courtyard. A north-facing clerestory in the tower allows diffuse light to enter the family rooms.

The landscape design reflects the architecture of the building, picking up on building alignments and angles and extending these lines into the landscape, tying the building in with the surroundings and making it part of the cemetery. Simple but effective elements include loose tree coverage, areas of manicured/mowed grass and areas with taller, native prairie grass.

A central open-air courtyard provides additional flexible gathe­ring space for the public and staff to enjoy during the spring, summer and fall. During the winter, the west-facing courtyard is protected from prevailing winds and allows light to penetrate the interior. A combination of translucent and vision glass is used in combination to provide framed views to the city skyline beyond as well as allowing mediated diffuse light to enter the primary lobby and corridor spaces.

4. Much of the interior has a light, luminous effect.

With no services to the site except power, priority was placed on conservation and building performance. Managing storm water run-off and minimizing water demand goes alongside the high-performance envelope system and tailored mechanical system which reduce the overall energy demand.

Moreover, the building’s compact form, nestled into the landscape, further aids energy conservation as will landscape berms made from excavated fill around the perimeter of the building to act as a natural wind breaks.

shadows that are cast by the building. The reflection from snow cover and the changing relationship of the building in the landscape throughout the year were taken into account.

Exterior cladding of black hot rolled steel panels and black charred shou sugi-ban cedar acts as a counterpoint to a snowy landscape. Winter-bare trembling aspen trees also contrast starkly with the building skin.

The main entrance sequence is predominated by hot rolled steel walls which allow for a compressed moment of darkness prior to opening the oversized steel pivot doors to the light luminous interior and the focused view of the city.
