FALL 2020 Toronto FOCUS
WELCOME TO TORONTO FOCUS
We are pleased to share with you this twentieth Toronto FOCUS supplement produced in partnership with SABMag.
December marks the release of CaGBC’s 2020 Canadian Green Building Market Impact report. Ontario continues to lead the country with over 430,000 green building jobs - from design, to construction, to operations, suppliers, researchers, and regulators. This represents over $43 Billion in GDP. The focus on climate change and “green recovery” from COVID has the potential to significantly increase the size of the green building sector by 200,000 workers by 2030 with particularly strong growth in the retrofit market. Projects like Scotia Plaza, which demonstrates how existing buildings can achieve Zero Carbon, will need significant scale-up. On the other hand, we have a lot of work to do to attract, retain, and upskill the workforce if we are to fill these jobs, deal with the aging workforce and reverse social trends that discourage young people from entering the sector. This will be a major focus for us moving forward, including our leadership with the Workforce 2030 Coalition, which is uniting diverse stakeholders to accelerate workforce capacity building for low-carbon buildings in Ontario. We will all remember 2020 for its challenges, but I’m encouraged that our industry can lead the recovery efforts and leave us all better off on the other side.

Humber College Barrett Centre for Technology Innovation Net Zero building centres on wellness, durability and open-concept teaching By Duff Balmer, Principal, Perkins&Will The Barrett Centre for Technology Innovation (BCTI)— the first Net Zero Energy building for Humber College and registered to achieve LEED Platinum certification— is a flagship building for the campus. The facility sets a new stage at post-secondary institutions for innovation in automated manufacturing and human-centered solutions for the 21st Century by omitting classrooms entirely. The campus master plan was analyzed for site locations considering efficient use of space with shared resources including parking and services like the district energy central plant. Parametric design analysis, including solar and radiation, wind and daylighting penetration, optimized both the massing and envelope resulting in a highly insulated façade and concrete floors acting as thermal mass in the lobby. A protected bus terminal outside of the building, which will link to future light-rail transit, makes the BCTI a well-connected magnet for students, community, and industry partners to gather, collaborate and showcase projects. The building presents itself as a dramatic portal through its dynamic prismatic glazed lobby and gravity defying cantilevered form establishing a new focal point for student life.
1. A mix of cladding was used on the project. CBC Specialty Metals is proud to have supplied Bothwell-Accurate Co. Inc with the VM Zinc Anthra Strat Interlocking Panels, having expected lifespan of over 100 years for the Humber College Barrett Centre. Also, fire-safe premium aluminum architectural products by Longboard Products for interior and exterior solutions were used for ease of installation and creative façade possibilities.

The BCTI is seamlessly interlinked with the surrounding network of campus open spaces and delivers street level appeal. It addresses the urban heat island effect by maximizing green space at grade and incorporating a vegetated roof. Planted areas use native and drought-resistant species eliminating need for irrigation and creating habitats for micro-ecosystems that contribute to the greater local ecosystem supporting habitat and promoting biodiversity. Taking a conservation-first approach, a parametric analysis was made prior to making active mechanical and electrical system decisions. A moderate glazing-to-wall ratio of 40% focuses glazing on where daylight is needed most in occupied areas. Brise Soleil shading devices on the south façade mitigate heat gain and glare. Efficiency measures include: 96% efficient condensing style boilers serving DHW and service heating loop; dedicated outside air system for accurate/efficient fresh air; air handling system with energy recovery enthalpy wheels from relief/exhaust air to temper outside air and reduce energy; and a cooling system with distributed fan coil units to cut cooling transmission energy use with hydronic systems instead of central air systems. 2. The roof is partly vegetated to contribute to stormwater retention. Around the building exterior the ACO KlassikDrain handles stormwater collection in the form of an aesthetically pleasing linear trench drain which helps to maintain smooth surface grading while preserving building accessibility. With proven performance in winter conditions, it also provides LEED credit eligibility for regional manufacturing. Noram’s high-performance unitized curtain wall, oversized glass, high span, sunshades and remote-powered operated vents contribute to the bold technological and visual sophistication of the building’s commitment to sustainability.

Omitting traditional classrooms, the facility has interactive demonstration areas and flexible open-concept gathering spaces intended to inspire an informal and active learning experience. Biophilic design strategies are the essence of spaces like the central atrium offering an immediate connection to the outdoors through views to surrounding landscaped spaces and campus at large and ample access to natural light. The atrium also assists natural ventilation which is tied to CO2 monitoring to improve indoor air quality and limit energy consumption The project achieved the requirements of LEED indoor chemical and pollutant source control, including the installation of MERV 13 filtration prior to occupancy to improve air quality. Low-emitting materials were selected to exceed LEED prescribed requirements. For example, 20 finishes were screened against a list of 53 precautionary chemicals known to have negative effect on both human health and the environment. The BCTI is a Net Zero Energy building, with its entire energy use offset by the 700 kW solar PV array located on the adjacent parking structure. A series of passive studies and strategies have been employed including a solar chimney which allows natural ventilation in the more temperate seasons, a passive house inspired building envelope with enhanced R-values and reduced thermal bridging, and extensive natural daylighting in occupied areas. Passive strategies are complemented with high-efficiency active lighting, heating, and cooling systems which result in the BCTI being one of the most energy efficient buildings of its type in Ontario with a designed EUI of 99.82 kWh/sq.m. 12

This aligns with Humber College’s long-term Integrated Energy and Water Master Plan which mandates that all buildings perform at or near best practices for energy efficiency at 100 kWh/m2 or lower. When considering the envelope, the design team adjusted various parameters including R-value, infiltration rates, and solar heat gain coefficients for glazing using dynamic multi-parametric modelling software to find the most efficient and cost-effective combination of elements. A dark natural zinc plank system was chosen as cladding for its durability and modularity, allowing greater ease of long-term maintenance. Durable, natural limestone along the base of the building provides a direct material linkage to the surrounding natural landscape. Resilience analysis was conducted for future weather data and impact on building cooling and heating degree days, as well as climate impact on exterior materials. A durability plan was developed with a durability consultant to ensure decisions aligned with the building’s service life. Interior spaces are modular and demountable, and operable wall systems allow spaces to be converted and expanded over time. Flexibility is considered at a systems level with fully exposed and accessible HVAC and electrical for ease of reconfiguration.
3. The building’s success is bolstered by the high visibility of its spaces with areas for students and industry which encourage community interaction. Lochinvar by Aqua-Tech supplied two Crest Condensing Boilers Model FBN1751 for space heating and domestic hot water, and a GVC65JR Hot Water Generator c/w Double Wall Tube Bundle for indirect domestic hot water demand.

Strategic placement of the building was key to ensuring Canon’s vision for a “building within a park”. Building shape, glazing area, depth of floor plate, and location of regularly occupied spaces within the building were designed to maximize access to the more than 18 acres of landscaped terrain. 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. With the long narrow site running north-south, the building was designed with longer glazed facades on the east and west. The carefully detailed vertical glass fins integrated into the exterior glazing assembly is a prominent feature and reflects Canon’s world renown precision lens making, while providing solar shading, reducing indoor solar heat gain and glare. The south and north facades are mainly solid to avoid heat gain in the interior spaces. Daylighting was analyzed for March 21st at both 9 a.m. and 3 p.m., as per LEED requirements. The adjusted minimum threshold of 108 lux was used as per CIR 934. Overall, 87% of occupied areas meet this daylight threshold.

The underfloor air distribution system through the raised floor facilitates individual control of airflow through floor vents located near workstations so that occupants may adjust the airflow to suit their comfort needs. Thermostats with +/2 degrees temperature control are also supplied in meeting rooms and other multioccupant spaces The building’s 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. A variety of work environments, ergonomic furniture, interior plantings, individually-controlled lighting, and low-VOC materials further enhance staff well-being. A fitness centre and reflection room promote physical well-being, and a full-service cafeteria provides staff with healthy in-house eating options. Rainwater is collected, filtered and stored in an underground cistern. Once the rainwater is filtered and becomes available for use, the domestic city water use is automatically shut off and the building begins to use the rainwater for flushing and irrigation. The use of native and drought-resistant plants, rainwater reuse as noted, and low-flow fixtures together reduce water use by 55% compared to a baseline. A highly sophisticated building automation system controls the indoor climate, under-floor air distribution, lighting systems, window blinds, A/V and security systems in a way that is highly energy efficient, while providing the optimized comfort for all staff.

Site Section
Occupancy light sensors are a key part of a low-energy lighting design. The placement of desks and offices allows maximum light throughout the facility, reducing the amount of energy required for lighting. Triple-glazed windows and highly insulated walls and roofs are used to improve energy performance. A free cooling heat exchanger is used to assist in chilling water, which can then be used for air conditioning. This method helps to reduce greenhouse gas emissions and energy consumption. A measurement and verification plan will provide ongoing accountability of building energy consumption over time. Biophilic design increases connectivity of occupants to the natural environment with the use of natural light and natural materials such as travertine stone, granite, wood, and plants. A minimum of 50% of the hardscape consists of high-albedo paving with a minimum SRI value of 29 (such as white concrete). Reflective, white roofing materials are specified for roof for heat island reduction. Low-emitting materials such as adhesives and sealants, flooring systems, composite wood, etc were used.

Waste Management and Education Centre Net zero rammed earth building a public resource By Michael A. Wilson In 2015, the County of Oxford established two key strategic goals of becoming a Zero Waste community by the year 2025, and a 100% Renewable Energy community by the year 2050.
BUILDING STATISTICS: GFA: 372 sq. m. R-values: under floor 24, walls and roof 55, windows 9. HVAC: electric 2 air to air heat pumps, with ERVs – under floor supply air. Site: Net Zero PV size of 120kWAC, with 24kWAC being required to Net-Zero the administration building only. 1. The Net Zero project program and budget allowed the energy needs for both the new building and all site buildings and facilities to be met by a ground-mounted solar photovoltaic array. 2. The compact, nearly square building volume reduces wall surface area and admits natural light from all sides through a clearstorey. 2

The new building for the Oxford County Waste Management Facility replaces the original administrative office, and now also includes a regional conference room and displays about waste management and conservation for public education and school field trips. The project energy goals include the provision of a comfortable building that consumes very low amounts of energy during operation by implementing strategies and technologies of typical Passive House projects. The Net Zero project program and budget allowed the energy needs for both the new building and all existing site buildings and facilities to be met by a ground-mounted solar photovoltaic array situated along the access driveway in public view.

The building also has a high efficiency central ERV system, built in Canada by Tempeff, which acts as the building’s lungs. An ERV not only recovers heat, but also factors in humidity making it the best choice for occupant comfort in a cold, humid climate. Tempeff’s ERV makes use of Dual-Core technology allowing for continuous fresh air supply and frost-free operation in this climate.

The compact, nearly square building volume reduces wall surface area and admits natural light from all sides through a clearstory for privacy in the locker room on the east and north, and operable windows at the south and west. The white ceilings and interior demising walls reflect the natural light sufficiently to negate the need of the energy-efficient lighting systems for much of the time. Though still uncommon in Ontario, rammed earth construction, also known as “site-placed concrete”, was proposed to the owner early in the design process as an appropriate system for a building on a landfill site. Its method of construction, in which the walls are formed as pigmented layers in compacted lifts, make a reference to the layered nature of a landfill site. The rammed earth wall consists of an interior loadbearing wythe of 200 mm, a 200 mm layer of insulation, and an external wythe of 150 mm. Though the minimum design bearing capacity required was 10MPA, with the high lime content of the vernacular granular used, 24MPA was achieved at 28 days. The thermal mass of the walls keeps the interior humidity and temperature extremely consistent and comfortable.

The painted triple-pane wood windows are made from the resilient Accoya® wood and are protected by the roof overhang which also reduces solar gain. The gentle slope of the roof is adequate to prevent ponding to extend the life of the roof membrane. The building performance will be measured against the New Building Institute’s (NBI) Zero Net Energy criteria (71.5 kWh/m2) with a goal of demonstrating that the building achieves Net-Zero performance over a 12-month period. If the building meets this target it will be one of the first buildings in the country to be verified as a Zero Net Energy building by the NBI. Educating the public is as important a function of the building as providing new space for administration and operations staff. Outfitted with interactive educational displays about recycling materials, energy reduction methods and landfill technology, the building is a destination for school children. Broken glass and even some of the architect’s personal fossil collection have been visibly placed within the polished concrete floor, and a reclaimed barn beam in the feature wall display promotes the idea of repurposing building materials. Real time energy consumption displayed on a computer monitor within the main room of the education centre shows visitors the peak energy consumption periods during the day.

Fast-tracking the workforce for a low-carbon Canada By Juliana Dutkay, Workforce 2030 Coalition Lead During one of the Building Lasting Change 2020 Online sessions on September 22, industry leaders came together to discuss the need to upskill building sector workers to meet the demand of low-carbon construction and retrofits. A robust workforce is key to carbon reduction targets in the building sector. Financing, supply chains and scaling proven and available technologies are also critical, but especially for the construction industry, workforce is top of mind both in terms of numbers and skills. With a ‘retirement bubble’ accounting for almost quarter of the construction labour force, the industry needs to look at a full spectrum of solutions from aggressive recruitment on the domestic side, to workforce mobility and immigration policy to bring in permanent skilled workers, said Bill Ferreira, executive director of BuildForce Canada. “You cannot flip a switch and suddenly add more people,” said Ferreira. “It takes about four years to train apprentices and develop skills. The industry needs time to adjust to that.” Despite the pandemic, growth in the building sector remains strong. Demand for labour remains especially high in British Columbia and Ontario. At Ellis Don, construction projects are in full swing and backlog continues to grow. “We are seeing a significant focus on sustainability, technology and smart buildings,” said Clare Ashbee, vice president of Sustainable Buildings at Ellis Don. “It is increasing at an exponential rate, while we all experience a constraint construction labour market.” With significant investment in modular construction, Ellis Don is feeling the labour crunch. “We need to hire 100 people in our modular building division by December. That is a huge amount of people,” said Ashbee. “We need engineers knowledgeable in building envelope and materials.”
Training for low-carbon While baseline skills for low-carbon building are not dramatically different from conventional buildings, some upskilling is required. Strong communication and collaboration across disciplines, an integrated design-build approach, and strong quality assurance skills are also necessary to achieve carbon reduction and energy performance.

FALL 2020 Toronto FOCUS
Building operation and facilities management are also crucial, as people need to be trained so the systems and new technologies in a low-carbon building reach optimal performance. To ensure that the construction workforce is ready for more low-carbon buildings, the sector needs to pivot toward life-long learning and adaptability, and nurture social and emotional skills, according to Pedro Barata, executive director of Future Skills Centre. Economic recovery and job creation are a priority for all levels of government. Infrastructure investments are a staple of stimulus and skills development will need to be part of the package. While Canada is a world leader when it comes to education, but it is not yet equipped for the emerging low-carbon economy.
“The industry needs to set benchmarks, targets and KPIs to make meaningful progress on diversifying the construction workforce, just as it does to advance any other business priority,” said Barata. Equity and Inclusion Construction is a huge sector of the economy with roughly one in 13 Canadians working in construction, according to Buildforce research. It can provide good, wellpaying jobs. But who has access to them? As part of a coalition to drive workforce engagement, growth of the workforce is as important as upskilling, and attention is being paid to ensure that diversity and inclusion are part of the growth strategy. “The construction industry must address underrepresented groups such as women, racialized people, youth and people with disabilities,” said Jeff Ranson, regional director CaGBC’s Greater Toronto Chapter. “This is critical to the sectors future growth and to address the social inequality that has only been depended by the pandemic.”
Zero carbon building reaches new heights with first ZCB-Performance v2 certification Scotia Plaza’s 40 King St. W. is a commercial high-rise located in the heart of Toronto’s financial district. In June 2020, it became the largest zero carbon building in Canada, and the first to certify under Zero Carbon Building – Performance (ZCB-Performance) v2.
Designed by WZMH Architects and completed in 1988, Scotia Plaza’s 40 King St. W. features 68 storeys of above-grade AAA Class commercial office space, and below-grade, one level of retail and four levels of parking. The building is a concrete frame, clad with distinctive granite claddings and punched window openings with double-glazed, aluminum-framed windows that make the building stand out in the Toronto skyline.
Accelerating to zero in Toronto’s financial core Scotia Plaza’s 40 King St. W. is recognized as one of the first major office towers in Canada to achieve LEED Platinum certification. As a premium location in the heart of the financial district, it was important to the building owners, KingSett Capital, Alberta Investment Management Corporation (AIMCo), and James Richardson & Sons Limited (JSRL), that the building maintain the highest operating standards. “The path to becoming a zero carbon building started by making the necessary building and operational enhancements to achieve LEED Platinum, which was an integral step in being able to achieve the Zero Carbon Building certification,” said Bill Logar, EVP of Asset Management at KingSett Capital. “This achievement makes 40 King St. W. a healthier, more sustainable, and all-around more environmentally sound workplace.”
“The transition to a carbon-neutral portfolio requires thoughtful long-term planning. We are making investments today that will have a positive impact on climate change now and in the future, such as pursing the Zero Carbon Building Standard.” - Bill Logar, EVP, Asset Management, KingSett Capital Photos courtesy KingSett Capital.

“A sophisticated metering system enables the tracking of energy consumption and early identification of potential anomalies at the property,” said David Matarasso, Principal, Property Management at BentallGreenOak. “Together, these serve as a system of internal controls which support the operations teams and drives performance at the building.”

Consideration was also given to the HVAC equipment containing refrigerants, in keeping with the updates to ZCB Standard v2. The LEED certification at the building already required proper refrigerant management, including detailed maintenance and record-keeping procedures. ZCB-Performance certification required that the owners take a step further, reporting and offsetting all refrigerant leakage.
Always looking ahead KingSett invests in sustainable and innovative solutions that go beyond the building to enhance communities, mitigate risk, and reduce environmental impact – including reducing greenhouse gas (GHG) emissions. KingSett is committed to developing asset-specific carbon neutrality roadmaps for its assets. Having achieved LEED Platinum, Fitwel, and WiredScore certification at 40 King St. W., tackling GHG emissions using the Zero Carbon Building (ZCB) Standard was a natural next step. Achieving and maintaining these high standards is critical for the overall environmental, social, governance and resilience performance of the building.
Prioritizing carbon reductions The pursuit of the ZCB Standard meant taking a close look at energy requirements. Both grid electricity and utility-supplied natural gas are consumed at 40 King St. W. The building benefits from the fact that central heating is electric, not typical of large towers. Property management team, BentallGreenOak, leverages 40 King St. W.’s robust metering and energy monitoring system to record and drive decision making from real-time interval consumption data. This level of detail allows for a comparison of current energy consumption against energy budget estimates, real-time variations in energy use and fast detection of anomalies.

FALL 2020 Toronto FOCUS
As part of the ZCB certification, a carbon transition plan was established to help move the building away from the limited number of systems using fuel combustion. Four systems historically used combustion-based technology: main building humidification, parking garage heating, loading dock heating, and concourse restaurants. Working with a team of consultants at Purpose Building Inc., the owners are rapidly transitioning away from fossil fuel combustion for all base building systems. The remaining fossil fuel combustion will be limited to the restaurant tenants and their cooking equipment. Thanks to the building’s original design, reliance on limited combustion-based systems, and diligent ongoing performance monitoring, this 68-storey building had a total carbon footprint of only 1,561 metric tonnes of carbon dioxide equivalent. Going above and beyond, KingSett chose to assess and offset emissions associated with the waste from the building, which contributed a further 1,194 metric tonnes. Carbon offsets were purchased against the emissions and to drive climate change mitigation measures through worthy projects. KingSett chose to invest in Gold Standard carbon offsets, widely regarded as among the highest-quality carbon offsets in the world. Gold Standard offsets fund emissions reduction projects and sustainable development around the world. As one of the most prestigious addresses in Toronto’s financial district, KingSett is proud to add ZCB Standard certification to 40 King St. W.’s accolades. While KingSett’s efforts in obtaining the certification tie closely to its own environmental, social, and governance goals, the organization hopes to inspire other owners and corporations to consider a zero carbon path.
