By participating in the Enbridge Savings by Design Workshop, we were able to discuss real costs of choices, both for construction and long-term operating. The overall building massing and layout was set by very complex program and siting restrictions, so the areas in which we benefited greatly were in rethinking storm water management on site, window type and performance, exterior wall assembly, and healthy materials. The mechanical engineering part was also indispensable and so instructive; highlighting important and easy changes, discussing more complex upgrades, and understanding the long-term and performance impacts of our systems, both as climate change worsens and as building systems need replacement and upgrades. The Enbridge charrette provided the perfect opportunity to make clear and informed choices that brought our project to the next level of energy, health and operating performance. It saved construction and operating costs and made for a healthier building. — Chantal Cornu, LGA Architectural Partners
In 2018, Evergreen Brick Works was in the midst of an ambitious effort to transform the historic Kiln Building – and make it carbon neutral by using the right energy at the right time. Early in the process, Enbridge led a Savings by Design workshop for the project. On a fast track project, this provided a tremendous opportunity for the integrated design team to reflect on the early trajectory set in the project, and obtain informed perspectives from invited experts on enhancing it. The workshop also provided a spring board to brainstorm how the Kiln Building project could serve as a catalyst to transform the entire Brick Works campus to be carbon neutral, which has been a longstanding vision of Evergreen. The Savings by Design workshop struck a great balance between both blue sky and detail level thinking. It was informative, fruitful, and an overall positive experience. We’d highly recommend Enbridge’s Savings by Design workshop program for anyone thinking about making more sustainable buildings. — Drew Adams, Associate, LGA Architectural Partners

New study discovers important gaps in life-cycle approach used to account for GHGs in buildings By Philip Gass, Senior Policy Advisor, International Institute for Sustainable Development
In Canada, there is rising interest in how building materials may affect greenhouse gas emissions (GHGs), and whether innovations and choices in these materials can help the country meet its emission reduction targets. The fact that over 30 per cent of GHGs come from the communities and structures we build for ourselves underscores the need for us to get this right. To date, evidence for optimizing the choice of building materials has largely been drawn from life-cycle assessment (LCA) studies that consider
the GHG (and other) impacts of building products at each phase of their “cradle-to-grave” lifespan (i.e., production, use and end of life). While LCA is the best-available approach for evaluating GHG performance of alternative building products and designs, policy-makers and building designers should be aware there are also limitations, challenges and uncertainties that need to be considered when looking to decarbonize our buildings. We should exercise caution when making decisions that advocate for one building material over another. Recent research by the International Institute for Sustainable Development (IISD) has identified serious gaps in how emissions from building materials and products are being measured and accounted for. Failure to account for all carbon emissions may undercut today’s climate change efforts and shortchange future emission reduction opportunities.
International Institute for Sustainable Development • IISD.org SABMag - SUMMER 2019

Our study, Emission Omissions: Carbon accounting gaps in the built environment, found while LCAs are the right tool to measure carbon emissions, more data, transparency and robust LCA standards are needed, especially with respect to accounting for biogenic carbon from wood products.
Flawed assumptions could misdirect efforts to reduce GHGs LCAs can be an effective approach for identifying ways to reduce carbon emissions in the building sector. But without proper care, they can produce results that are misleading or incomplete, potentially leading to more GHG emissions than anticipated. Existing LCAs produce widely variable results, even for similar buildings, for two main reasons: first, there remain important gaps in the data available; and second, assumptions and uncertainties that may have significant impact on LCA results are typically not disclosed. This can lead to flawed conclusions, misdirected efforts and suboptimal GHG outcomes for Canadians.
LCAs ignore significant sources of GHG emissions from wood products Our study found current LCA models typically do not track the carbon emissions or sequestration of “biogenic carbon” from the extraction and

end-of-life stages of wood building products. Biogenic carbon refers to carbon emissions from disturbances of living organic matter, such as carbon losses from soil disturbance, from the conversion of old-growth primary forest to less productive secondary forest, as well as losses from imperfect post-harvest reforestation efforts. Collectively, these emissions can represent up to 72 per cent of a wood product’s total life-cycle emissions, challenging the prevailing assumption that wood construction materials are less carbon intensive than other construction materials, such as concrete and steel.
Important regional factors are often overlooked LCAs also tend to discount significant regional variability in the GHG emissions of different materials. These factors include the regional variations associated with the extraction of raw materials, the carbon emission intensity of the production phase and the disposal conditions at the end-of-life stage. For example, while production intensities can vary significantly from site to site, LCAs typically use average national, continent or global data.
Existing LCA models may misrepresent embodied emissions LCAs comparing building materials can exaggerate the importance of one life-cycle phase (e.g. the embodied emissions of materials) by ignoring or discounting the contribution of other significant life-cycle emissions, such as operational stage emissions and the GHG impacts of other building systems. Used in isolation, these results can lead to decisions that are too narrow in scope and shift focus away from a more comprehensive picture of GHG emission reduction opportunities in buildings.
Building efficiency matters a great deal Despite tremendous progress on building efficiency, operational energy consumption remains the most important source of GHG emissions from a building over its life. Therefore, material choices need to be made on a building-by-building basis, driven not only by the need to reduce embodied GHG emissions, but by a holistic understanding of the role materials can play in enhancing the structure’s “whole life” environmental performance.
When combined factors such as forest regeneration rates, soil carbon loss and primary-to-new-growth-forest-conversion are all accounted for, the cradle-to-grave embodied emissions for a wood building could be 6% greater than for a concrete building.
When adding use phase emissions to the embodied emissions, the carbon impact of a wood building could be 1% greater than for a concrete building

The way forward: a recipe for a smaller carbon footprint In order to ensure our building sector helps meet Canada’s Paris Agreement goals, there are three recommendations that should be strongly considered by policy-makers and builders. First, improvements in energy efficiency, durability and developing new low- or net-zero-energy buildings offer the highest GHG mitigation potential from the built environment sector. Policy-makers should focus on promoting building resilience and longevity paired with deep efficiency improvements, to achieve the most significant GHG emission reductions. Second, LCA remains the right approach, but more data, transparency and robust standards are needed. Policy-makers and building professionals looking to decarbonize buildings should exercise caution when making decisions that prefer one building material over another. Uncertainties, assumptions and omissions in LCA studies, particularly with respect to the biogenic carbon emission, suggest comparisons across building materials are fraught with complexity, and should be approached carefully. Third, the way to achieve deepest embodied GHG emissions improvements in buildings is to focus equally on material efficiency and incenting decarbonization across all material manufacturing sectors. In fact, most buildings use some degree of all three primary building materials (concrete, steel and wood). It makes sense to focus on policies, strategies and technologies that can incent GHG reductions in each building material sector, as part of a comprehensive building decarbonization strategy. Deep emission reductions, on the order of 60 to 80 per cent, are required to meet Canada’s longrange emission reduction targets. For the building sector, this will require large-scale investment in new low-carbon technologies and practices.
International Institute for Sustainable Development • IISD.org 10
SABMag - SUMMER 2019
In the wake of the Canadian government’s report noting rapid temperature rise across our country, the imperative to look more deeply at building materials as sources of – and solutions to – climate change is clear. Greater transparency and robust standards are needed for our main building carbon accounting approach if we are to get decarbonization right. For more information: www.iisd.org/library/emission-omissions
IISD study methodology This study consisted of a review of existing LCA guidelines, methodologies and literature; an analysis of major documented uncertainties and major variabilities that can be expected in the Canadian context; and an analysis of the potential impacts of changes in technology and the built environment and how they fit with longer-term climate objectives. The IISD research team worked under the guidance of an advisory group comprised of university- affiliated academics, notable environmental organizations and architects/designers from the green building community, including the Natural Resources Defense Council, Environmental Defence, CPAWS, Queen’s University, the University of Toronto, the Athena Sustainable Materials Institute, the International Reference Centre of the Life Cycle of Products, Local Practice Architecture + Design, BuildGreen Solutions and Boreal Songbird Initiative. The study was funded by the Cement Association of Canada.

provides daylight, views and natural ventilation through highand low-level operable windows. The typical classroom and office module is 7m deep, bringing 75% of program space in proximity of an operable window. These strategies help achieve the Living Building Challenge standards for the ‘Civilized Environment’, ‘Healthy Interior’ and ‘Biophilic Environment’ imperatives. Occupancy sensors and daylighting controls along with 100% LED lighting contributed to a 48% reduction in overall lighting power density compared to the ASHRAE 90.1-2007 baseline. The problem of meeting the energy-intense technical requirements of the trades shops and labs while at the same time achieving the sustainability targets was solved by first examining in detail how the program spaces would be used, then inputting the information into a series of energy models, and finally analyzing the data to determine how to achieve the most optimal results. The fact that a trades facility with its high energy-use requirements for power tools and equipment can achieve this level of energy self-sufficiency sends an important message that a sustainable future is no longer a distant prospect, but is attainable now. 4.

Jury comments: We hope this project marks the beginning of a new era in which the invisible infrastructure that has longsupported urban life is brought out into the daylight. Only through making infrastructure visible can we fully grasp and understand the implications of our linear systems of production, consumption, treatment and disposal. Alongside the learning opportunities provided by this facility, the volume of waste discharged into the ocean has been reduced by 90% compared to its predecessor and the bio-nutrient by-products can be used for industry and agriculture.

The centre has two main components – the office and the greenhouse space. The transparent greenhouse space reflects the rooflines and volumes of the residential streetscapes while showcasing this paradigm shifting technology. Staff offices and support spaces are located on the upper floor along the north and east perimeter, with operable windows maximizing daylight, natural ventilation and views. At the former wastewater management facility, staff members were responsible for cleaning the malodourous open-air separation tanks. These same people are now responsible for tending the many plants flourishing in the greenhouse. They are connected to rather than segregated from their community

through the building location and its openness to the public. The project is LEED Gold certified, which is quite an achievement for a building of this size and type. The project team was able to double the facility’s treatment capacity while decreasing its energy use by almost half. Rooftop solar panels supply 10% of the building’s needs and a heat exchanger harvests the latent heat from the process sewage, eliminating the need for electrical or natural gas heating. By boldly reconsidering both an outdated, codified approach to utilities as well as the notion of what constitutes waste, the centre provides solutions to multiple complex problems: waste disposal, water shortages, energy efficiency, and pollution of the ocean by effluent. Many other great changes and challenges facing our society will require similar paradigm-shifting problem-solving for which this project provides a 21st-century precedent.

Evolv1 Waterloo, ON Evolv1 is a commercial office building targeting net positive energy and net zero carbon. In order to achieve this standard, the building must produce 105% of its own energy requirements. The 10,000m2, Class AAA building is located in the David Johnston Research + Technology Park, within Waterloo’s Idea Quarter.’ The goal of the project was to inspire development of regenerative buildings by producing an economically-viable prototype that works within the real market. The building is targeting LEED platinum certification and has been certified by the Canada Green Building Council as the first Zero Carbon Building in Canada. A multipronged low energy design approach was used to meet the client’s environmental goals, including a ground source open loop geo-exchange system, that significantly reduces the heating and cooling loads, and photovoltaic panels installed by VCT Group to produce more energy than the building was going to consume.

The design approach began with passive strategies to reduce the energy consumption before applying active strategies. The main passive strategies Included: orienting the building east to west to best control solar heat gain, with the ground mounted solar carports constructed to the south, thereby maximizing sun exposure; and an efficient building envelope with careful detailing to avoid thermal bridging; so, achieving an EDI of 24kWh/m2. The majority of the heating loads are met by the open loop geoexchange system, the first open loop system in Ontario, tapping into an existing aquifer below the site. The advantages of the open loop were lower cost, as only three wells were required, rather than a large field; and greater efficiency when compared to a closed loop system. Active strategies include a Variable Refrigerant Flow (VRF) HVAC system which heats and cools zones dependent on the localized temperature. The VRF HVAC also gains efficiencies by moving excess heat into cool zones before actively producing heat. Also, heat recovery ventilation system with 80% efficiency. Lastly, a solar PV array, comprised of ground-mounted solar carports and a standard rooftop ballasted system, is designed to produce 105% of the buildings anticipated total energy consumption, displacing 110 tons of CO2 annually – with no fossil fuels being used. With its sustainable strategies on display, Evolv1 tells a visual story of how sustainability can be achieved and invites the public and the development community to investigate its features. Not only does Evolv1 set the standard for sustainable, carbon-neutral and carbon-positive building design, it also confirms that this can be achieved whilst maintaining commercial viability.

The restored winter garden atrium serves as a collaborative workspace. Teknion supplied the demountable wall systems used in the project.
The openness achieved by removing generations of interior partitions provides greater flexibility for the building systems to adapt to future uses. The core of the Centre Building was also rebuilt. Systems were upgraded to the latest technologies through discrete means to ensure that the exposed structure of the towers remained as the original architect, Arthur Erickson, had intended. To this end, minimizing ductwork was important; a new “dynamic buffer zone” (a double skin created by adding an interior glazed wall around the perimeter of the building) and radiant cooling system addressed principal heating and cooling needs, allowing ducts to be sized for ventilation only. The extensive power and data cabling needs of a modern office are served through a low-profile access floor that allowed for maximum flexibility. To upgrade the workplace, a modular office design was developed that works with the coffered concrete ceiling grid, with office partitions and open workstations constructed using systems furniture to facilitate simple reconfiguration over time. The project is targeting LEED v4 Gold certification. This project was previously published in SABMag issue #63, Spring 2019.

Residential [Large] AWARD ACTON OSTRY ARCHITECTS INC. Jury comments: An innovative approach to high density urban living that takes advantage of Vancouver’s relatively mild climate to incorporate a courtyard typology to optimize the use of available site area. The project configuration promotes casual encounters and social interaction between residents and includes an accessible roof, with play space for children, raised planters for community gardening and a dog-walking area, providing a level of amenity that is rare if not unprecedented in a rental building.

exchange for provision of 100% rental housing. Located near a busy transit-oriented node in Vancouver’s Mount Pleasant neighbourhood, the 15,260 m2, 14-storey, mixed-use project includes 201 rental units, with a small ground floor retail component, all compactly contained in an open-air atrium court building typology that is new to Vancouver. In contrast to a traditional design approach that would typically feature a double-loaded corridor with units along both sides, the floor plan for The Duke instead features a single-loaded corridor with living units pushed to the outer edge of the site to create a central void space. Such a strategy substantially increases the number of units that can be accommodated on the site by maximizing the overall density within a prescribed 14-storey height limit. A traditional double-loaded corridor approach would have made the project economically unviable as a rental property; whereas the strategic decision to push the units to the site perimeter made the development viable for rental housing. The central void is transformed into a soaring, open-air circulation atrium over which a translucent Teflon canopy shields the space from the elements. The rental units are arranged around the perimeter of the trapezoidal-shaped site. This outdoor circulation space enables occupants to step out into a well-lit, weather protected environment designed to provide opportunities for residents to interact, even if only for a brief moment. An array of multicoloured front doors further animates the central atrium space.

Occupancy sensors, and daylight control are combined with LED fixtures for general lighting including refurbished heritage fixtures with increased light output, and colour rendering. Given the highly variable use and population of the conference facility, the mechanical system uses a demand control system that delivers fresh air as appropriate for comfort and use but throttles back when the rooms are empty and demand is reduced with commensurate energy savings. The building has been designed as a permanent facility with a minimum service life of 80 years. All systems and materials were selected with this in mind including terrazzo and stone floors, stone and wood walls and LED lighting.

This combination results in a structural system with a high potential for demountability, adaptability and reuse. Much of the material fabrication was carried out locally, including the panels which were prefabricated off-site in Golden, 60 kilometres north of Radium, and transported to the site in a choreographed sequence to maximize efficiency. The cladding was milled by a local mill and charred in Brisco, eight kilometres from the site. The building is organized and oriented to maximize passive strategies with a long linear form on the east-west axis, permitting natural daylighting and cross ventilation. Strategically located roof overhangs control solar exposure. Window locations are carefully calibrated to capture the views of the mountains and connect to the park while maintaining less than 40% window-to-wall ratio for energy efficiency.

Natural ventilation section 4 A high-performance building envelope, combined with passive design strategies and energy-efficient mechanical systems were used to minimize the building energy loads. A heat recovery ventilation system is augmented with large low-velocity fans and passive ventilation strategies to reduce cooling demand. Air source heat pumps and highefficiency boilers provide heating for the building, switching between systems to maximize efficiency. Beyond its energy-efficient design and locally-sourced materials, the building acts as the living room and social heart of the community. Co-locating the Library and the Hall provides cross-pollination and increases usage. The community kitchen was designed with the local seniors’ group to ensure accessibility and ease of use. The siting of the building creates a variety of exterior rooms within the public realm that can be occupied throughout the year. Indoor-outdoor connectivity promotes social wellbeing and expands year-round use of the adjacent park.

Uponor contributes to three winners Uponor is the leader in hydronic radiant system design and applications. Combined low-temperature heating and high-temperature cooling integrated with the use of alternative energy sources make radiant the ultimate in low-energy building solutions. Because water has 3,500 times more energytransport capacity than air, radiant is also fast becoming the energy-efficient alternative to forced-air systems. Radiant also helps building professionals acquire LEEDÂŽ for
Uponor contributed to three of the winning projects of the 2019 Canadian Green Building Awards: Building Blocks on Balmoral at Great-West Life by Prairie Architects Inc., Institutional (Small) Award, Wellington Building Rehabilitation by NORR Architects and Engineers, Existing Building Upgrade Award, and The Radium Hot Springs Community Hall and Library by Urban Arts Architecture, Institutional (Small) Award

Jury comments: This facility represents a significant milestone on the road to a circular economy, by converting millions of kilograms of domestic organic waste into valuable compost each year. By-products of this process are also re-engineered to create other marketable commodities, while solar panels, rainwater harvesting, grey water recycling and other environmental strategies have helped this project achieve a LEED v4 Gold rating – the first in Canada.

City of Calgary Composting Facility Calgary, AB Nearly 60% of single-family household garbage is compostable waste in Calgary. The City wanted to change this. First and largest of its kind in Canada, the Calgary Compost Facility (CCF) diverts 85 millionkilograms of material from landfills annually by converting it into a marketable product—compost. Opportunities to convert other resources that might otherwise have been overlooked also included: • 100% of the harvested rainwater is used for the composting process or to flush toilets and urinals • Greywater from the sinks and showers is diverted into the composting process • Solar energy is captured via an on-site photovolatic solar farm • Odour control is maintained using recovered wood chips • Sulfuric acid used to remove ammonia from the exhaust air in the composting process creates hazardous waste, ammonium sulfate. A process was developed to convert this to a neutralized crystallized form, which is used as fertilizer for agriculture.
1. Organic and compostable matter is received on the south side at tyhe numbered doors, the composting process occurs in vessels in the central area, and the north side contains the odour-eliminating components. The Administration and Education Building is to the left. 2. Petrochemical waste was removed from the site and replaced by native and droughttolerant plant species, and insect and bird boxes, to mimic the natural prairie landscape. 3. Staff meeting room. The administration areas are heated with Viessmann Vitodens 200-W condensing boilers. 4. The Administration and Education Building is the first LEED®v4 BD+C certified project in Canada. 5. The sorting area for compostable materials.

These innovative strategies were implemented despite a tight construction schedule. Ina visionary move, the CCF designed the adjacent Administration and Education Building to reach new sustainable heights. It is the first building certified under the LEEDÂŽ v4 Building Design + Construction rating system in Canada, achieving Gold certification. The Administration and Education Building boasts a high-performance envelope, reducing the amount of energy lost to the outdoors. It also takes advantage of energy-saving technologies such as condensing boilers, exhaust air heat recovery and high efficiency domestic water heaters.

PROJECT PERFORMANCE Energy intensity (building and process energy) = 65.3KWhr/m2/year Energy intensity reduction relative to reference building under ASHRAE 90.2 2010 = 39.1% Water consumption from municipal sources = 2,462 litres/occupant/year Reduction in water consumption relative to reference building under LEED = 50.4%
During the exothermic decomposition process, the process vessels heat up to very high temperatures, more than 60°C. To take advantage of this heat, ventilation air for the composting facility is fed over the process vessels, where radiant heat preheats the air prior to delivery within the building. In addition to controlling odour emissions, the fast-acting doors and air curtains also reduce the amount of heat loss to the outdoors. These energy-saving technologies allowed the City to claim the maximum number of energy-related LEED® points and credits. Low-flow plumbing fixtures were installed to limit water usage, and water for urinals and toilets is taken from the rainwater collection and reuse system. Reclaimed greywater from the building’s lavatories, showers, and harvested rain water, are also reused for the composting process in the adjacent composting facility. Remarkably, the facility is process water negative. Hazardous run-off from the composting process, leachate, is fully reused within the system. Leachate, greywater from the sinks and showers, as well as other sources of water throughout the entire process are all used to irrigate the compost material inside the process vessels. By maintaining a water negative process and reusing the leachate, the chance of a dangerous environmental release is exponentially reduced. Storm water on the entire site is reclaimed, stored in a storm pond, and then pumped in to be reused, offsetting the need for potable City water. The site water management system saves a substantial amount of potable water—a reduction of 40 million liters per year. The amount of potable water saved is equivalent to the amount of drinking water consumed by 40,500 people per year.
