NEWS VANCOUVER ZERO EMISSIONS BUILDING CENTRE OF EXCELLENCE TO LAUNCH THIS SUMMER The Vancouver Regional Construction Association [VRCA], in partnership with the City of Vancouver, Passive House Canada and the Open Green Building Society, has announced that the Vancouver Zero Emissions Building Centre of Excellence [ZEBCoE] will open this summer.

The mission of the Centre is to rapidly accelerate the capacity of local developers, designers and builders to deliver cost-effective, attractive, zero emissions new residential and commercial buildings in Vancouver. The Centre aspires to learn from both local and global leaders and to expand its mission to support zero emissions building across the province.

“The development and launch of ZEBCoE aligns perfectly with our association’s strategic direction to foster an environment that encourages collaboration, innovation and continuous learning across the industry,” says VRCA President Fiona Famulak. An official launch of the Centre is planned for summer 2018. ffamulak@vrca.ca

LAFARGE TO USE RESIDUALS FROM WATER TREATMENT TO MAKE CEMENT Lafarge Canada Inc. and Metro Vancouver have reached a three-year agreement to use water treatment residuals from the Seymour Capilano Filtration Plant as material in cement manufacturing, and thus become part of the circular economy. The residuals are the solids removed during the drinking water filtration process, and and treatment chemicals [coagulants and polymers]. They contain a chemical profile that mimics that of red shale, a virgin aggregate input required as a raw material in cement manufacturing.

The agreement means that fewer virgin materials would be needed to be mined, while residuals would be kept out of the landfill. jennifer.lewis@lafargeholcim.com

RESILIENT DESIGN RESILIENCE IS THE NEW SUSTAINABILITY

After the catastrophic flooding in Moncton, Fredericton, Winnipeg, Ottawa, Calgary and the devastating wildfires in fort McMurray, Alberta, Canadians are realizing that climate change is one of the biggest challenges that the world faces. Tackling climate change is a top priority for all levels of government - at home and internationally.

RESILIENCY

Climate change has already had far-reaching impacts on infrastructure and has profound effect on sustained operation of the built environment. This trend is likely to accelerate in the coming decades. The main threats to infrastructure assets include damage or destruction caused by extreme weather events. Besides efforts to reduce climate change, decision makers need to prepare our infrastructure for the climate change that cannot be avoided.

Building code requirements have an emphasis on life safety, i.e. allow major damage or total collapse providing the occupants can be evacuated prior to or during the event. Excessively damaged buildings have a slow recovery and may even prevent recovery for some neighbourhoods.

But What Exactly is Resiliency?

Resiliency can be defined as the adaptability of a system (communities) to maintain its function and structure in the face of turbulent internal and external change.

The key attributes of enhanced structural resiliency are improvements in: • • • • • • •

Longevity (service life) Robustness Sustainability Life safety Durability Adaptability for reuse Resistance to disasters

Thoughtfully chosen, properly designed new construction can significantly improve both the resilience to natural and man-induced disasters and the long-term sustainability of modern urban environments in the 21st century. In particular precast concrete construction has the ability to provide extremely durable buildings at similar costs to traditional construction while also providing a more sustainable construction form, in terms of higher energy efficiency, lower embodied energy, safety, and a quicker recovery after a disaster.

CPCI, NPCA, PCI and Members are the leading source of technical resources (Body of Knowledge (BOK)) for the precast concrete industry in North America. From this BOK, building codes, design guides, educational programs, certification, sustainability programs, and new research ideas are derived. This joint industry initiative develops, maintains, and disseminates the BOK necessary for designing, fabricating, and constructing sustainable and resilient precast concrete structures.

Champagne Quarry Park in Calgary is an example of what is happening in many parts of the country where former industrial lands along waterways and near city cores are being rejuvenated as self-contained communities.

The project comprises five individual - four- and five-storey total precast buildings located on top of two levels of interconnected underground parking.

The architecture is French provincial, which is supported with details such as natural stone and steep-pitched roof lines. It has balconies and large windows and arched detailing over the top windows. Colour palettes, construction materials and specifications differentiate this property from any other in Alberta.

Precast Concrete is Safe Everybody knows that precast concrete does not burn! Not only is the structural stability maintained for longer periods, but precast concrete construction prevents the spread of fire from one building to another.

St. Teresa Place facility, located in Calgary, Alberta, is a total precast concrete supportive living building. Located at 10 Redstone Place in Northeastern Calgary, this supportive living complex is four storeys in height, contains 250 units and has a gross building area of 19,000 square metres (205,000 square feet). The building was completed on a condensed installation schedule, without compromising the architectural design.

This building method facilitated a fabrication and installation schedule of mere months – starting with precast production in June, precast installation starting in August and completion by the end of November. Total precast construction provides a state-of- the-art solution for continuing care needs by delivering a safe, fast, sustainable and resilient building.

Precast Concrete is Tornado, Hurricane, and Wind Resistant Precast concrete is resistant to tornadoes, hurricanes, and wind. Debris driven by high winds presents the greatest hazard to occupants of homes, offices and commercial facilities during hurricanes and tornados.

Point Towers, Phase 5 at The Barrel Yards in Waterloo consists of two 25-storey, 85-metre [279 feet] towers of 357 living units sitting on a two-storey podium with one level of underground parking. Total ground floor area is 41,877 square metres [450,290 square feet].

The Point Tower was originally designed as a cast-in- place concrete structure with precast concrete and window wall cladding, but during the design phase the client requested to change to a total precast building to shorten the construction schedule and reduce financing costs. In comparison to a similar building also under construction on the same property, but cast-in-place, the Barrel Yards precast concrete project started six months later and finished four months earlier, which greatly reduced construction and financing costs.

Precast Concrete is Earthquake Resistant Precast concrete structures are designed to the seismic requirements of the National Building Code of Canada.

William’s Court - Groupe Lépine opted for precast concrete construction because of its fast construction, its durability, and for its lower cost made possible by the tightly controlled and relatively short production process.

Groupe Lépine selected a white hammered finish and the precaster also used a brick form liner mould that was used to simulate a brick wall, which was then stained at various locations. The illusion is quite dazzling. Even natural stone was used in several locations, with some precast panels having over three different finishes or colours.

Precast Concrete is Ecological Made of natural raw materials, locally available almost everywhere and in an enormous quantity, precast concrete minimizes the whole life cycle impact on the environment when compared with other construction materials.

UBC CAMPUS ENERGY CENTRE Vancouver, BC COMMERCIAL/INDUSTRIAL [SMALL] AWARD Jury comments: This is a beautiful solution for a building type that has traditionally been tucked away from public view. The elegant way in which the building reveals its inner workings makes it not only a striking piece of architecture, but an important didactic tool for the University of British Columbia.

In 2007, The University of British Columbia [UBC] committed to reduce its greenhouse gas emissions by 33% from its baseline, by 2015. The Campus Energy Centre [CEC], certified LEED NC 2009 Gold, is an integral part of this reduction strategy. The CEC, a new high-efficiency hot water heating plant and district hot-water distribution loop, replaces UBC’s steam boiler plant constructed in 1925. It is a major contributor to UBC achieving its emission targets while simultaneously redefining public interaction with district energy infrastructure.

The CEC serves over 130 buildings, or 110,000 m2 of campus development delivered through 14 km of underground insulated pipe. The 1,900m2 building houses all process equipment including three 15 MW boilers with capacity for expansion to a total output of 80 MW.

The major sustainable design strategies were to locate the facility in a pre-existing parking lot; establish a comprehensive storm-water management plan that included pervious paving, retention, detention equipment and rain gardens; harness the massing of the facility to drive natural ventilation; utilize as much structural engineered wood as possible to offset embodied carbon; and to design the building as a “living lab” that showcases and communicates the building systems.

The CEC, with its elegant zinc cladding and expansive window openings, greatly enhances the experience of the public realm. The main street running along side the CEC now includes a generous sidewalk with planted rain gardens that treat the project’s storm water runoff, and striking views through the glazing of the 17-metre-tall exposed cross laminated timber [CLT] boiler bays.

The use of exposed CLT and glulam engineered wood on the interior creates a warm, welcoming atmosphere while still achieving structural and practical requirements. A Life Cycle Analysis [LCA] was carried out using the ATHENA methodology to compare a steel and concrete reference building and the proposed glulam and CLT building. The LCA indicated an 18% global warming potential reduction by using engineered wood.

AWARD

Jury comments: We were impressed by the waste reduction that resulted from factory prefabrication, the speed of construction, the technical innovation, the holistic approach to sustainability – including carbon sequestration and life cycle issues. This is a building many people can learn from.

Completed in 2017, Brock Commons Tallwood House is an 18-storey, 404-bed student residence located at the University of British Columbia. With a height of 53 metres, Brock Commons is the world’s tallest mass timber tower. The LEED v4 Gold target project aspires to be a model for a future that features extraordinarily ordinary mass wood buildings that are quick, clean and cost effective to construct and that maximize carbon sequestration and the reduction of greenhouse gas emissions.

The innovative project demonstrates that a mass wood building can be comparable in cost to a traditional concrete building. To be truly environmentally meaningful, mass wood structures must be incorporated into buildings of all types and sizes, from the audacious to the everyday, whether the wood structure is exposed or not.

Using a “keep it simple” design approach, the innovative mass timber structural system proved to be economically viable, repeatable, and adaptable to other building types and uses. The project was delivered on time and on budget, demonstrating that encapsulated mass timber buildings can be constructed quickly and economically, while delivering significant environmental benefits.

The wood used at Tallwood House was sourced from sustainably managed forests in British Columbia, where less than one third of one per cent of public forests are harvested annually, with a legal requirement to regenerate all harvested areas. Mass wood construction helps reduce greenhouse gas emissions created by the built environment since wood stores carbon and is less carbon intensive to produce than other building materials. With its 2,233m3 of wood, the building stores 1,753 metric tons of carbon dioxide.

an exceptionally low embodied carbon intensity of 236 kg CO2-eq/m2 Global Warming Potential [GWP]. Compared to a similar, conventional concrete structure, Brock Commons achieved 43% savings on global warming potential, 60% on Ozone Depletion Potential, 47% on Eutrophication Potential and 35% on all other environmental indicators.

The mass wood structure and facade were erected by a crew of nine workers in 66 days. There are 29 CLT panels per floor for a total of 464, with 78 glulam columns per floor for a total of 1,302.

The use of prefabricated timber and steel construction components ensures flexibility of use and adaptability to other functions over the life of the building, after which demountability, repurposing, and recyclability of the components will be possible.

The building has received considerable national and international attention, with over 1,300 people from around the world visiting the project during construction. Interest from government officials, design and construction professionals, forestry industry representatives, academics and students suggest that the impact of the project will be both profound and far-reaching.

HARVEY WOODS LOFTS Woodstock, ON

The project converted the vacant Harvey Woods Knitting Mill, a 1918 three-storey solid brick factory in downtown Woodstock ON, into 54 one-bedroom affordable

apartments.

The

existing

industrial structure and tight construction budget of $120,000/unit placed significant constraints on the design, which were resolved by creating long and narrow unit types. As a result, the centre of the building was carved out to create a three-storey covered atrium to bring natural daylight into the residential corridors.

SABMag - SUMMER 2018

EXISTING BUILDING UPGRADE AWARD Jury comments: The retention and rehabilitation of existing buildings, particularly in the centre of small cities such as this, addresses sustainability issues of embodied energy as well as social and cultural continuity. We were impressed by how an atrium was created within the existing building as a community space, and by the improvements in energy performance – particularly in the context of a large social housing project.

Building section Many of the original building features remain visible, including hardwood maple floors, wood columns, and steel beams. The historic brick facades were kept as-is, opting for interior insulation and large, high-performance INLINE Fiberglass windows that complete the daylighting strategy. Archival photos of women working in the factory were incorporated into the new curtain wall entrance, tying the renovation to the building’s storied past.

The building’s energy efficiency strategy is completed with the addition of a geothermal well system and water-to-water heat pump for heating and cooling. Overall, the building’s energy intensity of 76 kWh/m2/year is a significant achievement in the conversion of this historic factory. The most important achievement, though, is creating 54 affordable apartments for the most vulnerable in this rural community.

Given the pre-existing conditions of the building and its placement on the site, the key strategic decisions revolved around how to improve the access, circulation, and daylighting of the building. Working to preserve as much as possible of the original structure and to create the maximum number of units within the limited budget, the design team arrived at a perimeter layout, organized around a central atrium. Five different unit layouts [some deeper and narrower, some shorter and wider, accessible units] are grouped together to optimize circulation and maximize access to daylight and views.

Where others saw a decaying property vacant for over 20 years, the non-profit developer saw the derelict factory as an opportunity: it was a well-known landmark in the downtown core, with transportation and other amenities nearby, and well suited to fulfill the affordable housing need for low-income residents.

The historic chimney

[only one of three left in the Woodstock area] was fully restored as a demonstration of community resilience.

The project opted for an envelope-first approach towards energy conservation, retrofitting the existing masonry walls with interior spray foam insulation, and large, highperformance INLINE Fiberglass operable windows.

These are fitted with double-pane argon-filled Insulated Glass Units [U- value of glass 0.25] and a Solar Heat Gain Coefficient of 0.34 for the south and west elevations, in order to reduce unwanted solar gains during the cooling season. The closed loop geothermal system [three intake wells + three recharge wells] and water-to-water heat pump cover 100% of the heating and cooling load for the building, excluding ventilation.

Thanks to the adaptive reuse strategies, both the historic value and embodied energy of the Harvey Woods Lofts will be conserved, and the building will continue to serve its community for another 50 years or more.

ENVIRONMENTAL SCIENCE AND CHEMISTRY BUILDING Scarborough, ON INSTITUTIONAL

[LARGE]

AWARD

Jury comments: This building has a particularly innovative approach to solar shading, creating a dynamic faรงade and animating interior spaces. This approach carries through to the other environmental systems which are exposed to view, not simply to celebrate the technology, but to monitor performance, facilitate research and identify potential improvements.

As befits a new building for the study of environmental sciences and chemistry, this facility, located on the Scarborough campus of the University of Toronto, is strongly rooted in sustainable design solutions. The facility features collaborative learning opportunities while providing flexible lab space that ensures adaptability for the ever-changing nature of research and teaching methods.

The 10,000m2 building connects laboratories and academic offices around a sky-lit atrium designed to encourage collaboration and exchange. Thematically, the Environmental Sciences and Chemistry Building is inspired by nature to reflect not only the academic pursuits of these disciplines but also its setting on the edge of a wooded ravine.

The building incorporates many unique and progressive systems that combine to achieve a significant reduction in energy consumption in a process-energy-driven facility. These include geo-thermal boreholes beneath the building and earth tubes. These systems are complemented by a high-performance building envelope including innovative solar shading. The project also features storm water capture and recycling, and a solar renewable-ready Tremco green roof.

During design and construction, material selection and performance was approached as a collaborative effort to balance functionality and performance with sustainability.

The design of the building envelope involved the architectural team, energy modeller, building science professional, material and system manufacturers and suppliers, as well as construction personnel in order to achieve the durability, thermal, and aesthetic performance targets for the project. This collaborative process resulted in a cladding system and innovative vertical solar shades that minimize thermal bridging through the vertical shading fins, allow for maintenance and replacement both for the fins and curtainwall, and ensure air and water tightness throughout.

The five-storey building connects laboratories and academic offices around a sky-lit forum and crossroads designed to encourage collaboration by providing gathering spaces in wide corridors, meeting rooms and white boards throughout. The building also embodies new thinking in laboratory design – open, transparent, flexible and adaptable, while providing a safe and secure work environment for students and researchers.

As an active research and teaching laboratory, with nearly 120 fume hoods distributed in various labs throughout the laboratory wing, ventilation and make-up air posed a significant challenge to the design team. To improve energy efficiency, a series of earth tubes were designed to help temper incoming fresh air drawn from the adjacent courtyard before introducing it into the building.

OKANAGAN COLLEGE CHILD CARE CENTRE Penticton, BC

INSTITUTIONAL

[SMALL] AWARD Jury comments: As a structure designed to the rigorous Passive House standard, this building is notable for the beauty and simplicity of its environmental systems.

The building relies mostly on local materials and very economical passive design strategies, yet also addresses cross-cultural issues and creates a symbolic new gateway to the college campus.

The Okanagan College campus straddles the boundary between the City of Penticton and the Penticton Indian Reserve. The college and the En’owkin Centre, the cultural centre of the Syilx nation, are located directly across the river from one another. To acknowledge the cross-cultural nature of the community it serves, the Child Care Centre has bilingual signage, and each of the four Child Care spaces has been given the name and colour palette of one of the four traditional food staples [or ‘chiefs’] of the Okanagan people.

A desire to connect indoor and outdoor spaces was at the core of the design model for the Child Care Centre. Each of the four Child Care rooms has a contained outdoor space equal to twice the area of the indoor space. The design of the rooms focuses on large windows and doors which provide constant visual and physical connection to the outdoor rooms.

ECOLOGY ACTION CENTRE HEADQUARTERS Halifax, NS COMMERCIAL/INDUSTRIAL

In April 2016 the Ecology Action Centre [EAC] employees, 4,500 members, countless volunteers, and the public at large. Designed and constructed through a three-year community engagement process, this 480m2 building is a showcase for environmentally-sensitive renovation and densification in a tight urban setting.

Located in Halifax’s North End, the project embodies the EAC’s values and goals, including exemplary energy performance and the creative use of salvaged and natural materials. Most importantly it is a welcoming and inspiring space for community and staff to connect, learn, and work together.

The project demonstrates a commitment to increasing public and industry buy-in for sustainable redevelopment. Through the educational efforts of the owners and extensive community involvement, the project shows what can be achieved, even on a tight budget. The result is a fully renovated three-storey, century-old building that uses 50% less energy than the original two-storey structure, even though the floor area was increased by 50%.

The EAC wanted to reinforce its connection with the community and, by lowering the western half of the main floor to sidewalk level, created a new accessible, 4-metre high community gallery and meeting space. Large windows reveal the activities within, and give the EAC an inviting street presence.

From start to finish, the project was a true community effort. In addition to the hours dedicated to community consultation, there were over 1,400 hours of volunteer labour on the construction site – providing those involved with invaluable hands-on experience of sustainable building practice.

Responsible urban densification was a key focus of the project. Building up increased the floor area without increasing the footprint or impacting existing green space. The renovation took advantage of the building’s orientation and elongated form to maximize daylight, views and natural ventilation strategies. Interior finishes are clay or milk paints and earth clay plasters. These finishes are VOC-free and help regulate occupant comfort through humidity control.

The building was wrapped in a new airtight weather barrier and an exterior insulation package that improved the walls to R-32. A minimum of 600mm of cellulose insulation was added to the roof [R-75]. Insulated steel door cut-outs were diverted from the waste stream and the polyurethane foam component was used as sub-slab insulation [R- 16].

The project team salvaged an interesting array of materials including floorboards from the existing building which became a feature wall in the community gallery, beautiful oak doors from a recently demolished building, and high-density fibre cement panel off-cuts from another project.

Existing walls, floors and roof saved 40 tonnes of wood, 3 tonnes of metal, 20 tonnes of "mixed waste", and 7 tonnes of drywall/plaster that might otherwise have gone to the landfill. The foundation reuse saved approximately, 90 tonnes of concrete. Together, this amounts to 527,208 MJ of embodied energy saved, equivalent to 9-1/2 years of operating energy.

The Centre de Découverte is located in the Parc National des Îles-de-Boucherville, a group of five islands in the St. Lawrence River, a few kilometres from Montreal. The building is both the main visitor centre for the park and a showcase for the SÉPAQ [National Parks of Quebec] network. Built entirely in wood, the Discovery Centre exemplifies an integrated approach to architecture that combines high performance, bright and inspiring interior spaces, and a respect for context.

and professionals from a wide spectrum of design disciplines.

The building embodies the principles of bioclimatic design, with each gesture contributing to the aesthetics of the pavilion as well as to the overall sustainability of the project. Modelling of ventilation, daylight and energy systems was used to optimize building design and performance.

The location and form of the building were selected based on sun path analysis, wind patterns and a variety of ecological criteria.

Environmental impact studies were carried out to ensure that the integrity of local ecosystems was preserved or enhanced. This included lighting design to minimize the impact on nocturnal and migratory animal and bird species, the collection and redistribution of rainwater to maintain hydrological cycles and plant health, and the careful shaping of the curvilinear building plan to preserve trees.

This ecological agenda carries through to the specification of materials and finishes. The structure uses FSC [Forest Stewardship Council] certified wood; the cladding is locally-sourced eastern cedar and interior finishes have low or no VOC emissions.

In addition to the sequestration of carbon, wood is low in embodied energy: construction of a wood stud wall results in 1.6x less greenhouse gas emissions than a steel wall, and 4.0x less than a concrete wall – contributing to superior life cycle performance.

The interior of the Discovery Centre is bathed in natural light thanks to large expanses of triple-glazed curtain wall facing the park. Low level vents admit fresh air that drives the natural displacement ventilation system, exhausting stale air through vents at the top of the central light well. Wood louvres and overhangs protect the glazing from unwanted solar heat gain.

The combination of a high-performance building envelope, careful implementation of bioclimatic design principles and efficient mechanical and electrical systems result in a building that uses 40% less energy than the reference building, with 100% of this energy supplied from hydroelectricity – a renewable source with a low environmental impact.

COMMERCIAL/INDUSTRIAL AWARD

Toronto, ON [LARGE]

Jury comments: We were impressed that this tower incorporated so many innovative sustainable features, whether or not they would achieve credits on a check list. Things like individualized climate controls for office workers, and a public park rather than simply amenity space for building occupants, were notable examples of this approach.

The office building at One York Street is part of a 200,000m2 mixed-use development along the Central Waterfront in the new South Core of Toronto. One York is Toronto’s highest-scoring LEED Core+Shell certified office project to date – achieving Platinum certification at 89 points. Situated between Union Station and Lake Ontario, it occupies two-thirds of an entire city block at the foot of York Street between Lakeshore Boulevard and Harbour Street. The 35-storey office tower is one of three towers [two are residential] rising from a three-storey retail podium. The fourth floor of the podium provides public roof garden access, a shared food court and a significant health/fitness centre. Together, all connected components create a unique metropolis-like complex inspired by the Waldorf Astoria in NYC. Alan Murphy, project lead with sustainability consultant Green Reason writes: “With so much of the design focused on energy and water efficiency, it is critical to ensure that the building operates as designed and that occupants understand the design and remain engaged in ensuring that the operation balances with their needs.

As both owner and building manager,

Menkes understands the importance of continuous tracking, optimization and engagement with their own team and their tenants.

Tenant engagement helps property managers build a better relationship with tenants in order to create positive behaviour change in the building environment. At One York a Green Team has been created, comprised of property management and tenant representatives. Having a Green Team is one of the most effective ways of delivering a tenant engagement program and provides a platform for effective communication and collaboration to accomplish One York’s sustainability goals. Green Reason’s role is facilitating Green Team meetings and related events.

We are also tracking energy and water consumption information for One York in order to review actual energy and water use against design predictions. This not only allows the team to identify and address any issues with system operation but also supports the reporting requirement under the Province of Ontario’s Energy and Water

is key to achieving the City’s greenhouse gas emissions reduction target of 80 per cent by 2050.”

Beyond quantitative building performance, One York also focuses on human wellbeing. This meant maximizing access to fresh air, natural light, allowing personal control

of one’s microclimate, and encouraging active transportation modes, all the while minimizing capital and operational costs, adverse environmental impacts and unnecessary resource consumption. One York is an elegant demonstration of how this can be done successfully.
