According to the IPCC, meeting the 1.5oC target would require global net CO2 emissions to be reduced to 50 - 58% below 2010 levels by 2030, and to 94 - 107% below 2010 levels by 2050. To put these figures into context, Canada’s current carbon emissions are approximately 704 million tonnes per annum and our target for 2030 (if we are to play our part in holding the global temperature increase to 1.5oC) is 517 million tonnes.

This represents an annual decrease of 15 tonnes (or 2%) per annum, which may not seem too onerous, until you realize that this figure has averaged only 0.5% per annum since 2005. Compounding matters, the federal and (some) provincial governments continue to bicker over the Pan-Canadian Framework on Clean Growth and Climate Action, a suite of policies and protocols only projected to achieve a 1.4% annual reduction in carbon emissions at best.

To make meaningful progress, we must decouple action on climate change from politics. A shout-out to those local governments who have taken things into their own hands, with unanimous support from all parties. May many others join them in growing a pan-Canadian coalition of the willing.

viewpoint UNIVERSITY DISTRICT A Public Engagement Case Study University District, a new 80-hectare mixed-use neighbourhood in northwest Calgary, welcomed its first residents in 2018. The masterplan for the community was created by West Campus Development Trust (WCDT) through a public engagement process that set new standards of authenticity and transparency for projects of this type. The process helped WCDT to refine its plans, build trust with stakeholders and attract buyers.

Each Stakeholder Working Group opened with a review of the decisions made at the last meeting. WCDT set clear deadlines for feedback so that stakeholders understood their responsibilities. When it came time for the City’s public hearing on the land-use re-designation, there was little or no opposition - an unusual situation in a city where redevelopment has often been the source of time-consuming conflict between developers and citizens.

BEST PRACTICES In reviewing the engagement process, WCDT identifies several strategies that contributed to its success: • Target information: WCDT took maps of the surrounding communities, determined the relevant information for each group and distributed accordingly.

• Maintain focus: Each meeting had a clear agenda and a goal, and elements of the plan that could not be changed were not up for discussion.

• Hands-on: At meetings, provide plenty of practical elements: things to look at, interact with and draw or write on.

• Assemble expertise: Invite your design team, urban planner, traffic engineer, City staff, etc. – to make sure the decisionmakers have an opportunity to interact with the people who will live with the results.

• Define terms: Define terminology (especially development jargon like “multi-family dwelling”) to avoid confusion and assumptions.

• Don’t get flashy: Using simple, straightforward language and avoiding gimmicky technology is the best way to communicate clearly.

The conclusion for WCDT - it is not about who loses, but about how innovation can happen when we come together and think differently.

Streets’ policies are phased in.

• Green spaces: Parks and public spaces are a priority for both City and stakeholders, so WCDT tried to create conditions where its building partners could contribute to such spaces. As a result, University District will have 30% more trees than the average community.

BANK OF CANADA RENEWAL With a total floor area of approximately 79,000m2, the Bank of Canada complex occupies an entire city block in Ottawa’s central Parliamentary District. The complex consists of the Classical grey granite Centre Building, designed by Morani, Lawson and Morris and opened in 1938, flanked by two modern glass towers and indoor atrium designed by Arthur Erickson and completed in 1979.

By Jim Taggart

DESIGN INTENT The renewal project was designed to maintain the major architectural components of these historically significant structures, while bringing the facility up to 21st century standards for accessibility, fire and life safety, security and seismic performance.

In addition, the interior reconfiguration responds to the client’s desire to reinvigorate its operations by fostering a collaborative workplace culture. Moving away from private workspaces to an open environment, the Interior modifications consciously drive a future thinking workplace that will appeal to the brightest and best of the emerging young workforce.

These changes were strategic in nature, designed to meet the functional criteria in the most unobtrusive way possible.

For example, the careful demolition and replacement of the existing elevator and fire stair core in the office towers with new seismically upgraded versions eliminated the need for the more common, but more visually intrusive strategy of storey height steel cross-bracing installed behind the existing glass curtain wall. The perimeter of each tower floor thus became available for the creation of a 450mm deep ‘dynamic buffer zone’ to improve energy efficiency and environmental control.

With the installation of an interior wall of glass, this zone forms the plenum of a double envelope system that improves thermal performance and permits the pre-conditioning of air before it is distributed through the building. While a conventional suspended ceiling might have achieved the same effect, it would have concealed Erickson’s original exposed concrete structure.

Other new building systems include new rooflevel mechanical penthouses and main electrical rooms in the basement. Together, these systems result in overall operational energy savings of 70% over the existing condition, contributing multiple credits to the project’s LEED Gold designation.

INTERIOR RECONFIGURATION In the two towers, Erickson’s open-office concept column grid was restored. Open-plan spaces, modular furniture and sit-stand desks, create a variety of ‘me, we and us’ workspaces. The renewal seamlessly integrates power and data for 21st century digital technologies.

Resilience planning for communities to thrive in an unpredictable and changing world Across Canada, we are witnessing tremendous change, not only in our climate, but also in the urbanization of our cities. As our cities grow, we are experiencing greater pressures on our housing stock and community-wide infrastructure. In an often unpredictable and changing world, resilient design and planning is needed for our cities and communities to endure and thrive in both the short and long-term.

At Laurentian University’s Vale Living with Lakes research centre, the design team implemented a geothermal and air handling systemto accommodate a shift in seasonal energy use to less winter heating and more summer cooling.

There is both commonality and differences in the various Canadian cities in terms of their stressors and threats. With four out of five people in Canada living in cities, the resulting higher density and population in urban areas mean that cities are both agents for climate impacts and solutions.

Growing population through migration and immigration, the rising demand for transportation, and the growing need for infrastructure to provide safety, comfort, and security all combine to create different pressures on our cities.

The global nature of the world we live in also means that stressors and threats faced by other nations have either a direct or an indirect impact on our cities. While global in nature, these impacts need to be resolved at the local level through political will, technical expertise, and individual commitment and responsibility. The effort to find solutions to these issues or problems lie in a more collaborative and collective approach through leadership, community engagement, and collective action.

While climate change is one of the most important drivers for discussions regarding resilience, the conversations should not be limited to climate change; resilience needs to be looked through social, economic, and environmental lenses to identify risks—natural and manmade, acute and chronic—and respond through design and operations planning. Resilience needs to be addressed at multiple levels from a single building, to a district, city and regional level. Policies, strategies, and initiatives at each scale influence the resilience and performance at other scales.

resilience planning.

Beyond these efforts to define resilient design, influential stakeholders such as policy makers, lenders, and insurance brokers are adding their voice to the resilient design discussion and recognize that a collaborative and concerted effort is required to future-proof our communities. The Insurance Bureau of Canada realizes that “… there must a whole-society approach that includes investment in infrastructure and measures that will protect communities from storm surges, overland flooding, and other unforeseen events”.4 More recently, Bloomberg Philanthropies established the American Cities Climate Challenge, a $70M fund to support up to 25 US cities with technical assistance and backing in accelerating local climate programs.5 While most Canadian provinces are supportive of climate change policy and initiatives, we have yet to see initiatives emerge in the Canadian marketplace that offer the same level of technical and financial assistance.

While one solution may not fit all cities, provinces, or nations, there is a growing recognition that a multi-sectoral and proactive approach is needed to inform how we design robust communities.

Considering there are various issues and parameters that are interlinked, interdependent, and interrelated at these different scales, any effort to address resilience needs an understanding of these interrelationships.

Systems thinking enables an understanding of the relationships between the various interconnected and dependent systems, and helps identify the long-term costs and risks of a decision.

For

instance, climate change has an impact on both heat and precipitation patterns, which in turn has a direct impact on the availability of water resources.

While RELi offers a comprehensive approach to defining and measuring the resilient design attributes of a project, each project should begin with an investigation of the social, economic, and environmental risks and vulnerabilities facing it.

In an effort to

create projects that are proactively addressing issues of climate change, we at Perkins+Will, aim to answer these questions for every project: 1. What are the climate projections in the project area?

2. What are the vulnerabilities and cascading consequences

a holistic and systems-based approach to resilience was adopted that included social, economic, and environmental measures.

In addition to raising the site above the Flood Control Level, various green infrastructure strategies were adopted including roof gardens, rain gardens, and bioswales to address stormwater management. A large open space network of over 16 acres plays multiple roles in supporting both social and environmental resilience, including the integration of existing natural features that support habitat restoration, biodiversity, and biophilia. The integration of bicycle and pedestrian trails, parks, and outdoor recreation areas support active lifestyles and promote health and well-being.

Fraser Mills, the site for a former sawmill, was instrumental in the establishment of the surrounding neighbourhood of Mallairdville and supported the local economy during its operation.

Acknowledging this legacy, a production and innovation hub with light manufacturing and retail has been proposed.

By promoting local businesses and encouraging entrepreneurship, the long-term vitality and economic health of the community is supported. Recognizing that community cohesion is critical for resilience, a much needed public aquatic and community centre along with a destination waterfront public park are proposed to benefit the larger community.

Q LOFTS CONDOMINIUMS - Thoughtful sustainable design, creative energy efficiency, and the lowest condo fees in Halifax

Developer/builder POLYCORP is known for extraordinary energy efficiency. Its latest project, Q Lofts, raises the bar even further, illustrating the company’s mandate to treat energy as a valuable resource that needs to be managed and optimized through smart design choices.

LEED SCORE CARD - PLATINUM Sustainable Sites Water Efficiency Energy & Atmosphere Materials & Resources Indoor Environmental Quality Innovation in Design Location & Linkage Awareness & Education TOTAL

18 12 23 8.5 16 6.5 10 3 97

This eight-storey-tall, 72-suite condo was the first new construction condominium built in this walkable, vibrant and eclectic north end neighbourhood of Halifax. Its trendsetting industrial-looking balconies and colourful aluminum, stainless steel and zalmag cladding (made from recycled material) show that a building can be beautiful, as well as functional.

A total floor area of approximately 9,400m2 makes Q Lofts one of the largest multi-unit residential buildings in Canada to achieve Platinum status, and the only one of its kind in the Atlantic Provinces.

The building envelope features highly insulated ICF walls with R-values over R29, triple-glazed low-E argon windows, and thermally broken balconies; all to ensure minimal heat loss and a comfortable living environment throughout the year.

An innovative high efficiency air source heat pump system heats and cools the building using a high mass radiant floor distribution system, and the system heats domestic water as well. A highefficiency rooftop energy recovery ventilator with high MERV air filtration is constantly delivering fresh outdoor air to the

suites and common areas. Combined with low-VOC hard flooring and paint, and formaldehyde-free cabinetry and trim, Q Lofts has superior air quality.

Rainwater for use in toilets is collected from the building’s roof and stored in the 45,000-litre cistern under the garage floor, vastly reducing the load on the municipal water supply. Q Lofts also has low-flow fixtures and an exterior native foliage landscape requiring little-to-no irrigation.

LED lighting throughout the building, motion sensors in the garage and mechanical rooms, and EnergyStar rated appliances, bathroom exhaust and ceiling fans all reduce electrical consumption.

The icing on this Platinum cake is the impact these leading-edge and thoughtful energy efficiency measures have had on the Owners at Q Lofts: they enjoy the lowest condo fees in Halifax – by a wide margin.

4711 YONGE

4711 Yonge is a leader in sustainability, pursuing the highest standards of social, employment, and environmental practices, striving to make the community in which it operates a better place to live and work.

4711 Yonge has not only proven to be a consistently high-performing building, but it has continued to raise the bar for sustainability best practices. It initially achieved LEED Canada EB:O&M Silver certification in 2013, and has now upgraded to LEED Canada EB:O&M Gold, a remarkable achievement for a suburban office building.

Over the past 10 years, 4711 Yonge has implemented an Energy reduction strategy to dramatically cut energy consumption and decrease associated GHG emissions.

EUI has decreased by 31% while the ENERGY STAR score increased dramatically from 45 to 89, a major feat for a building that is over 30 years old. These significant energy reductions were not through a single upgrade but through strong leadership at the property, and a continuing drive to improve performance. With a strong commitment to sustainability, the building has made significant cuts to energy, water, and resource consumption while setting an industry example for implementing well-being initiative for its occupants.

Additional certifications and accolades include: BOMA Certificate of Excellence, BOMA BEST Platinum, Fitwel Certification, ENERGY STAR Certification and Wiredscore Gold Certification (2018). This impressive 30-year-old building continues to stand the test of time, keeping pace with towers half its age.

Built in 1984, this iconic AAA tower located in the heart of Vancouver’s downtown business district is well known for its pink granite façade and copper-glazed windows.

It is also a clean giant with LEED Gold and BOMA BEST Platinum certifications.

In 2018, it was awarded ENERGY STAR certification, one of the first buildings in Canada to do so.

This technology makes it possible to heat the entire building solely with the heat recovery chillers when outside air temperatures are above 7°C. An important goal for QuadReal is to improve and invest in existing buildings so that they remain competitive with new commercial properties, while creating comfortable environments that enhance the lives of tenants and guests. Park Place is proof that older buildings can meet and exceed the performance of new ones.

Driven by long-term financial and environmental considerations, many successful energy upgrades have taken place at Park Place. The latest was the installation of a heat recovery chiller that allows waste heat from cooling systems to be captured and re-used to heat other parts of the building.

101 MCNABB STREET, MARKHAM 101 McNabb Street is a 1980’s vintage office building owned by Op Trust Office Inc. and managed by Crown Property Management Inc. The 315,000 sq. ft., 3-storey building, occupied by General Motors (GM) and TD Bank, was renovated in 2015 from a single-user building to accommodate a multi-use tenancy.

An ASHRAE Level II Energy Audit resulted in adjustments such as optimizing the operating hours of the air handling units, upgrading controls of the cooling plant, and replacing exterior lights with LEDs. The building has an impressive EUI of 23.7 ekWh/sf, helping it to achieve an Energy Star score of 86.

Moreover, Crown has reduced the building’s EUI by 45% since 2014 through upgrades to building systems and scheduling, and by working with its tenants to implement local occupancy and daylight control strategies and use of low power tenant equipment. The building provides 66 solar-powered electric vehicle charging stations for GM’s Canadian Technical Centre, and a private shuttle service to transit hubs.

ROYAL VISTA EMERGENCY SERVICES STATION Serving a number of communities in Calgary’s northwest, this 4-bay, 23,680 sq ft multi-services facility provides a number of essential services to the area. The building faces the main industrial community thoroughfare acting not only as a gateway along the ‘community route’, but also serves as a civic destination for community activities.

2018

The building design responds to the prairie style design guidelines established for the industrial park and showcases a rain garden as a demonstration of stormwater management techniques. The building, which certified LEED Gold, is centered around shared services and operational functions.

The building employed a complex series of sustainable initiatives to reduce the building’s dependency on the city’s utility infrastructure, effectively reducing the overall capacity needs of a fire station down to that of a large house. This resulted in significant reductions in potable water use, reductions in effluent volume needs, and storm water management impact on city storm sewers. The building also includes the use of solar panels, LED lighting, solar tubes, light shelves and efficient mechanical systems all contributing to an overall reduction in energy consumption.

Planned, designed and constructed to accomodate the MNRF’s demanding staff, training and first response needs, this facility consolidates all Northeastern operations under one roof.

Interior space planning of the building is sensitive to airside and groundside operations typical of airport facilities with administrative and training spaces generally separate from warehouse, storage and service-type spaces. Office, administrative and training spaces capitalize on natural light views to the exterior and solar heat gain in the winter months, with generous roof overhangs sheltering these spaces from the unwanted heating effects of the summer sun. The building’s mechanical system design incorporates numerous heating and cooling zones allowing for maximum temperature control relative to building occupancy as it fluctuates seasonally between peak summer months and the firefighting low season.

The Civic Centre Resource Library (CCRL) received LEED Silver certification in June 2018. The 3,306-square-metre building was designed to promote literacy, community outreach and environmental stewardship through its expansive views, open space design and interior courtyard. The library is home to more than 70,000 books and provides services to 20,000 residents every month by offering amenities such as a study hall, reading lounge, computer lab, children’s area, creative suite and an upper reading patio with access to natural lighting.

The CCRL was constructed with a high albedo roofing system and efficient LED and motion sensor lighting that helps conserve energy when rooms are unoccupied. It features mechanical and electrical systems that control ventilation and variable speed fans to ensure efficient operation; and high-performance glazing that reduces solar heat gain and glare. These energy efficient measures, among others, are projected to reduce energy consumption by 33 per cent.

Water is conserved through low flow plumbing fixtures that reduce the amount of potable water consumed by 37 per cent, in addition to drought-tolerant landscaping and native plants that require little to no water. The building’s waste reduction efforts include refillable water stations and the adoption of recycling services.

This successful project promotes active and sustainable transportation by offering bike racks, two electric vehicle charging stations and easy access to public transit, including York Region Transit, TTC bus routes and Maple Go station.

A comprehensive education outreach program was developed that includes a guided tour of the building which identifies key design features that improve the overall environmental impact of the project.

The building is also included on the City of Vaughan’s Green Buildings website.

CHARTING NEW TERRITORY IN PASSIVE HOUSE

Clayton Community Centre

Located in Surrey BC, the Clayton Community Centre combines three key uses: a visual and performing arts centre, a community library and a recreation centre.

The design approach for the project was to move beyond simply co-locating these centres and instead truly integrate them into a single community building.

By Melissa Higgs, HCMA Architecture + Design

From the beginning of the schematic design, the design team came to understand that meeting Passive House objectives would significantly affect the building’s form and layout.

Developed from those assumptions, the first PHPP model caused the design team to realise that the challenges this project was going to encounter—namely the high cooling loads and Primary Energy Renewables—were different than any typical residential Passive House project.

Custom radiant panels, which have good compatibility with natural ventilation, were integrated into the ceiling by running the heating and chilled water pipes through q-deck flutes and pockets within the roof insulation.

To reduce these loads, the thick building insulation layer typically prescribed for Passive House projects required re-evaluation. Lowering the overall R-value of the envelope increased transmission heat losses, but not enough to reach the target of 15 kWh/m2yr for cooling loads. The addition of a passive natural ventilation system combined with strategic solar shading brought the heating and cooling loads into balance and in conformance with Passive House requirements.

REVOLVING DOOR The high occupant turnover in the facility was identified as a challenge not only due to the internal loads they present, but also due to the resulting infiltration caused by door openings.

The project’s fast-track delivery method necessitated a significant overlap in the design and construction phases. Utilizing prefabricated precast concrete elements for the façade became a key consideration, not only for ensuring long-term durability and reduced maintenance, but because it also enabled the building to be closed in quickly to meet the tight construction schedule.

As a result, SE3P’s compelling architectural expression is a unique façade composed primarily of framed alternating strips of energy-efficient, undulating precast concrete double wythe insulated panels and reflective glazing. Drawing inspiration from the geometric pattern of electrical circuit boards, the precast concrete panels also symbolize the technological subject matter that will be taught within the building.

By fabricating the exterior finish, thermal and moisture protection, and interior finish off-site as a single pre-assembled system, the project’s schedule, performance and energy-

saving goals were maintained while mitigating on-site construction noise and debris. The heavier precast concrete elements with reflective glazing help to animate the façade and are juxtaposed with the transparent glazing at the building’s ground plane which extends the outdoor public realm into the interior public space, engaging the local community.

The focal space in the building is the five-storey central atrium, which receives daylight via clerestory glazing, and provides indirect daylighting throughout the core of the building. Skylights provide indirect daylighting to the ground floor teaching labs along the north side of the building and to offices on the fifth level.

Daylight sensors are provided to dim or switch off artificial lighting in the atrium, reducing power consumption when natural lighting levels permit.

The atrium employs in-floor radiant heating and cooling in the ground floor slab. In this space, where solar gains and glazing heat losses are greatest, this takes advantage of the large thermal mass of the building to achieve optimal thermal comfort during peak design conditions in both heating and cooling periods.

The atrium is used as a large return air plenum with fan-assisted relief air at the mechanical penthouse level, taking advantage of the stack effect. Air handlers are sized for low velocity air flow through the filters and coils to reduce the overall building fan power.

12 10 The return air from the clean office/classroom/administrative side of the building is re-used and mixed with outdoor air at the Laboratory air handling equipment, achieving 100% heat recovery. Air quality monitors reduce air supply to the laboratories by as much as 50% during normal operations. Should air quality issues arise, air supply to the affected laboratory is automatically increased to ensure occupant safety.

The building heating systems are connected to the City of Surrey’s district energy system, and are supplemented by a large run-around loop on the laboratory air handling system, which reduces heating by up to 60%.

An open loop cooling tower directly connected to magnetic bearing centrifugal chillers is used to optimize overall energy use, with a free cooling heat exchanger for winter time cooling loads within the building.

With these energy saving measures and a wide range of other sustainable design strategies, the SFU Sustainable Energy and Engineering Building is targeting LEED Gold certification, and at the same time adding a new landmark structure to Surrey’s rapidly growing city centre.

PROJECT NEXTUS Architectural firm’s own office demonstrates sustainability on a smaller scale Located in Saskatoon, one of the youngest and fastest growing cities in Canada, our new workplace had to embody a fresh identity and a progressive environmental agenda.

By Bertrand Bartake In a province where sustainable design is not yet the norm, we wanted to lead by example. Project Nextus is in line to become the first LEED Platinum certified project in Saskatchewan. Located in a main floor storefront space, it puts active design principles on public display.

We established ambitious sustainability goals with an emphasis on staff health and comfort. We met those goals by planning and intelligent design first, and then by including technology if necessary. It was important for us to create an environment of choice for staff while inspiring creativity.

One of the main elements of the design solution is a locally fabricated parametric perforated steel ribbon that acts as a wayfinding element and connects the two levels of the workplace by framing the central circulation. The ribbon acts as an acoustic absorber and screens the main mechanical distribution before morphing into a magnetic and writable surface for the meeting areas. The collective

efforts toward smart planning, functionality and ingenuity resulted in a workplace that is a manifestation of our core principles of context, collaboration and sustainability.

Large north-facing windows on the storefront provide abundant daylighting to the front of house spaces without the detrimental effects of glare. On the south side, a deep overhang enabled the design team to expand the area of glazing originally proposed for the base building, greatly increasing the daylight reaching the space. The use of 100% LED fixtures resulted in a power density improvement of more than 35% over the ASHRAE benchmark.

Occupancy sensors throughout, including on task lights, further reduce the power consumption within the space.

Staff are offered a variety of ways to work, with sit-stand stations, fully adjustable accessories, and task lighting. Staff also opted for a reduction in personal workstation space in exchange for more collaborative areas.

The plan balances open studios with focus rooms and a variety of shared meeting zones of different scales and functions. The studios are supplemented by floor-to-ceiling “Process Walls” which are both writable and magnetic, creating opportunities for display and collaboration. A postoccupancy survey helped fine tune the workplace for staff.

We wanted a space that would be both durable and adaptable to changes in staffing and evolving workplace needs. We targeted a minimalist material palette with emphasis on low maintenance materials while choosing flexible systems for the workspaces. The studio environments are reconfigurable to provide workspace for the company’s medium and long-range growth scenarios. The furniture systems and lighting can be adapted to suit new layouts.

To this end, we created seven sample layouts that utilized the same furniture components reconfiguring them to provide workspace for the company’s medium and long-range growth scenarios. The lights were specified with extra whip length so building operators could move the lights within the ceiling grid to suit revised layouts. The partitions for

continues to guide our outreach efforts. The project has been presented at numerous conferences and staff have volunteered their own time to participate in Doors Open Saskatoon. As an interior targeting LEED Platinum certification, the project endeavors to set a new benchmark for workplace design in the province, while demonstrating that sustainability can be accessible even to small businesses.

New (Temporary) Home of the House of Commons HIDDEN SOLUTION CONTROLS A GLARING PROBLEM

Any long-term renovation project comes with issues, and the recent conversion of the West Block courtyard in Ottawa to the new home of the House of Commons for the next 10 years, is no exception. In this case, a hidden solution was found to one of the most glaring problems.
