Making building performance a selling point, and moving on from the glass tower

By Richard Witt, Executive Principal, Quadrangle & Michelle Xuereb, Director of Innovation, Quadrangle

Sustainable building design is not a new concept. With the development and implementation of LEED in the early 1990s, sustainability became mainstream but has struggled to effect real change in the way we think about building performance, requirements or aesthetics. Economics and sustainable building design are at odds – sustainability is an extra cost, weighed against budget and relative value.

The Council of Tall Buildings and Urban Habitat concluded in their study Downtown High-Rise vs. Suburban Low-Rise Building that recently completed buildings significantly underperform in comparison to their counterparts from 50 years ago. The days of the glass skyscraper are coming to an end. Passive systems direct the way forward, as opposed to compensating for inefficiency with active systems.

Buildings are the key contributor and solution to climate change mitigation and adaptation.

According to the latest inventory release (2017) by The City of Toronto, 52% of GHG emissions in Toronto come from buildings, predominantly from burning natural gas to heat indoor spaces and water. Consequently, buildings must also be a climate change solution. The City of Toronto recognizes this in its Zero Emissions Building Framework, which is why the Toronto Green Standard (TGS) has us on a path to net zero buildings by 2030. What about the code? There is a plan to move Toronto to net zero by 2030, but it is not clear, given the current political climate, whether this proposal will be executed. Passive design solutions increase durability and climate change resilience while lowering energy usage, embodied energy from maintenance, and GHG emissions.

Passive solutions allow us to both mitigate and adapt to changing weather.

Based on the Climate Driver Study completed for the City of Toronto, we know that days are getting hotter, there are more of them and there are more of them strung together in heat waves. We are also experiencing larger storms, with heavier amounts of precipitation falling at once. The main issue we will have with our buildings is overheating and flash flooding – both in combination with power outages. This again reinforces the need for passive design solutions.

These power outages generally happen on our hottest and coldest days as a result of people cranking their AC or heating. The higher the total effective R-value of the building, the better they are able to maintain the indoor air temperature in the case of extreme temperatures without power.

The City of Toronto recommends that people be able to function independently for a minimum of 72 hours without power. In a residential building, maintaining indoor temperature is key to allowing people to shelter in place within their homes.

• At a basic level, a building is meant to shelter people from the weather – to keep people warm when it’s cold and cool when it’s hot. Glass is a very poor insulator, leaving residents feeling physically uncomfortable and paying high energy bills.

• As architects, the best thing you can do is reduce the amount of glass and increase the amount of well-insulated walls. We understand that keeping windows to about 40% of the wall area is the single most effective way to reduce the energy footprint of a building. Real walls with windows may seem old fashioned, but they don’t need to be. Our focus is on creating a thoughtful, well-designed building with an aesthetic that lends itself to real walls and windows.

• Unlike glass, insulation slows down the movement of heat. This allows you to hold onto heat during winter, making people more comfortable and more likely to actually use the spaces at the perimeter of their unit.


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.

Transparency Builds Trust

The traditional approach to redevelopment has been “design and defend,” where the developer finalizes a plan and then reveals it to the public. The trouble with design and defend is that it can spark resistance and resentment in neighbours and other stakeholders.

Rather than designing and defending, James Robertson, President &CEO for WCDT and his team   adopted a “transparency builds trust” approach.

Stakeholder Working Groups

The land that became University District is surrounded by five established neighbourhoods, the Foothills Medical Centre and it’s also home to the Alberta Children’s Hospital, the Ronald McDonald House and the University of Calgary. WCDT decided to establish relationships with all these stakeholders as early in the process as possible. WCDT recognized early on that you can’t just come into an area in the middle of established, well-loved communities and assume you can build whatever you want.

In redevelopment projects, the developer usually begins to meet the public as part of the land use re-designation application process. For University District, the public engagement project began well in advance of this stage, with a series of Stakeholder Working Groups. Each of these meetings, which functioned more like committees than open houses, focused on a single element of community design.

Each event included representatives from the surrounding communities and the main stakeholders, as well as the WCDT design team. This ongoing interaction was invaluable in building constructive relationships and helping to align the project goals with community needs. 

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.

Setting a Collaborative Tone

Next, WCDT held three open house meetings (the last of which was required by The City as part of the redevelopment application process). Breaking with tradition, each open house took place over two or three days, and in multiple locations to suit different stakeholder groups. Participants were offered different opportunities to participate, according to their individual preferences and schedules. WCDT considered it important to change the messaging from ‘the usual ‘Come to this open house to see what we’re doing,’ to ‘Come to this open house to see what we’re all doing.’

At the meetings, WCDT displayed large information boards, and participants placed Post-It Notes directly on these boards to indicate approval, concerns and/or disagreements. The WCDT team would then photograph the boards, compile all the feedback (positive and negative) and report it back to the participants and communities. These notes were also given to the WCDT design team to analyze and consider.

Recognizing that not everyone can attend meetings, and the opinions offered may not represent the views of everyone affected by the development, WCDT also posted an online survey, set up storefront information booths, and wrote letters directly to communities soliciting questions and comments.

This inclusive approach to engagement proved popular with the public. During the approvals process, all five surrounding communities submitted a letter to the City of Calgary expressing their support for the University District Plans – an unusual, perhaps unprecedented, expression of support.
