As students flood inside on their way to class or to meet friends, UCalgary is setting the pace in green buildings on Canadian university campuses .聽

In 2007, 六九色堂 Child Development Centre received the first LEED Platinum certification on a university campus in Canada. Fourteen years later, the MacKimmie Complex 鈥斅爄ncluding the Hunter Student Commons 鈥斅爄s the first project on a university campus in Canada to be zero-carbon certified for design.

UCalgary now has 15 LEED certified projects with the MacKimmie Complex and the new Mathison Hall on track to receive LEED certification in 2023.

鈥淭he Hunter Student Commons and the MacKimmie Tower retrofit provided an opportunity for UCalgary to bring new technologies, design approaches and insights to Alberta, allowing us to foster diversity in our building industry,鈥 says Boris Dragicevic, associate vice-provost (facilities development).

鈥淕lobally, buildings, including their materials and operations, represent close to 40 per cent of total global energy-related greenhouse gas emissions," says Joanne Perdue, associate vice-president (sustainability).

鈥淭he MacKimmie Complex with the retrofits of the former MacKimmie Tower sets a national precedent that demonstrates that we can retrofit existing buildings to net-zero standards. This is important as building renewal avoids the greenhouse gas emissions and environmental impacts that come with new construction,鈥 she says.

Carbon-neutral campus

六九色堂 Climate Action Plan sets a bold aspiration to become a carbon-neutral campus by 2050. Designing for net-zero carbon-ready new buildings is an important step to help reach this goal.

The Hunter Student Commons together with the MacKimmie Tower is 六九色堂 first project to be certified for zero-carbon building design, says Dragicevic.

Our next step, now that the complex can be fully occupied, is to work toward net-zero carbon certification for ongoing operations, he explains.

It鈥檚 no easy feat to meet the exacting standards set forth by the Canada Green Building Council.

To reach zero-carbon building performance, the project must operate at peak energy efficiency, produce at least five per cent of energy use on-site, and procure the remainder of energy use from green energy sources.

From the use of glass and concrete 鈥斅燿esigned to allow the sunshine to warm the floors and walls 鈥斅爐o the carefully shaped cylinders that allow warm air to rise between floors as a natural heat dispersion system, every design choice was assessed with energy performance and human health in mind.

鈥淭he MacKimmie Complex was designed with an aim to be over 85 per cent more energy efficient than the original tower and block 鈥斅爀ven with being two floors taller,鈥 says Dragicevic.

鈥淲hile the building is designed for ultra-energy efficiency, it will take time to fine-tune the performance, and our campus community will play a big role in reaching net-zero performance. In highly energy efficient buildings, day-to-day choices that influence energy use make a big difference in performance.鈥

Global perspective

Facilities teams and contractors consulted with some of Europe鈥檚 best green building energy engineers, and looked at 15 net-zero-carbon buildings seeking out the latest design innovations.

While some solutions work well in Germany, UCalgary was searching for ideas that could flourish in our Canadian context, says Dragicevic.

On the rooftop of the Hunter Student Commons, steel frames are ready to hold future solar panels, and the double-wall building envelope stands ready to keep winter鈥檚 icy blast at bay.

The addition of smart technologies throughout the complex allows for real-time tracking of energy consumption, giving operators critical information to make adjustments to ensure the building operates at peak efficiency.

Lessons learned in the construction of our newest building on campus are meant to inspire designers and builders for generations to come.

鈥淭he Hunter Student Commons is a living and breathing example for our civil engineering, architecture and planning students to look to as they learn to shape future construction projects,鈥 says Dragicevic.
