Eighth Avenue Place
The 49-storey east tower of Eighth Avenue Place-the third-tallest building in downtown Calgary-boasts a number of environmentally friendly features, starting with the envelope.
A unitized curtain wall system with dual-pane glass that has solar screening coatings and thermally separated interior and exterior aluminum mullions prevents heat transfer. The mullion system was custom-designed and fabricated for the building.
Eighth Avenue Place also has a building management and control system that monitors the carbon dioxide level in the tower and the carbon monoxide level in the parking garage. When levels go higher than desired, air is brought in just until the level reaches the right point.
The system also monitors temperature and lighting. It will make automatic adjustments to ensure air quality and operators can make adjustments from a computer, in the building or remotely.
The first pre-certified commercial Leadership in Energy and Environmental Design Platinum high-rise in Canada, Eighth Avenue Place is also topped with what may be the largest green roof in the country. The 30,000-square-foot green roof mitigates the heat island effect in summer and retains and treats stormwater, reducing the amount of water discharged into the municipal stormwater system.
Other features include:
- Low-flow washroom components that reduce water use by 40 per cent.
- Low-emitting paints, adhesives and solvents.
- Environmentally sensitive refrigerants.
- 300 stalls of bicycle parking with adjacent showers.
Kim Rishel, manager of Sustainable Building Services, Western Canada, for EllisDon Construction says the sustainability of Eighth Avenue Place was a combined effort.
"It's that collaborative, integrated design process where you have everybody working together all the time," Rishel says.
Eighth Avenue Place is also noteworthy because it's the first high-rise building in Calgary since 1984 that consists of a concrete core with a structural steel frame. The core was poured using self-climbing formwork.
The entire project consists of the tower, a Plus 15 connected podium, a six-level parkade and a winter garden.
