2009 – Best Tall Building in North America, Council on Tall Buildings and Urban Habitat
Completed in 2009, the22-storey Manitoba Hydro Building houses more than 2,200 Manitoba Hydro employees. To help Manitoba Hydro set an example, the project team targeted a 60% reduction in energy consumption compared to the Canadian Model National Energy Code for Buildings. The project eventually achieved a 70% reduction.
North and south atria with staircases are active parts of the work environment. The south atrium consists of three stacked six-storey-high spaces while the north atrium rises to three storeys. The atria act as solar collectors, air handlers and air shafts.
The project included large contiguous column-less floor plates with raised floor access flooring, exposed concrete ceilings and exposed concrete corewalls.
Challenge: Manitoba Hydro stipulated a highly sustainable design.
Solution: High floor-to-floor heights and narrow floor plates optimize daylight penetration, thus reducing lighting requirements. A green roof and water feature in the south atrium provide humidification and dehumidification. Exposed radiant concrete ceilings maintain building temperatures. During winter, a geothermal heat pump system for ground heat exchange extracts heat from the ground to heat the building. In the summertime, heat extracted in the winter is returned to the ground to cool the building.
