The Manitoba Hydro Place

Manitoba Hydro Place is the headquarters building of Manitoba Hydro, the electric power and natural gas utility. Manitoba Hydro Place received LEED Platinum certification in May 2012, making it the most energy efficient office tower in North America and the only office tower in Canada to receive the LEED Platinum rating.
Opened as Winnipeg's 4th tallest building in September 2009, the 21-story office tower brought together 1650 employees from 15 suburban locations into one 695,000 sq ft (64,568 m2) high rise on a full, downtown block. With the design's plan view resembling a capital letter "A", the project comprises two 18-story twin wings framing three 6-story, south-facing atria (winter gardens).
In 2009, CBC News called Manitoba Hydro Place (MHP) one of "the most energy-efficient office towers in the world and the Toronto Star called MHP the "most important building in Canada."
