Manitoba Hydro Place is a 23-storey, energy-efficient building on Winnipeg's Portage Avenue that took 3.5 years to complete, $300 million.

A Winnipeg skyscraper designed by Toronto and Winnipeg architectural firms has won the Council on Tall Buildings and Urban Habitat's 2009 award for the best tall building in the Americas.

Manitoba Hydro Place, which opened its doors to employees last December, was a joint venture between Kuwabara Payne McKenna Blumberg Architects of Toronto and Winnipeg's Smith Carter Architects and Engineers Inc. 

Prairie Architects Inc. of Winnipeg served as the client's consultant on the project.

The 23-storey, energy-efficient building on Winnipeg's Portage Avenue took 3½ years to complete at a cost of $300 million.

The building uses geothermal heating and radiant cooling that makes it one of the most energy-efficient office towers in the world.

Based at the Illinois Institute of Technology in Chicago, the CTBUH is the world's leading organization on tall buildings.

Its annual awards recognize outstanding buildings in four geographical areas: the Americas, Asia and Australia, Europe, and the Middle East and Africa.

According to its jury award statement, Manitoba Hydro Place "was designed to be completely site specific. The design could not be transplanted to another city and still work, thus making it the perfect response to the seeming homogenization of the world's skylines."

The award will be conferred at the organization's annual awards dinner in Chicago in October.
