Winnipeg Firm wins First International Green Roof Award.

Number Ten Architectural Group of Winnipeg has won the first annual International Green Roof Award of Excellence for its work at Ducks Unlimited Headquarters at Oak Hammock Marsh Interpretive Centre. The green roof recreates a prairie grass habitat that attracts wildlife and reduces heating and cooling loads as well as storm water runoff as the plants act as retention vehicles that hold rainwater and release it through evaporation. Number Ten, one of the first architectural firms in the province of Manitoba to certify in the Leadership in Energy and Environmental Design (LEED) program, received the award last month at a ceremony in Chicago.
