Harold Walter Orr, C.M.
Saskatoon, Saskatchewan

Harold Orr’s efforts have been integral to improving energy efficiency and conservation in Canadian homes. As a housing engineer with the National Research Council, he was a key driver of the Saskatchewan Conservation House project, which led to the establishment of new national energy conservation protocols for Canadian buildings. His innovations, which include new insulation techniques and materials, air sealing and efficient ventilation, blower-door testing and heat recycling, serve as worldwide models for energy-efficient housing.
