ReNü Engineering Inc. is a five-person professional engineering firm with offices in Edmonton and Yellowknife. We are licensed to practice in Alberta, British Columbia, the Yukon Territory, the Northwest Territories, Ontario, and Nova Scotia.

We focus on the delivery of new buildings and the retrofit of existing buildings to high performance standards in Canadian climates using a technical approach that blends the disciplines of mechanical engineering and architectural science, the two disciplines responsible for most energy consumption in buildings.  ReNü believes that the success of high performance building projects lies in a truly integrated assessment and design process; the right design and construction players must communicate effectively from beginning to end. ReNü has supplied assessment and design services to over 550 high performance building projects across Canada, since incorporation in 2011.
