Energy efficiency in Canadian multi residential sector.

The energy efficiency of multi residential buildings in Canada has not kept pace with energy efficiency improvements in other commercial building sectors. Energy efficiency is subordinated to a dedication to reduce first cost of buildings in this sector. Lower first cost and energy efficiency are not mutually exclusive, however, building designers will have to learn to work together to achieve optimum results. The current practice and energy use of new buildings are reviewed in this paper. Suggestions for increased energy efficiency are explored together with their impact on first cost for the building.
