Abstract
This paper describes the development process for the new energy code. A key element of this process is the LCC procedure employed to determine the building envelope requirements. This procedure involved development of a simple regression model to predict heating and cooling energy; development of a computerized analysis procedure to permit rapid LCC analysis; identification of representative wall, roof, and window constructions along with the thermal performance characteristics and construction cost for each; consultation with the provinces and territories to determine appropriate energy costs and economic assumptions to use in the LCC analysis for each region; and an established process for developing national model (building) codes that achieves consensus through a balanced committee structure and extensive public review.
