British Columbia's Energy Efficient Buildings Strategy established targets for significant energy and emission reductions in new and existing buildings by the year 2020. It promoted systemic market transformation through the introduction, adoption and eventual regulation of new energy efficient building designs, products and technologies, and ensures that demand-side management programs and government leadership, incentives and regulations lead to permanent changes in the market. This paper outlines key policy measures, estimates energy savings and identifies a framework for evaluating the Strategy's progress, including indicators of success. A quantitative analysis on current and planned energy efficiency measures indicated that the targeted 20% reduction in energy use per household can be met and that the 9% reduction in commercial and institutional energy use can be exceeded. The composition of savings was well-distributed across measures, with 38% relying on utility and government programs and rates and 50% from codes and standards.
