This review explores opportunities to develop new energy efficiency standards for existing buildings in BC through the application of third-party model standards and codes. The objective is to improve the energy efficiency of existing buildings at the time of construction and thereby reduce energy consumption and greenhouse gas emissions. The application of energy efficiency standards to existing buildings also has the potential to contribute to a range of non-energy co-benefits, such as enhanced community economic development, resilience to climate change, and improved air quality and health. Implementation options are presented that align with the objectives of the Building Act and with the competency of building officials who enforce the code. The options also promote consistency and innovation within the building regulatory system.
This work has been sponsored by FortisBC and BC Hydro. It was developed in close consultation with a steering committee comprised of the Building and Safety Standards Branch and the Ministry of Energy and Mines. This document is not intended to serve as a regulatory proposal, but rather it provides background information and an analysis of key options to inform discussion with key influencers and stakeholders.
