This research study was undertaken to assess the impacts of building enclosure rehabilitations on the energy consumption of mid- to high-rise (5 to 33 storey) multi-unit residential buildings. The principal objectives of this study are to review and assess the actual energy consumption of in-service mid- to high-rise residential buildings, and the impacts of building enclosure rehabilitation related improvements on the overall energy consumption of these buildings. These findings are used to determine better building enclosure design strategies to reduce energy consumption and associated greenhouse gas emissions, while considering the other building functions for both new and existing buildings.

This project was sponsored by Canada Mortgage and Housing Corporation (CMHC), the Homeowner Protection Office, a branch of BC Housing, the City of Vancouver, BC Hydro, Terasen Gas (now FortisBC), and RDH Building Science as study partners.
