The Reducing Energy Waste with Heat Recovery fact sheet explains how passive heat recovery systems can capture waste heat from exhaust air, water, combustion gases, and other sources to offset building heating demands. It provides an overview of common heat recovery technologies, key design considerations, and recommissioning best practices to improve system effectiveness. By optimizing existing heat recovery systems, building owners and operators can reduce energy consumption, lower emissions, and improve overall building performance across a wide range of building types.

The fact sheet was prepared by Prism Engineering on behalf of Natural Resources Canada (NRCan).
