Energy Efficient Retrofits

New buildings account for a relatively small percentage of the energy used in the building sector. Retrofitting existing housing and commercial/industrial facilities is an important goal in terms of energy savings. It is also a complex endeavor, with many factors to consider, from preserving historic features to controlling costs.

The following articles and reports discuss a wide variety of materials, situations and techniques that may be encountered when undertaking an energy-efficient retrofit. As well, many case studies are provided to illustrate how to do retrofits right.
