A deep energy retrofit (DER) is a whole-building analysis and construction process that uses integrative design to achieve much larger energy savings than conventional energy retrofits. This presentation will cover the basic requirements of the Mass Save DER program as well as a review of some recent deep energy retrofit projects. We will work through the financial incentive structure that can be expected for a typical project and how to budget over the long term. We'll also discuss options for a partial DER that treats parts of the project immediately and leaves other areas prepared for future retrofitting when budgets are other conditions permit.
