There is vast, untapped energy savings potential in existing U.S. homes. With support from the U.S. Department of Energy, Lawrence Berkeley National Laboratory (Berkeley Lab) is conducting a research study to better understand the costs and challenges associated with deep energy retrofit (DER) projects. We are interested in DER projects that use a comprehensive, whole-home approach to drastically reduce energy use and improve performance. DER projects often aim at reducing energy use by 50% or more. In addition, these projects can improve home comfort and occupant health, and upgrade our housing stock for the next hundred years.
Yet, market adoption of deep energy retrofits (DER) has been limited. Major limiting factors include complex projects, high costs, perceived risks, extensive disruption, and unfamiliar work scopes to some contractors. In this study, we are looking for home performance contractors to submit cost data from past DER projects. We are also conducting a survey of the home performance market. Your contribution will help us broaden the adoption of deep energy retrofits and unleash the vast energy savings potential in existing U.S. homes.
This study has two parts:
- Deep energy retrofit (DER) cost breakdown
- Survey of DER market drivers, opportunities, and challenges
