Grid-Interactive Efficient Buildings Technical Report Series: Windows and Opaque Envelope: U.S. Department of Energy (DOE), Energy Efficiency & Renewable Energy (EERE)

Through its grid-interactive efficient building (GEB) research, the U.S. Department of Energy (DOE) Building Technologies Office (BTO) seeks to build on existing energy efficiency efforts and develop technological capabilities to optimize the interplay between building loads and the electric grid. This report focuses on dynamic window and opaque envelope technologies. Dynamic building envelope technologies include, for example, electrochromic glazing, automated attachments, and thermal storage. These technologies are in contrast to static high-performance building envelope technologies, such as highly insulating windows.
