Potential savings in U.S. buildings sector by study

Tags


Beyond Reinventing Fire, there are many other studies assessing the U.S. efficiency potential. Despite differences in their assumptions, all studies conclude that the efficiency opportunity is significant and we must pursue it aggressively.

The conclusions of these studies should not be compared directly because their methodologies are so different. McKinsey, EPRI, and the National Academy of Sciences estimated the techno-economic potential. RMI also assessed the techno-economic potential but also made assumptions about the level of adoption for the Reinventing Fire vision. Note that the four studies consider adoption by a variety of dates. Broadly, RMI’s estimated savings are consistent with (if not below) the trendlines of other studies, except that RMI explicitly analyzes the integrative-design opportunities that NAS alone discussed but didn’t analyze.
