Commercial buildings consume 46 percent of all building energy in the United States. Most of those buildings—potentially as many as 70–80 percent—are owned as part of a larger portfolio of buildings and are managed by a central entity. This portfolio demographic provides a powerful lever for achieving dramatic energy use reduction in buildings, and RMI is counting on that lever to drive the U.S. toward reducing building energy consumption by 50 percent.
Until recently, most building portfolio managers saw and treated their holdings as a collection of individual buildings, cream-skimming energy measures opportunistically. Now, industry leaders are realizing that the entire portfolio is the asset and can be optimized more intelligently and more broadly to achieve deeper energy savings. The U.S. General Services Administration and the State of California are both modeling such portfolio approaches to energy management. Yet, guidance on this type of approach remains elusive … which is where RMI comes in.
RMI has developed a working approach to improving building portfolio energy management, which we are testing through our Portfolio Energy RetroFit Challenge. Engaged with AT&T and the Exchange, we have shaped our initial hypotheses into a viable methodology.
