摘要

In the United States, HVAC systems generally consume the largest portion of a commercial building's energy budget, with supply, return, and exhaust fans accounting for approximately 1.25 quads-or roughly the equivalent of 225 million barrels of oil-of energy use annually (Figure 1). Expected in the fall, the 2013 version of ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, will include a new fan-efficiency requirement based on ANSI/AMCA Standard 205-12, Energy Efficiency Classification for Fans. This article explores the role fan efficiency plays in Standard 90.1, with specific attention paid to how the new fan-efficiency requirement will work with the standard's fan-power limitation.
