Through a series of publications focused on energy optimization, four industry groups and the U.S. Department of Energy are providing guidance to help move the building industry toward market-viable net-zero energy and carbon-neutral buildings. Over the last decade, ASHRAE (which changed its name from the longer American Society of Heating, Refrigerating and Air-Conditioning Engineers) has published 10 separate Advanced Energy Design Guides (AEDGs) for six different building types. The first group of guides, published in 2005 (and with nearly 600,000 downloads to date), targeted a 30 percent savings beyond ASHRAE Standard 90.1-1999 and covered small offices, small retail, K-12 schools, small warehouses, highway lodging, and small hospitals and healthcare facilities. The most recent group of guides, published in 2013, targets a 50 percent energy savings over ASHRAE Standard 90.1-2004 and covers small-to-medium offices, medium-to-big-box retail, K-12 schools, and large hospitals. A 50 percent savings AEDG for grocery stores is now in development.
