ATLANTA - With 100,000 copies of its Advanced Energy Design Guide series now in circulation, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) estimates that it represents potential savings of $600 million in energy costs and 9 million tons of carbon dioxide. More than 88,000 of the publications have been obtained via free download since January.

The series includes publications on small retail and small office buildings, K-12 school buildings, and warehouses and self-storage units. The books provide guidance on how to achieve 30 percent energy savings over building code minimum based on ANSI/ASHRAE/IESNA Standard 90.1-1999.

Calculations indicate that if every guide downloaded resulted in a single building designed to save 30 percent beyond code minimum, the estimated energy and carbon savings would be 52 trillion Btu and 9 million tons of carbon dioxide. With an average cost of electricity of 5 cents per kWh and natural gas at $7 per MMBtu, the estimated cost of energy savings is over $600 million.

The guides are developed by ASHRAE, the American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IESNA), and the U.S. Green Building Council, with support from the U.S. Department of Energy. The free downloads are available at

“ASHRAE is committed to energy optimization and producing guidance that will help move the building industry toward market-viable net-zero energy and carbon neutral buildings,” said ASHRAE President Kent Peterson, P.E. “The call for these high-performing buildings is transforming our industry, and the guidance in the Advanced Energy Design Guide series is useable technology guidance to help owners, architects, and engineers in accomplishing high-performing buildings.”

“The green building movement offers an unprecedented opportunity to respond to the most important challenges of our time, including global climate change, dependence on non-sustainable and expensive sources of energy, and threats to human health,” said Rick Fedrizzi, president, CEO, and founding chair, U.S. Green Building Council. “Working with ASHRAE, AIA, and IESNA on the Advanced Energy Design Guide series is part of a critical collaborative effort to provide the industry with the tools it needs to make an immediate and measurable impact.”

Upcoming publications in the series include 30 percent guidance books for highway lodging, existing buildings, and small health care facilities. For more information on the Advanced Energy Design Guide series, visit
