ASHRAE says its flagship energy standard is available for free download at the association’s website. The American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 90.1 “Energy Standard for Buildings Except Low-Rise Residential Buildings” is being offered as a free downloadable PDF

“Standard 90.1-2007 is widely used throughout the design community, and the download version makes it available to users at their own computers for ready and easy access,” said ASHRAE President Lynn G. Bellenger. “Making the standard available for free ensures that it penetrates the marketplace and reaches owners, contractors and design teams. We appreciate the support of the Department of Energy in reaching a wider audience and extending access to our flagship energy conservation standard.”
