Guidance on increasing energy efficiency in existing buildings is provided in a new book from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE); The American Institute of Architects; the Illuminating Engineering Society; and the U.S. Green Building Council, with support from the U.S. Department of Energy and assistance from Building Owners and Managers Association International and the U.S. General Services Administration.

“Energy Efficiency Guide for Existing Commercial Buildings: Technical Implementation,” the follow-up to “Energy Efficiency Guide for Existing Commercial Buildings: The Business Case for Building Owners and Managers,” is said to provide practical means and methods of planning, executing, and monitoring an energy-efficiency program.

The cost of “Energy Efficiency Guide for Existing Commercial Buildings: Technical Implementation” is $64 for ASHRAE members and $75 for non-members. Copies can be ordered by phone at 1-800-527-4723 (United States and Canada) or 404-636-8400, by fax at 404-321-5478, or online by clicking here.
