ASHRAE Manual Is Revised, Available

September 29, 2008

ATLANTA - A revised user’s manual will assist users of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and Illuminating Engineering Society of North America (IESNA) energy conservation standard in energy efficient design.

The User’s Manual for ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, is now available. This manual has been through an extensive revision process to incorporate the various addenda approved since the 2004 edition according to Keith Emerson, who oversaw review of the manual for the Standard 90.1 committee.

Since the 2004 edition was published, 44 addenda have been approved and are now incorporated into the manual. Updates have been made to reflect and illustrate the changes in every portion of the 90.1 Standard. Appendix G changes have also been made.

“The Appendix G changes will be particularly useful to people involved with projects that are trying to achieve a certain amount of savings over and above the minimum requirements of the standard,” said Emerson.

The 90.1-2007 User’s Manual illuminates the standard by providing detailed instruction, calculation examples, and compliance forms for the design of commercial and high-rise residential buildings.

It includes sections on administration and enforcement, building envelope, HVAC systems, service water heating, power, lighting, the energy cost budget method, and the building performance rating method.
