ATLANTA - A manual to help users navigate the changes in the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE’s) 2007 ventilation standard is now available.

The Standard 62.1-2007 User’s Manual provides users with a better understanding of the design, installation, and operation requirements in ANSI/ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality.

The standard, published last year, contains new requirements for separation of environmental tobacco smoke (ETS) spaces from ETS-free spaces, clarification of humidity control design requirements, and the inclusion of new rates for high-rise residential occupancies.

“The manual provides guidance for designers and contractors to clarify the requirements, explains why the requirements are included (in some cases), and how to comply,” said Roger Hedrick, vice chair of the 62.1 committee.

The cost of the user’s manual is $69 ($55, ASHRAE members). To order, contact ASHRAE Customer Service at 800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 404-321-5478, or visit
