New 62.1 Procedure Focus of ASHRAE 2005 Course

By Consulting Specifying Engineer Staff May 23, 2005

ASHRAE members this summer will have the opportunity to learn about using the overhauled ventilation rate procedure in Standard 62.1, the focus of a short course at ASHRAE’s 2005 Annual Meeting in Denver next month.

The course, Complying with Requirements of ASHRAE Standard 62.1-2004 , will be held from 2-5 p.m. Tuesday, June 28. The rate procedure is one of many changes to ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality . Course instructor Hoy Bohanon, P.E., said the procedure makes it more straightforward for designers to determine rates and reduces the potential for over-ventilation in some densely occupied spaces.

“Using the procedure gives you a better balance,” he explained. “You get a more accurate balance of indoor air quality and energy efficiency by doing the more precise calculations.”

The procedure bases ventilation requirements on the number of people a space is expected to hold, as well as the space’s floor area, and is used to calculate minimum outdoor ventilation requirements for a building ventilation system.
