ANSI/ASHRAE Standard 55-2010 Newly Published
November 30, 2010

New requirements regarding air speeds, analysis and documentation are included in the newly published American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) thermal comfort standard, ANSI/ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy.

The standard specifies the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space.

The 2010 version of the standard also includes improved and expanded graphics that better guide users of the standard in simple applications. Improvements to the SI and IP versions of the traditional “comfort zone” chart include enlargement, clarification and notes to aid users of the standard.

Standard 55 combines Standard 55-2004 and the 10 approved and published addenda to the 2004 edition into one easy-to-use, consolidated standard.

The cost of Standard 55 is $69 ($59, ASHRAE members). To order visit www.ashrae.org/bookstore.
