ATLANTA - Nearly 40 addenda and 16 American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards and guidelines are open for public review, which allows interested parties to comment on the technical guidance contained in the documents.

“Through the public review process, it is possible for anyone to provide input,” said Hugh McMillan, chair of ASHRAE Technology Council, which oversees standard development. “By opening the process to all interested parties during the public review period, it is hoped that through consensus, a final standard is published that has been rigorously examined, questioned, and defended. ASHRAE standards are strengthened by virtue of having been through this process.”

Addenda to the following standards are open for comment:

• ASHRAE Guideline 13-2000, Specifying Direct Digital Control Systems

• ANSI/ASHRAE Standard 15-2007, Safety Standard for Refrigeration Systems
