ATLANTA - The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has published a user’s manual for ANSI/ASHRAE Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, and another for ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings.

The Standard 62.1-2010 User’s Manual provides explanatory material, detailed information, figures, and examples to guide users in designing, installing, and operating buildings in accordance with Standard 62.1-2010, which sets minimum ventilation rates and other requirements for commercial and institutional buildings.

Also highlighted is the application of useful tools used for compliance with Standard 62.1-2010, including a newly revised spreadsheet that assists in Ventilation Rate Procedure calculations. The spreadsheet provides calculations for the multiple spaces procedure and has been improved, made more user friendly, and now includes two example spreadsheets focusing on cooling and heating.

Standard 90.1-2010, which provides minimum requirements for the energy-efficient design except low-rise residential buildings, contains 109 addenda approved since 2007.

The Standard 90.1-2010 User’s Manual provides detailed guidance on how to apply the latest ASHRAE/IES standard for the design of energy-efficient buildings.

“The new user’s manual is a very useful resource because it helps guide practitioners by explaining the intent of provisions in the standard and how they apply to buildings through not only written words, but also illustrations and example problems,” Steve Skalko, chair of the Standard 90.1 committee, said. “The latest edition of the manual is especially valuable because it specifically identifies what changes have taken place since the 2007 edition and through the use of calculations and examples tells how the new provisions apply.”
