Guidance on ASHRAE Ventilation Standard

Spreadsheet, examples guide engineers through implementing ASHRAE Standard 62.1-2010.


The newest guidance for using Standard 62.1-2010 reportedly includes a revised, user-friendly spreadsheet and examples, as well as the latest updates pertaining to the new version of the standard.

The 62.1 User’s Manual provides explanatory material, detailed information, figures and examples to guide users in designing, installing and operating buildings in accordance with ANSI/ASHRAE Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, 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 significantly improved, made more user friendly and now includes two example spreadsheets focusing on cooling and heating.

“The spreadsheet and new examples have been revised in response to user feedback and have much improved usability,” Roger Hedrick, chair of the Standard 62.1 committee, said. “The spreadsheet should significantly reduce the effort needed to perform the calculations needed for multizone recirculating systems. The spreadsheets are a must have for designers.”

The Manual encourages users of the standard to apply the principles of good indoor air quality and effective ventilation when designing buildings and building systems, and provides useful reference material to assist designers in efficiently completing a successful and compliant design.

The cost of the 62.1 User’s Manual is $75 ($64 ASHRAE members). To order the manual, contact ASHRAE Customer Service or visit the ASHRAE bookstore.
