ASHRAE Standard 62.1 User’s Manual–Based on ANSI/ASHRAE Standard 62.1-2019, Ventilation for Acceptable Indoor Air Quality
| Published By | Publication Date | Number of Pages |
| ASHRAE | 2019 | 144 |
This companion guide provides detailed information on the requirements of ANSI/ASHRAE Standard 62.1-2019 and includes tables, illustrations, and examples to aid users in designing, installing, and operating systems for ventilation in buildings. Standard 62.1 User’s Manual does not reproduce the requirements of the standard but rather paraphrases and elaborates upon them. Intended to be used in conjunction with the standard, this manual provides: • Information on the intent and application of Standard 62.1 • Sample calculations and examples • Best practices for applying the principles of good indoor air quality (IAQ) and effective ventilation when designing buildings and building systems • Useful reference material • Guidance for building operations and maintenance personnel • Instructions for the user in the application of tools used for compliance with ANSI/ASHRAE Standard 62.1-2019 Also included is an exclusive link to the recently revised Web-based spreadsheets that aid in ventilation rate procedure calculations. This manual is intended for architects, engineers, manufacturers, plan examiners, field inspectors, general and specialty contractors, and operation and maintenance personnel. Standard 62.1 User’s Manual is a crucial supplement for professionals concerned with ventilation and indoor air quality. Use it alongside your copy of ANSI/ASHRAE Standard 62.1-2019.
