In support of recently installed 2013-14 President William P. “Bill” Bahnfleth’s presidential theme, which focuses in part on making buildings safe, healthy, productive, and comfortable environments in harmony with nature, ASHRAE is offering “Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning” as a free download.

First published in 2009, the guide provides strategies for achieving good indoor-air quality (IAQ) using proven technologies without significantly increasing costs.

The book describes 40 strategies for achieving IAQ objectives related to moisture management, ventilation, filtration and air cleaning, and source control and highlights how design and construction teams can work together to ensure good IAQ strategies are incorporated from initial design through project completion. Also, the book includes:

• Links to hundreds of internal and external resources.

• Tools for demonstrating the value of IAQ to clients.

The guide is the result of collaboration between ASHRAE, The American Institute of Architects, Building Owners and Managers Association International, the Sheet Metal and Air Conditioning Contractors’ National Association, and the U.S. Green Building Council, with funding provided by the U.S. Environmental Protection Agency.
