ATLANTA - A new guide for achieving enhanced IAQ in buildings is now available from five leading building industry associations and the U.S. Environmental Protection Agency (EPA). The new book and CD is said to provide strategies to achieve good IAQ using proven technologies without significantly increasing costs.

“The health and comfort of buildings occupants is too important to leave IAQ as an after-thought in design, construction, and operation,” said Andrew Persily, Ph.D., chair of the committee that wrote the new guidance. “There is plenty of experience out there to help avoid IAQ problems in buildings, allowing all of us to breathe a little easier.”

The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a collaboration between the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the American Institute of Architects (AIA), the Building Owners and Managers Association International (BOMA), EPA, the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA), and the U.S. Green Building Council (USGBC).

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

Some of the tips from the guide include:

• Bring IAQ into the very earliest design discussions. Don’t get stuck retrofitting the design for IAQ at the end of the process

• Strictly limit liquid water penetration and condensation in the envelope, and control indoor humidity.

• Where outdoor air quality is poor, use enhanced filtration and air cleaning to provide high quality ventilation air. Locate outdoor air intakes away from contaminant sources and provide the means to measure and control minimum outdoor airflows.

• Select building materials and furnishings that have low contaminant emissions and don’t require use of high-emitting cleaning products.

• Exhaust contaminants from indoor activities as close to their source as possible.

• Recognize that operations and maintenance (O&M) is essential to long term IAQ, and provide the access, training, and documentation needed to facilitate O&M.

• Commission from design through occupancy to ensure that IAQ objectives are met.

A summary document of the Indoor Air Quality Guide, which provides a general understanding of the importance of IAQ issues, can be downloaded for free at www.ashrae.org/iaq. The full publication complete with a CD that contains detailed guidance is available in hard copy or electronically for $29.
