by jbs012210b3 — January 27, 2010—New guidance for achieving enhanced indoor air quality (IAQ) is available from five leading building industry associations and the U.S. Environmental Protection Agency. The book and CD provide strategies needed to achieve good IAQ using proven technologies and without significantly increasing costs.
The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a collaboration between ASHRAE, the American Institute of Architects (AIA), the Building Owners and Managers Association (BOMA) International, the U.S. Environmental Protection Agency (EPA), the Sheet Metal and Air Conditioning Contractors of North America, and the U.S. Green Building Council (USGBC).
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.
The guide includes these tips on improving IAQ in buildings:
- 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 O&M is essential to long term IAQ, and provide the access, training and documentation needed to facilitate O&M; and
- Commission from design through occupancy to ensure that IAQ objectives are met.
A summary document of the IAQ guide ideal for a general understanding of the importance of major IAQ issues can be downloaded for free from ASHRAE. The full publication complete with a CD that contains detailed guidance essential for practitioners to design and achieve good IAQ is available in hard copy or electronically for $29.
