Indoor Air Quality (IAQ)
IAQ in Large and Commercial Buildings
Indoor air quality (IAQ) problems are not limited to homes. In fact, many office buildings have significant air pollution sources. Some of these buildings may be inadequately ventilated. For example, mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air. Finally, people generally have less control over the indoor environment in their offices than they do in their homes. As a result, there has been an increase in the incidence of reported health problems.
ASHRAE Indoor Air Quality IAQ Design Guide Now Available for Free
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) is now making the IAQ design guide and all of its reference materials available to the public at no cost through its website.
The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is designed for architects, design engineers, contractors, commissioning agents, and all other professionals concerned with indoor air quality.
The Guide was developed in cooperation with the American Institute of Architects, The U.S. Green Building Council, the Builders and Owners Management Association International, the Sheet Metal and Air Conditioning Contractors of North America, and the U.S. Environmental Protection Agency.

Developed by the Lawrence Berkeley National Laboratory with funding support from EPA, the IAQ Scientific Findings Resource Bank is a resource for public health professionals, building professionals, and others who seek scientific information about the effects of IAQ on people’s health or work performance.
The IAQ Scientific Findings Resource Bank provides information summarizing the state of scientific knowledge about the relationships between people’s health and productivity and the IAQ conditions or associated building characteristics in which the people work or reside. This website also provides links for downloading published journal articles that were developed under the project. Learn more at www.iaqscience.lbl.gov

Homeland Security and the Indoor Environment
In 2002, the Office of Homeland Security (OHS) formed the Interagency Workgroup on Building Air Protection which includes representatives from agencies across the Federal government. EPA is the Executive Secretariat of this Workgroup which is chaired by OHS. One of the first tasks of the Workgroup was to produce guidance to building owners and managers that would contain a set of recommendations they could implement now to better protect the indoor environments of their buildings from terrorist threats.
