APPCD Branches
The Indoor Environment Management Branch (IEMB). IEMB is part of the EPA's National Risk Management Research Laboratory (NRMRL), Air Pollution Prevention and Control Division (APPCD), and is located in Research Triangle Park, NC.
Research conducted by IEMB has been the basis for developing a better understanding of the relationship between indoor air quality (IAQ) and emissions sources, heating, ventilating, and air-conditioning (HVAC) systems, and air cleaning devices. The results of our research can ultimately provide practical methods that architects, design engineers, builders, manufacturers and suppliers, and the general public can use in designing, selecting, operating, maintaining, and producing materials and building systems for improved IAQ.
Details of our research projects and published results can be found in the research areas and Publications pages.
