BFRL Contributes to NIOSH Guidance Document on Use of Filtration and Air-Cleaning for Protection of Building Environments

Andrew Persily of the Indoor Air Quality and Ventilation Group in the Building Environment Division contributed to the development of a document entitled Filtration and Air-Cleaning Systems to Protect Building Environments from Airborne Chemical, Biological or Radiological Attacks. The report, published by the National Institute of Occupational Safety and Health (NIOSH), was developed in cooperation with the Interagency Workgroup on Building Air Protection of the Office of Homeland Security (OHS). This workgroup, of which NIST is a member, was formed in January 2002 under the Medical and Public Health Preparedness Policy Coordinating Committee of the OHS and includes representatives from agencies throughout the federal government. The document discusses air-filtration and air-cleaning issues associated with protecting building environments from an airborne chemical, biological, or radiological (CBR) attack. Copies of the report, DHHS (NIOSH) Publication No. 2003-136, are available on the NIOSH Web site at www.cdc.gov/niosh. The NIOSH Web site also can be linked from the BFRL Web site (www.bfrl.nist.gov).

BFRL Releases Natural Ventilation Design and Analysis Tool

BFRL has developed a software tool to assist designers of natural ventilation systems in buildings. The tool, Loop Design and Analysis (LoopDA), is integrated with BFRL’s existing multizone airflow analysis program,
CONTAMW.

Prior to this development, designers were unable to perform the engineering analyses required for natural ventilation system design. This limitation was inhibiting the development and application of new natural ventilation technologies in buildings, which have the potential for increasing energy efficiency and improving indoor environments and occupant productivity. LoopDA implements the Loop Equation Design Method for sizing openings of natural ventilation in buildings, and allows direct consideration of the dynamics of stack and wind-driven airflows.

LoopDA is available for download from NIST at www.bfrl.nist.gov/IAQanalysis.
