Best management practices (BMPs) for indoor air quality are procedures implemented during the planning, construction and operation of buildings to reduce exposure and emission of pollutants. For example, many building operators have established BMPs for maintenance (e.g., air-handling unit filter changes) intended to ensure good IAQ.
BMPs may require VOC sampling in order to determine suitable occupancy or re-occupancy timeframes (e.g., during renovations when VOC levels may be elevated due to the introduction of new materials or prior to occupancy). The appropriate VOC sampling method depends on the source-pathway-receptor scenario for each case. The methods would generally include screening or semi-quantitative methods when quick results and monitoring of control measures are required; and quantitative results when occu- pancy criteria or certification is required.
BMPs have been issued by various authorities, primarily by federal, provincial and municipal agencies. Examples are listed in Table 2-1.
