Best Practices for Maintaining IEQ
The recommended best practices for maintaining a high quality
indoor environment vary throughout the world; however, there are
several widely accepted elements of best practice. This section describes
best practices that are widely accepted as beneficial.
5.1 MAINTAINING GOOD INDOOR AIR QUALITY
5.1.1 Limiting Pollutant Emissions from Indoor Sources
1 Limiting the rates of pollutant emission from indoor sources is
essential to cost-effectively maintain good IAQ. While the rates of
pollutant emission from occupants are not generally controllable,
emissions from many other pollutant sources can be minimized
by adhering to the following practices. Tobacco smoking should
be restricted to enclosed and depressurized^1 smoking rooms from
which air is exhausted to outdoors. Alternately, indoor smoking
should be entirely eliminated.
2 Building materials, furnishings, office equipment, and cleaning
and pest control products and practices with low VOC and odor
emission rates should be selected. In general, however, selection
of low-emitting products is a difficult task because of limited
information on VOC emissions, the lack of standard methods
- Smoking rooms should be maintained depressurized relative to adjoining
rooms.
