indoor air quality

It is particularly important to be aware of the air flow pattern in a building when determining indoor air quality problems or calculating space conditioning loads for energy consumption. Correct sizing of space conditioning equipment is also dependent upon accurate air flow information. A number of infiltration models have been developed to calculate infiltration-related energy losses and the resulting air flow distribution in both single-zone and multizone buildings.

This report is the first in a series intended to assess residential air-pollution concentrations in the U.S. housing stock.

This paper covers some of the policy options used in the U. S. concerning regulation of building construction. The extensive code system is discussed, and the voluntary standards upon which the codes are usually based. While the codes set out the mandatory requirements, the standards are voluntary only. Some of the important background, research and philosophy of the standards are covered, as well as other information which has been offerred to users to promote the voluntary use of energy conserving strategies which are compatable with acceptable indoor air quality.
