Risk Management Indoor Air Quality (IAQ) Tailoring Lease Specifications www.saif.com

stringent standards to buildings occupied by state employees during normal working hours. These standards shall be applied ... to buildings for which the State enters into new leases following the date in this subsection.” ASHRAE Standard 55-2004 provides information describing acceptable operative temperature and humidity, therefore reference to this Standard provides for the specification of temperature and humidity conditions.

Another documentation of the performance capability of the HVAC system, in addition to that specified in Clause #1, is measurement of the total air handling volume, the amount of indoor air entering the HVAC system and the distribution of conditioned air to the occupied spaces.

Clause #3:

Prior to occupancy, a validated report detailing the measurement and verification of air volume testing, adjusting and balancing shall be provided.

This could be performed by a contractor certified National Environmental Balancing Bureau (NEBB) or by a building representative. For spaces which have been previously occupied, building maintenance personnel are likely to conduct balancing.

Air Contaminant Sources

The major factors that affect the potential of materials to contribute air contaminants, principally volatile organic chemicals (VOCs) can be summarized as follows:

  • 1.

    The quantity and distribution of the material in the building (i.e. floor coverings, work surfaces and interior partitions which are all significant because of the large extent of their use).

  • 2.

    The specific chemical composition of the products.

3. The stability of the chemical substances involved.

4. The toxic or irritation constituents involved.






Standards do not yet exist to provide a yardstick for specifying limits in new materials. This is a new area and more information is becoming available slowly. Currently information is available from manufacturer’s Material Safety Data Sheets (MSDSs) which list hazardous substances contained in the products they cover.

However, although MSDSs are available for most building products, their usefulness in this application is debatable due to “trade secrets” exemptions in the reporting requirements. The Environmental Protection Agency (EPA) is now developing a
