The Indoor Air Hygiene Commission (IRK) provides professional counsel to the president of the Federal Environment Agency on all matters of indoor air hygiene.

Recommendations and opinions

The members of this commission are appointed by the UBA President for a period of three years and come primarily from scientific institutions in Germany and various authorities at the Laender level. Membership in the IRK is honorary. In addition to appointed members, representatives from the Federal Ministry for Environment, the Federal Ministry of Health, Federal Ministry of Transport, Building and Urban Affairs, as well as the Federal Environment Agency itself attend its regular meetings. Other expert guests are invited as necessary.

The IRK develops recommendations and opinions on various issues and problems concerning indoor air hygiene. In the past, this has concerned for example tetrachloroethene in dry cleaning shops; household disinfectants; polychlorinated biphenyls; asbestos in storage heaters; asphalt floor panelling; and formaldehyde. Newer areas of focus include the occurrence of polycyclic aromatic hydrocarbons (PAH) after application of adhesives containing tar when putting down parquet panelling, hygiene problems of air conditioning and ventilation in buildings, microbiological indoor air pollution, and emissions from building products. The IRK has recently published several manuals.

The Commission’s areas of focus in the current session include proper ventilation in schools and particulates in indoor spaces.
