During the late 1970s and early 1980s, the State of California designed, built, and occupied a series of innovative, state-of-the-art, energy-conserving office buildings. Occupant complaints of indoor air problems in the first completed structure led to air quality monitoring in that building and two others prior to occupancy. Investigators applied a variety of measurement methods and protocols. Those investigations including air quality and ventilation system measurements are some of the results presented and discussed.
The results of the investigations were used to identify necessary remedial actions and to alleviate potential occupants' indoor air quality concerns. Ventilation system performance measurements were more useful than air quality measurements in identifying necessary remedial actions. Side benefits of these investigations were a “building closeout” procedure (indoor air quality and ventilation system evaluation guidelines) for new state office buildings, as well as an increased awareness of indoor air quality concerns among state personnel responsible for building design, construction and management.
