NIST/EPA study aims at healthy indoor climate.

The article reports that National Institute of Standards and Technology (NIST) analysis of a recent EPA survey of 100 representative United States public and commercial buildings found that actual post-construction ventilation conditions are often different than expected based on the building design. The NIST researchers said such findings highlight the importance of early testing of a ventilation system's ability to achieve design intent. They noted instances where building engineers could not find ventilation system plans or found the ventilation system equipment itself inaccessible and urged building designers and operators to remedy the situations.
