A plan has been developed for assessing the air quality of non-industrial buildings. It consists of ten tasks. Tasks 1 and 2 are designed to obtain the background information on the building itself, its surroundings and occupants. Task 3 provides an opportunity for the project team to review theresults and to determine if an in-depth study is necessary. Tasks 4, 5 and 6assess the performance of the building's HVAC systems and identify the contaminants present.
