HVAC in a building in some ways can be compared to the pulmonary system in the human body. HVAC allows for the exchange of air throughout a building. The HVAC regulates temperature and comfort for occupants. As system components age they can degrade and affect performance. Therefore, preventative maintenance improves IAQ and energy efficiency. The […]

By Dr. Rajiv Sahay, CIAQP, FIAS, Director of Environmental Diagnostics Laboratory Indoor Air Quality (IAQ) and the health of the indoor environment has been a rising concern in recent years from the health, hygiene, and productivity viewpoints. Individuals are exposed to a number of allergens or contaminants on a continuous basis. These contaminates/allergens can cause […]

Jointly published by the Continental Automated Buildings Association (CABA) and Environmental Diagnostics Laboratory (EDLab) at Pure Air Control Services, Inc, this study takes a close look at how human skin cells can affect the health of the indoor environment. Human Skin Cells: A Potential Source of Building Contaminates was made public in July of 2018. It […]

Indoor air quality investigations are often initiated by occupant complaints to the facility manager of a building. These grievances are generally manifest through sight, smell and actual physical conditions only present when the occupant is in the questionable indoor environment. A building scientist who is sent to collect samples and log data for an IAQ […]
