Investigation

A thorough walk through inspection of each floor is conducted to investigate and determine potential sources of Indoor Air Quality contamination. The mechanical room air handling systems are visually inspected for microbiological contamination on the cooling and heating coils, drip pans and other system components. The maintenance records also are reviewed for each facility. Experienced field technicians qualitatively review the delivery capacities of the air handling systems to determine if air flow appears sufficient for the size and type building under investigation.

Indoor air quality has become a major issue due to recent conservation efforts to reduce the cost of heating and cooling buildings, increased reliance on mechanical ventilation equipment, and growing awareness that air quality problems can impact the health, comfort, and productivity of building occupants. Since 1974, in the wake of the first oil embargo, the need to reduce building maintenance and operation costs has been a priority of building managers. To reduce these costs, new buildings have been constructed as hermetically sealed structures. Additionally, older buildings have been sealed by the addition of energy-efficient window and door closures. As a result, fresh air ventilation is provided primarily by way of mechanical air-handling equipment.
