Issues of air quality in buildings (schools, offices, residences, etc.) may be difficult to diagnose. Sick building syndrome or building-related illness often has no obvious origins. If air supply is insufficient then air contaminants may accumulate at sub-threshold levels, not noticeable but effecting the comfort of occupants or their perceptions about the quality of the indoor air. Where ventilation is inadequate to meet demand, individuals may report “stale” air, odors, or they may express discomfort such as headaches, nausea, a lethargic feeling and/or malaise.
IAQ screening procedures can identify potentially problematic areas within the indoor environment. Typically carbon dioxide monitoring is performed as an indicator of whether the mechanical ventilation system is performing adequately. Controlling the buildup of low level indoor air contaminants is often key to resolving many IAQ issues along with ensuring thermal comfort is satisfied.
A systematic IAQ investigation may be necessary. Dust on furnishings, stains on ceilings, discoloration of wall paint, pests, etc. sometimes lead to these questions. Each situation requires a different solution and approach. A ventilation review may be warranted. Testing for specific air contaminants in the building such as formaldehyde, volatile organic compounds (VOCs), styrene…. or for mold spores may be the next step. OSHTECH has test equipment, a fully accredited laboratory and expertise to address these matters. Contact us if you need assistance in dealing with these issues.
