Indoor air quality (IAQ) has a direct impact on the health, comfort, productivity, and overall job satisfaction of building occupants. Poor IAQ can contribute to a wide range of symptoms, including:

• Dryness and irritation of the eyes, nose, throat, and skin

• Headaches

• Fatigue

• Shortness of breath

• Hypersensitivity and allergic reactions

• Sinus congestion

• Coughing and sneezing

• Dizziness

• Nausea

Managing indoor air contaminants—whether generated inside the building or introduced from outdoor sources—is essential to maintaining a healthy environment. Common contaminants include:

• Carbon dioxide from human respiration and indoor activities

• Carbon monoxide produced by combustion appliances and vehicle exhaust

• Volatile Organic Compounds (VOCs) off-gassed from new furniture, carpets, wallboard, paints, and adhesives, including formaldehyde

• Dust and fibres originating from carpets, insulation, drywall, human skin cells, and outdoor infiltration

• Mould associated with moisture intrusion, water-damaged building materials, and even certain houseplants

In addition to contaminant monitoring, a comprehensive IAQ assessment may include measurement of:

• Temperature

• Relative humidity

• Noise levels

• Lighting quality

• Ozone

Our team provides IAQ evaluations, sampling, and recommendations to help clients address deficiencies and improve occupant well-being. We also support organizations seeking certification under WELL Building Standard and LEED (Leadership in Energy and Environmental Design) by conducting the required air quality testing, documentation, and ongoing monitoring needed to achieve and maintain compliance.
