Can you smell strong, lingering odors in a room? Can you hear or feel a building air conditioning or heating system when it’s on? How do you know if the fire and smoke dampers in a building are in working condition? Is the indoor air quality (IAQ) simply being recirculated or is it property filtered and mixed with an adequate amount of fresh outdoor air?

With the answers to these questions, building occupants, tenants, and owners can decide if the environment they’re in is properly ventilated, if fire or smoke dampers need inspection, and what they can do to take control of their own environments. Building patron absenteeism and productivity are negatively affected by poor or inadequate ventilation, filtration, and thermal health.
