Regular indoor air quality testing can benefit the occupants in several ways. Firstly, it can improve the health and well-being of the occupants. Poor indoor air quality can cause respiratory problems, allergies, and other health issues. The testing can help identify the source of the problem and provide solutions to improve the air quality. Secondly, it can increase the productivity of the occupants. Clean air can improve concentration, reduce fatigue, and boost productivity. Thirdly, it can reduce energy costs. The testing can identify areas where the HVAC system is not working efficiently, resulting in energy wastage. By addressing these issues, the building can reduce energy consumption and save on costs.
