Indoor Air Quality is always a big concern & challenge in all buildings having high occupancy levels. Maintaining Indoor Air Quality is the most critical part of HVAC due to high occupant's levels. Poor indoor air quality results to adverse effect on the health of the occupants. Poor indoor air quality results to adverse effect on the health of the occupants inside the building, as most of the time spent inside the building means we all need to breathe quality of inside air only. Other then occupational health problems poor IAQ also results to fatigue and loss of productivity.
Poor IAQ results to various health problems as reported by occupants of the building, which is often calledSick Building Syndrome (SBS). Sick Building Syndrome (SBS) is used to describe cases where building occupants experience adverse health effects e.g. dizziness, fatigue, high head, headache, nausea, dryness and irritation of the eyes, nose, throat and skin, shortness of breath, hypersensitivity, allergies, coughing etc.
High occupancy in any building leads to high ventilation rates .Designing the HVAC system as per recommended ASHRAE 62 standards requires designing the HVAC with either high amount of fresh air as determined & defined by the number of occupants inside the building. This adds up additional load on the HVAC system requiring extra tonnage resulting to high capital cost. This also puts additional recurring power cost burden.
