Indoor Air Quality & Air Changes Requirement for Your Home
Indoor air quality (IAQ) has become an important health and safety concern, it relates to the health and comfort of building occupants. Common issues which affect IAQ include Gases (including carbon monoxide, radon, volatile, compounds), particulates, microbial contaminants (mold, bacteria); Improper or inadequately maintained heating and ventilation systems; Increase in the number of building occupants and time spent indoors. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings.
Amount of ventilation: Too little ventilation is bad for us. Too much ventilation, on the other hand, is usually just fine for people but wastes energy in conditioning the extra, unnecessary outside air. Just the right amount of ventilation is the ideal balance between protecting IAQ and health of occupants versus minimizing energy costs .One technique to reduce energy consumption while maintaining adequate air quality is demand controlled ventilation Instead of setting throughput at a fixed air replacement rate.
