Now days as building construction and renovation techniques
change to become more energy efficient, the concern over the quality of the air inside the building has become prevelent.
The Indoor Air Quality (IAQ) is a function of the air tightness of the building, the amount of fresh air being brought into
the building and the activities and occupancy of the building.
General ventilation should be checked for amont of fresh air
being delivered .
Local ventilation should be assessed to determine
effects on the general ventilation.
Comfort parameters of temperature and relative
humidity, as well as carbon dioxide and carbon monoxide can be data logged and presented graphically. Carbon dioxide is used
as an indicator of the effectiveness of the ventilation system. Data logging over a 24 hour period or longer often gives a
clear indication of the acceptability of conditions.
The condition of filters and humidification
systems should be inspected.
