Human being appreciate the relief from discomfort afforded by a modern air conditioning system. In the present day, many houses, offices and commercial buildings or facilities would not be comfortable to stay in without control of the indoor air environment. Air conditioning refers to the control of air temperature, moisture content, cleanliness, air quality and air circulation as required by an occupant, a process or a product in the space. The study was divided into three major parts which consists of cooling load calculation method, Indoor Air Quality (IAQ) and flow simulation. The first part involved the comparison of various methods of cooling load calculation for equatorial climates (hot and humid), cooling load calculation suitable for peak load calculation and cooling load energy analysis, implication of under size air conditioning system and cooling load per square meter for specific building (Building functionality).The results on the first part of the study shows that for building with high ceiling and high volume of occupants, it is recommended that the peak cooling loads per square meter shall be between 0.121kW/m2 and 0.159kW/m2.As for offices, it is recommended that the peak cooling load for high efficient buildings are from 0.058kW/m2 to 0.106kW/m2. The second part of the research is on Indoor Air Quality (IAQ) sampling which was conducted during UNIMAS Convocation in year 2012. The sampling of IAQ was successfully completed with collaborations Department of Occupational Safety and Health (DOSH) Ministry Of Human Resources, Malaysia.
