This ensures that there is a constant change of air , to maintain good indoor air quality ( IAQ ) within the building . The IAQ is one of KEN ’ s concerns as it affects the health factor of the building occupants .
Hence , an IAQ test with reference to the Malaysia Industry Code of Practice on Indoor Air Quality 2010 was carried out to identify the potential sources of indoor air contaminants and to assess the exposure of the indoor occupants to any health risks . Air temperature , relative humidity , air movement and the adequacy of mechanical ventilation are monitored . In general , the overall IAQ condition within monitored locations can be considered “ Satisfactory ”.
Apart from that , according to the Thermal Comfort Tool for ASHRAE-55 as shown in Figure 12 , the indoor temperature is 23 º C and the design relative humidity is 60 %. This shows that Menara KEN TTDI complies with the standard . To achieve the desired thermal comfort level , the Outdoor Air Handling Unit delivers pre-cooled fresh air into the respective spaces of the building minus the heat load and the desired air speed through the Fan Coil Units .
