Abstract

Thermal comfort can be defined as a state of mind that expresses satisfaction toward the surrounding thermal environment. There are several parameters that can affect a persons’ perception in terms of thermal comfort mark. European Standard ISO 7730 stated that thermal comfort is a combination of four environmental parameters such as air temperature, relative humidity, air velocity, and mean radiant temperature, and plus two personal factors that is clothing (the clothes that occupants wear during the experiment being conducted) and metabolic rate (the activity of occupants during the experiment). This study aims on measurement of thermal comfort at faculty mechanical engineering laboratory. There are two different laboratories that will be conducted in this experiment, one with an air-conditioning system where as another one with no air-conditioning system. The procedure to determine occupants’ responses toward thermal comfort in student laboratory is through observation method associated with a survey. Measurement of actual thermal comfort in student laboratory is accomplished through technical measurement associated with a thermal comfort monitor and correlation of Predicted Thermal Votes (PTVc), Predicted Airflow (PAF), Preferred Airflow (PRAF), Skin Dryness (SD) and etc. The result for experimental laboratory with air conditioning system is 23.4:C to 23.9:C, relative humidity of 58.2% to 60.1%, and air velocity of 0.01 m/s to 0.08 m/s. Whereas fabrication laboratory with no air conditioning system recorded a temperature of 31.3:C to 32.9:C, relative humidity of 63.6% to 68.7%, and air velocity of 0.13 m/s and 0.34 m/s.
