jailcd2020089: Personal Factor Effect to Comfortable Thermal Environment

Abstract

Building has contributed more than 50% of total global emissions. Indoor air conditioning is one of the most energy-consuming aspects of a building. The HVAC system is an attempt to create a thermally comfortable indoor environment. However, thermal comfort is not only influenced by environmental variables but also by personal factors of the user. This study tries to discover people characteristics and the influence of their perception of a comfortable thermal environment, especially in Indonesia. This study was conducted by collecting data from respondents after they felt the adjusted thermal environment. The results showed that the user's physical condition significantly affected his perception of the thermal environment, where poor physical conditions would make them consider the thermal environment to feel hotter and more difficult to feel comfortable compared to people in good physical condition. Another result found is the relationship between the level of sensitivity with thermal sensation and thermal comfort cannot be determined because it is not significant. Another finding is that sleep duration has a significant relationship with thermal sensations, but not with thermal comfort. Further research is needed to further understand how the influence of these variables in shaping human perceptions about the condition of thermal environment.
