Impact of elevated outdoor MRT station towards passenger thermal comfort: A case study in Jakarta MRT

Human comfort is affected by both physical and psychological factors. Human requires an optimum environmental condition to work effectively and effi ciently. Bridger (2003) in his book mentioned several things that cause human comfort, for instance: temperature, light emitting, humidity, air circulation, odor, dust, sound and lighting. The microclimatic parameters around the MRT depend on its layout, material, size, air/wind fl ow through the surrounding buildings and quality of the air carried by a moving train. The British standard BS EN ISO 7730:2005 defi nes heat comfort as conditions and situations of the human mind that express his/her satisfaction towards the heat level of the surrounding environment. Heat comfort describes psychological conditions that indicate feeling cold or hot. Heat comfort is subjective and as the result, it is diffi cult to defi ne what “comfortable” is. According to the standard ASHRAE 55-2004, thermal comfort is the level of human perception related in expressing their satisfaction towards the thermal environment and this perception depends upon subjective views. Ponni and Baskar (2015) explained that thermal performance of a building is a description of the process of modeling energy transfer between a building and its environment. The Health and Safety Executive noted that the most suitable indicator of heat comfort is number of individuals Scientifi c Review – Engineering and Environmental Sciences (2020), 29 (1), 93–107 Sci.
