However, it plays an essential role in the design and maintenance of any facility with live occupants. While 70% of respondents voted within the three central TSV points, within the comfortable range, those who admitted to feeling thermally uncomfortable were usually cold, except in FR mode in Japan. Based on the results, a number of conclusions were drawn. Earlier studies showed that the outdoor thermal comfort range based on physiologically equivalent temperature (PET) index in Malaysia is less than 34°C, thus the data obtained were classified into two state: normal state (within thermal comfort range) and hot state (above thermal comfort range). In this study, thermal comfort in university classrooms in Malaysia and Japan was investigated. Registered in England & Wales No. Comparison of the results between simulations and measurements illustrated a good agreement.
