Abstract
Thermal comfort influenced by thermal sensation is an important building performance indicator In the context of this work the applicability of adaptive comfort model ACM to simulate the thermal comfort level in a naturally ventilated hostel building at Obafemi Awolowo University Ile-Ife Nigeria was investigated The applicability of ACM was investigated by determined the neutral and comfort temperature in addition to comfort range temperature of the occupants using the environmental data derived from field measurements and information from questionnaire survey A total of 288 responses participated in the three months short-term thermal comfort field study The results obtained were compared with the recommendations of ASHRAE Standard 55 ISO 7730 Standard and results of previous field studies located in the warm-humid tropics The predicted neutral temperature was found to be 26 8 o C The acceptable ranges of comfort temperature around thermal neutrality were 24 3-29 3 o C and 23 3-30 3 o C for 90 and 80 acceptability These values closely matched the recommended range of ASHRAE Standard 55 and ISO 7730 standard The results of this study indicated that the use of ACM seems to be promising regarding the prediction of indoor climatic conditions under steady-state non-uniform environments The study concluded that the adaptive algorithms are more reliable to evaluate the thermal comfort in naturally ventilated buildings
