AbstractIn Hong Kong, over 40% of the population reside in public housing estates and the majority of the occupants are elderly and people with disabilities, making them more vulnerable to extreme hot weather. Under near-extreme summer conditions, the poor conditions of thermal comfort is accentuated due to the high air temperature and exposure of solar radiation. The objectives of the present study is to examine the thermal comfort conditions in two common types of buildings in public housing estates in Hong Kong under typical and near-extreme summer conditions. Numerical modelling was used to obtain information about the PMV values and air temperature in the units of the two dwelling types. Results suggested that the level of thermal comfort varies across these two types of buildings. It was found that the more recent building type (Harmony) generally provides better thermal comfort in dwellings. It also exhibits smaller increase in thermal discomfort under near-extreme summer conditions in terms of maximum PMV values recorded. Further work will focus on identifying design parameters that are potentially influential to thermal comfort and the corresponding effect on energy consumption under different meteorological conditions, which will be incorporated into design recommendations in subsequent stage of the study.
