VENTILATION COMFORT CHART FOR SEMI-OUTDOOR SPACES IN THE TROPICS

摘要

In tropical regions, semi-outdoor spaces are very common in commercial buildings or residential buildings. In this study, we conducted questionnaire survey in several places which could be regarded as semi-outdoor spaces. The questionnaire survey covered both the objective measurements and the subjective evaluations, which were conducted simultaneously. Based on the data from the field survey, simple relationships between the air temperature and thermal comfort votes (TCV) at each air velocity and RH bin were established using the linear regression technique. A ventilation comfort chart was developed to illustrate the interdependent relationship amongst the three environmental parameters (air temperature, RH and air velocity) in affecting thermal comfort of semi-outdoor spaces in the tropics. The ventilation comfort chart can provide useful reference to designer in terms of achieving thermal comfort in semi-outdoor spaces.
