| Research Abstract |
Since great concern is being paid to global warming and resource/energy exhaustion in these days, passive buildings aiming at energy saving and reduction in environmental load are highly required. The objectives of this research are; to measure indoor and outdoor thermal environment and analyze the indoor environment in order to investigate the influences of the local climate conditions and the effect of the introduced passive methods, and to make an integrated evaluation on thermal aspect, regarding an experimental house built in Surabaya, Indonesia and a colonial style guest house in Penang, Malaysia. Furthermore, by making use of these results, strategy for improving passive methods is searched, and a new technique which makes use of the local climates and a new environmentally friendly house are proposed.
The measured results on the experimental house in Surabaya and the colonial style guest house in Penang were analyzed. That is, the indoor temperature and humidity, radiation heat transfer including solar radiation and the air flow in and around the house were analyzed. By comparing the calculated and measured results, the validity of the simulation model was confirmed. By making use of this simulation program, the influences of the incident and reflected solar radiations on the indoor thermal environment, the effect of the shading on the shading and ventilation efficiencies, and the influence of the ambient environmental conditions on indoor thermal environment were examined. The cooling effect by the circulation of the cooled floor water was evaluated considering the open or close of the openings, and the optimum control of the openings was determined.
Along with these studies, the indoor thermal environment of the existing detached and apartment residential houses in Surabaya were measured and analyzed. The usage of the air-conditioners was surveyed.
