Abstract
The engineers and architects today confront the question of how to build energy-efficient buildings. The price of fossil fuels more expensive and limited source is the cause of this issue. The study aims to determine the usage of an indirect evaporative cooling strategy to cool the building for thermal comfort in a tropical humid climate. Comfort ventilation is one of passive cooling strategies that always used to make the thermal comfort, but still there are some schemes that can be used depends not only on the strategy. Hot and humid conditions are a major problem in achieving thermal comfort for buildings and it is necessary to require cooling strategy. In that respect are several strategies for passive cooling but the application of indirect evaporative cooling to buildings in humid tropical climates is still less attention seriously. For this purpose, it is necessary to apply a strategy of indirect evaporative cooling to a building model. A model house has been constructed with plywood for the walls and floors, and roofs of corrugated zinc. A system distribution of spraying water on the roof surface has been utilized and laid on top of the roof. Some measurements have been carried out and from there it can be concluded that this prospective strategy used in buildings, especially to lower the temperature of the surface of the roof. Water spraying can reduce the surface zinc temperature by an average of 4°C. Nevertheless, making less roof surface temperature cannot be secured to reduce directly the average indoor air temperature in the edifice. In this case, there are some other requirements that are responsible for indoor air temperature in the building; especially with large openings. To reach a bigger advantage of making less roof surface temperature required the water spraying in the long duration, approximately 10-15 minutes, which carried out continuously; especially when the external temperature is very high.
