Natural Ventilation and Temperature Conditions in Some High-rise Building Flats in Bandung and Jakarta in Perspective of Adaptive Thermal Comfort

The effect of increasing RUSUNAMI high-rise and low cost building flats construction has brought about some problems. One of them is the use of air conditioning in many building flats. It shows that the objective of the RUSUNAMI is not fulfilled because it needs additional operational cost for air conditioning. Two RUSUNAMIs in Bandung and three RUSUNAMIs in Jakarta were selected and measured related to ventilation and indoor air temperature. This paper examines the performance of natural ventilation and indoor air temperature and their ability in thermal comfort with the adaptive approach. In general, all RUSUNAMI is not effective in utilizing the wind because it is designed for air conditioning. On this occasion, it is discussed the opportunities of natural ventilation associated with utilization approach of adaptive thermal comfort.
