KINERJA TERMAL BANGUNAN PADA LINGKUNGAN BERKEPADATAN TINGGI DENGAN VARIABEL ATAP, DINDING, VENTILASI DAN PLAFON

High density is a common characteristic of urban settlement in Indonesia, the higher the population in an urban area, the higher the building density. The phenomenon of such settlement will impact to the quality of living especially in fulfilling the standard of thermal comfort requirement and the quality of air movement. Because of air movement problem both indoor and outdoor in high density settlement, high humidity and the intense solar penetration, the heat gain on building is predicted be able to increase both externally and internally. It influences to the thermal comfort mainly inside the building. The research question is how far the thermal behavior of an urban settlement at high density environment influences to the thermal comfort. The research aim is to know thermally appropriate elements of building for each study region based on climatic condition. The used research method is by studying the data collected in the field on some different characteristics of climatic condition to generate typology and building variants. Then they are simulated with a computational program as analyzing software. The research takes place in Malang, Sumenep, and Surabaya as case study. The research result is that commonly the buildings in a high density have a poor thermal behavior. The design of building characterized by using material for roof and wall, single or cross ventilation and ceiling or no ceiling can not provide an adequate thermal comfort. Therefore, based on the simulation method, this research recommends that A2 Model (RL-WL-V1-P0) is suitable for Surabaya (Lowland), A6 (RL-WH-V1-C1) is suitable for Malang (Upland) and A4 Model (RH-WH-V1-P1) is suitable for Sumenep (Coastal area).
