گونه شناسی خانه های سنتی مالایی و واکنش آنها به محیط حرارتی

Rumah Lontiok is one of the types of Malay traditional houses threatened to extinct since it have been abandoned by the local people. Located in Kampar–Riau, Rumah Lontiok has changed from its original form, particularly in using corrugated metal as rooftop material. The study aims to describe the Rumah Lontiok and its environment, and to investigate its thermal performance. Field experiment was carried out in this study. Thermal properties of material were measured by thermocouple and heat flux sensors, while surface temperature was gathered by thermocouple acquisitioned by datalogger. All thermal environment data were gathered for 24 hours. Data of site situation was documented by recording and sketching on the worksheet. The result of the study figured out the situation of Rumah Lontiok and its environments affecting the thermal performance. The in-situ measurement found out that wall has thermal conductivity of 0.21 W/m.K and the floor is 0.19 W/m.K. The study shows that indoor thermal environment did not quite different compared to the outdoor thermal environment. The roof material is hypothesized as major source of heat gain into inside the building. Even though there are many openings, they cannot remove heat gain effectively.
