Analysis of thermal performance of wood and exposed stone-walled buildings in mountainous areas with building envelop variations

Abstract

A building's ability in creating thermal convenience will produce energy saving. Such an ability of a building is known as building thermal performance. Building thermal performance is highly influenced by the building envelop and environment temperature. This research aims at analyzing the thermal performance of two woodand exposed stone-walled buildings in mountainous areas. The measurement uses a scaled prototype of 0.60 m x 0.60 m x 0.60 meter size. Determination of building materials in accordance with local material conditions results from previous studies. The roof uses four material variations, namely roof tiles, zinc, asbestos and thatch. The floor uses three material variations, namely earth, concrete rebate and ceramic. There are a total of 32 building envelope variations. The measurement is performed for 24 hours for each variation model. The analysis uses a graphic and it will shows the difference between woodand exposed stone-walled buildings. The research results generally show that air temperature inside wood building is higher than in exposed stone building. The highest indoor air temperature difference between the wood building and the exposed stone building is 0.37o C. Finally, the building variation with the highest thermal performance is the one with zinc roof and earth floor.
