Analyzing Indoor Environment of Minahasa Traditional House Using CFD

Abstract Raised floor can be found in many traditional buildings throughout Indonesia, however this element currently disappears from Indonesia modern architecture. One of possible reason is limited study conducted on raised floor house, therefore the benefits of raised floor element; especially its application in tropical climatic is never exposed. Minahasa Traditional House is a traditional raised floor house that still exists today. This paper will investigate thermal comfort conditions particularly wind velocity inside of Minahasa Traditional House using Computational Fluid Dynamic (CFD) analysis. Simulation on several variations of openings and stilts height is conducted to measure its effectiveness in creating thermal comfort. The result of the study will become a reference for modern architect to design modern house that incorporate design features from vernacular architecture.
