| Abstract |
We cannot imagine any more the environment and energy problems are separated from our lives. The various attempts to solve these problems are made all over the world. In this study it was performed to analyze a different energy needs for heating and cooling depending on the earth-sheltering method and soil thickness by using TRNSYS 16 as the first step to establish the design guidelines for earth-sheltered architecture, one of the eco-friendly and low energy consuming builing types. From the result after performing a simulation, it is the most lowest energy needs in case of all of walls and roof being earth-sheltered. But considering of the energy needs reduction rate, the effect of earth-sheltering the exterior vertical wall is more efficient for energy needs reduction than the one of earth-sheltering a roof. Afterwards we will conduct a further study for boundary condition at earth-sheltered surface and the simulation analysis about the sensitivity variables. The final goal of this study is preparing the design guidelines for earth-sheltered architecture, so we will contribute to building energy saving. |
