| Abstract |
The technology of the reduction on heating energy used by passive solar system has been developing with various types. Insulation Materials had been used in living building as one of the technology of the reduction on heating energy. A lot of researches were developed around North Europe where has the longer heating time and the lower outdoor temperature. Meanwhile, in order to advance the system efficiency, active researches has been proceeding in the new material developments. At present, the new developed transparent insulation materials has the advantage that maximized Mass-wall system's energy reduced efficiency. Therefore, Optimum Design Configuration was turned out by the experiment and the simulation analysis for various of each country's climate and was succeeded in the spread. The aim of this study is to propose the best fitted plan on transparent insulation wall and common material wall suit national climate by the efficiency experiments and simulation sensitivity analysis on heating season and cooling season energy. The process of this study is as follows: 1) By the Mock-up model, the experiments about the heating energy reduced efficiency at the heating season and the prevention from overheating at the cooling season for transparent insulation materials wall and common materials wall were conducted. 2) derived a Simulation model after Calibration using an ESP-r simulation program. 3) After selecting as a variation types of TI-Wall and Mass-Wall, thickness, surface absorbtion and size of air gap with Simulation model, performed Sensitivity Analysis 4) As a result of Sensitivity Analysis, derived Optimum Design Configuration in accordance with elements of TI-Wall and Mass-Wall. In conclusion, in a national climate Concrete is better than cement in TI- Wall system and Mass-Wall system. TI-Wall system is that thickness 250mm, surface absorbtion 95%, air gap 50mm, Mass-Wall is that thickness 300mm. surface absorbtion 95%, air gap 50mm. |
