Currently, strengthen of the buildings energy efficiency of is need according to has become necessary growing instability of energy supply, and interest of the climate change agreements and global environment. As a result, the government is preparing measures to save energy in buildings to deal with changes in the global environment and high oil prices. In architecture, insulation is the basis for building energy saving because heating load and energy consumption as the most basic method for reducing energy consumption of buildings directly related to cooling load. The insulation performance of the building envelope is determined by the thermal performance, such as the density and thermal conductivity of insulation. Thus, the performance of insulation materials is an important issue directly related to the energy saving of building. For this reason, the construction market is increasing the demand of insulation for economic and better than before. The purpose of this study is to compare the types and characteristics of insulation materials by principle and to analyze the annual energy consumption and economic feasibility by insulation types.
