A study comparatively analyzing the analysis result-related errors based on the information input data items required by energy analysis tools was conducted to verify the validity of the analysis results and construct systematized data through energy analysis tools. In particular, in the process of analyzing energy performance, building materials' property information is an important item used for defining the heat transfer characteristics of a building exterior and evaluating the influence on an indoor load. However, the systematized data still remains to be constructed. Accordingly, in this study, energy performance analysis tools were comparatively analyzed based on the information required by construction materials, and the results were used to construct the baseline data required for systematizing the information input data required by construction materials. A quasi-stationary analysis tool and a dynamic analysis tool were selected as the comparative analysis subjects, and the comparative analysis results were as follows. The results drawn per each level of the information required by construction materials were analyzed as follows: level 1(thickness, heat conductivity), level 2(heat resistance, density, specific heat), level 3(heat absorption, solar absorption, roughness), and level 4(vapor resistance coefficient, visible ray absorption). |
