Currently, Exterior wall's U-value about building envelope is 0.36W/㎡K(Central Region), but window's one is 2.1W/㎡K according to air gap of glazing, filling gas, coating and type of windows. The door's one is 1.6∼5.5 W/㎡?K depending on material and configuration of door. As such, energy loss per unit of door is considerably larger like windows. The door for the recognition was relatively low because energy loss through the door is relatively small compared to window area. In this paper, thermal performance was analyzed through simulation targeting the door which has thermal break that can improve the insulation performance and doesn't have one. As a results of simulations, case1 was calculated as the average of 1.63w/m2k and case 2 was calculated as the average of 4.14w/m2k. The thermal performance of door depends on the type and condition of insulations. As a results of final simulations, Case1 was calculated as 1.06w/m2k and Case2 was calculated as 1.27w/m2k. As a results of the experiments, thermal performance of case 1 was measured as 1.28w/m2k. Error between experiments and simulations is considered problems encountered when creating the samples. The effect of door frame on the overall thermal performance is slight because it's a small proportion of the door frame.

As the exterior of building has been considered one of the important parts, the use of glass that is suitable to express various appearances gets raised. However, windows possess insulating quality which is 6~7 times lower than walls. Windows are the weakest parts as insulations and also it brings much of energy loss relatively. Lately, highly efficient windows are required as the needs for reduction of energy consumption come to the force. Therefore, Nowadays more people use cooling systems in summer, more the use of Low-E glass is increasing. Because it is good to block Solar Radiant Energy which can cause much of heat loss while cooling system is working. Accordingly, in this study, after making trial product in order to let the Low-E glass applied to windows, we evaluated insulating qualities with U-value measurement equipment.

Generally, the building's windows and ventilation for the purpose of mining and the vista and windows by emotional engineering design area is a growing trend. According to the flow of energy is lost from the building, will be achieved through the walls and roof and windows. Although the basic concept of vacuum window was already initiated in 1893, it has not been developed completely until now because of the lack of manufacturing technology. Recently KIER (Korea Institute of Energy Research) succeeded in developing prototype vacuum window glazing in the lab. By applying the results of this experiment to building energy efficience rating tool, this study compares energy efficiency rates depending on a region.-Jeju, South, Central. And it shows how much does Super window reduce Building energy consumption.

Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. In this paper, energy saving rate will be analyzed and compared considering the window‘s thermal performance in a apartment with Building Energy Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window's thermal performance from 3.3 to 2.0. As a result of this research, reduction rating of heating energy depending on the building law in comparision with standard house will be used in a plan for degree of Building Energy Efficiency Rating System.

Currently the country's foreign energy dependence reaches approximately 97% and the total energy consumption percentage of buildings(commercial and domestic parts) reaches approximately 24%. Building energy saving by enhanced insulation will be very important issue. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. This research used for commercialization and dissemination by basic information.,through a evaluation on airtightness and insulation performance of the window of high efficiency energy equipment which can improve the airtightness and insulation performance

According to flow of energy, the loss occurs through walls, roofs, windows and so on. Among these case, most of the loss that is about 45% occurs through windows. windows's U-value is six times higher than wall's one according to Building code, so the loss through windows accounts for very much rates. Currently, Exterior wall's U-value about building envelope is 0.35~0.58 W/㎡K, but windows's one is 3.3W/㎡K. It means that the loss through windows occupy very much amounts relatively. Therefore, the solution is required to reduce energy loss and increasing displeasure caused by excessive influx of solar energy through windows, to solve the problems Like decoloration on indoor furniture an clothes by harmful ultraviolet rays, air conditioning and increased cost. Therefore, on this paper, Thermal Performance was evaluated through actual test about high insulation Super Window which can improve thermal performace and the Simulation result was compared with actual resul by using Simulation program WINDOW and THERM.
