In this study, we analyzed the performance of the envelopes (average heat transmission coefficient and energy transmittance of outer walls and window systems) of E+ Green Homes to meet the heating energy requirements of 15 kWh/㎡·yr under different climate conditions in 7 regional areas in Korea, and derived the correlation between climate and envelope performance to propose its thermal performance with regional climate variabilities reflected. The correlation analysis of the heating energy requirements and envelope performance indicated that the heating energy conditions required for E+ Green Home can be satisfied in the areas with low heating energy requirements by choosing a high heat transmission coefficient for outer walls and glazing systems or a low energy transmittance for glazing systems. Besides, we derived heating degree hour, heating energy requirements, and average heat transmission coefficient of envelopes from average outside temperature of heaters, and as a result, calculated the thermal insulation performance appropriate to the climate characteristics of specific regional area. In the future, to strengthen energy conservation as efficiently as E + Green Homes, it is required to study the correlation between heating energy requirements and thermal insulation performance in areas other than the 7 regional areas, and to consider whether it is possible to apply the correlation of outside air temperature and average heat transmission coefficient to the buildings with different shape and size other than ones applied in the present study. |
