Abstract

The purpose of this study is to propose design conditions for small residential buildings to satisfy the building energy efficiency rating of 1++, which is the standard for Zero Energy Building Certification. Unlike non-residential buildings, residential buildings have a high standard of primary energy requirements required by grade, making it difficult to satisfy passive elements without additional energy production. The concept of average U-value by floor area was applied to the conditions of the comprehensive cladding thermal performance of non-residential buildings when it was first announced. The regions were divided into three categories: Central 1 (Chuncheon), Central 2 (Seoul), and Southern (Busan). The results of each region revealed that it was difficult to obtain a target grade of 1++ if only passive and active elements were strengthened and applied without energy production in all three regions. Accordingly, an additional analysis was conducted when solar panels, which are renewable energy, were applied based on a small four-story residential model. If solar panels were installed as much as 82.5Wh/m2a, it was possible to obtain target grades in all three regions. In addition, when a solar panel was installed as much as 55Wh/m2a, it was possible to obtain a target grade if the average U-value by floor area was less than 0.5W/m2K in Seoul, 0.4W/m2K in Chuncheon, and 0.92W/m2K in Busan.
