농촌 마을회관 제로에너지 건축물 구축을 위한 에너지 성능 분석 연구 농촌 - 충남 태안군 정죽4리 마을회관을 중심으로 -

Abstract

In this study, we survey the 2 buildings at the Central 1 and 8 buildings at the Central 2, which are divided by each climate region in the rural regions. Major heat loss factors are 47% loss of the outer shell including outer wall, roof , and bottom, 30% loss through window, and 23% loss through crevice wind. We analyze the energy simulation of ECO2 program to construct a zero energy building regarding village hall located in Jung Juk 4-le at Centeral 2. We simulate the primary energy requirement regarding village hall and the simulated results show the 265.3 kWh/m²･a and it may estimate `2` energy efficiency grade. The energy requirement regarding village hall is the 183.2 kWh/m²･a when the passive technology are applied in village hall. We research total amount of energy requirement in village hall when the passive and active technologies such as solar cell with 3kW and solar thermal with 20m², geothermal power with 17.5kW. The simulated results show the improved energy efficiency certification grade with 1+++ due to the reduced primary energy requirement with 73% when passive technology including 3kW of solar panel is applied and the energy independence rate is 54%, which is estimated to be 4th grade of zero energy buildings. The order of energy consumption are solar panel, solar thermal, and geothermal power under applied passive technology in the building. In order to expand the zero energy building, it is necessary to introduce the zero energy evaluation system in the rural region.
