PHPP를 활용한 일반 목조주택과 목조 패시브하우스의 난방에너지 성능 비교 분석

Abstract

In recent times, it has been an increased demand of wood frame house in Korea due to their environmental performance and economic feasibility. Most of the passive houses in Europe have been made of wood and showed superior energy performance. To improve thermal performance of Korean wood frame house in the level of passive houses, analysis of thermal properties such as heat gain, heat loss, and annual heat demand was conducted between Korean wood frame house and wooden passive house using PHPP (Passive House Planning Package) 2007 program. PHPP is excel-based program to calculate anuual heat demand based on DIN EN 832 and EN regulations of European Union. The simulation results showed that annual heat demand of Korean wood frame house was 78 kWh/m2a and most of the heat loss was transmission heat loss of windows because of their low thermal resistance. Detailed and advanced criteria for Korean wood frame house are needed in the future to save building energy and maintain comfortable indoor environment.
