Extraction and analysis of technical management factors for passive houses in Korea

Abstract

Construction projects are diverse, ranging from industrial infrastructure to residential facilities, and all of these consume energy during operation and maintenance. From this perspective, passive houses can serve as a green housing model for energy-savings. However, Koreans have not actively adopted passive houses in domestic construction compared to other countries, since the energy cost savings are low compared to construction costs. This study extracts the technical management factors in domestic passive house building through a review of the related literature and a focus group interview (FGI) of relevant experts. Additionally, the relative importance of the 6 high-level management factors and 22 low-level factors was analyzed using the analytic hierarchy process (AHP). The results show that the most important items relate to the performance of the construction materials and the techniques used in construction. The results should help further the development of a passive house model and technical management tailored for the Korean market.
