Passive House performance evaluation and key management factor analysis in the Sino-German Ecopark: A study through fieldwork and interdisciplinary joint research

Abstract

In terms of eco-friendliness, China is far behind advanced western countries. Recently, however, several places in China have been collaborating with the German Passive House Institute to construct eco-friendly buildings on a large scale. This study intends to analyze the passive house construction technology being implemented in the eco-friendly buildings that have been completed or are under construction at the Sino-German Ecopark in Qingdao, among several other complexes, based on fieldwork and interdisciplinary joint research. This study compares the importance of key factors through analytic hierarchy process (AHP) analysis. This study aims to extract and present factors of high difficulty noted in the successful construction of passive houses by examining the fieldwork of three case projects at the Sino-German Ecopark. These factors were divided into three categories: technical factors, policy factors, and managerial factors. Through AHP analysis, it was determined that the policy factors were of higher importance than technical and managerial factors. Barrier-free facilities were the most important factor among all the policy factors, and the window system was the most important among the technical factors. In the case of management factors, project management ability proved to be the most important factor. The findings of this study are expected to serve as a guideline that should be considered in the future Passive House design and construction process.
