Improving the performance of construction project using green building principles

Construction projects need to be effectively managed to prevent conflicts and problems between the constructor, users, and the environment, and this requires considering the principles of eco-friendliness, especially for housing projects. This study was, therefore, conducted to set priorities to improve the performance of housing construction project management using the green building principle initiated in 2013 as a benchmark for the Greenship assessment for New Buildings by the Green Building Council of Indonesia. The Importance Performance Analysis was applied to measure the level of user interest and satisfaction on the performance of constructors in constructing housing projects. The results showed technical factors of construction management are dominant in evaluating constructor’s performance. The users expect their houses to be constructed on time according to planned and agreed schedules. Moreover, the factors associated with green building-based performance include reusable and recyclable building materials (mean score of satisfaction level = 3.682 and interest level = 3.882), availability of facilities for people with disabilities (mean score of satisfaction level = 3.420 and interest level = 3.874), eco-friendly materials and construction (mean score of satisfaction level = 3.634 and interest level = 3.840), friendly design and materials for people with disabilities, infants, seniors, and pregnant women (mean score of satisfaction level = 3.704 and interest level = 3.832), and the use of solar energy (mean score of satisfaction level = 3.688 and interest level = 3.825). This, therefore, means the green building is considered important by the users during the construction and implementation processe
