BIM Utilization in Improving Energy Efficiency Performance on Architectural Design Process: Challenges and Opportunities

Abstract

BIM utilization for energy simulation efficiency is increasing in Indonesia. BIM itself is one of the methods for carrying out building energy efficiency because it has dimensional features that can create collaborative work processes efficiently. This paper aims to describe BIM and building energy workflows in the design process and see the trend of BIM utilization in Indonesia, especially in the architectural design process. The methodology of this paper is a survey by online questionnaire for BIM stakeholders to make an overview of to what extent construction industry stakeholders have utilized BIM in Indonesia, especially in the design phase especially in building energy simulation. The BIM workflow that is integrated into building energy calculations can make the energy-oriented building design process. In addition, it can provide exciting and informative diagrams for the calculation of embodied energy will make it easier to understand the building energy by building construction stakeholders. In the final analysis of this paper, which is the hypothesis model of problem and solution of BIM utilization in Indonesia, there are 4 main problems and solutions according to the analysis of the questionnaire result: Flexibility and Collaboration, Technical Skill Problem and Training, BIM Management Data, and Low-Cost BIM. BIM utilization in Indonesia is still limited, especially in its use to analyze and mitigate building energy.
