Measuring BIM’s technology readiness in designing healthy-green buildings in Indonesia

The need for buildings to support the population’s economy continues to grow, especially in big cities. On the other hand, the construction sector consumes 36% of the world’s energy and accounts for 39% of all greenhouse gas emissions, such as CO2, in the world generated using fossil fuel electrical energy in buildings. In addition, the duration of activity of building occupants in the room can also affect the health of its occupants in the long term. This phenomenon is called sick building syndrome. Greenship, EDGE, and WELL standards which focus on environmental sustainability and the health of building occupants were introduced to solve these problems. However, to achieve this goal, the complexity of building design may increase. Building Information Modeling (BIM) can help unravel the complexities of design based on each of these three standards to their assessment. In the future, it is hoped that there will be more building professionals that prioritize the construction of buildings with Greenship, EDGE, and WELL standards in Indonesia. Therefore, this study focuses on the readiness of utilizing BIM in designing healthy-green buildings. This study uses a quantitative approach using questionnaire. Questionnaires were distributed to respondents with backgrounds as architects, contractors, or green building consultants. This study shows that the respondents are quite sure that BIM can facilitate the flow of information and communication of team members in the building design to the construction phase. However, when measuring the readiness of BIM technology to design, build, to simulate the operation of buildings that have high complexity such as healthy green building, the general consensus of the respondents is neutral with a slight tendency towards optimism on the BIM technology readiness. Respondents feel confident that BIM is best equipped to achieve Greenship standard design requirements. As for the other two standards, i.e., EDGE and WELL the respondents tend to be neutral.
