Green Construction Assessment Model for Improving Sustainable Practices of the Indonesian Government Construction Projects

As an effort to implement the sustainable construction concept in Indonesia, the government, particularly the Ministry of Public Works, took a leader role. Even though the Indonesian construction practitioners have established several notable green movements, such as green buildings and green contractors, the realization to the achievement of proper sustainable construction is far to be seen. Recent studies on the effectiveness of the implementations have shown the need of more holistic approach in delivering the green construction. Based on the holistic approach of green construction concept, the Indonesian government has developed an assessment model for benchmarking the sustainable practices of government construction projects. The assessment model was developed based on three important aspects of green construction: Green Behaviour and Practices; Green Construction Process; and Green Supply Chains. Seven sustainable principles are used for the development of indicators for each aspect of green construction. Two ongoing government projects were used for piloting the assessment model. In general, it was found that the score of the Green Behaviour and Practices aspect, which related to indirect activities, was relatively higher than two other aspects. Some identified low scored indicators in all aspects were used for improvements in sustainable construction practices of the government projects.
