To support design of building energy codes and achievement of building energy targets across sectors, the government of Indonesia assessed energy savings of various energy efficiency measures in Jakarta’s building sector. As presented below, sensitivity analysis found that easily implementable measures could allow for energy savings of 30%–40% in new buildings in Jakarta. Implementing these measures through building codes may support Indonesia in meeting a high level target of 30% average energy savings in new buildings.
