Implementation of Passive and Active Design Strategies for Energy Efficient Office Building

Abstract

According to EECCHI 2012, the building sector absorbs 40% of total energy worldwide. Even in Indonesia, the building sector is responsible for 50% of total energy expense and more than 70% of total electricity. These issues make the energy efficiency are significantly important to reduce the energy consumption and cost, also to reduce carbon emission especially in a building sector. Office building become a potential electricity consumer in commercial sector. Office building also become one type of building which has 25% of energy efficiency potential, greater than other types of buildings. Based on SNI data in 2000, the average energy consumption of rental offices in Indonesia are 250 kWh/m 2 per year, but in 2017 UN International Forum of Sustainable Development, the building energy consumption was targeted to 90 kWh/m 2 per year by 2030. VOZA Office Tower Surabaya will become a case study of office building type to be analyzed. The energy consumption of the existing building will be simulated with EDGE Software. The result will be the baseline to conduce the passive and active design strategies recommendation which will reduce the building energy use, so the building will reach maximum energy efficiency.
