Abstract

Directorate General of New Renewable Energy and Energy Conservation states that the most signifcant contributor to gas emissions in the Refrigeration and Air Conditioning (RAC) sector in Indonesia is Unitary Air Conditioning (UAC). The percentage of UAC continues to increase because Indonesia has had around 2000 skyscraper constructions since 2015. Regarding future building performance, there are many strategies to design the green building concept, such as how we feel about the building envelope. The building envelope should be prepared to gain energy efciency and can be determined by calculating the Overall Thermal Transfer Value (OTTV). Based on SNI 6389:2011, OTTV has a maximum value of 35 W/sqm. The OTTV itself is equal to the heat load that enters the building for instance, if the OTTV is low then less heat will enter the building. Thus, the use of UAC is also lower. This research will analyze the efectiveness of the building envelope in Building B, Universitas Pembangunan Jaya, which currently uses external shading for the building envelope. However, even with external shading, the use of air conditioning and curtains when the room inside is operating still occurs. It is assumed that the existing building envelope in Building B may not work efectively. Therefore, this research wants to fnd out whether the building envelope in Building B, Universitas Pembangunan Jaya is efective through OTTV analysis and make retroft suggestions to improve building performance.
