【 摘 要 】

This study aims to determine the effect of materials used in building envelopes on energy use in office buildings. To obtain energy use analysis data, ASHRAE 90.1 - 2013 based parameters are used in the Sefaira Building Simulation application. The building analyzed will be simulated, using variables such as sunlight conduction with roofs, walls, building window ratios, gap ratios in buildings, and use of electrical equipment per square meter. Based on the analysis carried out, the use of building energy by using standard material specifications from the application reaches 180 kWh / m2 / yr from what is supposed to be 79 kWh / m2 / yr. After being analyzed, a specification change is given to the liquid application so that the results of the analysis are 89 kWh / m2 / yr. So that the energy that can be reduced reaches 91 kWh / m2 / yr. This proves that the selection of building material specifications can affect energy use in rental office buildings.
