The occupancy for buildings with religious purposes has infrequent periods of use that are near full occupancy to minimal or no occupancy. Thus, energy usage in buildings such as churches has lower overall energy intensity than other commercial buildings. The purpose of this study aims to analyze the use of energy in a church building by using Sefaira extension in SketchUp modeling application and to provide solutions so that the building’s Energy Use Intensity (EUI) value can be within Sefaira standard. This research was conducted by simulating a church building model into Sefaira application, which includes aspects of the assessment, namely building orientation, wind, openings, and material. This study describes the energy efficiency of buildings by changing the materials that are more optimal to respond to the heat received by the building. Changes applied to buildings by optimizing materials such as the application of insulations, ventilation, and solar screen reduce the value of Solar Heat Gain Coefficient (SHGC). This change significantly reduces the energy consumption from 125 kWh/ m 2/yr to 67 kWh/ m 2/yr in the building.
