Energy consumption level modeling in urban residential buildings based on Sefaira

Abstract The building sector is a significant global energy consumer, requiring strategic efforts for efficiency improvements. This research focuses on residential homes in satellite cities around Jakarta, where many developer-built houses offer potential for energy-efficient design. Modeling energy consumption helps identify opportunities for implementing energy-saving measures when standards are exceeded. This research takes a case study of three house built by a private developer in the South Tangerang area. The research was conducted using simulation and experimental methods using the Sefaira application from Trimble SketchUp. The location, geometric data, materials, and building form were analyzed to obtain an accurate model of energy consumption levels. All three types of houses fall into the very efficient category based on SNI standards, ranging from 4.17 kWh/m 2 /month to 9.13 kWh/m 2 /month. However, compared to the EUI standard in the Sefaira application based on “The 2030 Challenge”, the EUI values for each building still exceed the expected standard of 25 kWh/m 2 /year.
