Pengintegrasian Embodied Energy (EE) Bahan Bangunan dengan Building Information Modeling (BIM) Pada Gedung Kejaksaan Tinggi Kalimantan Tengah

Construction activities have a significant impact on the environment, mainly through carbon emissions. This research aims to analyze the embodied energy (EE) in buildings as a first step to understanding the energy contribution of the building materials used. Through EE analysis, this research identifies the embodied energy in construction materials and how the selection of eco-friendly materials can reduce carbon emissions. This research uses a quantitative approach to measure and calculate material volume, unit weight, and EE based on data from Revit 3D model and Inventory of Carbon and Energy (ICE). This approach enables precision and standardized analysis, resulting in numerical data that can be objectively analyzed to understand the energy contribution of building materials. The results show that the embodied energy in the structural part of the building is 750,742,975 MJ, accounting for 42.34% of the total building EE, while the non-structural part has an EE of 1,022,321,637 MJ or 57.66% of the total building EE. This shows the importance of material selection to reduce environmental impact
