Rapid Energy Modeling of Existing Buildings: From Digital Pictures to Comprehensive Energy Footprints

Categorized Under: Energy



ICF International worked with Autodesk to explore rapid energy modeling, a streamlined process to move quickly, and with only the minimal data necessary, from image capture of existing building exteriors through simplified simulation to energy and carbon reduction analysis. Our study included interviews with leading architecture firms and application of Autodesk's workflow on six diverse facilities on three continents. The workflow produced BIM, DOE-2.2, and EnergyPlus models, and delivered results that were close to utility energy use data. ICF found that Rapid Energy Modeling has the potential to be a shortcut to energy use estimation, a stepping stone between quick benchmarking and detailed audits and can help screen high carbon reduction potential buildings, scale up the results across the organization, and stimulate creation of skilled green jobs. It can empower diverse constituencies, from design teams to building owners to tenants, to measure and forecast energy and carbon footprints of existing buildings and invest in energy efficiency measures, within a smaller budget and shorter time frame.
