How Cities Can Plan the Energy Transition Using Urban Building Energy Models

Urban Building Energy Modeling (UBEM) enables city-scale energy transition planning by integrating simplified physics-based models with urban data and three-dimensional city representations. This webinar presents a UBEM-based workflow demonstrated through a case study of the City of Ithaca and introduces EnergyAtlas.io, an urban digital twin platform available as a web application and Grasshopper plugin. The session shows how urban 3D reconstruction, building archetypes, and reduced-order energy simulation can be combined to evaluate retrofit and electrification strategies at building, campus, and district scales.
