CityRetroFit: Development of a District-Scale Digital Twin

Abstract: CityRetroFit integrates publicly available datasets with building archetypes to create urban building energy models (UBEMs). The platform integrates geospatial data, occupancy schedules, envelope constructions, and HVAC system characterizations for both baseline and potential retrofit scenarios and supports retrofit prioritization at scale. This paper summarizes the development of this workflow in a mandatory building energy disclosure context () and its extension to jurisdictions without such disclosure (). A case study of is presented to demonstrate the workflow and its validation with aggregate energy data. The results show CityRetrofit’s adaptability across jurisdictions to inform urban decarbonization policy.
