Auto-calibrated urban building energy models as continuous planning tools for greenhouse gas emissions management
… rapid estimation of unknown building properties (auto-calibration). Finally, a continuous energy performance tracking framework is presented to enable university campuses to manage their building related greenhouse gas emissions over time (continuous planning). As a proof of concept, the complete …
