Abstract

ASHRAE has recentily named a TC4.7 subcommittee on Multi-Scale Energy Modeling and there have been many technical developments focused on urban-scale energy modeling with the goal of creating building energy models for all buildings in a city to facilitate simulation-informed energy optimization for the built environment. These efforts often rely on non-scalable, local sources of information (e.g. county's tax assessor's database) to create more accurate models of those buildings. In partnership with the local utility, a year's worth of real-world 15-minute electrical use data from 178,37 buildings has been assessed. This smart meter data is statistically analysed and compared to corresponding simulation data for 97 different building prototypes in order to better assess simulation accuracy for various utility-defined use cases. To our knowledge, this is the first time real world an simulated building energy use data have been compared at this scale.
