Public Datasets

The ComStock datasets describe the timeseries and annual energy consumption of the U.S. commercial building stock at the end-use level. For more details about data access platforms, structure and contents, visit our external documentation website.

The ComStock GitHub repository contains the source code used to build and execute ComStock models, including upgrade scenarios. In addition, the sampling of building characteristics used for the initial ComStock (V1.0) release is provided. The ComStock model is under active calibration and development, which is publicly visible on this repository.
