ComStock Reference Documentation
This document serves as a guide to and resource for the methodology and assumptions behind ComStock. The Reference Documentation will be updated as major changes to the baseline models are incorporated.

Upgrade Measures
The measure documentation describes the modeling methodology, assumptions, relevant ComStock baseline features, and observations from results.
Geographic Clustering Reference Documentation
These documents provide reference documentation for the clustering methodology developed by ComStock. The clustering algorithm described in this technical report resulted in 88 clusters across the United States. The clusters are used as the geographic basis for the “U.S. Building Stock Segmentation Series” published by DOE’s Building Technologies Office. This series will provide geographically relevant insight into building stock characteristics, energy and emissions performance, and, eventually, common end use technologies. The cluster definitions file maps counties to building stock segmentation clusters.

Building Stock Segmentation
This document discusses the development of a segmentation approach for the U.S. commercial building stock that focuses on identifying similarities that align with common decarbonization strategies. The resulting nine-segment approach primarily uses similarities in heating, ventilating, and air-conditioning systems, service water heating systems, and the presence of cooking equipment to separate buildings into categories.
