Preparing for a City-Scale Building Energy Upgrade Analysis: A Case Study for New York City

The purpose of this document is to offer an overview of the value of detailed building stock energy-efficiency analysis and to provide a road map of actionable steps New York City (NYC) can take to prepare for such a study. There are a variety of approaches to building stock energy-efficiency analysis. This document focuses on the approach taken by the open-source ResStock (TM) and ComStock (TM) tools, because NYC is interested in learning how it can leverage DOE investment in this area. Although this document was prepared specifically for use by NYC, and the examples highlight application in the NYC context, the steps are written to be generalizable so that other cities interested in building stock analysis can use this as a framework.
