Local governments have access to many datasets that can support planning for building energy efficiency, electrification, decarbonization, cooling, and resilience. When brought together, these datasets can reveal practical insights about local building stock, community needs, and climate risks that help shape better policies, programs, outreach, and investment decisions. The challenge is that these datasets are often spread across different owners, platforms, formats, and levels of accessibility.

This guide brings key information together in one place to help local governments better understand what data exists, what it can be used for, and how to think about combining datasets in practical ways.
