Understanding Multifamily Energy Use in the Greater Gulf Coastal Plains: Building Stock Segmentation for Retrofit Planning

Summary

This report addresses the challenge of effectively planning energy retrofits for large multifamily buildings in the Greater Gulf Coastal Plains due to a lack of detailed understanding of their energy use patterns and building stock characteristics. The National Renewable Energy Laboratory (NREL) conducted a segmentation analysis of the large multifamily housing stock across 367 counties, providing data-driven insights into energy consumption by end-use and identifying top segments for targeted energy efficiency and decarbonization retrofits. Published in June 2025, this report aims to guide local governments, utilities, and building owners in developing actionable next steps for improving energy performance in these buildings.
