Core Features
The Green Building Registry combines a searchable property database with data verification, standardized building records, and integration services for the US real estate industry.
Building Performance Database: Aggregates records from established third-party programs, including the US Department of Energy's Home Energy Score, ENERGY STAR, LEED for Homes, and the Home Energy Rating System (HERS).
Real Estate Listing Integration: Provides a proprietary API that enables Multiple Listing Services (MLS) and property data platforms to automatically populate listings with verified energy performance and green certification information.
Data Validation and Standardization: Collects information directly from participating program administrators and uses standardized property addresses and data mapping to match certification records with individual buildings.
Energy Performance Documentation: Provides access to available Home Energy Score reports and supports the generation of appraisal-related documentation, helping real estate professionals incorporate verified energy information into property assessments.
Closing Insights
Launched in 2017, the Green Building Registry was developed to address a persistent gap in US real estate transactions: the limited visibility of verified energy performance information. By 2025, the database had surpassed 3.5 million unique properties.
The Green Building Registry serves both private-sector real estate businesses and public-sector housing initiatives. In the private sector, NorthstarMLS partnered with Earth Advantage in 2024 to integrate verified energy ratings and green building certifications into property listings, improving information available to agents, buyers, and appraisers. In the public sector, the City of Minneapolis uses home energy disclosure requirements to improve transparency around residential energy performance, with the Green Building Registry supporting access to such information. These applications demonstrate how GBR can support property transactions while also advancing municipal energy transparency objectives.
GBR's development depends on expanding partnerships with certification programs and property data providers. Although its public search is free, commercial API access requires licensing arrangements.
