The BREEAM API allows you to explore and integrate BREEAM rating data on thousands of certified building assessments across 50 countries directly with your own tools, websites or software.

We are opening our RESTful API web service to allow you to search and access up-to-date BREEAM GreenBook listing information in a machine-readable format and explore BREEAM ratings data from around the globe.

The data available through the BREEAM API allows user to access information on certified assessments.

Please note: the data available through the API only includes certified assessments of projects or assets under the BREEAM, HQM and CEEQUAL schemes, and does not contain data on certified assessments of projects against the Code for Sustainable Homes or BREEAM Ecohomes schemes. Furthermore, this service only contains data on assessments which were certified against the BREEAM 2008 scheme onwards. Projects or assets with certified assessments to schemes released prior to this are not included.
