The BREEAM GreenBook API

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.
