Currently, the GRESB API is available for submitting data to the GRESB Real Estate Assessment only. Data submitted through the API goes to the GRESB Asset Portal where a user can aggregate their asset-level data to the portfolio-level assessment. Quantitative data goes to the Performance Component of the Real Estate Assessment and covers the reporting requirements captured in the Real Estate Asset Spreadsheet. Qualitative data can be submitted directly to the Management & Development Component of the Real Estate Assessment via the GRESB API.
GRESB API Partners
GRESB Assessment Partners at the Global and Premier levels are eligible to connect to the GRESB Portal via an API. Partners who have successfully established this API capability are designated as GRESB API Partners in our Partner Directory. These Partners are able to use the “GRESB API Partner” logo, as well as promote themselves as “GRESB API Partners.”
