BREEEAM-NL, developed by the Building Research Establishment (BRE), stands for BRE Environmental Assessment Model. BREEAM is an instrument used to analyse and improve the sustainable building design and operation. The original goal was to entice the marketplayers into sustainable construction but it is currently used as means of assessing building's design and performance.

The Dutch Green Building Council (DGBC) is an independent, non-profit organisation that strives for the continuing sustainability in the Netherlands. DGBC has adapted the English version and turned it into BREEAM-NL.

The DGBC develops and maintains three labels.

With REINÆRDT's Green doorsets you receive a higher score average with BREEAM's scoring system resulting in a positive evaluation of the buildings' sustainability performance.
