Certification systems – similarities and differences
BREEAM, LEED® and DGNB are the main sustainability certification systems in Europe. The evaluation is based on a variety of criteria that assess the sustainability performance of buildings in a structured manner. The HQE sustainability certificate was launched in France in 2005. As a result, HQE certifications are mainly awarded there. These building certification systems are based on an end-to-end assessment of sustainability performance. To reflect the changing legal framework, the most recent updates focused more strongly on life cycle, resilience and climate neutrality. Economic aspects also play a major role in the DGNB’s evaluation, and an attestation of conformity with the EU Taxonomy can also be obtained at the same time as the certification. The EU Taxonomy generally forms part of all widely used certification systems in Europe.
The WELL Building Standard, which has been awarded since 2014, focuses primarily on the health and well-being of users. Other certification systems dedicated to specific topics have emerged in recent years, such as WiredScore, which assesses a building’s digital connectivity, or net-zero carbon certifications, to name two examples.
