The BREEAM certificate (Building Research Establishment Environmental Assessment Method) is a globally leading method for assessing the sustainability performance of buildings and developments. In the Netherlands, this method is applied as BREEAM-NL, managed by the Dutch Green Building Council (DGBC).
What is BREEAM-NL?
Since 2009, BREEAM-NL has been the certification method for a sustainably built environment in the Netherlands. This method enables projects to be assessed for integrated sustainability, taking into account aspects such as energy use, water management, material selection, waste processing, health and well-being, ecology, pollution, transport, management, and innovation. The assessment results in a score ranging from ‘Pass’ to ‘Outstanding’, depending on the number of points achieved in various categories.
Benefits of BREEAM certification
Obtaining a BREEAM certificate offers several advantages:
- Cost savings: Sustainable buildings often have lower operational costs due to more efficient use of energy and water.
- Healthier living environment: Improved indoor air quality and daylight access contribute to the well-being of occupants.
- Increased property value: BREEAM-certified buildings are more attractive to tenants and buyers, potentially resulting in a higher market value.
- Access to subsidies: In some cases, certified buildings may qualify for financial incentives.
- International recognition: BREEAM is globally recognized, enhancing the reputation of the building and its owner.
Insights from the National BREEAM Congress 2025
On March 27, 2025, the National BREEAM Congress took place at the Groot Handelsgebouw in Rotterdam, centered around the theme “Power of Science”. During the congress, various scientists gave mini-lectures on topics relevant to the BREEAM-NL guidelines.
Jolanda Maas on the impact of nature on our health
Senior researcher Jolanda Maas (Vrije Universiteit Amsterdam) addressed the statement: “Images and videos of nature are just as beneficial for health as real nature.” She emphasized that for 99% of our evolutionary history, humans lived in natural, green environments. Studies show a causal link between green surroundings and a reduced risk of depression. A green environment positively affects lifestyle, our immune system, and environmental stressors. People experience less stress and fewer negative emotions in such settings.
Merle de Kreuk on the pros and cons of decentralized water reuse
Professor of Environmental Technology Merle de Kreuk (TU Delft) stated: “Flushing toilets with rainwater is always a more sustainable solution than using drinking water.” She discussed the challenges and opportunities of local water reuse and noted that legislation often doesn’t align with practical implementation. She also explored options for reusing greywater in green buildings.
Andy van den Dobbelsteen on biobased and nature-inclusive construction
Professor of Climate Design & Sustainability Andy van den Dobbelsteen (TU Delft) sees great potential in biobased construction for farmers. He suggested that some farmers could transition to plant-based agriculture for the production of biobased materials, provided that the construction industry guarantees to purchase these materials. He further emphasized that nature-inclusive construction does not have to cause delays and that many low-rise buildings can still be adapted to include nature.
Juliëtte van Duijnhoven on Light: from vision to health
Assistant professor Juliëtte van Duijnhoven (TU Eindhoven) discussed the importance of light for our health and well-being. She explained that the amount and type of light we need depends on the time of day: bluer light in the morning, yellow light during the day, and red light in the evening. This aligns with our biological clock and has measurable effects on health.
Rudy van der Helm on the future of BREEAM-NL
Rudy van der Helm, Manager of Development and Management at DGBC, stated that in the coming years, the focus will be on making data from BREEAM-NL certified projects available to demonstrate compliance with European legislation. A long-term plan for modular updates to the assessment guidelines is also in the works.
The BREEAM certificate is a valuable tool for anyone involved in the construction or renovation of buildings who aims for sustainability. By meeting BREEAM’s rigorous criteria, owners and developers can contribute to a healthier environment while benefiting from economic and social advantages. The insights from the National BREEAM Congress 2025 highlight the importance of scientific grounding in the pursuit of a healthy and sustainable built environment.
