Possible close-down of non-sustainable offices is getting closer

Download Report
On January 1st 2023, offices in the Netherlands must have energy efficiency label C or better. With less than a year to go, 43% of the 60 million square meters of office space does not yet meet this requirement. The owners of these offices now risk a fine or even getting closed down. In order to achieve this sustainability target, property owners must act quickly.

Research Consultant


I joined  Colliers as a Research consultant in 2020. My main focus is on the office market and partially the retail market. The research team collaborates with other business lines by providing data and data-analyses. Another main occupation of the team is the publishing of news articles on different topics within the field of real estate. Next to this, I develop dashboards and tools to translate data into market knowledge and visualizations.

Before joining Colliers, I worked for a.s.r. real estate as a researcher.
