Overview of changes to the Assessment Method and EPB in the period 2024 - 2025
Overview of changes at St. NMD regarding the Assessment Method and the requirements concerning the Environmental Performance of Buildings (EPB)
Stichting NMD is preparing for several important changes to the Assessment Method and milestones of the NMD. Some of these changes are in conjunction with actions by the Ministry of the Interior and Kingdom Relations which is working on the amendment proposal of the Building Works Decree (Bbl) and the Environment and Planning Act.
Because the market needs time to get used to and adapt to the changes, there is a transition period between the publication of changes and the effective date.
A number of changes are involved, so we have created an overview page. Here you will find all the information you need about the changes occurring in 2024 and 2025 with respect to the Assessment Method and the requirements concerning the Environmental Performance of Buildings (EPB).

Please note that the information on this page is regularly supplemented and/or updated.
