The use function is a core concept in Dutch building regulations: parts of one or more structures with the same use designation that together form a use unit. The term comes from the Dutch building decree (Bouwbesluit, since 2024 absorbed into the Besluit bouwwerken leefomgeving).
Features
Each use function is subject to different performance requirements, for example for fire safety, daylight, ventilation and floor area. The regulations distinguish, among others, the following categories:
- Residential function (dwellings, residential buildings)
- Assembly function (theatres, childcare, churches)
- Cell function (prisons, police cells)
- Healthcare function (hospitals, nursing homes)
- Industrial function (factories, workshops)
- Office function
- Accommodation function (hotels, guesthouses)
- Education function (schools)
- Sports function (sports halls)
- Retail function
- Other use function and structure that is not a building
Application
The use function determines which set of requirements applies to a (part of a) structure:
- A permit application is assessed per function.
- A building may contain several use functions (for example retail on the ground floor, residential above).
- Each function has its own limit values for safety and health.
