What is an equivalence assessment?
Not every building or installation complies with the standard requirements of the Besluit bouwwerken leefomgeving (Bbl). Sometimes an alternative solution offers the same or even a higher level of safety. An equivalence assessment allows you to demonstrate that your solution meets the performance requirements of the legislation, even if it deviates from the prescribed design.
Normec independently assesses whether the chosen solution is equivalent to the legal requirements. This provides clarity for clients, regulatory authorities, and insurers.
When is an equivalence assessment required?
An equivalence assessment is conducted when a building, installation, or design deviates from standard regulations but must still demonstrate the same level of safety.
Common situations include:
- Deviations from the Besluit bouwwerken leefomgeving (Bbl)
- Alternative fire safety solutions
- Non-standard designs for technical systems
- In-building or underground boiler rooms
- Large combustion plants or special building functions
In these situations, an equivalence assessment helps to objectively substantiate the chosen solution.
How does Normec conduct this assessment?
Our specialists assess both the design and the technical and safety-related justification for the chosen solution.
The assessment typically consists of the following steps:
- Assessment of the design and underlying principles
- Verification against the performance requirements of the Bbl and relevant regulations
- Analysis of the risks and safety measures
- Assessment of the equivalence of the chosen solution
- Clear reporting of the findings
Applications of equivalence
Equivalence studies are used in a wide variety of situations.
For example:
Fuel-burning rooms
When combustion appliances are installed indoors or underground and the design deviates from standard regulations, we assess whether the chosen solution provides an equivalent level of safety.
Fire safety
Alternative measures can also be applied in the area of fire safety. Examples include sprinkler
systems, water mist systems, or other solutions that provide the same level of protection as
traditional structural measures.
This benefits your organization by providing:
- An independent assessment of your design
- Clarity for regulatory authorities and insurers
- Justification for alternative technical solutions
- Greater certainty during permitting and review procedures
- A solution that aligns with both practical realities and regulations
Independent assessment by Normec
An equivalence assessment requires specialized knowledge of building codes, installation
engineering, and fire safety. Normec’s experts combine these disciplines to objectively assess your situation.
Following a positive assessment, you’ll receive a clear report that allows you to demonstrate that the chosen solution meets the required performance standards. This increases your chances of a smooth review by municipalities, regulatory authorities, and insurers.

Frequently asked questions about equivalence assessment
-
An equivalence assessment demonstrates that an alternative structural or mechanical/electrical engineering solution provides at least the same level of safety as
required by law. -
This assessment is necessary when you deviate from the standard regulations of the Besluit bouwwerken leefomgeving (Bbl), but still want to demonstrate that your solution is safe.
-
Common applications include indoor boiler rooms, large combustion plants, and alternative fire safety systems such as sprinkler or water mist systems.
-
An independent assessment can be used to support claims made to competent authorities, such as municipalities, and to insurers.
-
Yes. Normec assesses the design, the risks, and the technical justification before determining whether an equivalent solution exists.
-
You will receive a clear report containing the assessment and justification of the equivalence of the chosen solution.
