Understanding the Norwegian Building Code

The Norwegian building code is a function-based Building Code

TEK (the Norwegian Building Regulation) is largely a function-based regulation. This means that the technical requirements are specified in the form of either functions or performance in all essential areas.

 Function requirements are described in the guidelines to the Norwegian Building Regulation in the form of qualitative or quantitative performance. These qualitative or quantitive performances are designated as pre-accepted performance. This means that by complying with these pre-accepted performances you are deemed to comply with the Norwegian Building Regulation.

 In the areas in which TEK expresses requirements for functions, pre-accepted performance in the guidelines must express measurable performance or verifiable quality.

 Example:

TEK Section 13-7. Section 13-7 states that structures must be designed and constructed so that noise levels from impacts and structure-borne noise from a user area are so reduced that other user areas are ensured satisfactory acoustic conditions. The guideline establishes pre-accepted performance: In this case, Noise Class C in NS 8175:2012 Acoustic conditions in buildings - Sound classification of various types of buildings meets impact noise insulation requirements
