Energy supply, building works

Proposal for amendment to the Technical Building Works Regulations (TEK17) regarding energy supply requirements for buildings exceeding 1,000m2

The energy supply for buildings is regulated by the Technical Building Works Regulations (TEK17) Section 14, which have been in force since the 1st of January 2016. The requirement for energy supply is regulated by section 14-4. The second paragraph requires that any building exceeding 1,000 m2 heated floor space (BRA) must have multi-source heating systems.

It is proposed to specify and tighten the present requirement for multi-source heating systems. Specifically it is proposed to regulate that buildings exceeding 1,000 m2 heated BRA must have multi-source heating systems covering a minimum of 80 per cent of standard net heating requirement. This is an increase from the minimum of 60 per cent stated in the regulation guideline.

The requirement for 80 per cent will in practice mean that residential blocks (exceeding 1,000 m2) must have multiple source space heating. Alternative solutions can be selected for smaller parts of the heating requirement where appropriate. The proposal facilitates heating solutions such as district heating, heat pumps and bio energy.
