Renewable Energy

Section 14-4 Energy supply requirements

1)   The installation of fossil fuel heating installations is not permitted.

2)   Buildings with heated usable floor space (BRA) of more than 1,000 m2 shall

a)  have energy flexible heating systems,

b) adapted for the use of low temperature heating systems.

3) The requirements in the second paragraph does not apply to small houses.

4) Small houses must be constructed with chimneys. The requirement does not apply if

a) the house is constructed with a central heating system, or

b) yearly net energy need for heating does not exceed the requirements for passive houses, calculated in accordance with Norwegian standard NS 3700:2013 Criterias for passive houses and low energy houses.
