Energy Label

Energy labelling is a statutory classification of buildings on a scale from A to G that shows how energy efficient a building is. A is best and G is worst. Since 1 January 2026 the label is a single energy grade, calculated as weighted delivered energy per square metre of heated floor area. The former heating grade, shown as a colour scale, has been removed. Enova manages the scheme under energimerkeforskriften (the energy labelling regulations, regulation 2009-12-18-1665), which fall under the Ministry of Energy. NVE is the supervisory authority.

The duty applies when homes and buildings are sold or let, and to new buildings. The duty to label every building over 1,000 m² has been repealed, so for buildings used by private parties the duty now arises only on sale, letting or new construction. The duty rests with the owner. If an energy performance certificate is missing from the listing and the contract, the buyer can have one produced at the seller's expense within one year of the sale agreement. The energy label, or a simplified version of it, must be shown in adverts. Buildings where more than 250 m² is used by public authorities and that are often visited by the public must have a certificate. So must buildings where more than 250 m² is used by ministries, directorates and state supervisory bodies. Buildings over 500 m² that are often visited by the public must also display a visible summary of the energy performance certificate for visitors, under energimerkeforskriften § 8a. Some buildings are exempt, including detached buildings under 50 m². New buildings must be energy labelled before a completion certificate or temporary permission to occupy is granted.

The calculation follows NS 3031:2025 and is based on weighted delivered energy per square metre of heated UFA (usable floor area). Electricity and other energy carriers count with a factor of 1, while district heating, district cooling and biofuel count with a factor of 0.45. Exported energy, such as surplus solar power, counts as zero. Buildings that meet the energy requirements in TEK17 get grade B, and the limit for grade A is 15% below the TEK17 requirement. The grade shows normalised energy use under standard conditions, not actual consumption in a given year. Two identical houses with different occupants can therefore have the same label but different electricity bills.

For detached houses and small houses, the owner can register the energy performance certificate through Enova's self-service solution by entering information about the building. Commercial buildings and buildings with several dwellings must be labelled by a firm with engineering competence at bachelor level and at least two years of experience in energy calculations. The certificate is valid for up to ten years, but must be renewed after significant structural changes or changes to the technical systems that affect the label. Certificates issued under the old model remain valid until they expire. Grades from before and after 2026 are not directly comparable, because the method and the scale have changed.

The energy label matters financially beyond the duty itself. The label is used in screening for green loans at Norwegian banks (many banks require grade A or B for a cheaper mortgage) and in reporting under the EU taxonomy for commercial property. For BREEAM-NOR certification, the energy performance certificate counts towards the Energy category. In the valuation of commercial property, the rating is used more and more often as a risk factor: buildings with a poor energy label risk becoming "stranded assets" as tenants' taxonomy reporting drives demand for green space.

The reliability of the energy label varies. Self-registered residential certificates are of low quality and should not be used on their own as a basis for decisions in transactions. For commercial property where a certified expert has been involved, and especially where measured energy use deviates by less than 15% from the calculated figure, the certificate is a genuine diagnostic tool. In a condition report under the Sale of Property Act or a housing sale report, the energy performance certificate should be read together with actual energy consumption over the past three years. A large gap between calculated and measured consumption can indicate either errors in the registered building information or a pattern of use that differs significantly from standard conditions.

In Placepoint, the registered energy label is shown per building in the building panel, and you can filter the portfolio by label to find which buildings sit lowest in energy terms. Report: ESG and sustainability brings the energy label together with certifications, building regulations and climate related natural hazards in a single review.

Common questions we come across

When is energy labelling required?

On the sale and letting of homes and buildings, and for new buildings. The duty to label every building over 1,000 m² has been repealed. Buildings over 500 m² that are often visited by the public must also display a visible summary of the certificate for visitors, and buildings where more than 250 m² is used by public authorities and that are often visited by the public must have a certificate.

How long is an energy performance certificate valid?

Up to ten years from the date of issue, unless significant changes are made to the building or to the technical systems in a way that affects the label. A new certificate must then be issued. Certificates issued under the old model remain valid until they expire.

Can I energy label my house myself?

Yes. For detached houses and small houses, the owner can register the certificate themselves, with a simple registration, on Enova's website. Commercial buildings and buildings with several dwellings must be labelled by a firm with engineering competence.

What does the energy grade mean?

Since 1 January 2026 it is a single letter from A to G, calculated as weighted delivered energy per square metre of heated floor area. B matches the energy requirements in TEK17, and A is 15% below. The former heating grade has been removed, and the weighting of energy sources has taken over that concern.

What happens if the seller does not provide an energy performance certificate?

The buyer can order the certificate at the seller's expense within one year of the sale agreement. The omission can also form part of any price reduction under the Sale of Property Act.
