Energy performance certificates

When is an energy performance certificate required?

An energy performance certificate is required for existing buildings in the context of a sale or renting . For new buildings, an energy performance certificate is needed during the building permit phase and it should be confirmed before building's commissioning. An energy performance certificate is not needed when changing the use of a building, for holiday homes, or for buildings smaller than 50 m².

 

In some cases, a simplified energy performance certificate procedure may apply. You can contact us for more information.

What does an energy performance certificate include?

An energy performance certificate indicates the energy efficiency of a building, allowing comparisons between different buildings. The energy efficiency comparison is based on the E figure, which is tied to the building's energy rating on a scale from A to G. The E figure is calculated based on the building’s annual energy consumption per square meter of heated net floor area. The energy performance certificate also includes recommendations for improving the building's energy efficiency.

How is an energy performance certificate created?

An energy performance certificate is created for the entire building, with some exceptions. The certificate is based on an inspection, which assesses the energy technical condition of systems and building components. The inspection primarily involves reviewing the building's documents, with additional information gathered and verified through interviews with users.

.

When the energy performance certificate is prepared for an existing building, an on-site inspection is required. During the visit, the building is evaluated from an energy efficiency perspective without dismantling structures, and potential areas for energy savings are identified. This allows for targeted recommendations to improve energy efficiency and helps reduce costs.

Energy reports

When is an energy report required?

An energy report is required when applying for a building permit for new construction and sometimes also in connection with a change of use or permit-required renovations.

What does an energy report include?

An energy report is a more comprehensive analysis of a building's energy use.

 

An energy report typically includes the following sections: 

• the building’s E figure and the key data and results used in its calculation

• An assessment of the building's compliance with regulations regarding heat loss

• Calculation of the ventilation system’s specific electricity consumption

• An energy performance certificate, if required for the building

• An estimate of the building’s actual energy consumption

• An estimate of the heating power requirements

• An estimate of the indoor temperature during the summer months

• If necessary, an estimate of the cooling power requirements.
