Energy-labelling of buildings
Energy-labelling of buildings is mandatory in Denmark. The aim is to promote energy savings by visualising the amount of energy that a building consumes and by outlining the energy saving possibilities.
In Denmark, it is mandatory to have an energy performance certificate (EPC) when selling or renting out buildings.
Buildings are labelled according to their energy usage
When a building is energy-labelled, it is inspected and measured by an energy consultant. On this basis, the energy consultant calculates the building’s energy consumption. The calculation is a measurement of the building’s quality in terms of energy usage vis-à-vis other buildings. It is a theoretical calculation, which can differ from the actual energy consumption that is depending on weather conditions and the habits of those who live in the building.
Energy-labelling works similarly to a consumer informative label. The energy performance certificate, furthermore, provides an overview of the improvements in terms of energy, which would make sense financially including the cost and savings that could be obtained.
Buildings are labelled from A to G
The energy-labelling scale runs from A to G, where A is divided into A2020, A2015 and A2010. A2020 covers low energy buildings, which only consume a minimum of energy, while G-labelled buildings consume the most energy.
