The energy declaration provides information about buildings' energy use to owners, tenants or buyers of a house, but also to the general public. Energy use often constitutes an important part of a building's operating costs. If there are suitable measures to be taken in a building to reduce energy use, proposals for such measures must also be included in the declaration. These recommendations can therefore constitute valuable information for owners of buildings, but also be interesting for those who, for example, are thinking of buying a house.
The purpose of the energy declarations is to promote efficient energy use and a good indoor environment in buildings.
