The energy certificate is a document that evaluates a building energetically. It gives you clues for a rough estimate of the future energy costs for an apartment or a house and makes the energy requirements of houses comparable. Energy certificates must be presented for new buildings and for the sale, leasing, rental or leasing of buildings. There are two types of energy passes. These differ in the calculation procedure. Energy requirements certificate The energy certificate is issued on the basis of the calculated energy requirements of the building. This procedure is mandatory for new buildings. This demand-oriented energy certificate calculates the energy demand on the basis of the condition of the building envelope and the building technology with an average user behavior. The simplified procedure collects data on a typology of the building shape, components, year of construction, etc., and the detailed procedure covers in detail the building to be examined and its building technology. Energy consumption certificate The consumption-oriented energy certificate reflects the weather-adjusted consumption of the building over at least the period of the previous three years. In certain cases, the result depends heavily on user behavior during this period. The heating and ventilation behaviour affect the result. Only qualified experts are entitled to issue energy cards. The requirements for the qualification of the exhibitors are regulated by law. However, there is no certificate or other certificate of entitlement to issue energy certificates. On the Internet, however, several site operators offer expert searches.

You must have the energy certificate if you want to rent, lease or sell the building. Owners, sellers or landlords who do not present an energy certificate, on time or incompletely face a fine of up to 15,000 euros.
