Certificate Unfortunately this specification of service has not yet been completely translated.

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 house and makes the energy requirements of houses comparable. Energy certificates must be presented in the case of new buildings and in the case of the sale, leasing, leasing or leasing of buildings. There are 2 types of energy cards. These differ in the calculation procedure. Energy demand 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 based on 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 details the building to be examined and its building technology. Energy consumption certificate The consumption-oriented energy record reflects the weather-adjusted consumption of the building over at least the period of the previous 3 years. In certain cases, the result depends heavily on user behavior during this period. The heating and ventilation behaviour have an effect on the result. Only qualified experts are entitled to issue energy cards. The requirements for the qualification of 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 present the energy certificate if you want to rent, lease or sell the building. Owners, sellers or landlords who do not present an energy certificate, not in time or incompletely, are liable to a fine of up to 15,000.00 euros.
