An energy certificate helps buyers and tenants judge about the energy efficiency of a building in a standardized way. House owners whose buildings were built before 1965 have to provide a energy certificate for tenants or potential buyers.
Rising energy prizes have become a second lease. This is why owners have the opportunity to increase their property’s value by renewing their buildings in term of energy efficiency.
Only trained professionals may provide energy certificates. These are architects, certain engineers and technicians from the construction industries. Craftsmen who can prove expert’s knowledge in energetical building refurbishment may as well provide the certificate.
The energy certificate ist valid for ten years.
The website of Deutsche Energie-Agentur GmbH lists all experts which are allowed to provide the certificate.
