3.Data quality and limitations
Rating: Medium — Gas calorific basis assumed; Only NRF published; Wohnfläche and AN unavailable; Energy costs not published; Heating consumption weather-adjusted by source.
Statuses are screening indications from the entered data, not legal advice. Verify the promulgated statutes and individual exemptions with qualified professionals. An Energieausweis may only be issued by authorised issuers.
