The most economical and environmentally friendly building (KfW Energieeinsparverordnung 40) Gets the highest repayment subsidy of 10% of the loan amount as cash available. The Federal Office of Economics and export control (BAFA), in addition to the existing programmes of the KfW promotes innovative technologies for the heat generation with renewable energy sources. In so-called BAFA promoting innovation promoted, for example, solar collector systems for hot water and heating support. Financial incentives are also paid in the combustion of biomass in combination with condensing technology. A wood pellet burning value heating would be, for example, an accordingly eligible generators. To investigate what the energy efficiency measures are sensible and feasible, promotes the BAFA on-site energy advice and subsidised them with half of the consultancy costs incurred up to a maximum of 350. The results of the investigation are in Opinion standard represented a large volume. Prerequisites for applying for subsidies is to create a demand-oriented certification, which takes into account the planned efficiency measures and determines the appropriate request values for building envelope and primary energy demand.

This certificate can be created free of charge, for example, with different variants of modernisation on the Internet portal the IB Cornelsen. It queried the necessary input data according to the guidelines of the Federal Ministry of transport, building and urban development (BMVBS) online. If you opt for a modernisation concept, can be drawn to an engineer if necessary which examine the energy performance certificate on consistency and issue an original card. This should be submitted together with the application forms of the corresponding programmes. The growing acceptance of innovative environmentally friendly technologies, as well as the continuous improvement of energy efficiency in buildings is remarkable in Germany. The IB Cornelsen provides interesting statistics that underpin this development, from a data pool of 16,000 buildings analyses conducted.
