What is the KfW?
The KfW (Kreditanstalt für Wiederaufbau) is a national public-law development bank which pursues a statutory state mandate and is therefore not to be understood as a credit institution within the meaning of the German Banking Act. KfW offers an extensive promotional programme in the real estate sector, which includes the acquisition or construction of owner-occupied homes and the energy-related renovation and modernisation of buildings and living space. The promotional loan Energy-Efficient Construction defines the KfW Efficient House as an energy standard with levels 40, 55, 70, 85, 100, 115. The lower the level, the more energy-efficient the property. The purchase or construction of a KfW Efficiency House is supported by a low-interest loan with a repayment subsidy (partial remission of the loan) depending on the energy efficiency.
KfW offers two options in the Energy Efficient Renovation promotional programme:
– renovation to become a KfW Efficiency House or
– the implementation of individual energy-related measures.
Low-interest loans and grants as well as redemption grants for the renovation of a KfW Efficiency House are key elements of this support.
The thermal insulation requirements for a KfW Efficiency House are of fundamental importance and are achieved, among other things, by installing suitable windows and doors with a low heat transfer coefficient.
