In April 2009 the KfW-Bank reorganised its promotional programme in the construction sector. The programmes now also have new names, for instance. The previous support programme “KfW-40” is now called the “KfW Efficiency House 55”. Raising the number wrongly suggests an easing of restrictions. With the introduction of the term Efficiency House, however the number that follows after the name had a new reference value. In the KfW 40 programme the primary energy requirement was not to exceed 40 kWh per m2. For the support programme KfW Efficiency House 55 the primary energy consumption and the transmission heat loss are to be max. 55 % of the level permitted in the Energy Saving Regulation. The requirements are therefore de facto about the same. However, just a few months later, on October 1, 2009, the new EnEV 2009 came into force with substantially more stringent requirements. The promotional programme therefore had to be readjusted and extended accordingly. There were further updates on 01 July 2010 und 01 March 2011.
