Already since the 10/1/2007 there is a so-called energy identity card for buildings in Germany. For residential buildings that were finished till 1965 , the certificate has become duty since 1st July 2008. For later residential buildings and for non-residential buildings this duty exits since 2009.

Especially on old buildings for which only a limited modernisation is planned there is the problem to do the calculations necessary for the certificate of energy-consumption. In addition the results have to be assessed, concerning the possible measures for heat insulation.

It has to annoy every site manager to fix dates and than just notice without any consequence, when these target dates have elapsed. If he acts like this he loses any possibility to take countermeasures when fixed periods are endangered.

A certificated quality management system according to ISO 9001 can become excessive bureaucratic , but the hundred-year-old experience of your partner is no guarantee for an actually existing selforganization, with tested expiries, tools and samples
