Buildings remain a technical matter

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. In the past the technical standard of a real estate in financial regards often has only been recordet in blurred comparative values. Now the technical standard becomes increasingly an autonomous topic within the sales process. For the buyer of an real estate otherwise would be made to take over a risk inestimable from him.

A certificate of energy consumption can give information about the range of the necessary measures. I can provide the necessary calculations, which for an appraiser is not naturally. Beyond that, as an architect I can plan the architectural measures which become possibly necessary. However, by the commercially oriented main focus of my activity I can give information on the expenses to be expected.

Above all, in concerns of the reconstruction, this combination of technical and business ability can become important. In the end, exceptions are possible according to the German Energy Savings Regulation (EnEV) §25: " if the necessary expenditure.... cannot be gained by the incoming savings within the usual time of use"

Already since the 2/1/2004 EnEV has to be applied, according which up to the 12/31/2006 the following requirements should have been fulfilled:

boilers that were installed before the 11/1/1978 should have been shut down
not isolated plumbing and armatures in not heated rooms should have been retrofitted,
the uppermost floor covers must be isolated so that a heat transfer coefficient of 0.30 W / m²K should have been reached.
boilers that were installed after the 11/1/1996 should have been shut down up to the 12/31/2008. Unless they fulfill further demands.

In order to the rising requirements more and more buyers insist on detailed information about the energy efficiency of a building. In the end, it is to be expected:

that with a legal entitlement of a tenant to indication about the energy efficiency of a building the tenant also will raise claims,
that on account of the goals to the climate protection the process of rising legal requirements will not be changed ,
that the energy prices will rise further
