mandatory by a certain date - which in many cases has already expired.

Considering these circumstances, Germany has chosen to implement according to „option b“, because the additional introduction of a mandatory inspection of heating systems was considered not justifiable. Among other actions the German Energy-Agency will carry out a campaign (prepared in 2007 with support of the Federal Government) to inform the citizens about the possible improvements of heating systems. In addition, there are subsidy programmes as well as campaigns of other parties.

Maintenance duties became mandatory for air-conditioners which includes from the German point of view also the testing of the nominal conditions of energetically relevant components by the maintenance technician. Furthermore, every air conditioning unit with more than 12 kW rated thermal output has to undergo an inspection by a specialized engineer every 10 years. The engineer has to inspect the appliances with respect to proper dimensioning and state of the art. He has to provide recommendations for cost-effective improvements to the owner.

European Standards

Germany will not make any use of either the calculation standards or the inspection standards released by CEN under the EPBD mandate. The main reason for this decision is that the CEN-standards were not yet available when the ordinance was designed. A national procedure had therefore to be developed. There were also serious reasons to keep the old procedure - introduced in 2002 - in place for residential buildings. Furthermore, the recently published CEN-standards show a need for improvement as it lacks of a holistic approach. In order to make them applicable, their enormous extent must be reduced significantly, because by the addition of national conditions for climate and use it would even become larger.

Principally, the German approach via reference buildings allows the additional use of a consolidated set of CEN standards at a later stage.

Considering the recent findings about climate change, the German Federal Government decided in summer 2007, that – among other actions – the Energy Saving Ordinance shall be amended once more in order to strengthen the requirements by 30 % in a first step. In 2012, another step of the same size shall follow.

The amendment of the „Energieeinsparverordnung 2009“ is due to enter the legislation process in May 2008. The target is to adopt the new ordinance before the end of this year.

With every amendment of energy requirements the government has to take the legal rule into account according to which all requirements have to be economically reasonable. Especially because of the significant rise of energy prizes it can be proven that the expenditures caused by the strengthened requirements will be amortized within an few years by energy savings.
