construct simple buildings without any involvement of an architect or engineer. The federal states, who define the expertship for new buildings in their building codes, did not want to have any difference between new and existing buildings in these cases.

Control of Certification

There will be no formal system of approval and certification for the experts, but a penalty is foreseen if an unauthorised person issues a certificate. In addition, building owners can be fined, if they do not make an energy certificate accessible to a prospective buyer or tenant. The federal states are responsible to follow up on the execution of the ordinance in general and to oversee the certification process, i. e. to assess possible penalties. This task is generally delegated to the local building authorities.

As there is no official register of experts, there can be no national register of issued certificates as well. On a voluntary basis, the German Energy- Agency (dena) runs unofficial registers of experts an of certificates issued by the listed experts.

Additional rules for Energy Certification

In contrast to new buildings, it often causes a large effort to determine details of construction, geometry and appliances of existing buildings. In order to provide experts with reliable data which can be used without any doubt as approximations, the Federal Ministry of Transport, Building and Urban Development has introduced two official announcements about simplified data recording simultaneously to the EnEV 2007. Furthermore two additional official announcements apply to the regional climate and to methods regarding the determination of consumption data including the procedure of neutralisation of the weather during the measuring period. The announcement applying to non-residential buildings also contains the reference values for different / mixed uses. Since the certificate is due to contain one value for heating and hot-water supply and one value for electricity, two reference values are also needed for each type of use. A few examples of reference values for metered consumption of non- residential buildings are shown in figure 6.

Building use (Examples)

Office buildings, heated

Office buildings, air-conditioned Hotels (medium class) Restaurants Cinemas

Shops, non-food, small Shops, food, small

Department-stores, air-conditioned Hospitals, large (> 1000 hospital beds)

Software for energy certification

The EnEV does not prescribe the use of any kind of software for certification. The development of software in Germany is left to a functioning market with mostly medium-sized competitors; the government does not want to intervene in this market. But concerning the forms of the certificates the software enterprises may take the advantage to implement a printing application into their products free of charge which has been developed by the German Energy-Agency (dena) with
