(3) Energy statements are issued for buildings. They shall be issued for parts of buildings if the parts of the buildings are to be treated separately in accordance with § 22. (4) Energy statements, including recommendations for modernisation, must comply with the content and structure of the designs in annexes 6 to 9, and shall contain at least the information required for the respective type of reference and not marked as voluntary. Additional, non-personal data may be added. In the case of energy, the exhibitor must sign his or her name, address and professional title as well as the date of the exhibition by hand or by means of a replica of the signature. Before handing over the newly issued energy certificate to the owner, the exhibitor has to enter the registration number assigned in accordance with section 26c (2). If, in the case of an electronic application, the registrant responsible in accordance with Section 26c has not received the application for a period of three working days from the date of application and, in other cases, the application until the expiry of seven working days after the application has been submitted. The registration number is assigned instead of the registration number the words "Registration number has been requested on" and the date of application to be entered at the registration office (preliminary energy certificate). Immediately upon receipt of the registration number, the exhibitor has to send the owner a copy of the energy certificate with the registered registration number. After access of the completed energy certificate to the owner, the provisional energy certificate will lose its validity.

If, in the case of decentralised domestic hot water preparation in residential buildings, the consumption resulting from this is not known, the final energy consumption is to be increased by a flat rate of 20 kilowatt hours per year and a square meter of building protection area. In the case of cooling of room air in residential buildings, the final energy consumption for heating and hot water is to be increased by a flat rate of 6 kilowatt hours per year per square metre of chilled building protection area. If the surface of the building is not known, it can be used for residential buildings with up to two residential units with a heated cellar flat with 1.35 times the value of the living space, and for other residential buildings with a value of 1.2 times the value of the living space. In the case of non-residential buildings, final energy consumption shall be determined for heating, hot water preparation, cooling, ventilation and built-in lighting, and shall be expressed in kilowatt hours per year and square metre of net land area. The final energy consumption for heating must be subject to a weather agreement. The primary energy consumption shall be calculated on the basis of final energy consumption and the primary energy factors set out in Annex 1, point 2.1.1, sentence 2 to 7.

Calculation of the year-Primary energy demand

2.1.1

The annual primary energy demand Qp is to be determined according to DIN V 18599: 2011-12, corrected by DIN V 18599-5 rectification 1: 2013-05 and by DIN V 18599-8 corrigendum 1: 2013-05, for residential buildings. The values for the non-renewable component according to DIN V 18599-1: 2011-12 are to be used as primary energy factors. For liquid biomass, the value for the non-renewable share of "heating oil EL" and for gaseous biomass shall be the value for the non-renewable part "natural gas H". For liquid or gaseous biomass within the meaning of section 2 (1) (4) of the Renewable Energy Heat Act, the non-renewable share of the value of 0.5 can be used when the liquid or gaseous biomass is in the immediate spatial Connection with the building is created. Sentence 4 shall be applied in accordance with buildings which are spatially interrelated and which are directly supplied together with liquid or gaseous biomass within the meaning of Section 2 (1) (4) of the Renewable Energy Heat Act. By way of derogation from the second sentence, for electricity, the primary energy factor for non-renewable energy shall be 1.8 from 1 January 2016; for the non-renewable component, the value shall be 1.8 for the non-renewable component; for the non-renewable component produced by combined heat and power generation plants and after deduction of their own requirements in the The combined electricity grid is without prejudice to the first half-sentence of the value of 2.8 specified in DIN V 18599-1: 2011-12. If a plant belonging to the building is used as a heat generator with combined heat and power generation, it is necessary to use the method B for its calculation DIN V 18599-9: 2011-12 Section 5.1.7 Method B. For the calculation of the annual primary energy requirement of the reference residential building and of the residential building, the marginal conditions set out in Table 3 shall be used. By way of derogation from DIN V 18599-1: 2011-12, in the calculation of the final energy requirement, those shares shall be set equal to "zero", the solar radiation energy and ambient heat obtained in direct spatial relationship with the building, and Ambient cold is covered.

If heated parts of a building are calculated separately, the first sentence of point (a) shall apply mutatily to the separation areas between the parts of the building. If the residential buildings are created at the same time, they may be treated as a building with regard to the requirements of § 3. The provisions of Section 5 shall remain unaffected.

2.7

Calculation of mechanically operated ventilation systems In the context of the calculation according to point 2, the calculation of the heat recovery or an air exchange rate reduced in terms of control technology is only permissible in the case of mechanical ventilation systems if:

a)

the sealing of the building in accordance with Appendix 4, point 2, is demonstrated; and

b)

the air exchange reached with the aid of the installation is sufficient to comply with § 6 (2).

The characteristic values of the ventilation systems to be used in the calculation of the heat recovery must be determined in accordance with recognized rules of the technology or can be taken from the general building-up authorisations of the products used. Ventilation systems must be equipped with devices which allow the user to influence the air volume flows of each user unit. It must be ensured that the heat obtained from the exhaust air is used primarily in front of the heat provided by the heating system.

2.8

Calculation in the case of common heating systems for several buildings A building to be erected is supplied with heat from a heating system, from which other buildings or parts of it also receive heat, it is different from DIN V 18599 :2011-12 and DIN EN V 4701-10: In 2003-08, in the calculation of the building to be constructed, it is permissible to adopt its own central heating facilities (heat generators, heat storage tanks, central hot water preparation), which are designed with regard to their design, their age and their construction age. However, the size and performance of the shared facilities shall be limited to the buildings to be calculated. To the extent that additional heat distribution and hot water pipes are laid for the connection of the supplied buildings, their heat losses must be taken into account in a proportional way.
