The establishment and maintenance of the Energy Performance Certificate Database (EPCDB) is based on the EU Directive on the Energy Performance of Buildings (Directive 2010/31/EU). The Directive is implemented nationally by federal regulations as well as by corresponding regulations of the federal provinces.

According § 1(4) Statistics Austria has to set up a separate database (Energy Performance Certificate Database) as part of the Buildings and Dwellings Register for the electronic registration of energy performance certificates taking into account following requirements:

1. the energy performance certificates can be registered with their data in accordance with Section H of the Annex;
2. according to Section 5, the issuers of energy performance certificates have free access via the online application for the registering of energy performance certificates if federal province laws provide provisions for registration in this manner;
3. if federal province regulations provide the registration of the energy performance certificates in a federal province database, the registration has to be possible in the energy performance certificate database automatically via the online application (according to § 5);
4. in the course of registration and data recording, the BDR number will be generated by the application and made available to the issuers of energy performance certificates directly via the online application (according to § 5) or via the federal province database (according to Z 3)
5. the issuers have access to the data of the energy performance certificates issued by them if this is fereseen in federal province regulations.

According to § 7(2) – when requested – Statistics Austria has to provide free online access via the online application to the following data of the local Buildings and Dwellings Registers for all tasks relating to the fulfillment of statutory duties of a non-commercial nature:

1. the federal provinces to the data relating to the municipalities of the respective federal province in accordance with sections A to H of the Annex;
2. if an online access is provided according to federal province law, the issuers of energy performance certificates to the data according to sections B lines 1, 3 and 7 and section C of the Annex, if these data are required by issue of an energy performance certificate

The provisions of federal province law relevant to the maintenance of an energy performance certificate database can be found in the table below.

Further regulations in connection with the EPCDB

On 19 May 2010, the Directive 2010/31/EU of the European Parliament and of the Council on the energy performance of buildings (2010 Buildings Directive) was adopted and published in the Official Journal of the European Union on 18 June 2010 at L 153/13. The Directive specifies that an energy performance certificate has to be issued for new buildings in the case of extensive renovations, as well as for existing buildings when the building or a unit is sold or rented. Some of the previous regulations have been extended in their material scope. For example, when calculating the overall energy efficiency, an indicator for primary energy now has to be shown, as well as carbon dioxide emissions or an overall energy efficiency factor.

The civil law part of Directive 2010/31/EU is regulated by a completely new law. It replaces the Energy Performance Certificate Presentation Act (EAVG, BGBl. No. 137/2006 – available in German language only) that had been in force until then. The Energy Performance Certificate Presentation Act (EAVG 2012) explicitly regulates the submission of an energy performance certificate in the event of the sale or handover of buildings and units to their owners. New is that – according to the Building Directive 2010 – the indicator of energy performance and heating demand stated in the energy performance certificate has to be mentioned in the sales advertisement.

According to § 10 (1), the EAVG 2012 came in force on 1 December 2012.

The OIB guidelines serve to harmonize building regulations throughout Austria. They are published by the Austrian Institute for Building Technology (OIB) and adopted into building law by the provinces. The OIB Guideline 6 – Energy saving and thermal insulation (available in German language only) defines the requirements for energy efficiency of buildings.
