International ÖKOBAUDAT activities

The life cycle assessment of buildings can not be considered limited to the national level. The method is internationally recognized and standardized; In many EU Member States, EPD programmes have been established in accordance with ISO 14025, which generate their EPDs compliant with EN 15804. For this reason, the ÖKOBAUDAT team is integrated in an international network. ÖKOBAUDAT is used worldwide for LCA of buildings. Selected examples for the use in building assessment systems are Green Building Council in Denmark and LENOZ by the Ministry of Housing in Luxembourg.

Among the accepted suppliers of EPD data are also EPD programme operators from abroad, such as the Austrian Bau EPD GmbH, other European EPD programme operators are currently applying for recognition. With the European association of EPD programme operators, the ECO platform, ÖKOBAUDAT has been exchanging information and rules since its establishment.

An important aspect for the BBSR as operator of the ÖKOBAUDAT is the international harmonisation and standardisation. Therefore, delegates represent the BBSR in all major standardization committees, such as CEN / TC 350 Sustainability of construction works, Mastermind of EN 15804 Product Category Rules for Construction Products, or ISO / TC59 / SC17, which develops a standard for the application of Environmental Product Declarations in Building Information Modeling (ISO / WD 22057 Enabling use of Environmental Product Declarations (EPD) at construction works level using building information modeling (BIM)). Research results regarding data format and method have been regularly exchanged with the Joint Research Center.

Internationalisation is being driven forward by commissioning research projects:

  • 2016: ÖKOBAUDAT and Europe (SWD -
  • 2017: ÖKOBAUDAT and Europe II (SWD -
  • 2018: International networking of Ökobaudat (SWD -

Research results around the ÖKOBAUDAT are regularly presented at scientific conferences in Germany and abroad, e.g. at the SBE16 Conference Hamburg, the WSBE 2017 in Hong Kong or the LCM Conference 2017 in Luxembourg. The ÖKOBAUDAT presentation in Barcelona 2014 finally led to the founding of WG InData, the International Open Data Network for Sustainable Building, initiated by BBSR.

To support international cooperation, all website content is also available in English. Since 2018 the generic datasets are fully available in English.

International data search

In the research project "ÖKOBAUDAT and Europe II" an international networking of EPD databases with distributed search function was demonstrated.

This screencast shows how multiple database nodes (such as the ÖKOBAUDAT), which are operated by independent data providers, can be used to form a data network. On such a network, a distributed search can be initiated that will retrieve matching results from all the member nodes.
The screencast was developed within the project "ÖKOBAUDAT and Europe II", as well as the bilingual sample data and the demonstration network with three demo nodes. The shown functionality is foreseen to be used to build the international data network which is planned by the InData Working Group.
