The ÖKOBAUDAT platform is provided as a standardized database for ecological evaluations of buildings by the Federal Ministry for Housing, Urban Development and Building. At the platform's core is the online database with life cycle assessment datasets on building materials, construction, transport, energy and disposal processes. With the help of life cycle assessment tools, such as eLCA provided by the BBSR, the entire life cycle of a building can be reconstructed with the ÖKOBAUDAT database. ÖKOBAUDAT is not designed for performing life cycle assessment of building products.
The datasets are subject to strict quality requirements and can be used in many different building assessment systems. The database system with its search and filter functions enables user-friendly online searches of the datasets.
Data published in ÖKOBAUDAT are publicly available at no charge. The respective owner of the datasets remains responsible for the contents and values.
More than 1400 datasets for building products - EN 15804- and BNB-compliant
The constantly updated ÖKOBAUDAT (current version 2023-I from 15.06.2023) is the mandatory database for the Assessment System for Sustainable Building (Bewertungssystem Nachhaltiges Bauen, BNB). Datasets are provided for the relevant building products, in compliance with DIN EN 15804.
ÖKOBAUDAT offers both generic datasets and specific environmental declaration datasets from diverse companies or associations. EPD datasets in ÖKOBAUDAT must fulfill further requirements beyond the scope of EN 15804 (see Principles for acceptance of LCA data in ÖKOBAUDAT). Before approval, the EPD programmes and data are checked for conformity with ÖKOBAUDAT requirements (→ Guidance for data providers).
Datasets in ÖKOBAUDAT are based on the background database GaBi. Besides, datasets based on ecoinvent background data are provided in 'additional datasets'. These are only by exception to be used within the Bewertungssystem Nachhaltiges Bauen für Bundesgebäude (BNB).
ÖKOBAUDAT is currently available in two versions: 'ÖKOBAUDAT according to EN 15804+A1' and 'ÖKOBAUDAT according to EN 15804+A2'.
Environmental product declarations (EPDs) that were created after October 1, 2022 according to the EN 15804:2012+A1 standard are no longer included in ÖKOBAUDAT because they do not conform to the standard.
The generic data sets are only commissioned according to EN 15804:2012+A2:2019. The generic data sets, which were created according to EN 15804:2012+A1, are no longer updated, but are made available for ongoing projects in the 'ÖKOBAUDAT according to EN 15804:2012+A1' tab until further notice.
