Public targets and funding sources
To deliver quality-assured greening of buildings, clear targets and grants from the public sector as well as industry-generated minimum standards will be helpful. The following overview is continually updated with the latest developments.
Things you need to know about public sector targets and grants
A range of instruments and targets for the delivery of green buildings exist in Austria. Legislation of the federal states is the legal foundation for local and reginal spatial planning. The delivery of local spatial plans is the responsibility of local parishes according to the national constitution. The respective targets and provisions at the level of the local spatial plan apply. These are governed by local regulations.
The implementation of greening buildings is also embedded in national strategies and policy documents that vary in their reference to local areas, for example:
- Biodiversity Strategy 2020+ (In German), Environment Agency, Austria
- Bio-economy strategy 2020+ (In German) Federal Ministry for Sustainability and Tourism, Austria
- KLIMAAKTIV (In German) Federal Ministry for Sustainability and Tourism, Austria
- Climate change adaptation strategy (In German) Federal Ministry for Sustainability and Tourism, Austria
- #mission2030 (In German) Federal Ministry for Sustainability and Tourism, Austria
- Renewable Energy 2018 (In German) Federal Ministry for Sustainability and Tourism, Austria
- City Development Plan STEP 2025 (In German), green and open space strategy, City of Vienna
- Environmental declaration 2018 (In German) Federal Ministry for Sustainability and Tourism, Austria (In German)
- Urban Heat Island Strategy UHI-STRAT (In German), City of Vienna
Grants for the implementation of green building measures are available across Austria as part of the house building program (bonus points) and also directly from cities’ own funding sources (green measures, urban renewal) for different target groups (Graz, Vienna, Linz).
Grants for street-side green and living walls Vienna (up to 5000€)

Eco-business plan Vienna (for businesses)
Ecological business advice Niederösterreich (for businesses)

Developing standards for greening buildings
In Austria, the Austrian Standards Institute (ASI) is responsible for developing standards. For greening buildings there are already two established standards. They should be considered as a voluntary minimum standard for implementation of green building projects. In some cases, they are a condition for receiving grants.
- ÖNORM L1131 für Dachbegrünung (2010) (for green roofs)
- ÖNORM L1133 für Innenraumbegrünungen (2017)(for interior green and living walls)
For the technical area of green and living walls, the ÖNORM L1136 vertikale Außenbegrünung (vertical greening) will shortly be available.
State of the art technology
Beyond applying the standard, the respective state of the art technology can be applied. The experts take guidance for assessments and damage report using the commonly available supporting guidelines and regulations. For the area of greening buildings the following are recommended:
Swiss Standards Institute (SNV)
- Sia SN 564 312 Dachbegrünung (2013) (for green roofs)
Research Institute for Landscape development and Landscaping (FLL)
- FLL Dachbegrünungsrichtlinie (2018) (green roofs guidelines)
- FLL Fassadenbegrünungsrichtlinie (2018) (green and living walls guidelines)
- FLL Innenraumbegrünungsrichtlinie (2011) (interior green walls guidelines)
