This thesis deals with the current situation of facade greening in Austria as well as in Europe. It should give a general view on to innovative fields as well as prospective chances. The writer herself works for the austrian green roof association (V.f.B.) as well as for the european federation of Green Roof Associations (EFB). Due to her projectwork as study assistant for the Institute of Soil Bioengeneering (BOKU Vienna), she was able to gain experience on to facade greening. She decided to reprocess and evolve gained knowledge by working on this thesis. Facade greening in Austria now expiriences a huge development trend, this thesis expects this trend to evolve into a future trend very soon. Based on two different pilot projects: -„CLIMATE PROTECTION FACADE“ of Company Brothers Haas (GEHA), Guschelbauergasse 3, 1012 Vienna -Facade greening system of Companies Mischek/BauXund and EBG, Kammelweg 8, 1012 Vienna approaches were conducted to: plant physiology (coverage ratio, vitality, losses), water regime (simulation of heavy rain impact, graywater adsorption filter, analysis of roofwater) and engeneering in theory (material, construction, plant selection). Fine dust measurement and the ecological footprint were discussed in theory. Those results are meant to give an overview on to the current „state of the art“ of facade greening and find weaknesses as well as improvements. Prospective research questions and attempts can be excluded or proposed. This theory also contains best practice proposals for building contractors and landscape architects. From the official site, only one german FLL guideline to „planning, realization and maintenance of facade greening“ exists at the moment. To give guidance to planning organs, standards have to be found and defined. This thesis creates a draft on to a possible valuation method to classify and certify facade greening systems. Valid roof greening documents of the V.f.B. as well as the new ÖNORM L1131 served as a model for the process. Finally, potential development proposals targeted on both pilot projects are offered. Those proposed changes affect species structures and target group definitions, if conducted, they could have a positive effect on future trends.
