Short description of the intervention
The experimental green facade system consisting of four different types of green wall was installed in Nurnberg from 2013 until 2016 on Adolf-Braun-Strasse 33 and is an integrated greening system that enables self-sufficient, low-maintenance "hanging gardens" on facades and other vertical walls. The aim of the project is to experiment with recreating green spaces in the streets, asphalt surfaces, and backyards of some parts of Nuremberg overcoming numerous constraints and competing uses (1) The implementation has helped improve air quality, thermal insulation, wind and rain protection and lowering local temperatures in its proximity.

Goals of the intervention
1. To study the possibilities of installation of the green facade systems in the free spaces of Nurnberg and to become as a decision-making aid for the city of Nuremberg in establishing vertical green roofs for future construction measures. (1, 4)
2. To reveal types of biotopes that are the most suitable for Nurnberg climate (1)
3. To increase the amount of green space in Nurnberg and thus increase aesthetic appreciation (1)
4. To introduce a tool for natural cooling of the area in densely built areas and improving thermal insulation of buildings (2)
5. To decrease the noise effects in the area (2)
6. To improve the air quality (2)
7. To provide protection from wind and rain (2)
Quantitative targets

Climate change adaptation: What were the goals of the NBS?
Implementation activities
Four green walls of different systems were installed on the wall of the City Drainage and Environmental Analysis Nuremberg (Stadtentwässerung and Umweltanalytik Nürnberg) (2)
These systems were:
1. Humko von Wolf: plastic panels with plant openings and substrate
2. Vertiko: aluminum composite panel with fleece pockets and substrate
3. 90 degree: fiber mat on carrier plate with fleece pockets and no substrate
4. Fassadengrün von Optirün: aluminum square grid with plant openings and substrate (4, 5)
Please specify other type of green wall

Type of innovation
Please specify technological innovation
The test green areas were installed on a ventilated façade on a solid substructure, which is anchored in the load-bearing wall. The wall contains different fleece-laminated cassettes, formed of aluminum mesh or plastic, filled with substrate. An irrigation system is integrated and is supplied and monitored via a small supply station with water and fertilizer. Depending on the orientation and requirements, the modules are planted differently (1)

Impacts, benefits
Description of environmental benefits
According to the municipality of Nürnberg, temperature in the space surrounding the green facade stabilized during the period of the project. (3) The vertical greens improved air quality, thermal insulation, wind and rain protection and lowered local temperatures. The walls also helped absorb sound and thus reduce noise impact of the buildings they were locate on. (2) The amount of green space in the area increased without having to sacrifice large areas for green space. (3)
Economic impacts
