Consequences of the proceeding climate change become more and more perceptible in urban spaces due to increasing soil sealing and heat retaining and emitting buildings. Transpirational cooling and shading by plants are important factors to attenuate urban heat spots. However, urban canyons do neighter provide enough space nor soil acess for climate adapted trees and shrubs to establish a climatically effective green infrastructure. Therefor, we have to attract notice to the importance of vertical greening for climate control. The successful previous project `Klima-Forschungs-Station‘ showed that the combination of green walls with innovative materials for facades (ZAE Bayern) facilitates cooling in summer and isolating the green building in winter time. Previous aspects of vertical greening mostly focused on functionality, climate effectivity, maintenance costs and optical conditions. Moreover, with a suitable arrangement, formerly overheated and dead facades could be transformed into diverse living habitats for plants and animals. To stabilise pollinator populations, particularly wild bees, and enhance biodiversity, it is essential to provide rich and long flowering plants as food source along with nesting sites. For this reason, habitat and climate adapted, long flowering, bee friendly shrubs will be tested for their suitability in vertical greening systems. With focus on biodiversity in urban ecology also mobile habitat modules e.g. nesting sits with appropriate nesting materials for wild bees should be directly integrated within the vertical plant systems. Bee acceptance and compatibility with commercially available green wall systems, plant performance, climate effectivity, energy efficiency, maintanance costs and contribution to urban biodiversity with focus on wild bee populations will be evaluated. The overall objective is to establish species-rich, climate effective green building envelops for practical use in facade greening.
