Project Description
The effect of heatwaves caused by climate change are strongly amplified by high degrees of urbanisation thus challenging cities climatically - even in the temperate zone of Europe. High degrees of urbanisation are proportional to high degrees of sealed areas, preventing the extension of green space in inner cities, which are capable of improving microclimatic conditions, whilst providing habitat for insects. Green space being a rare resource, forces planers to revaluate and convert areas in use. The distribution and density of shelters of public transportation services offer ideal conditions for expanding green spaces to solve the given problems. However current concepts are having deficiencies.
The project “greenLEAF” targets these weak points with a more sustainable design and innovative structural approach. New vegetation systems for the shelters roofs and facades combine minimal structural loading with maximized transpiration cooling capacities. A choice of plants, which are low in demand, complemented by a self-sufficient irrigation system reduce maintenance requirements to a minimum. The construction being ecological is secured by the development of a cultivation substrate material that is biologically decomposable as well as recyclable. Statically active glass elements render common support components redundant, hence increasing material efficiency. With modular design and multifunctional units, it will be possible to adapt to individual requirements of the building locations up front as well as during the phase of service.
The development of a material-specific joining technology for the load-bearing glass is accomplished by small-scale experiments of adhesives, which characterise their thermomechanical and aging behaviour. The findings are incorporated into the development of a bonding adapter, which will be manufactured quality-assured by an existing assembly line. The adapter is essential for the realisation of modularity. Simulation models enable parameter studies for the development of comfort criteria as well as for the design of constructive elements, which will be subjected to extensive component testing, also resulting in a new safety concept that meet the conditions of the so far unknown state of stress.
