The implementation of an Epiclay green wall naturally leads to an aesthetic enhancement of urban space.
The mental well-being is strongly dependent on the individual perception of space and is influenced by the immediate surroundings. Studies have shown the strong influence of urban greenery on mental well-being, showing stress-reducing, blood pressure-lowering, attention-enhancing, concentration-enhancing and generally relaxing effects (Kaplan & Kaplan, 1989), but they can also lead to a reduction in aggression and anger (Die grüne Stadt, 2009).
Furthermore, green spaces have a positive influence on social well-being, as they lead to a perceived enhancement of the environment, for example in socially disadvantaged districts (Die grüne Stadt, 2009).
Furthermore, the physical health-promoting effect is also significant, as are aspects of environmental protection. Therefore, Epiclay’s goal is to provide sustainable greening of urban space, reduce air pollution and increase the energy efficiency of homes, while ensuring that city residents can enjoy the green environment.

To contribute to health and well-being, as one of our guiding SDGs, the composition of Epiclay plants has been chosen to provide the greatest possible benefit. Fine dust, pollutants and carbon dioxide are absorbed while oxygen is expelled. Heavy metals from car exhausts and industry can be accumulated. As already mentioned, pollution, which is sometimes severe, especially in cities, can lead to lung damage, asthma, fatigue and damage to the nervous system. It is therefore essential to integrate more plants into urban space, especially on facades, so that these areas are used sensibly (Die grüne Stadt, 2009).
One aspect that is often neglected in connection with health is the physical and mental stress caused by too much noise (Maschke, 2005). Epiclay is also used here, as the sound module and the plants have an insulating effect and therefore provide noise insulation.
In addition, the temperature in the building is regulated by evaporation, which leads to a more pleasant indoor climate, and to less use of air conditioning in the summer and heating in the winter months. (An advantage of Epiclay, however, is that the buildings are protected against moisture damage, compared to conventional greenery). The increasing use of air conditioning systems, due to Heat Island Effect in urban areas, but also generally rising temperatures caused by climate change, leads to a vicious circle. It is therefore important to counteract this now (Kikegawa et al., 2006).
The insulating effect of Epiclay modules is also closely related to the SDG Sustainable Cities and Towns. Increased insulation can increase the energy efficiency of buildings and reduce energy consumption. But the focus is not only on low resource consumption. For us, sustainability also means to provide more biodiversity in the cities. Green facades provide habitats for insects and small mammals, and maintaining them is essential for sustainable cities, even in urban areas.
