This research is part of a project that aims to create a simulation workflow to design
adaptive facades to not only reduce the energy demand of buildings and provide a good level of
indoor comfort, but also to mitigate the urban heat island effect. The anthropogenic climate
change results in a steady increase of hot days, tropical nights and heavy rainfall, affecting the
quality of human comfort, especially in urban areas not only in hot regions of the world but also
in Central Europe. Vertical greening systems are often a first-choice mitigation strategy to im-
prove the deteriorating situation. By combining the use of natural resources like rainwater and
solar radiation, the greening evaporates water and provides natural cooling. This paper deals with
the efficiency and feasibility of vertical greening systems towards a relief in heat stress by sim-
ulating different constructions under local circumstances of three climate zones, focusing on the
night-time. To carry out the simulations with microclimate simulation tool ENVI-met, an urban
apartment complex was designed and provided with different kinds of vertical greening to in-
vestigate the various positive effects resulting from the green façade. As a shading device, the
greened walls showed a significant decrease of wall surface temperatures of up to 18K. However,
restricted transpiration fluxes obstruct exploiting the full potential of evaporative cooling, espe-
cially during night-time.
