The trend of urbanism in the cities is to reduce the amount of green areas. These green areas cannot compete with the financial force of developers, and therefore they are built in a vertical shape instead of the horizontal one and as a living wall system (LWS). In this form, they are able to reduce the urban heat island (UHI) and have positive effects on building improved thermal environment as well as other benefits. Unfortunately, there are still areas, such as historic centres of towns, squares and parking slots, where no areas are suitable for the living wall system. On the other hand, specifically these areas are suitable for the mobile version of green walls. This study examines the influence on lowering the temperature of the mobile version of LWS developed at the Mendel University in Brno. The evaluation is based on comparing the surface temperature of buildings, the surface temperature of LWS while dry and the surface temperature of LWS after irrigating. The effect was observed in the thermographic pictures of the mobile version of LWS by comparison to the reference wall. The study aims at evaluating the real possibilities of the LWS system on lowering the temperature of surfaces in the urban area as well as the possibilities of the system on lowering the problem with UHI. The results confirmed the expected lower temperature of the surface approximately about 13,2 % at LWS while dry and 28 % after irrigation in comparison to the regular surface without LWS cover. Similarly, the effect of balanced extreme temperatures during the day was examined, as the irrigation water was able to remove the high temperature of the LWS surface and significantly contributed to the cooling effect. Moreover, there was no radical stress level of plants recorded on the vertical green mobile system. Otherwise, that would negatively affect the positive functions of such solution.
