We Test Green Facades for Industrial Spaces


In the laboratories of the University Centre of Energy-Efficient Buildings of the CTU in Buštěhrad, we have been monitoring the hygro-thermal performance of three different solutions of the external wall of industrial hall objects since the beginning of July of 2019.

The aim of the research project is to find out how plants and mass of soil substrate influence the hygro-thermal performance of the perimeter wall. The results will be compared to data measured in two reference wall constructions which are commonly being used for hall constructions at present. Another aim of this long-term experiment is to improve the irrigation system of the green facade.

A climatic room with controlled indoor environment is used for tests. This room is equipped with an automated system for recording the data from test fields and for measuring local micro-climatic conditions in the vicinity of the facade. The wall of the climatic room is furnished with six test fields of the size of 3 m × 3.2 m where real-size models of the perimeter construction can be built. The south-west-oriented wall is exposed to the effects of real climatic conditions from the outside.

Two test fields next to each other are used for the experiment. In the first one, two standard types of external walls are built (either ventilated or unventilated metal cladding on the thermal insulation placed in between metal studs). The outside trapeze metal sheet is replaced with a green facade in the second test field. The pre-planted greenery was provided by the LIKO-S company.
