This paper shows how facade greening effects the heat resistance value on an old building. The facades of the building are made out of bricks. Two greened facades with different living wall systems have been researched and measured for one heating season. At the same time two not greened parts of the facade were measured. So far there does not exist any general method, how to calculate the U-value or particular heat resistance values of the greened facades. The method which is developed within this research-paper makes the comparison between the greened part of the facade and the not greened part possible. It turned out that there is a difference of the thermal resistance between greened and not greened parts of the facades in winter. The improvement by the greening will be discussed within this paper.

This paper shows the results of a project that investigated the humidity of the air in the ventilation gap of a green façade system. The systems which were investigated are made of aluminium troughs, aluminium modules, or fleece. These systems are mounted on metal rails. The metal rails connect the façade with the plants. This creates a curtain façade that is ventilated by air. The humidity of the air in the gap was investigated, and this paper shows the results of the investigation.

One of the strategic goals of Europe 2020 is the reduction of greenhouse gas emissions by 20 % by 2020 compared to year 1990 and increasing energy efficiency by 20 %. Closely related to the revitalization of structures necessary for reasons reduction of their unsatisfactory energy consumption and then also the construction of new building structures with minimal energy requirements by using less energy demanding materials, if is it possible from easily renewable resources. Currently, the structures involved a high degree of total energy consumption in the European Union, about 40 %. Thermal insulating plasters with using lightweight aggregate based on recycled glass are the appropriate remediation materials for the rehabilitation of existing buildings, or even for thermal insulation of new structures. In view of the fact that historic buildings are often exposed to dampness and moisture, it is necessary for these redevelopment plasters also tackle studios moisture transport. The paper describes the results of the development of new insulating plasters that would have been reflected particularly in the rehabilitation of historic buildings and problematic details of building structures.
