This paper presents the results of the analysis on the impact and influences of the (BF) temperatures. The MFS is an ongoing project-development. It combines two well-known systems: photovoltaics (PV) and green façades (GF). The simultaneous use of PV and GF creates a green buffer (GB), which acts as an insulation tool for the PV and the BF. In addition,the MFS protects its components, the GF, the PV and the BF, especially from extreme temperatures. To validate the influences of the MFS, similar systems were setup with variations
on the GB: with and without a GF. The assessment was based on the comparison of these systems with a bare wall. Findings revealed temperature reductions on the BF of up to 30°C and an average of 21.4°C for the maximum temperatures. In winter, it limits the cooling down
effect of the wall by about 3°C on average, when outdoor temperatures drop below 0°C. The presented results correspond to the first period of research: from July 2015 to November 2016.
