Abstract

This paper shows how façade greening effects the heat resistance value on an old building. The façades of the building are made out of bricks. Two greened façades with different living wall systems have been researched and measured for one heating season. At the same time two not greened parts of the façade 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 façade 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 façades in winter. The improvement by the greening will be discussed within this paper.
