Abstract
The aim of this research work is evaluating energy saving and environmental
benefits of vegetal façades in comparison to traditional façades. In order to
achieve this objective, a particular type of vegetal façade has been studied and
installed in an experimental building. A similar façade without the vegetation
layer has also been installed in the same building in order to compare both
façade models. All the components of the two experimental façades are
monitored by state probes that register temperature data of the layers that
conform each experimental closing module in periods of five minutes. In
addition, a weather station that has been installed in the same experimental
building provides data about solar radiation, humidity, pluviometry, wind speed.
Results show that during summer time the temperature of those layers of the
façade with vegetation are lower than the one registered in the facade without
vegetation. The reason of this fact is that the temperature of the leaves is similar
to the one of the air, whereas the outside cladding is overheated due to the action
of solar radiation. In the case of winter, the vegetation layer goes on with its role
of a solar protection element and this means negative effects for the optimal use
of solar radiation in walling. In conclusion, the optimal use of these prototypes of
façades according to the climate of Colmenar Viejo (Madrid), whose climatic
characteristics are hot summers and cold winters, carries important benefits
related to comfort conditions in buildings. The way to optimize the system in
winter consists on the incorporation of deciduous vegetation in the façades
prototypes.
