Abstract
In order to obtain data on the behaviour of green facades in buildings as a passive system for energy savings
in dry Mediterranean Continental climate a long-term work has been performed. This paper presents
the first results of two actions developed during 2009. First, the growth of four different climbing plants
as well as their ability to provide shadow was studied. Second, monitoring for a year of a real green facade
was carried out. The results confirmed the great capacity of green facades to produce shade, reducing the
heat on the facade wall of the building. It was also verified that a microclimate between the wall of the
building and the green curtain are created, characterized by slightly lower temperatures and higher relative
humidity. This means that the green screen acts as a wind barrier and confirms the evapotranspiration
effect of the plants. On the other hand, these results did not allow withdrawing conclusions about
the insulation effect of green facades.
