This paper presents a classification of green vertical systems for buildings. The aim of this classification is
to facilitate the identification and differentiation between systems. This classification is also essential to
compare future research results relating to their operation. In addition, the mechanisms by which green
facades can be used as passive energy savings systems are reviewed: shadow produced by the vegetation,
insulation provided by vegetation and substrate, evaporative cooling by evapotranspiration, and the barrier
effect to the wind. Finally, the paper describes the first results about the behaviour of a double-skin
green facade or green curtain in Dry Mediterranean Continental conditions. It is verified that a microclimate
between the wall of the building and the green curtain is created, and it is 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.
The work was partially funded by the Spanish Government
(Project ENE2008-06687-C02-01/CON) and the European Union
(COST Action COST TU0802), in collaboration with the Cityhall of
Golmés and Fundación Mapfre. The authors would like to thank
the Catalan Government for the quality accreditation given to their
research group (2009 SGR 534). |
