RT Journal Article SR 00 A1 Chanampa, Mariana A1 Vidal Rivas, Pilar A1 Alonso Ojembarrena, Javier A1 Olivieri, Francesca T1 Systems of Vegetal Façade and Green Roofs used as a Sustainable Option in Architecture JF Design Principles and Practices: An International Journal YR 2010 FD 2010 VO 4 IS 2 SP 1 OP 10 K1 Ventilated Façade, Green Rooftop, Energy Saving, Bioclimatic Architecture, Green Wall, Evaporative Cooling AB Green architecture contributes not only in reducing the building’s thermal loads but also in reducing the effects of the urban heat island in densely built-up areas in a hardly natural environment. The current green systems are built in situ/on site and are very expensive, hence the need to create industrialized prevegetated systems which improve the buildings’ energy savings and reduce the times of construction works. The present paper describes three green systems for façades (gabion façade, green sliding panel, green panel in plastic cell) and two prevegetated green tank roof systems (green roof in light concrete and pvc).
