Abstract
The thermal performance of Traditional Green Facades (TGF) vegetated with perennial climbing species in the summer season in the Metropolitan Area of Mendoza, Argentina, located in an arid climate, is evaluated. To this end, outdoor air temperatures in the mediate and indoor microclimate in an air chamber, and exterior and indoor surface temperatures were monitored for a period of 30 days in an experimental trial. It is composed of three masonry walls, two with TGF and the remaining core without vegetation cover, oriented to the west and isolated on its N, S, and E faces, housing an air enclosure in the latter orientation. Temperature reductions of 3.5 °C were found in the air of the outside environment at 30 cm from the wall, 6.2 °C in the inner air chamber, 17.8 °C on the surface of the outer face, 7.5 °C on the surface of the inner face and up to 2.0 °C of variation between the FVTs with different plant species. These values demonstrate the potential of implementing the strategy on temperatures in their immediate environment and indoor spaces. In addition, it is observed that the magnitudes of these impacts depend on the type of plant structure and are greater in arid climates than those reported for other climates in the international literature.
