Desempeño térmico de fachadas verdes tradicionales de orientación este en viviendas seriadas emplazadas en climas áridos

Abstract

Green infrastructure is a strategy for mitigating urban and building temperatures. This work assesses the impact of a type of Vertical Greenery System (VGS), the Traditional Green Façades (TGF), on the thermal condition of dwellings located in the Metropolitan Area of Mendoza, Argentina, whose climate is dry desert (BWk - Köppen-Geiger). To this end, two case studies were monitored for two consecutive summers: a dwelling with an east-facing TGF and a control dwelling of the same typology and materiality. Outdoor and indoor ambient temperature data were recorded: surface exterior and interior, and horizontal radiation. Decreases of up to 3.1°C in the indoor ambient temperature of FVT dwellings, of up to 27.4°C on exterior walls and 6.5°C on interior walls were found. The magnitudes of the results found show the potential of applying this strategy in an arid climate.
