Vertical greening systems (VGSs), i.e., living walls (LWs) and green façades (GFs), are considered a promising technology to diminish the negative effects of urbanisation. Plant selection for these systems is challenging due to the narrow spectrum of species available, and the required adaptation to specific climate conditions. Considering Chile’s rich plant biodiversity, this study aims to analyse the potential of Chilean native species to be introduced in VGSs. A total of 109 potentially usable species from the north (n = 25), centre (n = 32), south (n = 31) and the Andes Mountains (n = 21) were selected for VGSs, showing a high level of endemism (43.1%). According to the filters applied, 39 and 70 species were selected for GFs and LWs, respectively. To evaluate appreciation of Chilean native plants and their potential use in VGSs, an online questionnaire was responded by 428 individuals. Most participants agreed or strongly agreed with the use of LWs and/or GFs inside their house/apartment (75.5%) and in their garden/balcony (90.0%). Most of the participants agreed or strongly agreed with the use of Chilean native plants inside their house/apartment (75.0%) and in their garden/balcony (84.4%). Further empirical studies are still required to confirm the use of Chilean native species in LWs and GFs.
Resumen: Los Jardines Verticales son un sistema de enverdecimiento de paredes y muros tanto en el exterior como en el interior de edificios. En este último caso se requiere de un sistema de iluminación artificial para asegurar un desarrollo correcto de la vegetación. El objetivo de este trabajo es analizar el efecto de tres luminarias LED comerciales en la iluminación de jardines verticales interiores en términos de calidad visual y correcto desarrollo de las plantas. Las luminarias testadas se diferencian en la potencia y tipo de luz. Los resultados obtenidos muestran que las tres luminarias son aptas en el desarrollo de las plantas, pero la luminaria de luz rojo/azul (tipo C) presentó en general un menor crecimiento en las plantas, menos cobertura del jardín y daba una apariencia poco natural a las plantas debido a la mezcla de rojos y azules. En relación al consumo de agua, fue un 30% superior en el caso de la luminaria de luz blanca de mayor potencia (tipo A) en referencia a las otras dos.
