It was inspired from the common air-conditioning unit installed on almost all building facades in the contemporary cities[1]. According to the latest research results every 9.000 BTU air-conditioning unit produces about 10L/day of distilled water[1]. Moreover bigger units on public buildings produce 40L/100m2. Furthermore a 9.000 BTU unit expels in the atmosphere 800gr CO2[2]. This project proposes an alternative use of these useless outputs in order to benefit from them. More specifically, the water produced by the unit is used to grow vertical gardens in cities, which will contribute to a more purified environment, whereas the unit collects an amount of solar energy and converts it to electrical energy.http://creativecommons.org/licenses/by/4.0/ 745 - 75013th SGEM Geoconference on Nano, Bio and Green – Technologies for a Sustainable Future Ouggrinis Konstantinos-Alketas Ουγγρινης Κωνσταντινος-Αλκετας Paterakis Iason Πατερακης Ιασων Vidalis Dimitrios Βιδαλης Δημητριος Voradaki Georgia Βοραδακη Γεωργια Tralo Alma Τραλο Αλμα Dimopoulou M.
