Among hot humid tropical climate conditions, the common solution for climate control within working environments is the use of an active system (air conditioning). As consequence, the energy consumption, regarding cooling, increases. Therefore, the aim is to develope a sustainable cooling tool based on the integration of a biowall and a dehumidification process; thus, reducing the use of air conditioning within tropical climates in Ecuador and achieving thermal comfort. On the other hand, Living Wall Systems (LWS) are an emerging technology with a growing amount of research data revealing the positive outcomes of the system such as its ability of generating a more pleasant, healthier and productive workplace. However, it is necessary to conduct more studies about the possibilities of the LWS as potencial evaporative coolers in hot humid climates. Within this project is proposed to conduct a study on vertical gardens/living walls in order to generate thermal comfort in buildings located in hot humid tropical climates in Ecuador. The aim is to introduce dehumidification processes in order to achieve thermal comfort.Building Technology TrackArchitectural Engineering and TechnologyArchitecture and The Built Environmen
