Description Direct evaporative cooling relies on latent heat absorbed during water evaporation to cool down the environment. It has being used for thousands of years in vernacular architecture in hot dry climates. Nevertheless, it is still regarded as an unusual cooling solution in modern buildings when compared to heat pumps. This project builds upon recent experimental research on this field (downdraught evaporative cooling) to assess potential energy savings related to the use of this technology. Key Objectives Calculate potential savings due to the use of direct evaporative in downdraught cooling towers in several locations across the globe. Identify critical barriers to the implementation of such solution. Identify possible mitigation measures to minimize negative impacts of this solution. Design a compact system using this solution
