With rising heat waves and climate change, the big cities are meshing up with the buildings woven in urban fabric that are becoming power-guzzling air-conditioning machines that increase energy demand multi-fold. This has the side effect of heating up the environment because the return heat from air conditioners mixes with the surrounding air. This dents the microclimate and makes the micro and macro systems worse, as this process is continuous without break. So it will be a disaster for the environment in the future. To mitigate the problem, the paper borrows traditional wisdom to merge with smart technology and create comfortable built spaces in hot-dry and hot-humid weather conditions, based on the principles of evaporative cooling, the venturi effect, and the faraday law of electromagnetic induction. The output of adopting these principles creates comfort conditions for air ventilation with improved air quality and a natural air-conditioning system, ensuring the luxury of contact-free cool air in habitable spaces. The process is based on interoperability, which is built into the system to self-generate and consume renewable energy. The integration of information into the system is a spontaneous cycle of production and consumption of energy. This ensures its self-sufficiency, which bridges the research gap in the design of an upgraded passive downdraft cooling system with three self-sufficient and effective benefits in a single system.
