High power consumption cooling devices such as air conditioners increase electricity power demands. In this project, an alternative solar-powered cooling system is suggested to reduce the air temperature to human comfort level and reduce their household electricity usage. Plants are used in this project to undergo transpiration, which is a natural process where moisture is carried from the roots to the underside of the leave to be evaporated. Heron’s fountain technique was applied to reduce the power consumption of the water pump by lifting up water using gravity. Power consumption is reduced to 23 watts per hour and the air temperature around 1 °C to 2 °C of a 90 square feet single bedroom depending on the surrounding condition. This gives human a range of thermal comfort of 25 °C to 29 °C in residential buildings.
