THERMAL PERFORMANCE EVALUATION OF VENTILATED FAÇADE THROUGH CFD MODELLING IN REDUCING THE COOLING LOAD OF A CLOSED ROOM IN HOT AND DRY REGION

Reducing energy consumption due to cooling load will have a significant positive impact on the economic growth of hot/warm countries, the majority of which are developing / underdeveloped, as well as on global warming effects. One of the most effective ways in reducing the cooling loads on the buildings is the use of Facades, but it has not been thoroughly investigated. In this paper, numerical analysis of the effects of installing thin opaque ventilated facades on the side walls of a closed room on its cooling load have been analysed. For moderate climatic conditions, the different façade configurations (covering all four sidewalls) with two different air cavity gaps (2 inches and 5 inches) have been studied. It has been observed that using facades can reduce cooling load by approximately 18.8601% when it was used on all side walls compared to that of without facade.
