In hot and arid climates, evaporative cooling appears to have significant potential to provide thermal comfort and reduce the energy loads of summer season. These regions used wind towers as means to reduce energy consumption of air conditioning systems.However, the cooling potential of wind towers techniquewas investigated in real exiting building in Ouarglacity of Algeria (hot and arid climate); Measurements have been performed under two conditions with and without evaporative potential.A mathematical model of wind tower has been developed and validated using the measured data. For a more effectiveevaporative cooling, a number of improvements on wind tower design was proposed and calculated.Hence, results showed better performance with the improvements.However the new design of the wind tower are constructedin another building under the same climatic condition, the results of monitoring the performance of the building incorporating the new design are discussed in this study.
