Buildings are major users of electrical energy which consume about 75% of the total electricity generated [1], and the design of energy efficient buildings are of high priority for energy conservation. As air-conditioning accounts for about 73% of the electricity consumed in residential buildings in hot and arid regions [2], in order to conserve electricity, building systems efficient in energy conservation should be developed.
