Implementation of Hybrid Ventilation Technique in Double Skin Facade Case study: Office Buildings in Egypt

Abstract

ABSTRACT The great interest of the double skin facade (DSF) innovation has been increasing worldwide. Despite its advantages and positivity that have been studied and focused on through the past years, as the main force of the naturally ventilated double glazed office buildings implemented in hot arid climates system is provided by the natural ventilation sources. DSF layers can be overheated during summer due to the coincidence of high outside temperatures, solar gains and internal heat gains. Although DSF system were originally constructed to deal passively with this climate conditions, now DSF buildings are plagued with air conditioning units resulting a more energy consumption that needed for maintaining acceptable internal thermal comfort limits.
