Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned. Therefore more and more of these buildings are being built with doubleskin facades, which can provide: a thermal buffer zone, energy savings, wind protection with openwindows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, pollutantprotection with open windows, nocturnal cooling and a site for incorporation of PV cells.
Double skin facades have become a major architectural element in office buildings over the last 15years. A double skin facade can provide a thermal buffer zone, solar preheating of ventilation air,energy savings, sound protection, wind and pollutant protection with open windows and nocturnalcooling. Commercial buildings with integrated double skin facade can be very energy efficientbuildings with all the good qualities listed above.However not all double skin facades built in the last years perform well.
