Theme B: Creating a livable, healthy and environmentally viable citiesT-type thermocouples. The wind velocity in the cavity was measured using a hotsphereflow meter (TESTO) and pressure difference between indoor and outdoorwas measured using a pressure transmitter. T-type thermocouples were installed atthree points vertically as shown in Fig 2 to measure glazing surface, cavity air andindoor temperatures. The data was collected using a National Instrument datalogger.

MATHEMATICAL MODELIn order to describe the dynamics of the double skin systems solvable withreasonable efforts, a space-averaged lumped physical model with six statevariables was introduced according to (Fig. 3). The state variables represent thespace-averaged temperatures in the horizontal and vertical direction of eachglazing of the exterior double pane, the cavity air within the double pane glass, thelarger cavity air, the louver slats, and the interior glazing. Although this approach499
