| Abstract |
The application of all-glass smart double skin envelopes requires accurate models for the simulation of their performance. In order to develop this model, a simple “minimalistic” lumped model is postulated and then calibrated with a parameter estimation technique based on in situ monitoring of a full-scale element. The approach is contrary to similar work that attempts to derive the behavior from detailed modeling of the physical transport phenomena. It is found that the calibration model is surprisingly accurate and ideally suited for use in the ensuing optimal control and performance studies. Based on the comparison between the simulation models of two different systems, it is concluded that the simulation model of double skins should be calibrated depending on the system's configuration (height, width, cavity, glazing, louver, etc.) and local surroundings since no universally applicable simulation model exists at this moment in time. This leads to the next challenge of developing an on-line self-calibration technique. |
