Resumé

The project aims at developing simplified calculation methods for the different features that influence energy demand and indoor environment behind “intelligent” glazed façades. This paper describes how to set up simplified model to calculate the thermal and solar properties (U and g value) together with comfort performance (internal surface temperature of the glazing) of a double glazing unit. Double glazing unit is defined as 1D model with nodes representing different layers of material. Several models with different number of nodes and position of these are compared and verified in order to find a simplified method which can calculate the performance as accurately as possible. The calculated performance in terms of internal surface temperature is verified with experimental data collected in a full-scale façade element test facility at Aalborg University (DK). The advantage of the simplified method is that the models are based on the standards EN 410 and EN 673 taking the thermal mass of the glazing into account. In addition, angle and spectral dependency of solar characteristic will also be considered during the calculation. Using the method, it is possible to calculate the whole year performance with different time steps, e.g. in simple energy and comfort compliance checking tools.
