Comparative analysis of selected glass systems by dynamic simulation using measured real environmental conditions

Abstract

The subject of the study presents the measurement of temperatures on surfaces of glass systems of existing structures and the surfaces of experimental glass systems obtained by dynamic simulation. Measurements were made in the test cells of the Faculty of Civil Engineering of the Technical University of Košice. The partial results of which are the basis for the comparison of the currently installed and experimentally designed glass systems using spectrally selective films. The proposed mathematical-physical model was simplified by replacing the sash, frame and its components with a homogenous element with minimal shape modifications, while this does not have a significant effect on the simulation results. The choice of the proposed glass system respects the need for reduction of solar gains in summer and heat losses in buildings in winter through the weakest part of the building envelope and indicates future energy savings in relation to cooling and heating costs with a view to optimizing light and thermal comfort.
