Novel glazing technology for building envelopes

Evaluation of the energy performance and its influence on thermal control

Master project Sara Vanzo, Politecnico di Torino, 2015

Glazing technology could play an important role in improving energy efficiency of buildings from the point of view of thermal control as windows usually account for about 30% – 50% of transmission losses through building envelopes. The aim of this master project was to study a set of different building design cases, discussing different innovative glazing technologies installed and their influence on thermal control with a view to reducing energy consumption.

A general overview of the state of the art in the field of the novel glazing technology for building envelopes was presented. The initial part consisted in the optical characterisation of some glazing samples, such as insulated glass units (IGU) and Grätzel cell modules, in order to obtain the energetic performance of these different glazing envelopes. Secondly another particular solution for the improvement of the performance of the glazed façades was widely discussed, which involved an innovative typology of complex fenestration systems: embedded microstructures for glazing envelopes. In this second part of the master project a parametric study was performed, to characterize this type of technology in terms of thermal control.
