Energy Saving and Indoor Comfort Features in Residential Buildings Using Electro-chromic Windows

摘要

The need to optimize the energetic performances of buildings without compromising indoor comfort conditions has induced in the past few years a technological improvement of material typologies used in the building industry.Particular attention,indeed,was dedicated by researchers to transparent materials with the aim of improving the energetic and optical performances of windows through an optimal utilization of solar radiation.In this context,the present work analyzes the behaviour of electro-chromic windows with respect to their visual and energetic performances shown in two typical Italian climates.For two Italian cities the influence of the glasses on energy savings and indoor visual conditions has been investigated and compared with the performances of a simple double panel windows.In addition,an analysis of the influence of window surface on energetic and visual features has been carried out.
