Electrochromic glass: behaviour and energy saving

The research group, from several years, dealing with Electrochromic Glass and their performance in the energy field. As already introduced in the presentation of the GPD 2011, the research, started with simulations using specific software, is at present, to being tested on real physical models. Two test rooms have been made perfectly identical as regards orientation, dimensions, materials, elements and construction system: in the first room EC glass were laid, in the second one Low-E glazing of equal size. In this phase, which began in January and will end in December 2012, at fixed times, the EC glazing go from OFF to ON condition. In both test rooms survey tools detect, at predetermined time, the most important indoor thermo physical parameters such as: temperature, air humidity and solar radiation. The data are recorded, processed and displayed in graphs showing the internal conditions related to outside parameters. The objective of this step is to compare, in both rooms, the internal conditions of temperature and solar radiation to reach calculate consumption and energy costs required to achieve same indoor condition. In the second phase, will study the thermal energy performance as a function of envelope variants. Most of all it‘ll be studied that one relating to the different relationship between glass and opaque surface.
