Abstract

Electrochromic glass is part of the active dynamic glazing: it is able to reversibly modify its optical features (colour and transparency) according to a preset parameter or on direct command by user. The change occurs applying a weak voltage to a multilayer film in which a red-ox reaction is induced. Panes are usually applied on not opening frames and they normally work in the ON state during the high sunshine daylight hours. We revealed the need to partially or fully open the windows for long or short time, both in the OFF and, in special cases, ON state. In these specific cases the electrical signal must be rightly transferred trough movable contacts. Contacts must be able to efficiently transfer the electrical signal which is characterized by quite low voltage. They must have a good resistance to wear and weathering and also be acceptable from the perceptual point of view. The DICAAR and DIEE have ongoing trials with the objective to propose integrated solutions, such as the hinge-contact system, which enable both the opening of diversified types of window that the transfer of power signals.
