Electrochromic glass \u2013 which instantly glazes or shades at the flick of an electrical switch \u2013 has proved popular in a range of applications where the control of light and heat is important. But the physical nature of the glass and the costs involved limit the opportunities open to this technology. An EU-funded project has applied these ‘smart glass’ principles to a flexible film which opens up a whole new world of green, low-cost and commercially viable possibilities.<\/strong><\/p>\n\n\n\n
The process allows for varying levels of light penetration, providing a choice of shades rather than clear and blacked-out. Electrochromic glass does not require a constant stream of electricity. Once the initial tint has been achieved, no more power is needed.
Today, the technology is used predominately to control the amount of light and heat transmission in buildings and can be applied to reduce heating and air-conditioning costs as well as increasing comfort by reducing glare.
The technology behind electrochromic glass holds great potential for commercial applications although the production process and the weight of the actual glass can limit its application. With this in mind, the EU-funded Innoshade project set out to produce alternative, low-cost electrochromic shading technology which would be cheaper to produce and provide more opportunities for commercial applications while delivering lower energy consumption and faster response times. The project targeted the development of products in three specific areas with commercial appeal: ophthalmic lenses, domestic appliances, and aircraft and vehicle applications.
\u201cWhile upscaling EC technology has been done before, this is only true for glass windows employing expensive \u2018sputter technology\u2019 (depositing electrochromic and ion-storage layers in vacuo over large areas),\u201d says Dr Uwe Posset, the project coordinator at the Fraunhofer ISC\u2019s Centre for Applied Electrochemistry in Wuerzburg, Germany. \u201cInnoshade has developed mechanically flexible, low-cost EC films that could be put on to any surface and used in applications where glass windows are not viable for weight reasons, such as in aircraft.\u201d
Environmental benefits<\/strong>
The project team developed the film with additional environmental benefits and sustainable development properties in mind, such as reduced mounting space and weight, reduction of heat loss in appliances, and retrofitting.
\u201cAccording to our life-cycle assessment studies, there is considerable energy-saving potential in a number of applications,\u201d says Dr Posset. \u201cWe have seen verifiable savings of energy needed for air-conditioning in vehicles; there is no need for mechanical shades in aircraft cabins which leads to high weight savings compared to glass-based smart windows, while increasing comfort for the passengers at the same time; and we\u2019ve recorded substantial reduction of heat loss and heat penetration in appliances.\u201d
The resulting EC film developed by the project represents a breakthrough in smart-shading technology by overcoming common limitations of state-of-the-art electrochromic devices. The film allows for retrofitting (not possible with previous technologies); it provides lightweight, flexible and impact resistant EC films in contrast to traditional heavy, rigid and fragile EC glass elements; and the costs involved are anticipated to be reduced \u2013 \u20ac200\/m2 for dimmable film compared to \u20ac1000\/m2 for conventional smart-window technology. Pilot lines for the production of the films have been put in place and are ready to be used in follow-up activities.
Innoshade\u2019s strong links with industrial partners \u2013 the project consortium includes five small and medium-sized enterprises and four multinational global players \u2013 is expected to prove invaluable when the technology moves from the laboratory to the market place in the future.
This innovation was made possible by Israel\u2019s continued participation in the official Horizon 2020 fund, managed in Israel by ISERD part of The Israel Innovation Authority (Formerly the Office of the Chief Scientist and MATIMOP). The initiative has taken Israeli R&D to the next level with the help of ground-breaking collaboration between scientists in Israel and Europe, as well as essential funding and support.<\/p>\n\n\n\n
