I dette prosjektet har Sunphade videreutviklet sin glass-film slik at den kan brukes i flere vindusprodukter. Målet var å kommersialisere en teknologi som muliggjør at vinduer går fra helt gjennomsiktige til mørke kun ved hjelp av sollyset. Sunphade sin teknologi er fortsatt i en tidlig fase og det er viktig å tilpasse glass-filmen til behovene til de store glass- og vindusprodusentene for å utvikle relevante partnerskap. Prøver har vært til uttesting hos en fremtidig partner. Filmens gulfarge har gjennom prosjektet blitt redusert og dermed har teknologiens attraktivitet økt. Dette var et av målene i prosjektet. Sunphade-filmen plasseres typisk på innsiden av et isolerglass, men tiden den brukte fra lys tilstand til mørk og tilbake var noe lang. Denne er nå redusert. Ved å redusere denne blir produksjonen av vinduene enklere hvilket er en viktig faktor når ny teknologi skal introduseres i vindusbransjen.

The outcome for Sunphade has be increased competency and the possibility to use this momentum placing products for window glass in the market. The TRL level will be increased further through a close cooperation with the glass producers as well as window film producers. IFE has been abe to strenghten its position as the leader in photochromic research. For more than11 years IFE has been working on smart windows and materials development for smart windows as well as ab initio modelling. The value creation for Sunphade given the product improvement is high and has the potential to impact the window industry as a whole. The window industry will soon have solar control products for the mass market, that are commercial attractive, meet the demands from the market drivers and reduce energy consumption in buildings. Sunphade will become one important technology for CO2 emission reduction.

Sunphade is improving the comfort of offices by letting the right amount of sun into the office space without compromising the outdoor view. Sunphade is a photochromic film switching from clear to dark depending on the amount of sun. Sunphade removes glare, reduce the need for blinds and energy demand for cooling. This is a win-win for employees, employers, office owners and the environment all over the world. Sunphade is applied to glass with industrial sputtering, a well-know industrial coating process for both metals and other inorganic compounds. Sputtering equipment is present at most production lines for glass and has been used industrially for decades. The Sunphade technology will therefore due to its low material input and high output, reach a competitive price level. Sunphade is now preparing the first generation of its photochromic film for glass for the first potential industrial partners. The film is applied onto glass and placed within the space of an isolation glass unit (IGU). The Sunphade film is currently a niche product due to the switching time from dark to clear state. Additionally it is inherently yellow, a property we want to reduce in order to make it more attractive to a lager market. The next version of Sunphade will solve these issues. When solved, Sunphade will have a massive market impact due to the fact that it can be implemented in any standard IGU production line without modifications and at a low material cost. This application is therefor about making to the next version of Sunphade with boosted photochromic response on isolation glass units.
