Sunphade: Dynamic solar control film for windows
- Published 17 March 2025; updated 23 March 2026; estimated reading time 3 minutes. Marked available in Europe, but produced in batches and must be preordered. Listed under Architecture and construction and Smart cities.
- Sunphade’s photochromic nanoscale film is applied to the outside of windows. It darkens as sunlight intensifies and clears as it fades, with a stated visible-light transmittance range of 45–85%. The company says the film blocks up to 66% of solar energy, reducing cooling demand while retaining daylight and views; these performance figures are article claims.
- The page presents the film as an alternative to blinds and screens, with no routine maintenance and simpler production than other solar-control technologies. It says the product can improve indoor comfort and reduce building energy use, but gives no measured energy-saving data or building-specific results in the article.
- The article says Sunphade signed 10 paid pilot agreements with Norwegian property stakeholders in 2023 and produced and sold 1,500 m² for client-site installations in 2024. It says initial target customers are large commercial/public buildings in the EU, with planned US expansion. Case-study links are provided for Oslo University Hospital (Rikshospitalet) and the University of Oslo.
- Market estimates cited include more than 2.3 billion buildings globally, solar-control window film reaching nearly USD 1.3 billion by 2030, and solar-control glass reaching USD 10 billion by 2033. These are attributed third-party forecasts.
- Linked to SDGs 7 (Affordable and clean energy), 9 (Industry, innovation and infrastructure) and 11 (Sustainable cities and communities).
