Governors Island

As part of the Governors Island Climate Solutions Challenge, Sunphade has deployed its dynamic solar control film in New York City. The installation is designed to reduce solar heat gain and glare while preserving daylight and views. Early observations already indicate improved indoor conditions, with measurable reductions in both light intensity and temperature.

The Challenge

Buildings with large glass surfaces often face issues like excessive sunlight, heat gain, and glare, which can negatively impact indoor comfort and visual conditions. On Governors Island in New York City, the objective was to investigate how existing windows could offer improved solar control while maintaining natural daylight and visibility, all without the need for electricity or replacing the glass.

The Solution

As one of the winners of the Governors Island Climate Solutions Challenge, Sunphade installed its patented photochromic solar-control film in Building 108 on Governors Island. This film automatically responds to changing sunlight conditions by darkening in response to stronger sunlight, which helps reduce incoming light and solar heat gain. The technology operates passively, requiring no electricity, sensors, or user intervention.

The Result

Measurements collected between June 2 and August 31, 2026, showed a significant reduction in indoor light levels. Average illuminance was 190 lux behind Sunphade-treated windows, compared with 390 lux behind untreated windows (54% reduction).

The treated area also experienced 90% fewer hours above 1,000 lux, with just 15 hours compared with 145 hours in the untreated area. These results demonstrate Sunphade’s ability to reduce excessive daylight exposure and help create more comfortable indoor lighting conditions while maintaining access to natural light.

Ferrovial Vol. 2

Sunphade completed its second installation with Ferrovial Construction, expanding the application of its solar control film to both the warehouse and heavy machinery. The project included the installation of approximately 30–35 m² of film, improving thermal comfort, reducing glare, and enhancing operator working conditions.

Ferrovial

Ferrovial’s facility in Seseña, Spain, is highly exposed to intense sunlight, leading to heat build-up and glare indoors. Sunphade installed its photochromic solar film to dynamically adapt to changing light conditions. The solution reduces heat and glare while maintaining natural daylight. The result is a more comfortable and energy-efficient indoor environment.

Fish Me

Sunphade partnered with Fish Me Fisketorget AS, a waterfront restaurant in Bergen. Due to its prime location at the harbor, the venue is highly exposed to direct sunlight, leading to glare and heat gain that can impact both guest experience and staff comfort. To address this, Sunphade installed its dynamic, photochromic film across selected glass surfaces.

Mustad Eiendom

Sunphade collaborated with Mustad Eiendom to provide smart solar control that supports indoor comfort, sustainability, and uninterrupted views. Sunphade’s photochromic solar film was applied to the building’s glass-enclosed stairwell to ease summer heat build-up and glare, while keeping daylight levels high and preserving the Oslo fjord panorama, thus achieving the desired performance with minimal structural changes and at a lower cost than conventional shading solutions.

Rikshospitalet

Sunphade partnered with Rikshospitalet, one of Norway’s leading medical centres in Oslo, to implement our solar construction on the hospital’s windows. The collaboration aimed to enhance patient comfort, improve energy efficiency, and create a more sustainable environment within the healthcare facility.

University of Oslo

Sunphade partnered with the University of Oslo (UiO) to explore the potential of dynamic solar control. In November 2024, our solar film was installed on selected windows to improve indoor comfort, reduce energy use, and maintain clear views—without altering the building’s design.
