The U.S. Department of Energy's Solar Decathlon challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. The winner of the competition is the team that best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency

The winner of the 2015 USDE Solar Decathlon was Stevens Institute of Technology, whose team created the sustainable and resilient 'SURE House'. The vision behind SURE House was to provide protection from extreme climates while embracing the coastal home aesthetic. SURE House marries the most advanced technologies and modern features with a nature-centric design philosophy, blurring the lines between interior and exterior spaces wherever possible. The integration of Natural Light was vital for the realization of SURE House, and the team chose Ketra lighting and controls for a fully immersive Natural Light experience.


Throughout the home, Ketra products illuminate key spaces that are both blended with light from windows (kitchen) or relying solely upon artificial light (bath). In choosing a lighting solution, project lead Christopher Steffens of the Schaefer School of Engineering and Science took into consideration Ketra’s ability to mimic sunlight. “We wanted a daylight feel in the windowless bathroom,” says Steffans. “And when the jury toured the house, we showed them our ability to create Natural Light throughout.”

With exceptional energy-saving capabilities, a streamlined, versatile controls solution, and the aesthetic superiority of Natural Light, Ketra was instrumental in the 2015 Solar Decathlon win, and is honored to illuminate SURE House.
