With its innovative power-generating windows, the start-up PHYSEE from Delft won the grand prize of €500,000 in the Postcode Lottery Green Challenge in 2016. This month, these fully-operating PowerWindows will be installed for the first time in the sustainably-built office of Dutch Charity Lotteries (Postcode Loterij, VriendenLoterij, BankGiro Loterij) in Amsterdam-South. By mid-2018, there will be workstations for around 600 employees who will be able to charge their electrical devices with power generated by the PowerWindows.

Ferdinand Grapperhaus, PHYSEE's CEO: "Winning the Postcode Lottery Green Challenge has given our company a huge boost since last year. I'm really excited that the Lotteries have now dared to take the brave step of installing PowerWindows in their new, sustainable offices. This is a tremendous showcase for us, which we will use to break into Amsterdam's real estate market! We hope this will lead to a breakthrough and that plenty of other companies will follow suit."

Esther Wubben, Project Leader Renovation New Office Dutch Charity Lotteries: "In line with our mission, it’s our ambition to achieve one of the most sustainably-converted office in the Netherlands. In addition to more established sustainable applications, such as solar panels, we also wanted to give innovations like PowerWindows a role in our new building. Like ordinary windows, they’re completely transparent, so you hardly notice any difference. These PowerWindows will be installed on the south-facing wall shortly. Hopefully, we’ll also inspire other companies to make the move towards power-generating windows!"
