These Shadow-Free Skyscrapers Reflect Daylight Into Cities

No more dark and gloomy financial districts.

Our modern obsession with packing into cities means that increasingly massive skyscrapers are inevitable. After all, if we don’t head upwards, well, there’s only so much land.

One of the problems with skyscrapers, though, is that their behemoth shadows seriously shorten the day of their surroundings. Even a spacious, sunny city like Sydney can feel cold and dark when you’re wedged between towers (just look at the long shadow Barangaroo's casino is expected to cast). Now imagine how gloomy things can get in densely populated metropolises like London and New York — if you've visited, you'll know how gloomy things can get in the financial districts.

But a London-based architecture company by the name of NBBJ has come up with a solution: the 'No Shadow Tower'. The concept involves two twisting skyscrapers, to be built side-by-side, which redirect sunlight to the area around their base — right where dreary shadows are usually found lurking. The idea was developed with London’s North Greenwich in mind, at the request of New London Architecture, and was first published in New London Quarterly.

"The algorithm design for the tower is based on the law of reflection," the design team told Dezeen. "Our facade has varying angles of panels that distribute light over a certain area at multiple times during the day."

The algorithm works by recording the sunlight's angle every single day for an entire year. With this information, the team can predict how light will play on the building at various points during the day, and then construct the skyscraper’s facade to reflect it accordingly. The use of individual panels allows reflection on a pane-by-pane basis; creating circles of light, rather than a single, extremely hot area.

NBBJ was motivated by its passion for the public and their environment-determined happiness. "One of [our] principle concerns is public space and the ways the public use and interact with these spaces," the designers explained. "The No Shadow Tower places public space at the heart of the project, along with human interaction and the impact of skyscrapers at street level... The research that we have undertaken could be applied in many locations in the world, each time creating a different form that would relate to its specific context and solar conditions."
