Eyrise glass transforms Grade II-listed rooftop

Eyrise dynamic solar shading glass has transformed a Grade II-listed London building’s new rooftop dome.

The Royal United Services Institute (RUSI), an independent security and defence think tank, worked with bespoke structure design and build company, Octatube, and solar glazing specialist, Eyrise, to modernise the architecture of its historic headquarters at 61 Whitehall, as part of a wider renovation to improve the building’s office facilities.

The glass half-dome structure is situated on the original roof terrace, creating additional indoor space for RUSI. It serves as a meeting and events hub.

“Our new dome really modernises the building and offers sweeping views over Whitehall,” said Jonathan Eyal, associate director of RUSI. “The space is key to our organisation’s ability to bring people together in the heart of London to progress and influence conversations around global security and stability.”

The stainless-steel frame, built by Octatube, consists of 15 custom-made curved beams connected with horizontal transoms and measures 12.5m wide by 4m high. It features 70 Eyrise s350 double-glass panels covering 85m² that can be individually adjusted from bright to dark states. Liquid crystal technology instantly reduces solar glare and helps to maintain a comfortable temperature.

RUSI can automatically or manually adjust single panels, groups or the entire array to create an optimum environment, which in turn reduces the need for heating and air conditioning.

“The use of Eyrise dynamic glass at 61 Whitehall, which was originally built in 1896, demonstrates how advanced facade technology can blend historic and modern aesthetics to create sustainable, beautiful architecture,” said Dr Michael Grund, CEO of Eyrise. “Our commitment to pioneering smart building solutions is shaping the future of healthy construction.”

RUSI is reported to be the world’s oldest independent security and defence think-tank, founded in 1831 by the Duke of Wellington. A British institution operating with an international perspective, it produces research and events focused on UK defence, security and global affairs.
