How to light the City’s tallest building

A UNIQUE luminaire has been developed for the City of London’s tallest skyscraper, 22 Bishopsgate.

Developed by Future Designs in conjunction with HDR | Hurley Palmer Flatt and 22 Bishopsgate's architects PLP, the Glos fixture was also specially designed to be fast and easy to install to meet the fast-track nature of the project

The linear recessed light fitting, designed to mesh with the building emphasis on the wellbeing of its occupants, delivers 157 lumens per watt and handles 45 litres of air every second.

Developed by Future Designs in conjunction with HDR | Hurley Palmer Flatt and 22 Bishopsgate's architects PLP, the Glos fixture was also specially designed to be fast and easy to install to meet the fast-track nature of the project, which was managed by AXA IM – Real Assets on behalf of an international consortium of investors, with Lipton Rogers Developments retained as developer.

The luminaire has been installed in all 130,000 square metre of office space in the 288 metre tall tower.

The air handling testing was carried out by BSRIA, an independent research consultancy that provides specialist services in construction and building services.

The test confirmed an air handling requirement of 45 litres per second through air slot apertures designed for the maximum pressure drop of 5Pa.

22 Bishopsgate is set to be Europe's first ‘vertical village’, with wellness and its impact on productivity of workers is a high priority for the design of this office building.

It features London's largest cycle park and a state-of-the-art gym, complete with a climbing window, 125 metres above the ground on level 25, as well as a wellbeing retreat on level 41.

The developer has recently applied for the Delos WELL Building Standard.

The building is a complex, 22 sided, faceted glass structure.

The design is built and managed to satisfy the changing nature of the City of London in terms of the type, size and priorities of companies based there, including demands for high standards of technology and sustainability.

According to the statistics from the City of London Corporation*, while just over a third of businesses were financial services, tech was the fastest growing major sector in the City with jobs growth of 16 per cent, the quality of workspace needed to reflect that in order to attract a more diverse range of tenants.

Emphasis has been placed on constructing a building with flexible floorplates, high ceilings and lighting that complements the natural light flow, which is enabled with three metres high, triple glazed windows.

The creation of approximately 9,300 square metres of social spaces and services throughout the floors was a key part of the design.

There is a2,043 square metres of food and dining space on level 2, a members' club on level 57 and London's highest public viewing gallery on level 58.

Recognising the little-known fact that 99 per cent of City businesses are SMEs, there is an innovation hub for small businesses and start ups on level seven.

Levels three and four, meanwhile, will house a new 4,738 square metre events and meeting venue available for use by the hour or day.

As well as providing a place for 12,000 people to work, creating a diverse business community, 22 Bishopsgate also provides a range of retail, bar and restaurant units.
