Tower 42 celebrates an LED first

Tower 42, the prestigious City of London office building, has completed a major investment and refurbishment of its Level 12 office space, introducing specially customised solid state Savio remote phosphor LED light fittings and advanced Light Master Modular lighting controls from Philips Lighting. This is believed to be the first office space in the UK to use all solid state lighting, achieving a significant energy saving of around 40% compared to a conventional T5 fluorescent installation.

Tower 42 has taken the opportunity to introduce energy performance features and reduce carbon footprint through this extensive investment on Level 12, relating to c. 9,000sq ft of office space.

“We are committed to minimising our environmental impact, while maintaining the quality and high standard of the office facilities we provide. Prospective customers are also looking at energy performance more closely,” explained Tower 42’s Building Services Manager John Gentry. “Consequently, we evaluated a number of options for the lighting on Level 12 and the combination of LED lighting and controls proposed by Philips offered the best overall energy performance and life cycle costs.”

In tailoring the lighting solution to the space, Philips Lighting worked closely with Tower 42 and managing agents BNP Paribas Real Estate to arrive at a solution that would address commercial, aesthetic and environmental imperatives, while taking into consideration the needs and requirements of potential office end-users, Tower 42’s customers.

“Philips created a mock-up of the proposed fittings in the space and we invited comment from a number of stakeholders. They proved to be very adaptable and responsive to the feedback and this led to the production of a customised version of the Savio fitting,” John Gentry recalled.

The popular 600mm x 600mm Savio fittings, originally developed for use with fluorescent light sources, were adapted and optimised for use with 3 x 18W Fortimo LED light sources to create an edge-to-edge lighting appearance with a uniform and comfortable surface of light.

Savio luminaires feature a patented micro-lens optic to ensure optimum light distribution and full glare control, compliant with the highest standards for office lighting. The evenness of the lighting is further enhanced by the innovative design of the Fortimo light source, which uses a combination of high efficiency blue LEDs with a separate phosphor plate to generate a bright white light with an efficiency of 62lm/W.

All of the lighting is controlled through a Philips Light Master Modular (LMM) lighting management system using DALI (digital addressable lighting interface) protocol so that all luminaires are individually addressable. Multi-sensors are used in the spaces to provide both dimming in relation to daylight levels and occupancy detection with corridor linking. Occupants will also have the ability to control their own lighting using infra-red remote control units.
