  • Tunable white lighting throughout creates lighting conditions to suit a large variety of client needs, moods, perceptions and psychological well-being. The benefits of tunable white lighting include: the ability to control a light source’s colour temperature output using a remote control or external control system and enabling the selection of the desired colour of white – courtesy of warm and cool tones – which imitate the part of the circadian rhythm responsible for stimulating and maximising productivity
  • The Broadcasting Studio on Level 5 enjoys certain lines of sight, showcasing notable city landmarks in the background behind the circular glass studio and is complimented by colour temperature control, different atmospheres can be created
  • The huge spiralling, bronze-encased 200m-long walkway is a hybrid of stair and ramp, following a shape called a hypotrochoid. The staircase incorporates three types of LED lighting displayed via the: handrail, foot-treads and underneath the stairs – all DALI dimmable
  • The entrance area to the viewing gallery of the Roman ruins is encased with dimmable LED lighting


  • Named the Winner of the Stirling Prize 2018 for the UK’s best new building, this ambitious £1bn project was built solely for one client
  • Rated the world’s most sustainable office building, Bloomberg London HQ saves 73% in water consumption and 35% in energy consumption and CO₂ emissions
  • Metal ceilings hold 2.5 million polished aluminium petals that serve as light reflectors. 500,000 LED lights were incorporated into the ceiling – they use 40% less energy than a typical office lighting system
  • The building achieved the highest design-stage score ever achieved by any major office development in the world – 98.5%
  • The building matches the height of its neighbours because owner, Michael Bloomberg, wanted to be a good neighbour and not build higher than the surrounding buildings
  • Taking a decade to build, the new European Headquarter has been designed to push boundaries, aid teamwork, propel innovation and assemble Bloomberg’s 4,000 London-based employees under one roof
  • Staff work at bespoke sit-stand desks, up to 700 people to a floor
  • The building is constructed on the site of the Roman temple of Mithras
  • Archaeologists from MOLA’s excavation discovery found 400 timber writing tablets; the first known reference to London and the earliest hand-written document in Britain. Some of the 14,000 artefacts are now on public display in the building’s London Mithraeum basement

Simmtronic have delivered a large number of technically challenging projects for DBS and consistently continued to provide outstanding service. Their support, guidance and help throughout the process has been exceptional, working closely with our design teams to ensure the right solution for the project and a sound understanding of the brief, with our delivery teams to ensure the installation and commissioning are trouble free and then providing fantastic after care to the customer. They have added true engineered value into the projects they have been involved in for Derry Building Services.

Over the years I have really appreciated the Simmtronic ability to provide responsive support and listening to projects and clients needs. More recently the Simmtronic team has shown the capability to embrace the connectivity requirements of the Internet of Things by quickly adding MQTT to their range of integration protocols. This will greatly facilitate telemetry applications in buildings and the development of interconnected solutions that will make buildings more usable and easier to operate.

Simmtronic as an organisation has been, for the last 18 years, by far the best performing and most reliable lighting control system I use. From design through to commissioning and soft landings with the landlord teams Simmtronic always deliver on my projects. Simmtronic technology evolution is not just pushed through like others, but rather properly tested internally first, giving us as client teams the assurance that what Simmtronic say they can offer is 100% delivered, an absolute must with fast track major projects.

Simmtronic has constantly been available at an early stage to engage both with the designers and the Contracting team to assist with design solutions and to test options. This ultimately assists us in de-risking the project during the commissioning phase which usually defines when the project is completed. Simmtronic is seen as ‘industry standard’ and it is always encouraging to see them involved.
