Bloomberg HQ London

  • Financial media giant, office space with ground floor retail

3.2 acres

Bloomberg’s European headquarters is located in the heart of the City of London, close to the Bank of England and St. Paul’s Cathedral. It is a beautiful illustration of sustainable development, boasting a BREEAM Outstanding rating, and the highest design-stage score ever achieved by any major office development. In 2018, Bloomberg was awarded the Stirling Prize.

Simmtronic worked closely with building services consultant Grontmij (now Sweco) early on in the project design. Lighting control components were carefully chosen to provide the client with a lighting system in their building which met their needs.

Early on in the project Simmtronic supplied and commissioned lighting control equipment to a mock-up of a floor area in Germany. This enabled the client to see how the lighting and lighting controls would work and make adjustments if required. Another benefit of carrying out a mock-up was that the construction team could use this as a lesson learnt exercise which helped when the same areas on site were constructed for real.

The lighting panels in the open plan office were programmed in a “petal” sequence, which means the central panel above a person would be on fully illuminated, then the surrounding panels would be dimmed. This provides the user with sufficient light to work effectively, but also reduces the lighting energy usage in the surrounding areas.

As the building is used around the clock, occupants found that sometimes they might be the only person left working on a floor outside of normal office hours. The users noticed that luminaires had dimmed down and turned off where there was no occupancy in the surrounding areas. So, the control of the lighting panels was re-programmed to dim down to a low level but not switch off at night, to provide the user on that floor some comfort of not being surrounded by darkness. With such large floors and the lighting originally dimmed to off, the users found this uncomfortable not to be able to see their surroundings.

The presence detectors in the office areas were sprayed with special paint finish to compliment the uniquely designed ceiling so they seamlessly blended in.

The control and operation of back of house areas such as plantrooms were subject to discussion and review. The client decided the lighting would be switched on at full level via a local wall switch, then if the lights had not been manually switched off after a time period of two hours, the lights would all dim to 50% output, so as to alert the user the lights would be turning off shortly. This automatic operation ensured the user had sufficient light to work safely, but the lights would not be left on unnecessarily.

The client wanted a lighting control system which they could maintain and operate themselves once the project was installed and commissioned.

The Simmtronic lighting control system uses:

  • an easy-to-use head end with clear software graphics enabling maintenance
  • interrogation and fault status reporting of luminaires
  • changes/adjustments to be made as the building’s usage evolves
  • interfacing to other building services systems such as the BMS, AV and security systems.

Thank you Simmtronic, for your professional, fast and reactive support with the delivery of these projects.

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.

Landsec have consistently used Simmtronic Lighting Control Systems across our new London developments for over 15 years. Simmtronic understand our requirements and get involved at the very early stages of schemes, assisting consultants in achieving the optimum design solution, often taking the lead.  They always overcome the programme challenges they are faced with on site, delivering a quality, fully tested and operational solution, on time and to budget. Simmtronic undertake the maintenance and servicing across much of our London portfolio, they have a customer focused and flexible approach that suits the needs of our business and as well as our customers.

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.
