The Department of Energy and Climate Change Practice What They Preach and Install LED Lighting

Lighting in the Department of Energy and Climate Change (D.E.C.C.) has been replaced with energy efficient, cost effective LED light sources. Since their installation, member of staff have commented on the improved brightness levels and lower energy consumption.

Prior to the upgrade, the offices at 3 Whitehall Place were illuminated by T5 fluorescent lamps. Some argue that T5 and LED lamps have the same energy saving features; building managers often opt for T5s due to their low cost. The D.E.C.C. believe a clear advantage of opting for LED light sources is their localised control system which turns lights off if rooms are vacant and dims them down to 5% as natural daylight pours in.  

During the make-over, the fluorescent lamps on all 8 floors of Whitehall Place were replaced with 1,300 Philips LED fittings.

In their own case study D.E.C.C. stated: “Compared to retrofits in most comparable buildings, which tend to use relatively inefficient T8 tubes, the energy savings are slightly lower, however they are very significant.”

The project spanned for 26 days and cost £401,000, during this time the building’s heating and cooling system was also upgraded. Since these two renovations, the energy consumption in Whitehall place has reduced by almost 30%, majority of these energy savings can be attributed to the lighting switch-over.

The D.E.C.C. anticipates annual savings of around £22,000, predicting an addition £7,000 saving on maintenance costs. They said: “There are additional savings to be had from the switch to LED lighting in the form of lower maintenance costs- it is claimed that LED luminaires typically last 5 times as long as the fluorescent equivalent.”

This refurbishment is part of the government’s recently announced UK Lighting Sector Strategy. This new initiative intends to slash energy consumption and encourage innovation in lighting.

Aside from the obvious energy and maintenance savings, the lighting overhaul has other benefits. A D.E.C.C. spokeswoman reported that responses to their questionnaire showed that, 71% of workers at Whitehall Place found that the LED light sources improved the lighting in their work space.

London Underground Upgrades To LED Lighting

Underground stations including Tottenham Court Road, Bond Street and Victoria are currently being redeveloped. Bob Benn, stations engineering manager for London Underground told the Lighting for Rail conference that once the make-overs have been complete, these stations will use 100% LED lighting
The initial lighting design was created before the LED boom, and so planned to use fluorescent lighting products. In order to keep up with the times, London Underground lighting teams have agreed to update specifications ensuring they take full advantage of newer LED technology. 

Benn said: "We were basically dealing with an obsolete design. We've managed to change it all to LED lighting, but that's been a major challenge in London Underground in order to get that through the system." 

Although LED lighting has a higher investment cost, London Underground will see fast payback due to LED lighting's significant reduction in energy consumption and maintenance costs. The longer lifetime offered by LED lighting is a massive benefit to the London Underground maintenance team as conducting maintenance in busy, hard to access stations has an extremely high cost.

A number of London Underground stations have already been upgraded from costly T8 fluorescent lamps to LED tubes. This change-over saw a return on investment in 18 months and has saved millions of pounds in maintenance costs. 

Speaking of the astronomical savings, Benn said: "From the point of view of whole-life cost, we're very aware of the reduced maintenance of new technology."

London Underground estimate that work at Bond Street will be finished by 2017, while work at Victoria and Tottenham Court Road will continue until 2018. These redevelopments are part of a London wide scheme of station upgrades to prepare for the completion of Crossrail.
