The Communities and Local Government department administers energy efficiency in the UK. Now it’s getting its own house in order

Eland House in Victoria is the London home of the government department that administers the UK’s energy efficiency legislation – Communities and Local Government.

Sadly, the lighting installation in the building was far from a textbook example of efficiency. The place was packed with louvred fittings, each with a pair of 36W PLL fluorescent lamps. A passive infra-red sensor in the middle cell was a half-hearted nod to energy saving.

CLG was determined to improve efficiency at Eland House and put the lighting contract out to tender. The contract went to Etap, which installed 3,849 fittings with a single 36W lamp into the existing 500 x 500mm apertures. How did it do this without sacrificing light levels for the civil servants?

The secret is Etap’s UM fittings, which incorporate its MesoOptics diffuser technology. Microscopic prismatic structures in the diffuser material distribute the light from the single lamp in a controlled way, and there are almost no light-absorbing reflections in the material itself.

The fittings also incorporate daylight sensors and motion detectors.

Before the upgrade - no textbook example

Etap has also supplied a thousand UM1 fittings with two 24W T5 lamps for CLG’s Birmingham office. Both projects were managed by Mitie Facilities and GI.

Something for nothing

No money to bring down those energy bills? Don’t worry, let your suppliers pay for the lighting upgrade and take a share of the running cost savings. Andrew Brister visits a self-financing retrofit project
