DECC HQ slashes energy use
ʹapp Department of Energy and Climate Change has been awarded a new, improved Display Energy Certificate (DEC) rating of ‘C� for its headquarters�

ʹapp Department of Energy and Climate Change has been awarded a new, improved Display Energy Certificate (DEC) rating of ‘C� for its headquarters building.
A DEC is measure of the energy efficiency of a building, which is rated on a scale of A to G, with A being the most efficient and G being the least.
On moving into 3 Whitehall Place in Autumn 2008, it had a ‘G� rating. Since then DECC has made improving its energy efficiency and carbon emissions a priority, including the publication of its first ever Carbon Management Plan in July 2011.
Greg Barker, Minister of State for Climate Change said:
“ʹapp new higher DEC rating of “C� represents a great achievement for the Department over the last four years. Only 23% of commercial buildings are rated C or above.�
“Since 2008, the Department has cut its HQ building’s energy consumption by 60% and slashed carbon emissions by half. This is even more impressive when you consider that staff numbers in the building have risen since DECC took it on.�
“With the right commitment, large organisations can make a big difference to their overheads and to their environmental impact, and DECC’s achievement is proof of that.�
Based on current energy prices, we estimate to have saved around £156,000 in 2011/12 on energy bills as a result of the savings achieved, and expect to see even higher savings in 2012/13.
ʹapp Department has mainly achieved its new and improved rating through various building management projects, including:
- the introduction of more occupancy controls on lighting in the building:
- the installation of intelligent boiler load optimisation control units to two gas-fired boilers and;
- the installation of variable speed drives to supply fans.
ʹapp new DEC rating runs out in July 2013. In order to maintain this rating, there are a number of energy saving projects planned for the coming year that are estimated to shave a further 4% of the footprint of 3 Whitehall Place.

Two other sustainability reports published today on the DECC website include:
- GGCs are the Government’s commitments for delivering sustainable operations and procurement for the current parliament. This document summarises DECC’s performance against the GGC targets for the 2011/12 financial year.
Notes for editors
- A DEC is a mandatory requirement for all public buildings over 1,000 m² and must be displayed in a prominent place.
- ʹapp DEC rating of 3 Whitehall Place has steadily improved with a G rating in 2008, an F rating in 2009, E rating in 2010, D rating in 2011 and a C rating in 2012.
- DECC achieved a B rating for its other main building, 55 Whitehall, in January 2012. ʹapp building had a D rating when DECC took it over in April 2011.
