Home Office energy use

The Home Office is committed to meeting the Prime Minister's pledge to make this government the greenest government ever. As part of this commitment, we will be publishing performance data and figures on our real-time energy consumption.

We were one of the first departments to provide public access to real-time energy use for its headquarters (2 Marsham Street) and we are now able to provide daily updates of energy use at several other buildings. The live energy display allows you to view electricity and gas consumption, cost and carbon dioxide emissions over different periods of time. We are also providing the raw energy consumption data, which is compiled once every 24 hours.

You can take a look at data.gov.uk to see other government departments' energy data.

Carbon management plan 2011-15: a summary

The Home Office carbon management plan was launched in July 2011. It sets out our ambitions on reducing carbon dioxide emissions over the next four years

Join in

We all want to reduce carbon emissions. You can show your support for the department’s commitment to reduce emissions by emailing our sustainable development team at: sustainabilityenquiries@homeoffice.gsi.gov.uk

Send in your name and message of support, or even your ideas on how the Home Office can reduce its own carbon emissions. We can receive support from individuals, businesses, public sector organisations and other organisations. You can look over some of the pledges already made by people at the Home Office.

So get in touch today - it only takes a moment.

Headquarters energy saving projects

2 Marsham Street houses the headquarters of the Home Office, UK Border Agency and Identity & Passport Service, this is about 4,000 to 5,000 occupants. Marsham Street, which opened in 2005, achieved recognition for its environmental credentials during construction and its current display energy certificate is an E rating.

Energy saved so far

At our headquarters we have been working in conjunction with our facilities providers (ETDE) and energy consultants (Energen) to change the way we work in order to save energy.

Changing building temperatures

The normal temperature in the building has been raised this summer, and it will be lowered in the winter, to minimise energy use for heating and cooling.

In addition, humidity levels have been reduced, so that less energy is used for humidification and water.

The changes can be seen in the graph below. It shows energy consumption every half hour on 1 July compared with consumption the next day. The changes were made at approximately 3pm. The dramatic change shown in the graph happened when the heat pumps were powered down.
