We spend 230 every hour, day and night, on energy to heat, light and power our academic buildings and accommodation.

We have an active programme to improve our energy efficiency and generate power on-site in order to cut our carbon emissions and energy costs.


Carbon & Energy management plan this forms the energy section of our Environmental Strategy, and outlines how we intend to deliver our targets to reduce carbon emissions by 43% by 2020 compared to 2005/06.

Carbon management working group chaired by our Director of Estates & Facilities Services, this group oversees implementation of our Carbon & Energy management plan Plan and reports to our Board of Governors via the Corporate Management Team. See the terms of reference.

Heating & Cooling Policy this outlines the temperatures to which we will heat and cool our buildings and the associated actions for staff, students and facilities managers.

Eco Residents this is our annual competition for students living in our accommodation to see who can reduce their energy consumption the most compared to the previous year.

Good practice simple changes in our behaviour can reduce our energy bills by up to 10% according to the Carbon Trust, that‘s £230,000 for us. The following energy saving tips will help achieve these savings.

Electrical devices and appliances

  • Ensure your computer monitor and unit is switched off when not in use, especially overnight and at weekends.
  • The monitor is the most power hungry part of your computer – don’t use a larger one than you need, 17” is fine for most uses.
  • Don’t use screen savers at all.
  • Configure your computer to go into a low-power or sleep mode after 10 minutes of inactivity.
  • Thin client computers use significantly less energy than desktop PC’s – request that your PC is replaced by a thin client if you can.
  • Ensure that kitchen equipment is cleaned and maintained regularly and switched off overnight, or put on a time switch.
  • Establish a maintenance regime for equipment such as freezers or compressed air systems.
  • Agree switch off procedures at the end of the day for lighting and equipment such as shared printers – see our download section for stickers to help with this.
  • Unplug mobile phone and tablet chargers when not in use.
  • Always think energy efficiency when making new equipment purchases.

Heating & Cooling

Turning the thermostat down 1C saves 8% in heating costs.

Nearly 50% of the CO2 emissions produced by the UK come from heating and cooling in buildings.

A typical window left open overnight in winter will waste enough energy to drive a small car over 35 miles.

  • Allow warm or cool air to circulate within your workspace – don’t block radiators or floor/wall vents with furniture or other items.
  • Avoid using portable electric heaters. These can interfere with a building’s main heating system by sending a message to the thermostat that the building is at temperature or too warm, and stop the heating to the whole zone (which may be an entire floor), or even activate the cooling, reducing comfort levels for colleagues. They also increase the load on a building’s power circuits, can present a fire risk, and cost up to 3 times as much as central heating.
  • Avoid using portable air-conditioning units which will have the same effect as portable heaters but in reverse, potentially activating the heating. They are also likely to be ineffective as they require an air outlet, otherwise they will discharge warm air within the office and try to cool it again.

Lighting

  • Switch off lights at the end of the day or when daylight is sufficient.
  • Report any faulty light sensors to the Facilities Helpdesk on 6464 e.g. corridor lights that are on when daylight is sufficient.
