Energy & Water

Detailed here are just a few of the projects we have or are in the process of implementing on our campuses to improve our efficiency in energy and water consumption.

For more information on any of these projects, please contact

To find out what more you can do as a member of staff or a student have a look at our Quick Tips

Lighting Awareness

As part of the University’s Carbon Management Plan there is a programme of lighting change across the campus to replace the old, energy inefficient light fittings with new energy efficient LED lighting, along with associated lighting controls. It is estimated lighting accounts for around 25% of electricity and 30% of the University’s Carbon Footprint, so it makes sense for this area to be heavily targeted. The new light fittings don’t suffer from flicker and therefore give a more relaxing environment to those susceptible to this phenomenon. These new lights will also save the University money and generally have a payback of less than 3 years (on 24-hour applications the payback is less than 2 years!). Some of the projects already carried out include:

  • Replacing all the corridor lights in Technology House with a mixture of LED tubes and LED flat panels.
  • Mary Seacole lights in corridors and lecture theatres have been fitted with PIRs (Passive Infra Red) sensors that detect movement to turn the lights on, automatically switching lights off if no movement is detected after a set amount of time, and Lux sensors, which detect the levels of natural light and switch the lights off if a certain natural light intensity is reached.
  • Maxwell canteen, reception and shop area lighting has been changed to a mixture of LED panels, downlights and 2D lights.
  • Allerton corridors and staircases have had their inefficient T8 and T12 tubes replaced by LED lights. So far we estimate on overall saving of 106,869kg CO2/yr, but there are many more projects in the pipeline, including both light replacements and lighting controls installed.

What can you do?

If you notice any lights in your buildings which are GU10 lights or filament lights please email

Please report any flickering lights to the Estate Helpdesk on 54444.

Draught Proofing

The University is embarking on a programme of draught proofing some of its worst offending buildings. Currently Crescent House has been fully completed and work has started on Maxwell Building. Gaps in walls and around window and door space can lead to a building losing as much as 50% of its heat, with up to 20% lost through walls and 30% through windows and doors. Excess heat loss from a building means its heating system has to work harder to maintain a comfortable temperature. This results in higher fuel and maintenance costs.

How it Works

The buildings were thermally assessed to see where proofing was needed as it shows the greatest differences between the cold air seeping into the building and the hot air being pushed out. It is important to ensure that the building is still adequately ventilated to allow the flow for fresh air into the building, and allow the removal of moist air and burnt fuel from appliances. Sealant is applied to metal, wood, aluminium, PVC and glass effectively blocking any unwanted gaps especially around window and door frames while still allowing the windows and doors to open to aid ventilation.


  • Faster warming times
  • Better heat retention
  • Possible 25% energy saving as per the BRE report
  • Outside noise reduction
  • Increased comfort levels
  • Pay Backs

Crescent house and Maxwell are notoriously prone to heavy draughts. The cost and predicted paybacks are predicted to be as follows:

CRESCENT – Cost of install = £14,500, Savings = £4,250 & 22.5t/CO2/yr, Payback = 3.8yrs

MAXWELL – Cost of install = £37,400, Savings = £9,950/yr & 52.2t/CO2/yr, Payback = 3.8yrs
