Energy and heating improvements bring further reductions in carbon emissions

The University is ready for winter, after major investment in the campus heating infrastructure.

Six energy-efficient boilers meet the University’s winter heating needs for the campus buildings.

With temperatures starting to drop, it’s the time for the heating to come on at the University of Sussex.

To prepare for the arrival of autumn, and in keeping with the University’s environmental agenda, the campus heating system has been upgraded to meet current and future development needs.

Six energy-efficient boilers will meet the University’s winter heating needs for the campus buildings – with an increase in energy capacity of nearly 80%, from 13.4MW to 24MW. 

State-of-the-art controls will continually monitor the efficiency of each heat generator. As the operators review and log these individual boiler efficiencies, they can energise the most efficient boilers at all times.

Meanwhile, new variable-speed water pumps, fully automatic controls and an array of sensors have been strategically positioned around the campus to monitor and record the energy needs of each building.

This means that the boilers in the energy centre can react more effectively to changes around campus, which in turn improves the overall efficiency of the system.

Francine Hill, Deputy Director of Estates, says: “The heating coming on is one of the sure signs that winter is on its way – and we’re ready for it, after major investment in our campus heating infrastructure.

“Our six boilers will improve our energy efficiency and reduce the impact of new buildings as we strive to achieve our ambitious carbon-reduction targets.

“The University now has a heating system that will support the growth and renewal of the campus in the long term, as well as reducing heating costs and dramatically improving our carbon-emissions profile.”

The energy centre in the Boiler House also houses a 1.2MW Combined Heat and Power (CHP) unit, which generates heating, power and hot water for the campus.

Installed in 2007, the CHP supplies about one-third of the campus electricity demand from Monday to Friday and almost half every weekend.

In recent years, significant energy savings have been achieved with a number of measures to improve the efficiency and output of the CHP, such as improvements to engine performance and an increase in operational hours.

  • In 2017, the University of Sussex began an ambitious journey to become one of the greenest universities in the UK and is working towards cutting its carbon emissions by 45 percent by 2025.
