Student-LED library project

The David Wilson Library is switching to LED lighting following a student project that identified an opportunity for energy and cost saving.

The David Wilson Library was originally fitted out with fluorescent lighting during the remodelling and extension work that took place between 2004 and 2008. Since that time, LED technology has become much more efficient and affordable, giving us a huge opportunity to make more energy savings at a reduced cost.

The case for the switch was originally made by students in 2016 as part of their Go Green Week project and received support from over 300 students.

The delivered main benefits include:

  • Reduced power consumption
  • Increased control with new lighting sensors
  • Increased life and decreased maintenance of lamps
  • Minimised light pollution and lower heat output

When the project is finally complete, it will significantly reduce our CO₂ which

A trial was conducted showing that the LEDs would also generate a more comfortable environment due to the minimal amount of heat emitted and more natural quality of light. New customisable sensors were installed to detect daylight and movement, which provided a simple method of control so lights will and automatically switch off when not in use.

The results of this were so promising that funding has been allocated to outfit the entire building. The project will take 6-7 years to complete, with contractors working out of term-time and overnight to ensure minimal disruption to library users.

“This is a great example of students using their voice to make changes at the University. We’re committed to upholding the UN Sustainable Development Goals and encourage staff and students to put forward project suggestions.”

Chrispal Anand, Head of Carbon & Energy

When the project is finally complete, it will have successfully paid for itself – using only 30% of the energy required before. Staff and students will also have a more comfortable working environment that is better illuminated, lower maintenance and has a lower carbon footprint.
