District Heating Systems – what would a forensic study of your system reveal?

Last updated: 11th November 2019

Annual cost-savings of 60-70% are expected following a forensic study and optimisation of the district heating system at Bristol University. Is your DHS giving your organisation best value? This is how we did it for Bristol University.

Bristol University has a long history of action on sustainability and has several teams working on sustainability activities, including the Estates Sustainability Team.

The university’s district heating system (DHS) at its Langford Campus serves a high percentage of the buildings including research and accommodation plus common areas with two independent energy centres for primary thermal energy for space and domestic hot water.

The Challenge

The Sustainability Team knew the system to be inefficient and wanted to know:

  • The least-cost path to using the thermal store better.
  • How to best serve under-utilised buildings.
  • If increased efficiency could be achieved by linking two networks.
  • If biomass could be cost-effectively integrated into the mix

The Solution

The Green Consultancy (TGC) (a subsidiary of JRP Solutions) was commissioned to carry out a forensic study to reliably deliver the required objectives and provide a firm foundation for making all future decisions about the DHS. The study resulted in recommendations for cost-effective solutions to improve and/or rectify problems based on prioritised works with budget costs identified. TGC then redesigned the DHS based on its recommendations and supervised the progressive commissioning. 

Results

The cost of progressive implementation of the new design was more than covered by the value of the immediate energy savings and it is expected that annual cost-savings of 60-70% will be achieved.

“The consultant gave a clear and concise explanation of the new design and fully inspired our confidence in the results. At last we have someone who understands CHP and thermal stores!”
