Joseph Priestley Building

The Joseph Priestley Building is home to Queen Mary University of London’s (QMUL) chemical scientists. QMUL recently invested £5.2 million into the building’s refurbishment, including a new undergraduate teaching lab to create a cutting-edge learning and teaching space.

QMUL is an award-winning investor in energy-efficient buildings. As a trusted energy consultant to QMUL, Carbon Numbers surveyed the site, modelled the data and completed the specification for the tender and business case for the upgrade.

The project was to remove four oversized cast iron hot water generators that were old, broken and inefficient and replace these with Heat Plate Exchange Buffer Vessels. These were then tapped into the main boiler primary loop circuit. CTS was awarded the installation project and worked with Carbon Numbers in partnership over 12 weeks to deliver the change.

The Heat Exchange plates work a lot more efficiently due to transferring heat continuously from one media to another without adding energy to the process.

The system was connected to the site CHP and is managed via the BEMS.

Keys Facts

  • Full turnkey solution
  • Full Modbus integration with the BMS.
  • Lower water content of the Heat Plate Exchangers transfers heat quickly.

Benefits

  • Uses less gas helping significantly reduce energy consumption.
  • Less heat is lost and wasted; high heat transfer makes it highly efficient.
  • Compact size, saving space on site.

Tim Lee, Technical Manager, Queen Mary University of London commented:

“The latest contract with Carbon Numbers is a further indication of QMUL’s commitment to reducing its annual carbon emissions and creating better conditions for those working in our facilities. The collaboration between the team at Carbon Numbers and our internal QMUL team fostered a productive relationship that has resulted in the desired reduction in gas usage and heat loss. Having worked in partnership with CTS to deliver the desired outcomes, we are confident that QMUL has invested in a smart solution to better the environment and reinvest energy savings into other facilities.”
