JGC was appointed by Cambridge University Press & Assessment to deliver a detailed MEP design up to RIBA Stage 4, followed by client-side monitoring support for the Triangle Building decarbonisation project. To ensure full operational resilience, backup electric boilers were incorporated. This upgrade eliminates the building’s reliance on natural gas, achieving the complete removal of Scope 1 emissions and significantly reducing its overall environmental impact.

To meet the building heating load, a modular air source heat pump solution was developed within the available dimensional and acoustic envelope, having studied the building's peak thermal demand within two years of historical data.

The use of multiple modular heat pumps operating under cascade control also enables high part-load efficiency, with each module capable of cycling on and off to meet varying heating requirements throughout the year and ensures high levels of system redundancy.

The project was successfully completed while maintaining full, continuous building operations. This required close collaboration between JGC, the client, the contractor, and the wider design and delivery team to ensure a seamless transition to decarbonised heating, without compromising the comfort or needs of building occupants. We are over six months into our monitoring phase, with no reported issues affecting system performance.
