As part of the upgrades and decarbonisation project, a centralised ASHP replaced the steam generation plant within the energy centre. From here, the heat was then distributed to plate heat exchanger plantrooms.

 

The BMS element of the works was the optimisation of existing control strategies to include modifications to plant which also included the revision of system setpoints, changes to occupancy schedules and related optimiser control settings, the revision of existing heating economy control, the delivery of new heating economy control, and the delivery of new night setback strategies

 

The scheme also included a central weather station which measured the ambient temperature and communicated that temperature across the BMS network to the new compensated heating and temperature cut-off strategies.

 

The project at Northampton General Hospital focused on decarbonisation and efficiency by upgrading to a more reliable, efficient centrally-fed heating system. Integrated with the BMS, it provided end-users greater visibility and confidence in the system's performance while aligning with sustainability goals.
