£1.4m project cost delivered over two phases
Complex project delivered in working hospital
Annual cost savings of approx. £130,000
Approximately 1,000t annual CO2 savings
Following the detailed survey and analysis, Sussex Community NHS Trust engaged Zenergi to support the implementation of the recommendations by providing detailed mechanical and electrical (M&E) design and project management services.
The programme involved replacing large inefficient central steam boiler plant and distribution systems with high efficiency independent local condensing boilers with a fully automated building management control system to provide centralised heating control across the site.
The domestic hot water calorifier systems were also replaced by a mix of high efficiency plate heat exchangers and point of use water heaters, significantly reducing secondary circulation losses.
This project itself has resulted in the site’s carbon emissions being reduced by over 30% and has assisted the Trust in exceeding its statutory carbon emission reduction targets and contributed to being awarded ‘Winner’ in the category of Good Corporate Citizen in the prestigious Health Service Journal awards.
