Brighton General Hospital: Heating decentralisation cuts carbon emissions by more than 30%

Zenergi was engaged to carry out out a technical feasibility study and financial appraisal co-funded by the Carbon Trust to assess the practical options and energy saving potential from decentralising the outdated steam boiler plant, distribution and condense return systems at Brighton General Hospital.

Case study highlights

£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

Implementing the recommendations

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.

New regulation is coming into force which means that every organisation’s electricity will need to be settled on a half-hourly basis. By October 2026 all electricity meters will need to be half-hourly. Don’t get left behind. If your meter is one of the circa 30 million affected by the regulation, it will need to be upgraded.
