Retrofit Project of the Year
Designed in the 1960’s and built in the 1970’s, York Teaching Hospital was typical of the opportunities for demand reduction available in the NHS. With a maintenance backlog, outdated lighting system and BEMS, Vital Energi were able to identify and implement energy generating improvements which would also significantly reduce their CO2 output. Not surprisingly, the 1960’s design didn’t lend itself to a 21st century energy centre layout and was not suited for the access and egress of large, modern plant and equipment. Temporary and permanent structural changes needed to be made to successfully deliver and house the energy solution. The installation team made substantial changes to the building to facilitate an optimised layout. This included removing an old CHP and associated switch gear, which was housed within a brick-breezeblock built room within the existing boilerhouse. This area was demolished to create a new area for a waste heat boiler. The back room in the boilerhouse had been used as a document store. We demolished all internal walls within this area and converted it into the new CHP plantroom to contain all new CHP plant & equipment. This included removing and reinstating external walls to allow delivery of the CHP. 2 existing hotwells were removed and replaced with more modern, 30,000 litre hotwells. Because the building had not been designed to accommodate plant of this size we overcame access issues by removing a portion of the roof, steelwork and lighting to allow the hotwells to be placed one at a time. The roof, steelworks and lighting were then reinstated.
