H&K wins Better Healthcare Award
Hulley & Kirkwood were delighted to win the Sustainability Class of the 2013 Building Better Healthcare Awards for Innovative Alternative Use of Energy for its work at Fife Acute Hospital. This award recognises a product, process or service that has utilised alternative forms of power to reduce energy use and cut costs within the healthcare estate.
Hulley & Kirkwood were Services Designers to the Balfour Beatty Fife Hospitals Joint Venture (BBFH JV) team on the new £170 million facility at Kirkcaldy’s Victoria Hospital. The new Fife Hospital brings together three hospitals under one roof with the re-alignment of services across Victoria Hospital and Park Hospital, Kirkcaldy, and Queen Margaret Hospital, Dunfermline. The facility includes 11 operating theatres (3 of which are UCV laminar flow style vascular theatres), interventional radiology theatre, catheter lab theatre, endoscopy cleanroom, diagnostic suite with CT scanner and X-ray machines, infectious diseases ward with 10 single HBN 4 style isolation rooms, an emergency care centre, 508 beds within 20 wards, surgical and medical assessment units, a maternity unit, a women and children’s unit, day intervention, critical care, coronary care and renal and dialysis facilities – in total over 50,000m² of accommodation.
Two notable features of the project are the extensive use of prefabrication for the M&E elements of the project, and a new energy centre providing the electrical supply and standby power generation for the entire site. Hulley & Kirkwood and Balfour Beatty now have 30 years of successful collaboration together on the use of modularisation in major health care projects. Using offsite prefabrication for the M&E elements of the project provided a more-sustainable way of delivering the scheme by reducing waste. It also reduced time by 270,400 man hours compared to a traditional M&E approach.
The new energy centre serves the retained estate on the site by supplying a new MTHW distributed heat source. The existing retained estate steam mains are to be decommissioned over time and replaced with this low-carbon heat source. The energy centre features a 725kWe combined-heat-and power plant, two 1MW wood-chip boilers, thermal accumulators, a 300sq m below-ground bunker for the wood chips, and an automatic wood-fuel feed system for the biomass boilers.
The CHP unit and biomass boilers provide base-load heat demand and power for the new facility to reduce energy costs and carbon emissions. Together they are expected to reduce carbon emissions by over 1,400,000kg a year. Dynamic simulation modelling of the building and envelope by Hulley & Kirkwood identified the optimum levels of thermal insulation for walls, floors, roofs and glazing. In addition, solar glazing to those facades exposed to the sun resulted in smaller heat gains. Air-handling plant for ventilation includes heat recovery to recover about 800kW of heat from exhaust air systems. AHU and pump motors operate under variable volume auto control regimes.
To help keep the building running efficiently, the building-management system monitors energy meters to enable the early recognition of operational problems so they can be diagnosed and rectified quickly. The project was described by the judges as ‘a highly-successful example of how a carefully-considered design, co-ordination and construction method derived through designer/contractor collaboration can help to safely deliver a sustainable and cost-efficient new healthcare facility’.
