Ysbyty Aneurin Bevan,
Ebbw Vale, South Wales

Ysbyty Aneurin Bevan is a Local General Hospital providing 96 Inpatient single bedrooms, 11 Mental Health bedrooms, MHU Day centre with the Community Mental Health Team, along with general Outpatients, Therapy, Radiology, Minor Injuries and Birthing facilities.

The hospital is located on a former steelworks site in Ebbw Vale and is designed to respond to the local Masterplan applicable to the remediated site. A local Landscape and Biodiversity management plan, Travel plan and Sustainable Energy Strategy were submitted at the outset of the planning process. The hospital also directly incorporates a number of sustainable design principles:

• The cut and fill of the gently sloping site was carefully calculated to ensure no excess material was removed from site.
• A biomass boiler provides all heating, hot water and underfloor heating to selected locations. A Building Management system monitors and maintains an appropriate environment to zoned areas and accounts for the unique seasonal adjustment required in this location.
• A mixed mode ventilation system uses natural ventilation where possible with mechanical supply or extract to appropriate clinical areas. All patients have the facility to moderate their immediate environment via the large openable areas to individual bedrooms.
• Large areas of glazing to communal rooms, as well as individual bedrooms, provide maximum natural daylighting and allow excellent views to in to either landscaped courtyards or extended views along the valley. External terraces also allow direct patient access to a sheltered external area.
• External brise soleil provides shading to South East and South West facades and has been tested through an IES thermal modelling system to prevent overheating.
• Materials were selected to be recycled where possible and/or recyclable and timber is FSC certified. The average U-value is 0.38W/m2K. Contractor waste was minimised during construction and operational waste is separated on site for recycling collection.
• The completed building achieves an Air permeability rate of 3.3m³/(h.m²) at 50Pa and annual CO₂ emissions of 22.6 KgCO₂/m².

The hospital was designed to maximise the potential of the site and responds positively to the unique microclimate experienced in this location, providing an open, welcoming and therapeutic environment for patients and staff. The above factors have contributed to the achievement of an ‘Excellent’ NEAT assessment (score 76.6%) and an ‘A’ rated (score 20) energy performance certificate.
