New hospitals for Leeds set for a sustainable future
Leeds Teaching Hospitals NHS Trust has set an ambition to meet new standards for greener and more sustainable hospitals in the UK, as part of its Hospitals of the Future Project that will see the construction of two new state-of-the-art hospitals in Leeds.
The Trust has explained its original design briefing for the new hospitals featured issues surrounding sustainability and environmental impact including energy, carbon emissions and the use of sustainable construction methods and materials.
The new hospitals, which will incorporate Leeds Children’s Hospital and an adults’ hospital at Leeds General Infirmary (LGI), will be built on parts of the old LGI site that are currently being demolished. The project is part of the Trust’s Building the Leeds Way (BtLW) programme.
Simon Worthington, Leeds Teaching Hospitals NHS Trust director of finance and senior responsible officer for the Building the Leeds Way programme, said: “It is the Trust’s goal to become one of the greenest NHS Trusts in the UK and we’ve made great strides in the last few years towards making that happen in our current operations.
“But the building of the new hospitals, and the redevelopment of large parts of the old LGI site, will be the biggest development in the city centre in a generation. We knew from the outset that it is vital that the new hospitals should be designed and constructed to a rigorous set of requirements, to ensure the construction of environmentally responsible buildings, not just for today but for the next 60 years and beyond.
“To that end we made it plain that we wanted to see an integrated approach from our designers that provides world class patient facilities that minimise waste; minimise energy use by using renewable energy sources, construction materials and methods; and strives to support the Trust in delivering its ambition towards achieving net zero carbon.
“We’re pleased and impressed with the outline proposals put forward by our architects Perkins & Will and our other design team members including WSP who are the design lead for sustainability and net zero carbon. The proposals seek to address our sustainability criteria with a holistic, whole life-cycle approach to focussing upon net-zero carbon and which also seeks to deliver against construction industry benchmark standards such as WELL and BREEAM.”
Mike Bacon, Building the Leeds Way programme director, added: “Close collaboration between the BtLW Programme Team and our designers will support the ambition to deliver truly sustainable, long-life buildings that will be fully adaptable to the changing nature of healthcare.
“Having a patient-centred approach has also led to the design of a building with plenty of natural light whilst the whole-life carbon impact of the building will be minimised through the careful selection of materials. Heat will be preserved through high levels of insulation and the provision of window areas that efficiently balance the penetration of daylight and heat loss.”
He noted that sustainability is not just important in the design and build phases of the new hospitals but that the same thought mus also go into those parts of the Leeds General Infirmary site that are being cleared to make way for the two new hospitals.
He said: “Working with DSM Demolition, we plan to recycle between 95% to 99% of the old buildings, with current recycle rates running at approximately 97%, with brickwork crushed and used for hardcore in the construction industry, and metals recovered from the site being weighed in and melted down for reuse.”
The Trust has also outlined a number of the sustainability measures currently being considered for the new hospitals which include:
- Rainwater collection and bio-filtration
- Grey water reuse
- Onsite solar energy harvesting
- Passive design & energy re-capture (the capture and reuse of waste heat)
- Maximising the capture and use of natural light
- Natural ventilation
- Proposed provision for bird, bat and bee hotels
- Outdoor gardens and terraces
- Sophisticated energy management systems that maximise energy efficiency and minimise waste
The concept design now needs to be developed further through a robust design development process involving a range of stakeholder inputs, including staff, patients and partners. It is planned that the new facilities in Leeds will be fully operational in 2027.
