Great Ormond Street Hospital, GOSH (UK)
Great Ormond Street Hospital for Children (GOSH NHS Trust) is situated in Bloomsbury, central London, adjacent to the British Museum and Russell Square.
The hospital site is under going a number of phased redevelopments. The project period will cover Phase 2 of a planned 4 phase re-development of the complex hospital site and Phase 2 needs to be completed by 2011. One of the project objectives is to provide an exemplar sustainable hospital design to influence the future UK hospital build programme estimated to cost £15bn.
Aim
The objectives from the strategy document for the development are as follows:
- Achieving the lowest energy use for the new hospital buildings whilst meeting staff comfort issues, clinical needs and best value
- Delivering a cost effective heating and power strategy for the site which minimises emissions responsible for Climate Change.
- Delivering a sustainable solution which best meets the user and community needs, wishes and aspirations
- Provide an integrated, overarching site strategy with buy in from all parties
- Good project co-ordination and management
- Developing site solutions which take full account of it’s operation, maintenance, and durability
- Delivering a development to inspire future projects
Energy Design
The key aspects for the design are shown in the diagram below:
The energy target of the redevelopment Phase 2 is 53 GJ/100m3, which compares to a typical KPI for new UK hospital projects of 67GJ/100m3 (with a typical ceiling height of 2.9 m this equates to 540 KWh/m²).
The new hospital will have a performance of approximately 425 kWh/m². Note that this is a delivered energy basis, with no further allowance for renewables contribution or the benefits of CHP.
Emissions of carbon dioxide and other climate change gases is expected to be approximately 50% less than the existing buildings, With full implementation of the biofuel options the carbon emission reduction is estimated at over 70% of present levels.
