ARCHITECTURE & DESIGN


the P22 repeatable room, which enables the sink, toilet, and shower, to be fed from the one duct without the use of shower towers.


On the flat roof areas just off the main


spine are the building’s air-handling units and solar thermal panels, which serve the ventilation and hot water heating for each ward. Photovoltaic panels are provided on some of the south facing-pitched roof areas.


Sustainability and Net Zero carbon The new Park House development will be one of the first of a new generation of Net Zero carbon NHS hospitals. MEP consultants, Ramboll, worked tirelessly with the rest of the design team to create a strategy that will enable the building to operate with Net Zero carbon as the national grid decarbonises. Using the RIBA Sustainable Outcomes Guide as a benchmark, the project is designed to better the 2020 operational target of <175 kg CO2e


/m2 . This is achieved by utilising


heating and cooling reverse cycle air source heat pumps, solar thermal hot water production, and photovoltaic panels. The embodied carbon of constructing the building is also addressed as a high priority. Using the RIBA Sustainable Outcomes Guide as a benchmark, the project is using the 2020 targets of <800kg CO2e


/m2 , and is forecast to beat

the target. As part of the embodied carbon assessment, a variety of construction methods were considered with contractor, IHP, and structural engineers, Curtins. These in turn also factor in the new MMC targets as part of the business case approval. Cross-laminated timber, SIPS, SFS,


and pre-cast concrete panels, were all considered. Full prefabricated panellised systems, while potentially beneficial, were eventually rejected due to value for money and on the limitations on future flexibility. A steel frame with SFS system was selected. Concrete specified for the foundations is as sustainable as possible, using the low carbon GGBS type. The quantity of Modern Methods of Construction is planned to far exceed 55% by project value. The project is also targeting ‘Excellent’ for ‘BREEAM’ Healthcare 2018.


Programme With the scheme’s full business case recently approved by central government, construction is estimated to start in August this year, with the building expected to open roughly two years later. The development will be phased as follows: l 2022: Demolition of existing buildings on site, e.g. Trust HQ building and obsolete energy centre.


l Enabling and groundworks. l Construction of new building. l Construction of new road to the west of the site as part of the wider NMGH masterplan.


l 2024: Decant of existing Park House. New hospital opens.


l 2024/2025 onwards: Existing Park House to be demolished to make way for wider NMGH masterplan development.
