The late 1970’s design for the Rosie Maternity Hospital on the Addenbrookes campus in Cambridge is a recurring type across the UK National Health Service, a framed three storey courtyard configuration in brick masonry. It was selected as a case study project for the ‘Design and Delivery of Robust Hospitals in a Changing Climate’ (DeDeRHECC) project, pursuing the methodology developed for that research. Environmental data was collected within representative spaces within the hospital, with some difficulty, over a two year period revealing overheating in mild conditions relative to a 24o C threshold for sleep but concealed within the customary 28o C threshold marking the upper limit of acceptable conditions. The building was modeled against current climate data to predict 2010 conditions, calibrated against observed data in 2010, and then against the CIBSE predictive climate database for the 2030’s for the location suggesting a progressive deterioration in peak conditions. Four adaptive intervention schemes were subsequently developed: an ‘enlightened’ industry standard ‘passiv-haus’ option of super insulation, sealed glazing and heat recovery; a lower technology based scheme promoting natural cross-ventilation by providing greater opening glazing area, opening up the plan, sun shading and additional insulation; an enhanced natural ventilation scheme glazing over the courtyards to provide supply air winter gardens, and an advanced natural ventilation option pursuing Passive Downdraught Cooling. All four schemes were modeled against the predictive climate database, their performance compared and the schemes fully costed to yield relative ‘value for money’ guidance to Trusts.
This work was undertaken at part of the UK Engineering and Physical Sciences Research Council project, ‘Design and Delivery of Robust Hospital Environments in a Changing Climate’ [grant number EP/G061327/1] through the ‘Adaptation and Resilience to a Changing Climate’ (ARCC) programme under the auspices of the ‘Living with Environmental Change’ (LWEC) initiative. The Project also received funding directly from the Department of Health.
