The Mittal Children’s Medical Centre in Great Ormond Street Hospital (GOSH) consists of two linked buildings with wards, operating theatres, offices and a restaurant. The first phase is on site.
Patient wards will have mixed-mode ventilation operated by the building management system with a manual override. In mid-season, the operable upper quarter of the window will enable fresh air intake. Air will be extracted by mechanical vent-ilation in the en-suite bathrooms. In summer and winter, windows remain closed and chilled beams provide comfort control.
A glazed vertical ventilation shaft is a major feature of the new building’s street elevation. This chimney serves the ground-floor restaurant and provides
a buffer zone to evacuate solar gain from the facade.
