IN Brief:
- Morgan Sindall has handed over the University of Oxford's 4,700 sq m Global Health Building at Old Road Campus.
- The building achieved 0.19 air changes per hour at 50 Pa in airtightness testing, against a target of 0.60.
- The contractor reports 27 apprentices supported and 39 jobs created during the construction programme.
Morgan Sindall Construction has handed over the University of Oxford’s £35 million Global Health Building at Old Road Campus in Headington, completing a 4,700 sq m facility designed for research, teaching and collaboration. The three-storey building includes a basement and will accommodate approximately 400 people across teams working on global health. Its environmental specification demanded close coordination between the building envelope and ventilation systems, with Passivhaus principles central to the design of its envelope and building services.
Within the completed building, the Nuffield Department of Medicine’s Centre for Global Health Research will work alongside Oxford Population Health staff and students and members of the Oxford Global Health team. Offices, teaching areas and shared workspaces bring teams previously spread across different locations into one facility. Before handover, Morgan Sindall completed the internal fitting out, installed the building services and undertook commissioning and checks needed to bring the occupied accommodation into use.
Associated Architects designed the accommodation to combine flexible research and teaching space with the energy demands of a densely occupied building. With offices and meeting rooms distributed across three floors, the arrangement of circulation routes and building services had to support different activities while providing controlled ventilation and consistent indoor conditions. Those requirements link the internal layout to the performance of the external fabric and mechanical systems.
Reducing heat loss and uncontrolled ventilation was a central part of the specification developed around Passivhaus principles, so the building’s insulation, airtight layers and mechanical ventilation were developed together. Insulation limits heat transfer through the envelope, while sealed joints restrict air leakage at connections between components. Ventilation with heat recovery can then supply fresh air through controlled routes, recovering some of the heat from outgoing air rather than relying on leakage through the building fabric.
The continuity of that envelope was tested after construction, when Associated Architects reported airtightness of 0.19 air changes per hour at 50 pascals against a target of 0.60. The result reflects detailed work around window frames, structural connections and service penetrations, all of which can form leakage paths if poorly sealed. High performance insulation works alongside the airtightness measures, while heat recovery ventilation transfers heat between outgoing and incoming air streams without mixing them. The recorded test is evidence of airtightness performance, not a substitute for a confirmed final certification decision.
Airtightness alone cannot control summer temperatures, and the design also uses window positioning and solar shading to moderate heat gains while allowing daylight into occupied rooms. The university’s project team considered how glazing would affect winter heating and the risk of overheating in warmer months. By balancing those effects with the building envelope and ventilation strategy, the design aims to limit energy demand, although measured consumption will depend on occupancy and system operation after handover.
Constructing those details required the intended airtight layer to remain continuous through successive building trades, rather than ending at the edge of an individual component. A poorly sealed service penetration or gap at a window junction can reduce performance of the whole building even where insulation elsewhere has been correctly installed. Ventilation plant must likewise be commissioned so that airflows meet the needs of occupied rooms. Morgan Sindall completed building services installation and final commissioning before transferring the facility to the university.
After the main structure reached its highest point in July 2025, the construction sequence moved through enclosure, internal works and mechanical and electrical installation. Completion and handover followed in October 2026, after testing and snagging. The latest contractor figures put the building’s capacity at approximately 400 people, working across research, teaching and collaborative spaces on the Old Road Campus.
Alongside the operational energy strategy, the project used sustainably sourced materials and construction measures intended to reduce embodied carbon. The architects identify lower carbon concrete, timber elements and photovoltaic generation within the design. Material production, transport and construction create emissions before the building begins operating, whereas electricity and heating demand arise over its useful life. The disclosed project information provides no measured embodied carbon total for the entire building or verified percentage reduction.
Deliveries and site access also had to be coordinated with the surrounding research campus, whose neighbouring facilities remained in use during construction. Organising material movements and disruptive activities around occupied buildings placed constraints on working areas and programme sequencing. Morgan Sindall drew on its experience of education and research projects, although quantified disruption or logistical performance figures have not been reported for this site.
The contractor reports that 27 apprentices were supported and 39 jobs created during the construction programme, alongside the work undertaken by the wider delivery team. Those figures describe employment and training during construction, distinct from the staff and students expected to occupy the completed facility. They form part of the handover information for the £35 million project.
With the building now handed over, the reported airtightness result and commissioned ventilation systems provide a foundation for its planned energy performance, while actual consumption will depend on how occupants use and maintain the facility. The University of Oxford aims to reach net zero carbon by 2035, and the Global Health Building is intended to contribute through its efficient envelope and building services. Its 4,700 sq m of accommodation is available for the research and teaching groups brought together by the project.
