Engineering St Paul’s Hospital, Hong Kong - WSP

Smooth-running services for a tall and complex structure

From its origins as a converted cotton mill, St Paul’s Hospital has grown to become a modern, high-tech medical complex and a crucial feature of the community in Hong Kong’s Causeway Bay.

Almost a century after it opened its doors, the private hospital has taken yet another step into the future with an extensive redevelopment program that includes two new towers of 21 and 24 storeys with a 3-level basement car park. The new blocks will be constructed in phases and will increase capacity from 360 beds to almost 800 beds and provide new medical wards and facilities.

Air-to-water heat pump allows simultaneous pre-heating of domestic water and pre-cooling of fresh air supply

Design Using Latest Techniques

WSP was responsible for the mechanical and electrical engineering consultancy including design, contract preparation, construction planning and site supervision of the building services installations. The firm also ensured normal operation of the hospital during construction.

All aspects of the new building were designed using the latest hospital planning techniques, ensuring a smooth-running facility that can provide the highest care to patients far into the future. As is common in Hong Kong, restricted land supply has pushed St Paul’s to build upwards in order to fulfil its development potential, raising the challenge of how to maximize efficiency in a tall and complex structure.

Energy Efficiency and Flexibility

Our team hit the ground running, wasting no time in designing a building services strategy with energy efficiency and flexibility at its core. It includes, for example, an air-to-water heat pump that simultaneously allows domestic hot water to be pre-heated and fresh air to be pre-cooled, plus a central chiller plant consisting of a single loop system with variable chiller control.

Full CCTV coverage and card reader system ensure patient security

Extensive Use of Technology

Water-saving basins and toilets and occupancy sensors for controlling light and air conditioning in office areas further boost efficiency. Meanwhile, patient security is ensured by full CCTV coverage and a card reader system for door and lift access in designated areas.
