A 215 bedroom Hilton Hotel in Liverpool formed the final phase in the £920 million, 42 acre, Liverpool One development by Grosvenor. A striking curved building by international architects Aedas, it echoes the elegant lines of Bath’s Royal Crescent. The hotel overlooks Chavasse Park, a new public open space and includes facilities such as top class restaurants, bars, health club, meeting rooms and conference suites.
Exyte Hargreaves supplied the HVAC ductwork for the hotel working with Kier Build Limited is the main contractor. The contract also included ventilation for 47 luxury apartments within the same building. Exyte Hargreaves supplied and installed the backbone ductwork for air delivery and removal along with the smaller final connections.
The Hilton Hotel energy conservation was a key principle in the HVAC design. Heat recovery was therefore used on exhaust systems and rates of ventilation are closely related to occupancy and under the control of the building management system (BMS). The heating and ventilation ductwork installation took place during a 43 week fit out phase. Kier Build was responsible for design, construction and management of the services fit-out with Kier’s in-house M&E department.
For maximum flexibility and to give guests control, air input to bedrooms is cooled or tempered by individual fan coil units regulated by room thermostat. This conditioned air is delivered via a bulkhead plenum and grille into the room. Extract from bathroom pods is via a single blade damper connection to 125mm galvanised ducts that feed into the main extract systems.
Plant rooms, some totally closed and others open to the sky, are located at mezzanine and roof level. Staff kitchens in the basement and the restaurant kitchen at ground floor level are ventilated by Exyte Hargreaves HFD kitchen extract fire duct. The insulated duct has access panels to permit thorough cleaning.
Exyte Hargreaves standard specification stability, integrity and insulated HFD ducting was also used for smoke extract from the basement. HFD fire ducts were used to supply the essential make-up air. The smoke extract ducts pass through the building to discharge safely at mezzanine plant room level. The apartments are ventilated on a whole house basis with distribution via 204mm space saving plastic ductwork. These systems also have heat recovery, but are not connected to the hotel BMS. Continuous airflow is maintained at all times with facilities for occupiers to increase rates of air flow, heating and cooling as desired.
