The gas fired boilers plant serving the Ailsa House had passed their 20 year life cycle. Heatwork was commissioned to replace the plant with new ceiling mounted fan coil units providing both heating and cooling to each wing and lobby area of the 3 storey building. Core areas are now served with more efficient wall mounted electric panel heaters which are controlled locally.
Also upgraded was the roof mounted air handling unit which provided fresh air to all floors. The new AHU is fitted with a heat recuperator to recover heat from the air before being discharged to the atmosphere.
Over recent years the building had benefited from minor refurbishment, however to increase the efficiency of the building, light fittings were updated to flat LED panels, existing fire alarm devices and installation of new power supplies to new HVAC systems.
The domestic water cold water storage tank was past its useful life and was replaced with a new GRP tank, protected by trace heating along the route of the external pipework.
To eliminate clashes on site, main areas of the installation were drawn in 3D using AutoCAD Revit. This also provided the ability to do materials takeoff and for the client to view the proposed installation prior to work commencing.
Throughout the installation parts of the building were occupied and work had to be carried out in phases or out of hours.
