Refurbishment works were undertaken to the first floor of the Virginia Woolf building, including changes in layout. As part of the works, we stripped out and replaced existing services with VRV heat recovery air conditioning systems, providing heating and cooling. Various works were also carried out on the ground and second floors. Works were split into phases and included ‘out of hours’ working.
Supply & installation of: • VRV heat recovery air conditioning systems: o 6no VRV condenser units; o 26no fan coil units (FCU’s); • New secondary supply and return ductwork to suit FCU’s and associated grilles and plenums, including slot diffusers along external perimeter spaces in some areas; • I-Touch Manager centralised controller & local controllers for all FCU’s; • In various areas, each FCU was linked to new micro-switches on external windows which switched off the local unit in the event of the window opening; • Fresh air supply to internal meeting rooms via a soffit mounted MVHR unit, providing supply & extract air with an electric heater battery; • New extract for kitchenette area and for ground floor;
