Ability Projects Fan Coil Units Installed in New Welsh Assembly Regional Office


A key environmental feature of the new £20 million state of the art Aberystwyth Regional Office of the Welsh Assembly is the inclusion of Matrix I EC-DC cooling only fan coil units manufactured by Ability Projects Ltd, Wimborne, Dorset.

Opened late last year by the Rt Hon Rhodri Morgan, First Minister for Wales, the building comprises 7,700 m2 of open plan office accommodation with meeting rooms and break out spaces etc on 1st, 2nd and 3rd floor levels with plus ground floor public area and staff restaurant and is designed to achieve a BREEAM ‘Excellent’ rating.

The Ability Matrix fan coil system is unique in the UK in providing infinitely variable speed control of the entire fan coil unit as well as each fan within it, enabling each air duct to be balanced for air volume through fan speed alone, thus removing the need for costly, noisy volume control dampers and their time consuming installation. Matrix I fan coils are also designed to adjust the overall air volume according to room occupancy, thermal demand or a combination of the two.

The fan coil units were selected to meet NR31 standards and were supplied complete with Trend IQ212 controllers with sensor and remote sensor setpoints supplied and fitted by third party on site. Fan coil unit capacities vary between 0.71 and 3.37kW against an environment 0f 30 Pa Pascals resistance. Other engineering services, installed by Mitie engineering Services, Cardiff, include natural ventilation, biomass boiler, solar panels, briese soleil natural shading and intelligent lighting controls.
