This new building for the Welsh Assembly Government is one of two in Aberystwyth using Oventrop valves to control heating and cooling.

Two new buildings in Aberystwyth both use Oventrop valves to control heating and cooling. One is for the Welsh Assembly Government. The other is the neighbouring offices of Ceredigion County Council. Hoare Lea was consulting engineer for both buildings, with different M&E contractors.

MITIE Engineering of Cardiff installed the services in the Welsh Assembly Government building, which include natural ventilation, grey water, solar hot water and ammonia chillers serving a major IT server room.

CMB Engineering of Cardiff was responsible for the Ceredigion offices, with mixed-mode venti­lation, grey-water recycling systems, solar hot water and biomass district-heating systems.

The main heat source is MTHW generated by a 1650 kW wood-fired boiler, with a 1200 kW gas boiler for backup. The boiler delivers hot water to a heavily insulated 25 000 l accumulator vessel to provide a consistent load.

MTHW is pumped underground to the buildings 150 m away, where heat exchangers provide LPHW for heating and generating hot water. Some of the valves for LPHW distribution were supplied by Oventrop. They include bronze and cast-iron commissioning valves, low- and medium-flow commissioning sets, bronze and cast-iron double-regulating valves, isolation valves, strainers, drain cocks and metering stations.

Aquastrom T Plus multifunction DHW secondary regulating valves were chosen for the DHW systems in both buildings.

CMB also installed Oventrop TRVs with matching lockshield valves on the radiators in the Ceredigion offices. These TRVs have 2 m remote capillary thermostats. DHW temperatures are controlled by Brawamix thermostatic mixing valves.
