Canolfan Rheidol - Public Architecture

28 Canolfan Rheidol
“The building was
required to achieve
a BREEAM
“Excellent” rating
and this was
achieved by a
mixture of passive
and active
measures.”
Cnec kinder boiler
9m wide full height atrium, allow the building to be
predominantly naturally ventilated when required.
The ground floor facilities contain the high
occupancy areas requiring mechanical ventilation,
whilst the upper floors have the highly serviced
cellular spaces grouped at either end of the open
plan wings.
• Thermal Mass: Exposed concrete soffits allow for
heat absorption during the day following night time
cooling by a BMS controlled high level windows.
• Heating and Hot Water: This is provided by an off
site biomass boiler, which burns locally sourced
woodchip. The Council also provides the adjoining
WAG office building with energy at 2p/kWH plus a
small service charge.
• Electricity: In addition to generous natural lighting,
internal luminaires incorporate fully controllable
daylight dimming, adjusting power consumption
in relation to daylight levels. A 15m high
“Quiet Revolution” wind turbine and solar panels
supplement electrical demand.
• Water Conservation and Biodiversity: Rainwater
harvesting is incorporated for toilet flushing.
