Hoval boilers boost Senedd’s sustainability
Three Hoval 600 kW gas-fired boilers are helping the National Academy for Wales minimise the energy costs and environmental impact of the award-winning Welsh Assembly building — the Senedd. Designed by the Richard Rogers Partnership, the Assembly building at Cardiff Bay includes a debating chamber for 60 members, office and meeting spaces, public spaces, private accommodation and catering.
These replacement boilers offer up to 92% net efficiency and low NOx emissions. They are highly insulated to reduce standing losses to around 0.3%. The design of these boilers also reduces the time required for maintenance.
Other features of the building include natural ventilation, extensive use of daylight, rainwater harvesting and ground source heat pumps. The building has a BREEAM ‘Excellent’ rating.
