Grundfos pumps contribute to energy efficiency for the National Assembly of Wales

Contributing to the energy-efficient operation of services in the National Assembly of Wales, recently opened by the Queen, are 24 Grundfos TPE electronically speed-controlled pumps.
Contributing to the energy-efficient operation of the National Assembly for Wales is a wide range of variable-speed pumps, pressurisation units and booster sets supplied by Grundfos. It is expected that the wide range of energy-efficiency features in this 5000 m2 building will nearly halve consumption compared with current best practice for office buildings – 75 kWh/m2 per year compared with 130 kWh/m2 per year. The £67 million building is designed to make maximum use of renewable energy sources, along with natural and passive systems for heating and cooling. The TP ranges of inline centrifugal pumps are at the heart of operations in the building. Grundfos supplied 24 TP pumps. All but one are from the TPE series of electronically speed-controlled pumps that offer energy savings of 30 to 50% compared to their fixed-speed counterparts. They serve hot- and chilled-water circuits and also provide the underfloor heating. Grundfos also provided the pump for the grey-water system serving toilets and providing water for washing windows. This water is collected from the roof. Grundfos worked on this project with consultants BDSP of London, contractor MJN Colston of Bristol and supplied the pumps via BSS in Bristol and Cardiff.
