building technology

Shrewsbury Environmental Technology Centre - The Pump House

Project Achievements:

BREEAM Assessment Rating: Excellent

Approximately 70% less co2 than a standard office building

Environmental Technologies included:

  • High insulation levels - Typically U value of circa 0.15W / m2 /C as opposed to building regulation requirements of circa 0.25W / m2 /C
  • Solar Photovoltaic panels with peak output of 7.7kw of electricity
  • Solar Evacuated Tubes for domestic hot water
  • Heat Recovery Ventilation systems and underground plenum
  • Rainwater collection for use in WC's
  • Waterless urinal and low flush WC's (4 litre flush vs standard of 6 litres)
  • Occupancy and light sensitive lighting controls
  • Biomass Pellet boiler with weather compensated heating controls
  • Energy Motoring System. All energy used is metered and charged to end users
  • Air tightness: Achieved a figure of 4.7 m3/ h / m2 against required level of 10

 Materials used:

  • Timber frame construction for new section using FSC timber
  • Insulation: Herakilth External Boarding, Warmcell and Celotex
  • External Render: St Asier Lime Render
  • Paints: Earthbone Natural Paints
  • Carpets: Made from recycled fibre

 Design features:

  • Existing buildings - High Thermal Mass - Heavy Construction
  • New buildings - Lightweight - Low Thermal Mass
  • Plenum at the base of the building to pre-heat / pre-cool incoming air for the ventilation system
  • Naturally ventilated with mechanical assistance
  • Centrally located for public transport, cycling and walking to work
