Summary

Pick Everard was asked by EDF Energy to upgrade and replace key systems within a three-storey building in Doxford. This included air handling plant (AHP), air distribution systems, VRF systems, lighting and the changeover of refrigerant from R22 to R407C.

The brief

We were commissioned to replace the entire ventilation plant and air distribution system, as well as install new lighting and ceilings. This took place in three phases, in an operational building.

The objective was to improve comfort and working conditions, as occupancy had significantly increased. It would also reduce the client’s energy and operational costs.

Our response

We designed and installed new systems allowing for phased replacement of old equipment, with increased capacity and efficiency. This included LED lighting and PIR occupancy control, making it easier to control the environment. We also provided night system commission witnessing and upgraded the building management system.

Key facts

  • We maximised fresh air control with a CO2 sensor.
  • We built a heat recovery and inverter drive into the AHP.
  • We provided LED lighting and PIR control, reducing energy use by 15%.
  • We incorporated BMS energy monitoring.
