To help reduce CO2 emissions, PWN has prioritised the Trias Energetica as follows:

  • Reduce energy consumption and prevent greenhouse gas emissions
  • Use sustainable sources of energy
  • Compensate

The first step – reducing energy consumption – was taken by performing energy scans. These energy scans provide insight into the current levels of energy consumption at the various locations and the potential for saving natural gas, electricity and fuel. By following MWH’s recommendation, the demand for energy will actually fall in the period ahead.

    Location: Velserbroek, Netherlands
    Status: Complete
    The automated production of drinking water means that most utilities buildings are now unmanned. The energy scan revealed that the necessary quick wins can still be achieved from the utilities buildings. Savings can be made in natural gas and electricity consumption by adjusting the controls of heating and air-conditioning systems to recommended settings and switching off various electrical installations.

    Since the pumps by far consume most of the electricity, considerable savings can probably be made in this area. MWH therefore recommended that more attention be paid to the maintenance and efficiency of the pumps. An inspection of the pumps and measurement of their performance provided insight into their operation and efficiency to help determine the relevant energy-saving measures.

    MWH’s recommendations for the office locations included using presence detection and lighting control according to the availability of natural daylight, renovation of the old office building, adjusting the heating controls and good housekeeping by employees.

    Discrepancies can be detected at an earlier stage by recording and analysing energy consumption, and this moreover helps to keep a better check on the energy invoices. On the recommendation of MWH, PWN plans to increase its energy management efforts in the years ahead.

    Lastly, in consultation with the fleet manager, PWN is looking into the potential for enhancing the sustainability of its vehicle fleet. Aspects include energy-efficient vehicles or alternative fuel use.

    Due in part to MWH’s study, PWN has drawn up an action plan for the coming years. PWN has translated its ambitions in the plan into three objectives:

    • Climate-neutral business operations in 2015, in other words greenhouse gas emissions (expressed in CO2 equivalents) to equal zero;
    • The implementation of energy-saving measures across the company, including measures arising from the MWH energy scans;
    • To generate its own sustainable energy, the potential for which has been identified by the energy scans.
    • Energy consumption analyses
    • Performing energy audits
    • Assessing the relevant energy-saving measures
    • Calculating the relevant energy-saving measures
    • Energy scan reporting
    • Project presentation
    • Quick wins for the utilities’ buildings
    • Optimisation of pump installations
    • Various energy-saving measures for the office buildings
    • Energy monitoring
    • Energy management
    • Enhance the sustainability of the vehicle fleet
