Green 50: How to Save

People are the key to success when it comes to ‘Going Green’. Establishing a ‘green team’ that includes both staff and management, is a great way to get the best results from your green practices and an action plan for energy, water and waste management.

Set out clear actions, the date you wish to achieve them by and who will take charge of completing the task.

Awareness of this action plan and the company’s goal to donate a certain amount to its charity of choice is vitally important to generating support and participation among the entire team.

Staff should be encouraged to provide suggestions on possible improvement options and they should be made aware of the improvements and savings that are being made throughout the company’s participation in the Green 50 initiative.


  • Compressed air leaking through a single 3mm hole
    could cost you €700 a year.

  • A faulty toilet can cost as much as €1000 a year from
    leaking water if not fixed, while a new ball cock will
    cost you no more than €15.

  • A tap left on can use as much as 500 litres an hour.
    This can cost you up to €9,000 a year.

  • A urinal will use about €500 of water per annum,
    if not controlled with sensors. Modern urinals don’t
    use water.

  • A halogen bulb only converts 20% of electricity used
    into light. The other 80% is wasted as heat. The reverse
    is the case for LED lights.

  • A halogen bulb will last for 2000 hours. An LED bulb will
    last 20 times longer, meaning LEDs cost less in
    the long run.

  • A hot water tap left running unnecessarily for 5 minutes
    in every hour of a working day will cost your business
    €6,000. Turn off taps when not in use.

  • Every tonne of food waste that your business throws
    away costs you about €5,000 in the cost of food
    purchase, cooking and disposal.

  • Food waste is a real problem and it is costing Irish
    householders €700 each year.

  • Equipment left on ‘Standby’ accounts for up to 10% of
    total energy consumption worldwide. Power off
    equipment when not in use.

  • If everyone boiled only the water they needed to make
    a cup of tea instead of filling the kettle every time, we
    could save enough electricity in a year to run nearly half
    of the street lighting in the country.

Case study: Stillorgan Village Centre
