Energy Saving Tips

At Home

  • When buying new appliances, be sure to purchase energy-efficient models with as many stars as possible.
  • Set the air-conditioner thermostat at 24 degrees or higher, in summer and at 21 degrees or lower in winter.
  • If your old air conditioner is on its way out replace it with a split system inverter unit with as many stars in its energy-efficiency rating as possible.
  • Use compact fluorescent bulbs or LED’s. You can lower your lighting bill by converting to energy-efficient low-wattage compact fluorescent or LED lighting and fixtures. The light generated by modern versions is very acceptable. If you have lots of 12 volt halogen lights (as was the fashion a few years ago), you are burning way more electricity than you need to and adding significant heat loads to your house
  • Consider replacing windows with double glazed versions.
  • Clean or replace heater and air-conditioner filters regularly, following manufacturer’s instructions.
  • Set the water heater thermostat at 60 degrees or “normal.”
  • If your hot water is heated by renewable energy make sure your dishwasher and washing machine are using this rather than letting them heat their own water. Even using hot water from your off peak electric system will be more efficient and cost effective than letting these appliances heat their own.
  • Wash only full loads in a dishwasher and use the shortest cycle that will get your dishes clean. Experiment with different detergents to find one that will work effectively for you
  • Fix defective plumbing or dripping taps. A single dripping hot water tap can waste over 1000 litres of water a month. That not only increases water bills, but also increases the gas or electric bill for heating the water.
  • Defrost refrigerators and freezers before ice becomes more than 10 mm thick.
  • Install shades, awnings or sunscreens on windows facing north and/or west to block the hot summer sun. In winter, open shades on sunny days to help warm rooms.
  • Close the damper when the fireplace is not being used. Try not to use the fireplace and central heating system at the same time.
  • Install an electricity monitor in your home. Locating the display in a high traffic area like the kitchen, creates awareness amongst all the occupants of just how much juice the house is using. Being able to measure the effects of changes instantly is a positive motivator.

At Work

  • Use energy-efficient equipment.
  • Keep appliances, equipment and fittings in good working order.
  • Switch off appliances when they are not in use! Leaving appliances switched on when they’re not being used is the most common cause of unnecessarily high electricity bills.
  • Educate your staff to use energy wisely.
  • Create reminders around the office to ensure your that staff get into the habit of being energy wise.
  • Reduce settings of appliances and lighting levels where appropriate.
  • When heating or cooling, ensure thermostats are adjusted to the correct temperature
  • Install CFL/ led/ energy efficient lighting
