Hot Water

Solar Hot Water Split System
  • Install water saving shower rose and tap aerators to save over 50% on hot water.
  • Try to limit showers to 4 minutes to save on hot water.
  • Fix any water leaks promptly. They can add 20000 litres per year to your usage.
  • Work out how much hot water you use per year and see if solar hot water is cost effective.
  • Other hot water alternative include electric heat pump or gas hot water systems.

Cooling

  • Insulation can control up to 60% of heat transfer in and out of your house. This can reduce household temperatures by 8 to 12 degrees C. Insulation Examples.
  • Window tinting can reduce solar radiation by 80%. This can reduce the sun's heat entering your premises.
  • Power roof ventilation can reduce roof loft temperature by 5 degrees Celsius. Lowering the loft temperature help reduce heat transfer into your house. Example.
  • Roof solar barrier paint can reduce building temperatures. This is easier to apply especially on flat roofs compared to bulk insulation.
  • Use natural breezes and fans instead of air conditioners where possible. Air conditioners can be assisted with fans for air circulation and heat removal.
  • External water bodies can assist in cool breezes.
  • External shading or landscaping can reduce cooling requirements. By preventing the sun's heat striking the building helps keep a building cooler.
  • Clean air conditioner filters to improve efficiency.
  • Consider running bedroom air conditioners on off peak electricity. This could save $100s per year. Most hours spent in a bedroom are off peak times where the power tariff is for example 1/3 less cost than the full time power tariff.
  • Reducing general electrical consumption can also lower cooling requirements.
  • Geothermal heat pumps uses the stable temperatures deep in the ground to control the house temperature. Geothermal Heat Pump Example
  • Use schedule or countdown timers to control energy consumption.
  • Passive Cooling House design principles.
  • Best Air Conditioning Energy Star rating for cooling and heating

Entertainment

  • Hifi equipment with switched mode power supplies and neodymium magnet speakers are far more efficient electrically. Advanced speaker case design helps with efficiency.
  • Consider placing a rooms entertainment equipment on one power board and switching it off at the wall when not in use.
  • Appliances can be controlled by remote controlled power boards if power point access is difficult.
  • Adjust the brightness of TV's to suit the environment. Full brightness often set as the manufacturers default will use more energy.
  • Turn off gaming consoles at the wall when not in use and save up to $200 per year. PS 3 and Xbox 360 have high standby power consumption.

Computers

  • Turn on computer power management with screen power down at 15 minutes and computer sleep in 30 minutes of inactivity.
  • Control computer peripherals with a single power board turned off at the wall when not in use. USB controlled power boards are also available that are only on when the computer is on.
  • Choose a laptop instead of a desktop and save over 50% in energy costs. Also consider desktops with energy efficient processors (often in small cases).
  • For light computing needs consider a Chromebook. This looks like a laptop, uses cloud (Google) computing resources and uses about 15 watts.
  • Buy computers with Energy Star 4 or 5 rating and include 80 Plus standard power supplies (> 80% efficient).
  • For business groups consider thin client computers with a server (local or remote). This will save energy and avoid PC replacement cycles.
  • Adjust the monitor brightness lower to suit the environment and also save electricity.

Timers

  • Consider daily, weekly, countdown timers or sensors to limit lighting hours.
  • Run a timer on a pool pump and save approximately $1000 per year.
  • Countdown timers can be used for classrooms, stairways, walkways, exhaust fans etc.
  • Any device with a moderate standby power consumption may benefit from a timer.
