Switch off, power down and conserve energy.
Night Audits have revealed that thousands of dollars worth of electricity is wasted annually because of staff and students not turning off computers, lights and other electrical devices.
By improving energy efficiency of our campuses, we can:
- help reduce the University's greenhouse gas emissions;
- extend the working life of equipment;
- reduce electricity bills;
- reduce maintenance costs; and
- gain recognition for our environmental leadership.
Start by looking at the settings on your computer to ensure it is not expending unnecessary energy.
- From the Start menu: Control Panel - Personalisation - Screen Saver - adjust the 'Wait' to 5-10 minutes
- In the same screen: Change power settings - Show additional plans - choose 'Power Saver' mode
- At the bottom of the screen: Adjust the screen brightness by moving the cursor back to an appropriate level for your eyes - Close the window - APPLY - OK
- What You Can Do
- Switch lights off if you go out for a meeting or lunch, and at night. Contact us for 'Switch it off' stickers to prompt staff.
- Use natural light where possible, it's better for your eyes and will make your workplace more comfortable.
- Turn off your computer and other devices at the wall when you are not using them. Many electrical items spend most of the day unused but draw standby power.
- Use networked communal printers rather than individual desk-top printers; it is more economical, energy efficient and encourages important social interaction.
- Send your monitor to sleep. Monitors are responsible for more than one third of a computer's energy consumption, so conserve energy by putting yours to sleep or powering off altogether when you're away from your desk for more than 10 minutes.
- Assess if lighting levels are correct for the activity in the room. Investigate opportunities to remove tubes depending on required light levels.
- Open windows to cool rooms with natural air flow instead of using appliances like fans or air conditioning
- Use the air conditioner sparingly; set the air conditioner thermostat to 24-26 degrees in summer and 19-21 degrees in winter
- Keep lab doors and external windows closed so the air conditioner does not need to work harder than necessary.
- Set automatic timers on electrical equipment often left on stand-by overnight.
- Check the efficiency of old plug-in lab equipment using an energy meter. Review the readings with the manufacturers specifications to see whether the device is working as efficiently as possible.
- Wear appropriate clothing to reduce the need for air conditioning.
- Unplug kitchen appliances when not in use and turn the power off at the wall.
- Switch off electric hot water boilers at the end of the day.
- Turn the photocopier off at the power point over weekends and holidays or install a timer so you don't forget.
- Use energy efficient light globes.
- Only boil the necessary water for your coffee cup, not the whole kettle.
Lead By Example
If you are persistently struggling to get traction with colleagues switching off computers and monitors in your area, try using the following responses:
“It takes too long to boot up in the morning.”
Switch it on, then put your lunch in the fridge or make a cup of tea. Computers only takes a few minutes to boot up.
“IT might be trying to update software overnight.”
Computer updates occur when the hard drive is booted up, so by switching off at night and rebooting in the morning, you can ensure that updates will come through and your computer will run faster.
“Turning a computer on and off ruins the device.”
A computer is far more likely to wear out through overheating due to being left on 24 hours a day, than through the process of daily rebooting.
