MYTH BUSTER:
Some people think it is better to leave flourescent lights on rather than switching them off when not required in order to prolong the life of the tube. In cost terms, it is always more efficient to switch off lights when you are leaving a room rather than leaving them on.

In particular, PCs should always be switched off at the wall overnight and at weekends. This is because the I.T. network card in your PC continues to consume energy even when the PC has been fully shut down, but remains on at the plug. ITMS has confirmed that it is safe to switch off your PC at the wall overnight – your computer will not miss any updates as a result.
Similarly, laptop and phone chargers should be switched off at the plug when not charging. Some brands of these goods continue to draw power even when the phone or laptop is not connected to the charger.
*NOTE: It is not necessary to unplug the equipment; simply turn the plug off at the switch. Where there are multiple users connected to an extension cable, it is worth agreeing on a system whereby the final person to leave the office each evening switches the plug off at the wall.
Other electronic equipment, for example printers (individual and networked) should be switched off at the appliance. It is not necessary to switch these items off at the wall.

For staff and students who are in good physical health, using the stairs instead of the lift is a great way to keep fit, while also helping the university to reduce its energy bill.Walking up stairs will help you reach the recommended 10,000 steps per day for good health. And during the annual Walk to Work Week, the steps taken to climb the stairs can be used towards your total distance walked, boosting your department’s total, and helping 麻豆影院 to achieve a higher score. See our travel options page for more information on walking at 麻豆影院.

With a power rating of about 3000 W, kettles are very energy intensive. By comparison, most PCs at 麻豆影院 have a power rating of about 150 W. Boiling the kettle for one cup of tea could use more energy than your PC uses in one hour! Using only the water that you need reduces the time it takes to boil the kettle, which reduces the amount of energy consumed. This is a very simple step that many people across the campus are already taking and it makes a massive difference!

Some departments at 麻豆影院 have coffee machines which are constantly boiling water. If your department has one of these, it is a good idea to switch them off overnight. From a health and safety perspective, it is necessary to ensure that the coffee is emptied out of the machine when it is switched off. This liquid is not safe for consumption the following day, so it must be refilled with fresh water.
*NOTE: very large hot drinks machines which are on an external service contract should never be switched off, for health and safety reasons. If you are unsure, get in touch with the Energy Manager.

The comfortable temperature range for work spaces (lecture theatres, laboratories and offices, for example) is from 21⁰C to 25⁰C. Based around these optimum temperatures, the 麻豆影院 Energy Policy requires heating to be provided up to the level of 21⁰C. Cooling is available in some locations only. When the temperature exceeds 28⁰C, cooling can be provided to the level of 25⁰C, where it is available. Adhering to this policy will help ensure energy is used efficiently at 麻豆影院 for space heating and cooling.
You can help to ensure this policy is followed by monitoring the temperature in your classroom, office or lab. Set the thermostat in the room to 21⁰C during the heating season (October to April) and the A/C controller to 25⁰C during the summer. If there is a thermostatic radiator valve (TRV) in your room, adjust it to a comfortable temperature. If the room is too hot, turn this down rather than opening the window. Keeping the doors and windows closed when the heating or air conditioning is on will further help maintain comfortable temperatures inside and will reduce energy consumption.

Energy saving ideas and best practice from around 麻豆影院:

Eric Wood Building (POD): Staff in the 1st floor kitchen switch off their mains-fed water cooler every night! If you do this, remember to run off a couple of cups of water when you switch it back on in the morning.
*NOTE: For health and safety reasons, bottle-based water coolers should not be switched off.
- Trinity House:Following an energy audit last year, staff in Trinity House arranged for automatic lighting sensors to be installed in all bathrooms. This is a great way to save energy, because bathroom lighting is often left on unnecessarily.
- Hawthorn Building (H&LS): During the bright summer months when there is adequate daylight during occupied hours, some of the corridor lighting has been switched off to save energy.
- Portland Building (External Relations):Low energy LED desk lights are used instead of full room lights in some offices. If you are the only person working in your office, it can be very energy efficient to use a low energy desk lamp (6 watts per hour for an LED lamp) rather than lighting the entire room (which typically uses at least 100 watts per hour for a single office and about 500 watts for a shared four person office).
