Procuring appliances

It is important when buying new equipment to ensure that it is energy efficient. to help with this the EU energy labelling system has been set up.

The EU energy label

The EU energy label rates products from A, (the most efficient) to G (the least efficient). For refrigeration the EU energy label goes up to A++. By law, the label must be shown on all refrigeration appliances, electric tumble dryers, washing machines, washer dryers, dishwashers, electric ovens, air conditioners, lamps and light bulb packaging.

Hot Water Urns

Hot water urns are provided in kitchen areas for people making hot beverages. Hot water is instantly available with no need to heat up from cold, and the units are more energy efficient than kettles.

MFD's Multi Function Devices

The University has installed a number of MFD's around the campus. As a result it is no longer necessary to have printers in individual rooms. A siginificant reduction in energy can be achieved by removing these printers as all the associated running and stand by power consumption will be eliminated.

Photocopiers

Basic Operation
Photocopiers can be switched off overnight and at weekends and will consume no energy.

Automatic Operation
When in general use photocopiers are set up to go into standby mode after a set period of not being in use.
For a small photocopier power consumption is typically reduced from 120W to 30W (~25%)
For a large photocopier power consumption is typically reduced from 1000W to 250W (~25%)
Note:
A photocopier left on overnight in standby will waste enough energy to produce over 1,500 photocopies.

Printers

Basic Operation
Printers can be switched off overnight and at weekends and will consume no energy.

Automatic Operation
When in general use printers are set up to go into standby mode after a set period of not being in use.
For a Laser printer power consumption is typically reduced from 110W to 30W (<30%)
For an Inkjet printer power is typically reduced from 60W to 20W (~33%)

Double Sided Printing

The EU Energy Star website shows that the embodied energy of producing a sheet of paper is 17Wh which is 50 times the energy of copying 1 sheet. further detail is available at:
