Computers
Do you
leave your computer running at the end of the day because you do not want to
wait for it to boot up in the morning? Windows has an option that allows you to
place your computer in a temporary state of rest that can quickly be resumed to
full use and consumes less energy than leaving your computer running.
Adjusting Windows Power Options
- Go to Windows ‘Control Panel'
- Select ‘Power Options'
- We recommend that at the very least you set the screen to sleep after a defined (i.e. 10 minutes) of inactivity; this simply sets the screen to a very low power consumption mode, as long as no keys are pressed and the mouse remains inactive.
- Press any key or move the mouse to return to normal
Printers
Power Saving
Printers consume
power continually if they are left running, laser printers being the most
offending type as they need to keep their internal components warm ready to
print. Most printers have sleep mode
setting that after a definable period of time (i.e. 20 minutes) they will go into
a very low powered state. Once a print job is sent the printer will ‘wake’ up
quickly and start printing normally, the typical added delay is only 3 minutes.
Save Paper
Paper consumption is
a big issue for most offices but this can be reduced by adjusting the default
printer options to duplex (both sides). If this feature is available on your
printer you will find a duplex option in your printer settings.
Save Ink
Set your printer
settings to default to Mono (Black and White) to reduce the costs of expensive
colour inks and toners. Also use the ‘draft’ print quality setting to reduce
the amount of ink used. Both these options will also speed up print jobs
considerably. These settings can be manually overridden on each print job as
required.
Servers
Unused Equipment
Ensure any equipment
that is not being used is powered down fully but do not use any power saving
modes, other than turning screens off.
Virtualisation
‘Virtualisation’ is
a new concept whereby a small piece of software is installed on your server
which divides up your server resources i.e. CPU, memory and hard disk space,
installing multiple editions of Windows. This reduces the number of physical
servers required, e.g. 8 servers running at 20% capacity can be consolidated to
2 servers. Warning – never
consolidate all your servers to 1 virtualised server as if there is a hardware
issue, everything will be affected.
Temperature Control
Air Conditioning is
required in most server environments however it is worth checking the
temperature it is trying to maintain as this can be excessive and expensive. By
using a simple thermometer to check the temperature it is possible to decrease the
demand on you’re A/C, Google recommends 26.7C or 80F.
Monitors
Like
most modern technology, monitors should have built in power saving modes which
should be enabled and set to the desired levels.
