QUALITY PROFESSIONAL ELECTRICAL SERVICE

Use natural lighting whenever possible.

Switch off unnecessary lights, i.e. lights in unoccupied areas.

Clean light fittings, diffusers, lamps, windows and skylights.

Check illuminance levels and reduce lamp wattage or de-lamp as appropriate.

Consider replacing incandescent lamps with higher efficiency fluorescent lamps.

Arrange for all light coloured surfaces to be regularly cleaned. This ensures that more light is reflected to the work area.

Replace fluorescent tubes that have dark patches at each end. (Old tubes use the same amount or a greater amount of electricity than new tubes whilst putting out less light.)

Consider changing cleaning services to normal office hours.

Close all unnecessary openings to the building.

Ensure doors and windows are adequately sealed.

Do not heat areas that are not used often.

Use thermostats and time switches where possible.

Consider the use of personal or localised heating, e.g. heated mats and infrared heaters.

Avoid fan heaters in large areas. The draught they create makes others cold.

Ensure that each heater can be easily turned off.

Clean heaters.

Endeavour to turn all heating off by the afternoon when it is warmer.

Set thermostats to the minimum comfort temperature, (NB excess temperatures tend to be corrected by opening windows and door thus further increasing energy wastage).

Check that the time-clock is set to ensure operation only when work area is occupied.

Check that all thermostats are correctly located and set to the minimum comfort temperature.

Clean air handler filters to minimise fan power consumption.

Clean heat exchanger fins to minimise compressor power consumption.

Do not use personal heaters with air conditioning.

Reduce hot water thermostat setting to the lowest temperature which is acceptable. Recommend 55 degrees centigrade.

If hot water is only used for hand washing set lower, e.g. 40 degrees centigrade.

Ensure that the hot water taps are firmly shut off after use.

Repair leaking hot water taps.

Consider blanket wrap for the hot water cylinder.

Use coldest air intake possible.

Repair all leaks. Consider shutting off long pipe runs if they are no longer used.

Determine and maintain the minimum pressure required for all operations.

Switch off when not in use.

Check compressed air use is correct for application. In some applications blowers could be used instead.

It may be possible to recover waste heat for other uses.

Turn off when not in use. Idling is expensive.

Check motor sizing is correct.

Ensure the building is insulated.

Reduce draughts by keeping doors and windows closed where possible.

Install PVC curtains on doors that have to be open.

The following is a guideline of standard illumination values of various work places.
 

The standard values listed above are based on the horizontal illumination (working surface) measured 0.85 m above floor level. The values specified for the various types of traffic ways in buildings refer to a height of 0.2 m above floor level.

 
EXAMPLES OF NATURALLY OCCURRING ILLUMINATION.

Sun in summer ......................................................... 100,000 Lux

Sun in winter ......................................................... 10,000 Lux

Dusk ......................................................... 100 – 3000 Lux

Full moon ......................................................... 0.2 Lux

 Light Meter: To analyse light levels our light meter is available on a weekly basis.

Below is a Comparison Table of the various types of lighting available. It compares lamp output, wattage consumed and lamp life.
