GOOD ENERGY MAKES THINGS BRIGHTER FOR EVERYONE

Our low-cost spring energy actions

switch-off-lights Did you know that lighting can burn up to 50% of an office energy bill? Did you know it’s a myth that it’s better to leave lights on when you leave a room? The instant way to cut your energy costs is to turn them off when they’re not needed – make posters and stickers to encourage co-workers to switch lights off in un-used areas.
hay-new3 Clear bulky furniture away from windows, clear the grime off the glass, roll up the blinds and let the sun shine in to your workplace! Natural light lets you switch off your fluorescent lighting and can save you a bomb. Sunshine also improves mental health and work performance. Embrace spring and welcome the sun into your work.
de-lamp In lights with double fluorescent tubes, you may be able to remove the second tube in areas where strong light isn’t needed. This is called ‘de-lamping’. It’s cheap to do, it can almost halve the energy use in each fitting and can save your workplace a bundle! Use our calculator below to estimate how much you could save!

INVOLVING YOUR WORKPLACE

Calculate what you could save by de-lamping your work environment

TRY OUR DE-LAMPING CALCULATOR

A quick tool to gauge your
dollar saving potential

You could potentially save $$$ by not over-lighting your workplace - for a very small investment. Estimate your savings from de-lamping!

How much do you pay for electricity?

Use the default figure for a general estimate.

HINT BACK

For a quick and easy estimate of your electricity cost, divide the total dollar amount (excluding GST) of a recent bill by the total number of kilowatt-hours (kWh) used over the billing period.

How many hours per day are your lights burning?

We only need ball park figures.

BACK
When you turn the lights on do they flicker or start smoothly?

Check when lights have been OFF for at least 10 minutes

How many twin fittings do you think could be de-lamped?

HINT BACK

De-lamping opportunities can often be found in corridors, bathrooms, waiting rooms, meeting rooms. In open plan offices, good candidates could be fixtures around the perimeter of the ceiling perimeters, or fittings above open areas that are free of desks or work stations. You might also be able to reduce light levels in fittings that are next to windows or areas with high levels of natural light. When you are ready to de-lamp, it's worth buying or borrowing a lux meter to compare your lighting levels against the Australian Standard for workplaces (find out how at the end of this calculator).

Assumptions start over

Fluoro lighting comes in many shapes and sizes and can be hard to tell apart. We've had to make a few assumptions so you can use this calculator easily. We assumed your fluorescent lighting is the most common type for old buildings (T8 type), with a lamp power of 36W per lamp. We assumed your lamp ballast would be losing 7W if it's magnetic (flickering), and 2W if it's electronic (smooth). This calculator gives you a rough estimate of your savings - energy auditors can be engaged for a more accurate assessment of your lighting type and savings.

REMOVE ALL INCANDESCENT GLOBES

Incandescent light globes use almost five times the energy used in compact fluorescent lamps (CFLs) and LED lamps.

DE-LAMP QUIET CORNERS

If your office has 1 light switch for the whole floor and there are areas that are unoccupied, then take the lamps out of the fittings that are lighting unused areas.

AUTOMATIC SWITCH-OFF

Install timer switches to automatically switch lights off at a particular time, or after a length of time to reduce reliance on staff to turn off lights.

INSTALL SENSORS

Install motion sensors in rooms that are occupied intermittently (such as bathrooms, store rooms, printer rooms). This can be cost-effective if extensive rewiring is not required

COST A RETROFIT

Next time an electrician visits your workplace, get them to quote for retrofitting old lighting with energy efficiency fittings (for example fluorescents or LEDs).

BRIGHTEN AND WHITEN

Reflected light makes a huge difference – next time you paint your office use light colours so that you can reduce your reliance on artificial lighting.

EMBRACE WILD ENERGY

For refurbishments, consider skylights, solar tybes or glass partitioning for more natural light and less reliance on electrical lighting.
