Did you know?

  • Rooms with a lot of low voltage halogen downlights chew up electricity - low voltage doesn't mean low energy!
  • If you're happy to replace the whole system, ask your electrician for compact fluorescent or light emitting diode (LED) downlights, or see Choosing appliances & lighting for other options.
  • Recessed downlights are like having holes in your ceiling. They let a lot of heat escape in winter.
  • But now you can buy isolators that sit over the fitting above the ceiling and reduce the air flow and the fire hazard.
Thinking through your needs

Assessing your home

Save money

Look around for opportunities to save money.

Do you really need to extend out or up, or do you just need to re-design your interiors for better use of space?

If you plan to demolish sections of the house, are there building materials like windows, doors, floorboards or interior fittings that you can reuse elsewhere, sell or even give away?
[See Your Home: Energy use; Water use.]

Look for opportunities to lock in ongoing cost savings too! To save on energy and water bills, find out where you're using more than you need to - check your current bills and see the tips on the opposite page or visit the NABERS website.

In some locations there are companies who can come to your home and do a professional water and energy assessment to identify the best ways for you to save on bills. As well as saving money you'll be helping the environment.

Improve comfort

Make a note of rooms that are too hot or too cold at different times. A few simple design improvements could make the world of difference to your comfort. If you use a lot of heating or cooling to stay comfortable, your renovation is a chance to ensure lifetime savings on bills.

'Getting a water and energy assessment was the best thing we ever did. It saved us much more than it cost us!'

Take the opportunity to insulate walls and double glaze windows.

Many older homes are draughty. Add draughtproofing strips to doors and windows and check that new windows and doors have good seals. Fit dampers to chimneys and flues to block air leaks.
[See Your Home: Passive Design.]

Now's your chance to fix up problems like dust, damp and mould.

Look for opportunities to make your home safer and easier to move around in for occupants and visitors of all ages and abilities.

Be prepared

If you see warning signs that may indicate structural problems or other hazards, seek professional advice from an architect, engineer or builder. Signs could include:

Pre-1970s homes are likely to have lead-based paint so if you're removing it follow the advice in the Six step guide to painting your home (www.environment.gov.au).

Homes built pre-1990 may contain asbestos. It's commonly found under eaves, but may also be found as roofing, wall linings and cladding.

If you suspect you have asbestos contact your local council or state health and environment authorities for more information. Removal is not always recommended, but if it is removed, it needs to be done by a specialist. Asbestos removal contractors are listed in the Yellow Pages.

Kim's home assessment revealed some big opportunities. After installing a 3-star showerhead and new ceiling insulation, and turning off the second fridge, the improvements were obvious.

Vegetable dye in the cistern will make toilet leaks easier to spot - or turn off the tap to the toilet and see if the water in the cistern disappears.Leaks to be fixed:
