Do You Have an Energy Efficient Home?

 How do you know if you have an Energy Efficient Home?

Energy Efficient HousingThe simple answer is; take a look at your energy bill! And there are other things to consider…

Take two identical looking houses standing side-by-side in a suburban street. Both houses have four family members of similar ages. Both families have similar habits.

The cost of electricity and water for the family on the left is $3700 per year. The cost of electricity and water for the family on the right is $2500 per year.

Which house would you rather live in? Easy question to answer! Now here is a slightly more difficult question: If they were both for sale how would you know which one would be the better buy? Well, you would have to ask and here are some of the things you would query…

When thinking energy efficiency here are 5 basic things that you can look for in a house, or that you can apply to a new house to make it more energy efficient:

  1. Ceiling Insulation.

    Right now is an especially good time to be installing ceiling insulation with the Government offering free insulation to the value of $1600.  Go for a rating on your ceiling insulation of R2.5 or above.

  2. Wall Insulation.

    Proper wall insulation in the cavity of a brick veneer house will have an impact on both energy and noise. If you are looking at a new house then give this some consideration. Wall wrap or sisalation does provide some benefits but full external wall insualtion will make a difference. 

  3. Heat Pump Hot Water Systerm or Solar HWS.

    Government Rebates also apply to these two items and they will make a difference to your energy efficiency rating. 

  4. Energy Efficient Appliances.

    Do some research. There are many good products out there now that have a long term effect: ie. flouro lighting, efficient fridges, no stand-by power on TV, computer and stereo, etc. 

  5. Avoid ducted Air Conditioning.

    It’s a power killer. Use natural ventilation wherever possible and energy efficient ceiling fans. You use as much energy opening a window as you do looking for the A/C remote controller! The thing about climate is this: Humans adapt over time to various climates. If you continually use A/C systems then over time you will creep up the amount of usage and the push down the temp control. It’s a slippery slope and a couple of degrees can make a huge difference to your energy consumption. Where possible: resist. It is better for the environment and over time you will adapt.

It can really be that simple!

When someone comes knocking on your door in the near future offering you cheap Green Loans don’t pretend you are not home. Invite them in and listen. If you are looking at a new kit home, a project home or owner building a home in the future you will need to do your homework and research on energy efficiency measures. But it will be homework that will be well worth it.
