Saving energy in our homes, means saving dollars and the environment

sustainable living by Energy Aspect Living
A recent report1 prepared by ClimateWorks Australia, an independent non-profit organisation, documents that every Australian home can use less energy, no matter its shape and size.

This might be something we already knew, however it is surprising how many household have not yet implemented some of the easiest actions to reduce energy use.

What’s even more surprising is that some of these things are overlooked when renovating or building a new home.

There are a number of different ways we can save energy in our existing homes which can also inform us for when it comes time to renovate or build. The following tables provide some insights.

Our behaviour

Our existing homes1

When renovating or building a new home

Standby power

We can actively switch off standby power of appliances to save up to $99 per year

We can ensure switches in each room make it easy and convenient to switch off standby power

Clothes drying

We can hang clothes on the clothes line instead of using a clothes dryer

We can consider a drying room or undercover outside space for drying of clothes in winter, eliminating the need for a clothes dryer

Temperature control

We can choose whether to use a heater or air conditioner and how long and often these appliances are used

We can make the most of solar passive design, and build a home that doesn’t need air conditioning and only minimal heating requirements


Fittings and Fixtures in our home

When renovating or building a new home

Lighting

Upgrade from incandescent lighting to compact fluorescent equivalents alone can results in savings of up to $133 per year

We can carefully plan lighting needs, and install what is needed, investing in energy efficient lighting which may include LED’s

Shower heads

Upgrade to a water efficient shower head can save $316 per year

We can carefully locate the hot water system and select water efficient fittings and fixtures

Temperature control

Where heating and/or air conditioning are needed, upgrade to efficient appliances to save $390 per year

By making the most of solar passive design we remove the need for air conditioning. 

 

We can also reduce reliance on heating which means a smaller more efficient appliance.

Insulation

Improving insulation within your home can save you money, simply by increasing ceiling insulation to R4.0, draught proofing doors and window seals, and fitting exhaust fans with dampers can save $306 per year

Insulating the ceiling is standard, along with external and internal walls. 

 

A well constructed home means there are less draughts. 

 

Good quality window coverings with pelmets will also assist.


Appliances in our home (when it comes time to upgrade)

Television

Investing in an energy efficient television can save around $149 per year

Designing a home with shared living space that is functional can mean enjoyment of television entertainment by all (rather than each having their own television in their own room)

Freezer

Upgrade of a freezer can also have positive cash flow results, with savings up to $67 per year

A ventilated fridge and freezer space can improve appliance efficiency

Hot water system

Upgrade to an efficient hot water system can save big dollars in running costs, up to $936 per year

It is important to carefully consider the location of a hot water system for improved efficiency
