Designing your house sustainably will reduce your energy bill for many years to come, saving you money and benefiting our environment.
- Double glazed windows provide a thin layer of insulation between glass panels which has the effect of reducing heat transfer into the home. In summer this reduces heat entering the house, and in winter this has the opposite effect by reducing heat leaving the house.
- Installing insulation can save up to 45-55% on your heating and cooling costs. Uninsulated ceilings, walls and floors can account for 70% of total heat loss from a home.
- Choosing the right building materials for your home that are sustainably sourced can both reduce your environmental impact and provide passive benefits such as heating, cooling and lighting. Contact the City's Sustainability Officer on 9021 9600 for more information.
- Installing a solar photovoltaic (PV) systems can substantiall reduce your consumption of electricity from the grid, reducing your power bill. A 1.5kW system can reduce your consumption of grid electricity by up to 40%.
- Installing a standard 2,000 litre rainwater tank can save up to 26,000 litres of water each year for use on your garden. All rainwater tanks require connection to a bubble up pit and any rainwater tanks over 5,000 litres require a building permit.
- Effective shading, which can include eaves, window awnings, shutters, pergolas and plantings can block up to 90% of the direct heat entering your house from the sun.
- Incorporating Water Sensitive Urban Design (WSUD) which can include permeable paving, garden beds designed for infiltration, and landscape features (e.g. swales and soakwells) that increase percolation into the soil can reduce your impacts on the environment
Making small changes in your home can add up to big changes in your energy and water use
- Installing energy efficient LED lights can save over 50% of electricity consumption compared to current energy efficient Compact Fluorescent Lamps (CFLs). Lower Watts means lower energy use.
- Cooling your home to 23 degrees in summer and heating it to 19 degrees in winter will save you considerable amounts of money and electricity. Every degree above 19 degrees in winter and every degree below 23 degrees in summer can add up to 10% to the running cost of your heater/air conditioner.
- Purchasing energy efficient applicances with a higher 'star rating' can save you a signiciant amount of energy and money over the life of the appliance.
- Turning appliances off at the wall when not in use can save you up to 10% of your electricity costs.
- Installing water saving shower heads and tap fittings can save up to half of the water used by older fittings
- Putting a timer in your shower and limiting your showers to 4 minutes will save considerable amounts of water. Every minute you reduce your shower by will save between 9 and 20 litres of water depending on your shower head
- Washing with a full load can reduce the number of loads you need to do. One load of washing uses approximately 120 litres of water. Cold washes can also add to your energy savings.
A waterwise garden can reduce your water use, and contribute to the overall biodiversity of the City.
- Planting native plant species will reduce the amount of water your garden needs to thrive. It will also help support local native wildlife by providing them with suitable food and habitats
- Mulching your garden will not only mean your garden requires less water, but it will also help prevent weeds and make your garden more productive
- Creating a waterwise verge garden is a great way to reduce your water consumption. A waterwise verge requires much less time and maintenance than a verge lawn and if mulched correctly, won’t need to be weeded anywhere near as much. Converting a verge lawn into a waterwise verge garden is not difficult or expensive. Contact the City of Kalgoorlie-Boulder to find out how on 9021 9600
