Ever wondered how hot your home gets in summer or how cold it is in winter?  Think solar is a good idea but not quite sure if it would work on your roof, or if it is worth investing in a rainwater tank?

Now you can do your own investigation to help you answer these questions, using the My Climate tool.

Council has mapped temperature difference across the city and has developed a tool that will help you understand daytime and night time temperatures for your home in summer and winter and compare it to other homes in your area.

If you are looking at investing in solar, My Climate  can also calculate the best size solar system for your home, together with electricity generation and payback periods.  You can also calculate how much rainwater your roof can capture to indicate what size tank you would need. My Climate will also help you to work out if you need better insulation in your ceiling.
