Eaves, trees and shading
Shading your house and outdoor living areas will dramatically reduce the heat you feel from the sun’s rays, improve your family’s comfort and save energy.
Direct sun can generate the same heat as a single bar radiator heater over each square metre of a surface. Shading can block up to 90% of this heat.
Eaves are essential for shading windows and walls outside your home and reduce the heat load entering the building.
Install a minimum of 600mm eaves, but 900mm eaves are even better as they give your walls more shading from the midday and early afternoon summer sun (often the hottest part of the day).
Consider placing trees and shrubs along outside walls to reduce the sun’s heat entering your home and lower the temperature naturally.
You can also use plants to trap and redirect cooling breezes into your home but be careful not to deflect breezes away from your house.
Use evergreen plants wherever you want permanent shading, such as on western-facing walls.
A pergola with a deciduous vine or appropriately angled louvres can provide shade in summer and let warming sun in during winter.
