At Energy Rating Perth, we aim to provide clients with every probable solution to help improve the thermal performance of their homes. A large number of clients at Energy Rating Perth might not recognise the importance of landscaping and the ability of your home to achieve thermal comfort. Trees can provide shading on the walls and windows, which can greatly improve the interior thermal comfort. However, just like the concept of eaves, we may not require shading on all sides all around the year. For this reason, deciduous trees can be planted towards the northern side so in the winters, they can allow full sunlight penetration while evergreen trees are preferable for the eastern and western facades. This can help in keeping your home cool in the hot summers by providing shade and avoid unnecessary solar heat gain. In colder climates, trees can also limit the harsh cold air from penetrating into the building by acting as a barrier. In hot/humid or even moderate climates, this may be a limiting factor therefore, when choosing trees, they should be ones that allow air movement through the foliage.
Other than trees, there are smaller shrubs that are strategically placed can also cool the breeze before it enters into the building through evapotranspiration. Other landscape features water bodies also help in creating a cooling effect due to evaporation. The process can be speeded up by using a water spray in a fountain particularly into a summer breeze path. This is not recommended for climates with high humidity throughout the air as it may actually increase the humidity thus affecting the overall thermal comfort of the home.
Our energy assessors take into account a range of information when they are completing a 6 star energy rating assessment and may at times give recommendations that seem trivial but can add greatly to the energy efficiency of your home. Strategic selection as well as plantation of vegetation should be considered as a solution and site featured trees should be preserved rather than removed.
