An energy-efficient house uses less energy compared to traditional houses. This type of eco-friendly home will help you save on electricity bills, and live in a comfortable and healthy environment. Not to mention will help you achieve a minimum of 6-star energy rating (in Australian standard).
A star energy rating is the rating standard of a house’s thermal energy performance. A six-star rated house ensures that your utility bills will be lower than usual while keeping your home environment-friendly. A higher star rating (up to 10) means more energy-efficient living space.
Features of an energy-efficient home
Whether new or old, most energy efficient homes possess the following features:
1. Solar panels
Solar panels are one of the best features of most energy-efficient homes. Solar panels can convert the sunlight into direct electricity, reducing your dependency on fossil fuels. This can also lower your energy costs.
2. Eco-friendly materials
An energy-efficient home should be made up of eco-friendly materials. Eco-friendly materials need less energy to be produced in the first place. Moreover, they help to keep the environment clean and green.
3. Proper insulation
Insulation is a must-have feature for a quieter, comfortable, and energy-efficient home. The right balance of insulation can trap the heat in your home. It means you don’t need to pay extra for the heating system. There are certain types of insulation systems designed for some particular areas and homes. Homeowners can also choose from different types of insulation systems for their homes depending on their location and age of their house.
