What do we mean by ‘energy efficient’?
An energy-efficient home uses less energy while maintaining year-round comfort. This includes considerate heating, cooling, ventilation, insulation, and airtight management, so your home needs less power to perform well.Â
Energy efficiency isn’t just about adding technology; it’s about building and designing to prevent wasted energy. Thoughtful orientation, high-performance materials, and efficient systems all play a vital role.

4 energy-efficient methods to try
Â
Consider build location and orientation.
Where and how your home sits on the block greatly impacts its energy performance. By aligning living spaces to capture natural sunlight, you can reduce the need for artificial heating in winter. Shading, eaves, or trees help keep the home cooler in summer.
Even decisions, like window placement or positioning outdoor areas, can make a noticeable difference. Thoughtful orientation works with the environment rather than against it, using less energy daily.

Factor in high-quality insulation.
Insulation supports an energy-efficient home by aiding cooling in the summer and warmth in the winter. Insulation traps air, preventing warm air from leaving your home, keeping it toasty in the colder months, and preventing hot air from entering the warmer months.
This reduces your overall energy bill and greenhouse gas emissions. When planning your new home build, it’s worth exploring insulation options and finding the best type for your property and location.
Invest in energy-efficient appliances and lighting.
There are plenty of options on the market to help you maximise your energy-efficient home. To start with, look for appliances with a higher energy efficiency rating. This runs for one to six stars, with more stars indicating a more efficient appliance.
Energy-efficient lighting is another easy way to reduce your energy costs. LED bulbs are a great option as they’re more efficient and tend to last longer than halogen bulbs, meaning you’ll replace them less.
Work with the right builder.
Working with a builder who understands what creating an energy-efficient home means and why it’s important can make a significant difference.
At IMSU, our expert team will work with you to find the best options to support your energy-efficient home goals. Through theIMSU Impact Initiative, each project becomes a platform for social and environmental contribution.
Every scan, payment, build, or sponsorship is one step in a larger system of intentional good. Whether through supporting national charities such as Cancer Council, Variety and Animal Welfare League NSW, connecting with the community or donating saved printing costs to Carbon Positive Australia, we’re always looking for ways to do more.
