At Ecomax Homes, we are proud to bring over 10 years of BASIX experience and more than 7 years of NatHERS assessment expertise across residential projects throughout Australia.
A premium 550m² residence in Wilton, NSW that achieved 7-Star NatHERS compliance through smart thermal zoning and performance-driven energy design.
This premium residential project in Wilton, NSW involved the design and energy assessment of a large-scale 550m² custom home featuring multiple living zones, expansive open-plan areas, and a combination of enclosed and semi-enclosed spaces.
Due to the size and complexity of the dwelling, achieving consistent thermal performance across all areas of the home required a carefully planned and performance-focused strategy.
The project was developed to meet strict Australian energy efficiency requirements while preserving the architectural vision and maintaining construction cost efficiency.

Unlike many residential energy compliance projects where glazing is the primary issue, this home presented a different challenge entirely—the overall building volume and internal heat distribution.
Large luxury homes often experience:
These issues can make achieving 7-Star NatHERS compliance particularly difficult, especially without relying on expensive upgrades such as full double glazing systems.
The client wanted to avoid unnecessary construction costs while still achieving a high-performance and future-ready home.
At Ecomax Homes, we approached the project with a performance-based methodology focused on thermal zoning and internal balance, rather than costly material substitutions.
Instead of depending heavily on premium glazing systems, we improved how the building functioned as an integrated thermal system.
A carefully designed zoning strategy was implemented to control how heat moved throughout the home.
This included:
This approach significantly enhanced comfort across all areas of the residence.
Additional insulation was introduced to high-impact transition areas, including:
These upgrades helped minimise unwanted heat transfer and improved overall thermal efficiency.
To stabilise temperatures between large open-plan spaces and different floor levels, we incorporated the Alpha flooring system.
Benefits included:
This solution played a key role in balancing heat distribution throughout the home.
Rather than increasing mechanical cooling loads, ceiling fans were strategically positioned in high-demand areas to improve airflow efficiency.
This helped:
Instead of applying shading uniformly across the entire home, we focused only on areas with the highest solar exposure.
This targeted strategy allowed us to:
To prevent localised overheating caused by direct sunlight, skylight diffusers were integrated into key areas of the design.
These systems helped:
The project successfully achieved:
Most importantly, the home achieved real-world performance outcomes—not just compliance targets on paper.
For large luxury homes, energy efficiency is not only about selecting better materials—it is about understanding how the entire building performs as a connected system.
By focusing on:
we delivered a high-performance result while keeping construction costs under control.
