Residential Energy Efficiency Reports
At Green Choice Consulting, we provide expert advice and cost-effective solutions to ensure you meet the energy efficiency regulations in the National Construction Code. Our team of accredited assessors offers the following energy efficiency reports for residential projects:
A BASIX Certificate is mandatory for all developments in New South Wales (NSW) and will ensure that your development complies with the sustainability targets.
The Building Sustainability Index (BASIX) aims to minimise environmental impact by reducing potable water consumption, improving thermal comfort and reducing greenhouse gas emissions.
The BASIX standards apply to the following developments:
- New homes, dual occupancies, villas, townhouses, and multi-unit developments
- Renovations/extensions valued at $50,000 or more
- Large swimming pools and outdoor spas with a capacity of 40,000 litres or more

Our assessors will ensure your project complies with the water efficiency, thermal comfort, and energy targets to ensure compliance. Our expertise will ensure that your BASIX Certificate is accurate and reliable.
The Nationwide House Energy Rating Scheme (NatHERS) provides energy ratings for new dwellings and renovations. Our accredited NatHERS assessors can help you achieve a 6-star or 7-star rating to ensure your project meets the minimum energy efficiency requirements.
NatHERS uses computer simulations to rate homes from 0 to 10 stars, indicating their expected energy usage. Accredited software tools such as BERS Pro, FirstRate5, HERO or AccuRate are used to input data such as:
- Weather
- Occupancy
- Construction materials
- Insulation and glazing
- Colours
- Shading
- Compliance with national energy standards

We use accredited software to measure the performance of your home and provide an accurate energy efficiency assessment.
The NatHERS Whole-of-Home (WoH) assessment is a new requirement that generates a score based on appliances such as:
- Heating and cooling systems
- Hot water systems
- Stove and cooktop type
- Solar panels
- Battery storage
- Lighting
The WoH assessment is required for all new projects that are completed under NCC2022. Our team is fully trained and ready to help you meet the new NatHERS standards.
