Building a New Home?
NatHERS assessments play an important role in demonstrating residential energy efficiency compliance under the National Construction Code.
For new homes, NatHERS provides more than a rating. It helps project teams understand how orientation, glazing, insulation, shading, ventilation and construction materials influence thermal comfort and long-term energy performance.
Considering NatHERS and Whole of Home requirements early in the design process can help reduce redesign risk, improve project certainty and support more informed decisions before plans are finalised.
Why NatHERS Matters for New Homes
A NatHERS assessment measures how effectively a home maintains comfortable indoor temperatures throughout the year, helping demonstrate compliance with residential energy efficiency requirements.
For new homes, this assessment can influence key design decisions including glazing selection, insulation levels, shading, roof colour, ventilation and building orientation.
When considered early, NatHERS modelling can help identify practical opportunities to improve thermal performance, reduce energy demand and avoid costly compliance changes later in the approval process.
NatHERS & Whole of Home Requirements
Modern residential energy compliance extends beyond thermal performance alone.
In addition to the NatHERS thermal rating, many new homes must consider Whole of Home energy performance under the National Construction Code. Whole of Home looks at the energy used by household systems and appliances, including heating and cooling, hot water, lighting, pool and spa equipment, solar PV and batteries.
By considering NatHERS and Whole of Home requirements together, project teams can better understand compliance pathways, design trade-offs and opportunities to improve energy performance before documentation is finalised.
NatHERS Thermal Rating
Measures the thermal performance of the dwelling and its ability to maintain comfortable indoor temperatures throughout the year.
Whole of Home
Considers the energy use of household systems and appliances, including heating, cooling, hot water, lighting, pool and spa equipment, solar PV and batteries.
Design Optimisation
Helps project teams identify opportunities to improve thermal comfort, energy efficiency and compliance outcomes early in the design process.

Integrated Expertise
NatHERS, BASIX, planning and sustainability expertise delivered through a single consultancy team.
Our NatHERS Process
Our process is designed to help project teams identify thermal performance opportunities early and navigate NatHERS and Whole of Home requirements with confidence.
1. Project Review
We review architectural plans and identify applicable NatHERS, NCC and Whole of Home considerations.
2. Thermal Performance Assessment
We assess thermal performance and identify design factors that may influence rating outcomes.
3. Whole of Home Review
Where applicable, we review household energy assumptions including heating, cooling, hot water, lighting, solar PV and other relevant systems.
4. Certification and Support
We prepare NatHERS documentation and provide practical guidance throughout the approval process.
