Thermal Performance Report
Detailed thermal comfort assessment and verification to demonstrate compliance and guide a more comfortable, efficient home.
A thermal performance report goes beyond a single star figure to explain how your building fabric manages heat across the year. It is used to verify compliance, compare design options, and support DA or certification where a deeper justification of thermal comfort is required.
What’s included
We model heating and cooling loads, identify weak points such as unshaded west-facing glass or under-insulated roofs, and quantify the improvement from each proposed change so you can make informed decisions.
What’s included
- Annual heating & cooling load analysis
- Zone-by-zone thermal comfort breakdown
- Design improvement options with quantified impact
- Verification suitable for compliance or council
- Plain-English summary for non-technical clients
Modelled using accredited NatHERS software in line with NCC 2022 thermal comfort provisions.

FAQ
Thermal Performance Report - your questions answered
A NatHERS Certificate provides the compliance star rating; a thermal performance report adds detailed analysis and design guidance, which is useful for optimisation or where a deeper justification is needed.
Yes - by identifying the fabric improvements (glazing, insulation, shading, sealing) that cut heating and cooling demand, the report targets the changes with the biggest payback.
