Building Energy & Performance Intelligence
Meet Energy Requirements.
Without Guesswork.
From plan to performance in seconds. Our proprietary engine runs a full 8,760-hour whole-year thermal simulation of your design — finding the most cost-effective path to 7-Star compliance before you break ground. No more blind material upgrades.
THE THERMWISE DIFFERENCE
Don't Just Rate Your Design. Optimise It.
Performance Intelligence
We believe energy compliance shouldn't be a guessing game or a budget trap. By analysing your design's thermal behaviour early, we help you identify high-impact variables — so you can achieve 7-Star compliance with the most cost-effective construction strategy.
A VALIDATED CALCULATION PLATFORM — NOT A FORM-FILLING TOOL
Most providers sell a pass. We sell the cost-optimised solution.
Thermwise is built on a proprietary building-performance engine — rigorously validated against the global gold standard for energy simulation, so the numbers behind your cost savings stand up to scrutiny.

WHAT WE DO
From Plan to Performance, We've Got You Covered.
Streamlined Data Extraction
Plan-to-Performance Analysis
We extract geometry, orientation, and envelope parameters from your preliminary drawings to build multi-zone predictive thermal models faster — eliminating tedious data entry.

Design Smarter: See What Makes the Difference
Based on our rigorous multi-prototype thermal simulations (such as our J480 D1 sensitivity studies), we help clients identify which design levers actually move the needle — saving thousands in unnecessary construction costs.

Custom Residential
Custom Residential: 7 Stars, Cost-Optimised
A custom home kept its floor-to-ceiling windows and still hit 7 stars — avoiding an $18,000 triple-glazing upgrade.
Volume Builders
Volume Builder: 12-Plan Library Standardised to 7 Stars
A mid-size SA builder's 12 standard plans were batch-upgraded to a reliable 7 stars with one optimisation matrix.
