Energy, daylight, moisture and carbon.

Design better buildings.

The cost-effective, sustainable design platform that empowers engineers and architects to effortlessly achieve building compliance and beyond.

Removing the 'busy work' of compliance .

Start with a building code.

AU / NZ building code compliance is mandatory, setting minimum performance outcomes for your projects. But let's face it, rules can be a little boring!

H1 Acceptable Solution AS1/2
H1 Verification Method VM1
NCC J1.5/J4D6 Walls and glazing
NCC 2019 - V2.6.2.2 Verification using a reference building
JV3 /J1V3 Verification using a reference building
G7 Natural Light Verification Method VM1
Total R-value (AS/NZ 4859.2/ NZ 421/ISO 6946)
Moisture (ASHRAE 160/ DA07)

Through an in-depth understanding of AU / NZ building code requirements, with EnergyPlus™ and Radiance under the hood, our modelling workflows remove the 'busy work' of compliance, providing dedicated solutions and automated reporting!

Green Star, BESS, Home Star, NABERS and more.

Better buildings go beyond the building code.
