A true early-stage embodied carbon calculator.

Generate quick, accurate, and interpretable estimates - early on, when you need it the most.

Instant estimates

Generate carbon estimates instantly based on existing building archetypes.


Apply project specs with several clicks, no matter how much detail you have.

Accurate results

Tuuli uses verified EPDs to generate estimates, not wild industry averages.

So simple - yet so powerful.

Use Tuuli to generate embodied carbon estimates at the very start, so you have time to make impactful design choices.

No design? No problem

Tuuli produces estimates even when you don't have all the information.

Just specifying details like GFA, structure type, and location can produce a baseline embodied carbon target that your team can easily reference.

Intuitive customisation

Pick material combinations on our customisation canvas, just like making a flowchart.

See how your decisions affect the embodied carbon of your design, in real time.

Get specific - and accurate

Tuuli uses verified EPDs, so embodied carbon estimates are based on real materials - not misleading industry averages.

Get the carbon conversation started early.

We get it - handling embodied carbon is difficult. Few teams truly understand how it affects building design, let alone how it fits into real-life workflows.

We want to change that, and that's why we're building Tuuli.
