Matrak vs Cerclos (eTool)
Cerclos (formerly eTool) models whole-of-life impacts. Matrak measures the quantities from the drawings first.
What is Cerclos (eTool)?
Cerclos, formerly eTool, is an Australian-founded life-cycle assessment platform for whole-of-life building impacts to EN 15978. Projects are built from manual entry, templates, or Revit and CSV imports. It includes the NABERS dataset and supports Green Star, IS, LEED and BREEAM reporting.
Where it shines: Whole-of-life LCA to EN 15978, Australian roots and datasets, and reporting for the main rating tools.

The difference that matters
Someone still has to enter or import every quantity. Matrak reads the PDF drawings and produces the bill of quantities with upfront carbon on each line in about 30 minutes, marked up so a sustainability lead can check it, and ready to carry into a full LCA.
A carbon tool is only as good as the quantities fed into it, and producing those quantities is the slow, expensive part: a consultant rebuilding a bill of quantities by hand, often months after the drawings. Matrak's AI measures them straight from the PDF drawings in about 30 minutes, applies supplier EPDs first and NABERS factors where there are none, and shows every quantity marked up on the drawing. Run it again on the next revision and you see the carbon change beside the cost change.
Frequently asked questions
Does Matrak replace an LCA tool?
Not for a whole-of-life LCA or a certified rating. Matrak measures upfront embodied carbon (cradle-to-gate, A1 to A3) for each line of the bill of quantities, from the drawings. Many teams use it to get the quantities and a first carbon number fast, then carry the bill into their LCA tool or a NABERS assessment.
Where do the carbon factors come from?
Your suppliers' Environmental Product Declarations (EPDs) when you attach them. Otherwise the NABERS National material emission factors database (v2026.2), the dataset GBCA's Green Star Buildings requires for its Upfront Carbon credit.
How long does it take?
About 30 minutes for a typical project, from PDF drawings to a bill of quantities with carbon on every line. There's no model to build and no quantities to type in.
Can we export it?
Yes. Excel, CSV and the quote all carry the carbon columns, or push it straight into Matrak.
