Prove that smarter logistics and faster, cleaner sites beat the industry baseline — not by hiding the materials, but by wasting nothing in transit or execution.
Material-driven. Punch in a quantity, the tool slaps on a generic transport distance and a fat 5–10% waste penalty. Efficient builders get the same score as sloppy ones.
Logistics-driven. Mass sets the floor, but your real distances, full trucks, tiny waste factor and shorter programme are the levers — and every saving is shown against the baseline.
No logins yet — just pick a project, or start a new one. Everything you change saves automatically.
Add the major materials and where they come from. We convert volumes to mass, run the industry baseline (BRANZ default distances, 10% waste, part-full trucks) against Simplicity's optimised logistics (2% waste, full trucks), and show the carbon you save.
| Material | Quantity | Supply origin | Mass |
|---|
Sea distances use container-freight factors; the local road leg is where Simplicity's full trucks and low waste cut the most carbon. Distances come from the BRANZ Transport Scenarios database; factors from MfE 2023 (ME1781).
A5 is the physical act of building — the pour, crane, plant and site energy for each element. Rather than one generic estimate, each construction element has its own activity calculator. Open one below as a blank shell, enter your own quantities and logistics, and see the baseline-vs-optimised saving. (On the Simplicity site these same tools substantiate real projects, prefilled with their data.)
A5 today is mostly guesswork from floor area. To prove real efficiency we capture verifiable primary data on site — these are the tools that will feed the activity calculators:
