Enter your construction R-values and thermal envelope areas. Get an instant pass/fail against the H1/AS1 6th Edition reference building — the same verdict engine as the paid ConsentIQ H1 tool. Runs entirely in your browser; nothing is uploaded.
Opaque doors are assessed at the H1/AS1 default R0.18 (para 2.1.2.13).
Tick only if the design has integral heating in that element (e.g. in-slab underfloor heating). Heated elements carry higher minimum R-values under Table 2.1.2.12.
ConsentIQ H1 reads these R-values straight off your PDF drawing set — sections, specs, window schedule — then produces the lodge-ready H1/AS1 6th Edition schedule: NZS 4214 parallel-path derivation, source evidence for every value, minimum-R checks and a designer declaration. Same engine, less typing. $14.50 per schedule during Early Access.
Yes — free, no sign-up, and it runs entirely in your browser, so nothing you enter is uploaded. It uses the same verdict engine as the paid ConsentIQ H1 tool. The paid tool adds the AI drawing parse and the lodge-ready schedule.
The Calculation Method compares your proposed building heat loss against a reference building of the same dimensions built to the H1/AS1 6th Edition reference R-values (Table 2.1.2.7). You comply if proposed heat loss is at or below the reference, every construction meets its minimum R-value (Table 2.1.2.12), and the wall glazing ratio is 40% or less.
If a required input is missing — a zone, an area, or an R-value that would otherwise be silently treated as zero heat loss — the tool abstains instead of guessing. A missing R-value counted as zero would understate heat loss and produce a false pass, so the engine refuses. Fill the flagged fields and re-check.
It means the numbers you entered pass the H1 Calculation Method. It does not check that those R-values match your drawings, nor the rest of your consent. Treat it as a fast pre-lodgement sanity check, not a producer statement.
