H1 compliance without the guesswork
The H1 5th and 6th editions lifted thermal requirements across New Zealand's six climate zones. Roof, wall, floor and window R-values now vary by zone, and getting them wrong is an expensive thing to find at inspection.
Toolie derives the H1 climate zone from the job's address and gives you the correct construction R-values for roof, walls, slab and glazing — then carries them into the specification and the priced quote so what you price is what passes.
- H1 6th-edition R-values by climate zone (1–6)
- Climate zone derived automatically from the site address
- Roof, wall, floor and window targets in one place
- Flows into the spec checklist and the priced quote
- Pairs with the Healthy Homes check for rentals
It’s part of the quote, not a separate tool
In Toolie this isn’t a one-off calculator — it feeds the actual priced quote and the build programme. Describe the job or drop in a PDF plan and Toolie runs the take-off, applies NZ site intelligence and prices it off a real NZ pricebook.

Common questions
Is the calculator the H1 6th edition?
Yes — the R-value tool follows the H1/AS1 6th edition and presents targets by the relevant NZ climate zone.
Does Toolie know which climate zone my job is in?
Yes — Toolie derives the H1 climate zone from the job's address along with wind, coastal and seismic exposure.
Does H1 connect to the quote?
Yes — the R-value targets feed the specification and the priced quote, so the insulation and glazing you quote match the compliance requirement.
