# MBIE Kicking Schedule Method to the Curb
The rumors were true! MBIE is ditching the stale Schedule Method for H1 insulation by late 2025. Good riddance; it often led to poor design and overheating.\
\
What's left? The Calculation and Modelling methods. These are effective, cheaper, and might save you $15,000 on a new home! Modelling promises better design flexibility, though the Calculation method still carries design risks with no consideration of solar loads. There's also concern that chasing savings might compromise construction quality.\
\
The kicker? Full implementation won't happen until 2027, as the 12-month transition is delayed a year. If it's about savings, why the wait? Let the market choose now!\
\
On a positive note, MBIE's exploring a separate Far North climate zone for insulation, which seems reasonable. Overall, it's about building smarter and more efficiently in NZ!\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.betterbuilding.io/sign-up-and-plans/news-and-updates/2025/mbie-kicking-schedule-method-to-the-curb.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
