# Hygrothermal Specification & Modelling: On-demand Training
One of our most accessed on-demand courses is [Moisture](/support-and-training/on-demand-courses/moisture.md), a 54-minute course that provides a comprehensive understanding of advanced moisture assessments. Available on most plans, it's been a great detailed introduction to the topic.
But we've heard your feedback! By popular request, we're developing an advanced version of this course for users particularly interested in the challenges of hygrothermal simulation for wall and roof systems.
Launching **November 12th**, this advanced course will cover challenges across both typical and advanced construction, from precast panel systems all the way through to straw bale and rammed earth construction.
We'll be using multiple software options, including **Better Building, WUFI, and Delphin**, to explain how best to approach these systems and fully comprehend hygrothermal modelling outputs.
The course will also provide a strong focus on the fundamentals: the mathematical background behind hygrothermal modelling, plus a detailed appraisal of the inputs that go into the process. Our goal is to deliver a complete, third-party explanation without influence from suppliers or other biased opinions.
Interested in early access? We'd love to hear from you! Simply click the link below, and we'll add you to our list and drop you a line before launch.

## 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/hygrothermal-specification-and-modelling-on-demand-training.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.
