# 3D Geometry in SketchUp

<figure><img src="/files/NlgyBf4WyAO299aMNJxv" alt=""><figcaption></figcaption></figure>

This 33-minute course is part of a specialised series designed to help professionals navigate the complexities of building fabric compliance using SketchUp and Speckle. Focusing on the Part J4 provisions of the National Construction Code (NCC) 2022, the course provides detailed instruction on setting up, modeling, and analyzing results to ensure thermal performance and energy efficiency in commercial buildings.

**Course Structure:**

The course begins by introducing Part J4 and its role in determining building fabric performance under the NCC. Participants will learn how to set up a basic 3D model in SketchUp, configure building parameters such as space types, climate zones, and surface matching tools, and export models to Speckle for analysis and simulation.

The second segment focuses on simulations for different building classes, such as Class 5 and Class 9B spaces. Participants will explore how to input details for walls, roofs, floors, and glazing systems, verify the accuracy of inputs using tagging and defaults, and make adjustments to meet compliance standards. This section emphasizes the importance of interpreting thermal performance metrics like U-values and solar heat gain coefficients.

In the final section, participants will engage in advanced analysis and reporting. This module covers generating detailed compliance reports focusing on thermal envelopes, shading systems, and HVAC performance. Participants will learn to customize these reports for submission to regulatory bodies and explore daylight factor assessments to enhance energy efficiency.

**Key Learning Outcomes:**

* Understand and apply the Part J4 building fabric provisions for NCC compliance.
* Gain proficiency in setting up 3D building models and inputting essential parameters in SketchUp and Speckle.
* Develop skills in running simulations and interpreting results for wall, roof, and glazing systems.
* Learn advanced techniques such as thermal envelope evaluation and shading multiplier simulations.
* Produce comprehensive compliance reports tailored to project-specific requirements.

**Course Completion:**

By the end of this course, participants will have a strong understanding of how to ensure building fabric compliance under Part J4. They will be able to confidently model, simulate, and report on the thermal performance of their projects. A Certificate of Completion will be awarded to participants who pass the final assessment with a score of 80% or higher.

## 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/support-and-training/on-demand-courses/3d-geometry-in-sketchup.md?ask=<question>&goal=<endgoal>
```

`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.
