Fenestration Fundamentals Review

Use this page to test your understanding before applying the course concepts in the calculator or on a live project.

Scenario Assessment

A project has mixed window types, uncertain supplier values and glazing on several orientations. Explain how you would group, calculate and document the check.

Write your answer in your own notes, then compare it to the course lessons, reference points and worked examples.

Review Questions

1. How would you apply "Scope and Key Terms" on a real project?

By the end of this lesson you should be able to decide what must be included in a fenestration check and what information you need before calculating.

2. How would you apply "Orientation and Solar Groups" on a real project?

By the end of this lesson you should be able to group each elevation before applying SHGC checks.

3. How would you apply "Glazing Percentage" on a real project?

By the end of this lesson you should be able to calculate the percentage that drives the applicable performance limits.

4. How would you apply "U-Value and SHGC Weighting" on a real project?

By the end of this lesson you should be able to calculate weighted U-value and SHGC values for a storey or orientation group.

5. How would you apply "Shading and Roof Lights" on a real project?

By the end of this lesson you should be able to identify when shading can be counted and when roof-light rules apply.

6. How would you apply "Worked Compliance Workflow" on a real project?

By the end of this lesson you should be able to run a clean first-pass fenestration assessment and know what to adjust when it fails.

7. What should you do when a project input is uncertain or unsupported?

Flag the missing evidence, use a conservative assumption where appropriate, and avoid claiming compliance until the information is confirmed.

8. What should every final compliance note make clear?

It should show what was checked, which evidence supports the inputs, what assumptions were made, and which SANS 10400-XA reference points apply.
