Course Outcomes

  • Identify acceptable shading strategies.
  • Measure projection and height relationships.
  • Avoid counting shading that is not reliable or documented.

Lesson Summaries

Lesson 1 / 15 min

Purpose of Shading

Understand when shading contributes to compliance.

Objective: Know why external shading affects solar heat gain.

Lesson 2 / 25 min

Projection Method

Measure overhang projection and height relationship.

Objective: Decide whether an overhang should be treated as compliant shading.

Lesson 3 / 20 min

Shading Evidence

Prepare documentation for shading assumptions.

Objective: Create shading notes that can support the compliance result.

Common Mistakes To Avoid

  • Claiming shading that is not external, permanent or measurable.
  • Measuring projection and height from inconsistent points on the opening.
  • Counting uncertain future screens or occupant-controlled items as compliant shading.
