What Are Shadow Diagrams in Drafting?

Shadow diagrams — also known as solar access diagrams or sun shadow studies — are technical drawings that illustrate how shadows fall from a structure at different times of the day and year. These are typically calculated for key solar events like:

  • Winter Solstice (June 21)
  • Equinoxes (March 21 & September 21)
  • Summer Solstice (December 21)

Standard times include 9 AM, 12 PM, and 3 PM to demonstrate the extent of shading throughout the day.

Why Are Shadow Diagrams Important?

Shadow diagrams serve both practical and regulatory purposes:

✅ Assess Sunlight Access – Make sure your new development doesn’t unreasonably overshadow neighbouring homes or open spaces.

✅ Meet Council Requirements – Most councils require shadow diagrams as part of development applications.

✅ Guide Smart Design – Influence key design decisions like window placement, building orientation, and use of shading features.

✅ Enhance Livability – Help ensure gardens, living areas, and solar panels receive optimal sunlight.
