Orientation can help explain when a window or patio may receive direct sun, but a compass direction is not a shadow model. Use this field study to record what you actually observe at your home.

HOW TO USE THIS
A direction is a clue. Your observation is evidence.
DOE daylighting guidance explains why orientation, glazing and shading matter. Trees, roof overhangs, neighboring structures, terrain, season and window geometry can all change the actual pattern.
This tool deliberately does not ask for an address, latitude, roof geometry or energy bill. It does not calculate exact solar position, hours of shade, comfort, glare, HVAC load or savings.
ORIENTATION NOTEBOOK
Choose a direction. Then write down what happened.
Pick the face you are studying and one observation period. The conceptual card changes; the conclusion stays yours.
CONCEPTUAL READING
North-facing
Often receives more even daylight and less direct summer sun; local geometry still controls the real condition.
YOUR FIELD NOTE
No conclusion yet.
Choose a direction and record one real observation. This note separates what you observed from what you only suspect.
PRIMARY REFERENCE STARTING POINTS
General daylight guidance. Not a substitute for measured geometry.
