The edge of the eave should be located at the point of intersection of which two angles?

The edge of the eave is an important aspect of architectural design, particularly in relation to how sunlight and weather affect a building throughout different seasons. The correct choice highlights the interaction between solar angles, specifically the winter angle and the summer angle, which are crucial for ensuring proper shading and natural light control.

The winter angle refers to the angle at which sunlight enters a building during the winter months when the sun is lower in the sky. Conversely, the summer angle represents how sunlight enters in the summer when the sun is higher. By positioning the eave at the intersection of these two angles, architects can achieve effective shading that blocks the harsher summer sun while allowing the milder winter sun to warm the building. This design approach not only enhances energy efficiency but also contributes to the overall comfort of the indoor environment.

Choosing the eave location based on these solar angles helps optimize natural light and heating, which can lead to significant energy savings and an improved quality of life for the occupants.
