Which orientation is ideal for maximizing morning solar gain?

An east-facing orientation is ideal for maximizing morning solar gain because it allows direct sunlight to enter the building during the morning hours when the sun rises in the east. This exposure will help to naturally warm spaces in the early part of the day, making it particularly beneficial in cooler climates where morning warmth is desired.

Buildings with a strong east-facing orientation can take advantage of this sunlight for passive solar heating, which can lead to reduced energy costs and improved comfort in living spaces. Properly designed windows and shading devices can further enhance the effectiveness of this orientation by allowing sunlight in during the morning while preventing excessive heat gain later in the day.

In contrast, other orientations do not provide the same level of morning light exposure. For instance, a south-facing orientation primarily captures sunlight throughout the day but does not specifically cater to morning solar gain. North-facing orientations receive minimal direct sunlight, particularly in northern latitudes, while west-facing orientations capture afternoon sunlight, which is not beneficial for morning heating needs.
