For optimal solar access, a single-family subdivision should be aligned how?

For optimal solar access in a single-family subdivision, alignment should ideally be oriented from east to west. This configuration allows for maximized sunlight exposure throughout the day, especially in the mornings and afternoons. Homes positioned in this manner can benefit from sunlight as the sun rises in the east and sets in the west, creating opportunities for natural heating and lighting.

When designing subdivisions, consideration of solar access is crucial for energy efficiency, which affects both individual homeowners and overall community sustainability. East-west alignment supports passive solar design principles, which can reduce reliance on artificial heating and cooling systems, leading to lower energy costs and increased comfort for residents.

Moreover, while a north-south alignment (the other option) might also allow for some level of solar access, it typically does not provide the same extent of exposure throughout the day as the east-west alignment does. Thus, the east-west orientation stands out as the best choice for achieving optimal solar access in residential development.
