How does a home's orientation affect passive solar heating?

A home's orientation plays a crucial role in maximizing sun exposure during the winter while minimizing it in the summer. This strategic positioning allows for passive solar heating, which utilizes natural sunlight to warm the home without relying heavily on mechanical heating systems. In winter, when the sun is lower in the sky, a well-oriented home can capture more sunlight through its south-facing windows, heating the interior spaces effectively. Conversely, during the hotter summer months, the same orientation helps minimize direct sunlight entering the home, keeping it cooler and reducing the need for air conditioning.

This approach enhances energy efficiency by leveraging the natural energy from the sun to maintain comfortable indoor temperatures throughout the year, thereby reducing energy costs and reliance on fossil fuels. Utilizing passive solar heating effectively contributes to a home's overall sustainability and comfort.
