What is the warmest part of the building in winter?

1. North

2. East

3. South

4. West

The correct answer is: South

The warmest part of a building in winter is typically the southern exposure. This is due to the path of the sun across the sky in the northern hemisphere. During winter months, the sun is lower in the sky and travels across the southern part of the horizon. As a result, southern-facing walls and windows receive more direct sunlight throughout the day, capturing heat and warming up those areas of the building. In contrast, north-facing areas receive significantly less sunlight in winter, leading to cooler temperatures. East-facing areas benefit from morning sunlight, which can provide warmth but not as much as the south during the shorter winter days. West-facing areas receive afternoon sunlight, which offers some warmth but tends to cool down quickly as the sun sets. This understanding of solar orientation is crucial for effective building design and landscaping, which aim to maximize energy efficiency and comfort within a structure.
