Which region includes the southeastern parts of the United States and experiences hot and humid conditions?

The Hot-Humid Region encompasses the southeastern parts of the United States, characterized by its warm temperatures and high humidity levels, particularly during the summer months. This region is influenced by warm ocean currents and receives significant rainfall throughout the year, contributing to its humid subtropical climate.

In architecture and design, understanding this climate is essential for making informed decisions about building materials, HVAC systems, and the overall design to ensure comfort and energy efficiency. The hot and humid conditions require considerations such as ventilation, shade, and moisture control to enhance occupant comfort while minimizing energy consumption.

The other regions mentioned, including the Cool Region, Hot-Arid Region, and Temperate Region, do not accurately describe the climatic conditions of the southeastern United States. Each of these regions has distinct characteristics that are not representative of the humidity and heat typical of the area described in the question.
