Hot and humid regions

Which factors are important when designing public spaces in hot and humid regions? In this article, Dr Jennie Sjöholm discusses some aspects.

Hot and humid regions are typically located at the equator, and include parts of Southeast Asia, northeast Australia, Micronesia, Africa, and Central and South America. They also include tropical and marine areas, such as parts of southern Africa, South America, southeast China, and southeast US.

These regions are characterised by either being warm all year round, or having hot and humid summers but cool or even cold winters.

In designing urban spaces, it is important to consider the following:

  • The summer climate is often uncomfortable.

  • Some of the hot and humid areas have strong and destructive storms and floods.

  • Climate change and global warming in making many of these regions less habitable in summer.

In designing urban spaces, it is important to consider minimising the impacts of flooding. Rapid disposal of excess rainwater is essential. Rain protection is needed in public spaces, as is protection from sun.
