The article discusses how the design of buildings affects the indoor temperature and comfort during hot summer months. Researchers looked at traditional Chinese houses and modern rural homes to see how their layouts impact cooling. They found that the design of the traditional houses creates a special indoor climate that keeps people comfortable in the heat. This unique indoor climate is called the building microclimate, which is influenced by factors like the layout and materials used in the building. The study shows that the design of modern homes has changed over time, affecting how well they stay cool naturally.
