With the impact of global climate change, the energy efficiency issue of buildings in hot-humid regions has become increasingly prominent. As an important means to address this challenge, ultra-low energy buildings need to optimize the thermal design of their envelopes to achieve the dual goals of reducing energy consumption and improving comfort. This paper analyzes the characteristics of hot-humid climates and combines thermal design principles to propose an optimization scheme for the envelopes of ultra-low energy buildings suitable for hot-humid regions. The optimized design considers the thermal performance of external walls, roofs, and windows, striving to ensure indoor environmental comfort while saving energy. Reasonable thermal design of building envelopes can significantly reduce building energy consumption and improve overall building energy efficiency.
