To achieve indoor thermal comfort via natural ventilation, traditional buildings in South China’s Lingnan region have evolved distinct features tailored to the hot and humid climate conditions, involving site planning, function layout, and construction techniques. This study delves into the influences of these features on aspects such as sun-shading, ventilation, and heat insulation. By analyzing over ten Lingnan buildings in both the traditional and modern forms, several representative standardized models have been developed. Through a hybrid approach of combining qualitative and quantitative methodologies, including simulations, quantifications, and comparisons, several passive heat-protection measures commonly employed in Lingnan buildings were examined and evaluated. The effectiveness of shading, ventilation, and heat insulation in both traditional and modern buildings was assessed, resulting in the compilation of design principles for passive heat protection in buildings located in similar climatic zones. Key findings include (1) Shading: traditional methods reduce sunlight by 54.55%, while modern buildings enhance shading by applying new materials; (2) ventilation: traditional design achieves an outdoor wind speed of 1.5 m/s, improving thermal comfort, while modern Lingnan buildings optimize these principles; (3) insulation: traditional techniques maintain indoor temperatures below 26.0 °C, and modern buildings introduce innovation solutions for improved thermal insulation. In summary, traditional Lingnan design effectively addresses the challenges of the hot and humid climate by employing passive strategies for thermal comfort. Modern Lingnan buildings, in turn, preserve these principles while introducing innovative approaches.

The technical standards for the design and construction of emergency medical facilities play an important role in guiding the conversion of Fangcang shelter hospitals and the construction of emergency infectious disease hospitals and temporary facilities for medical quarantine and observation. However, due to the imperfections and superficialness of the current version of the existing technical standards, further improvement and optimization on the maturity and systematism are necessary. This paper presents an in-depth analysis and comparison on the detailed regulations and terms between the existing 11 sets of technical standards issued by the National Health Commission (NHC) and the provincial competent authorities of Hubei, Zhejiang, Jiangsu, Hebei, Shandong and Beijing. The similarities, disparities and deficiencies of these technical standards are summarized. Then, the primary contents, including the site selection and architectural design, heating, ventilation and air conditioning (HVAC), structural design, electricity intelligence, water supply and drainage, operation and maintenance, environmental health and safety, and fire protection, are analyzed in-depth from the view of infectious disease control and health safety. Furthermore, some critical principles related to the detailed terms of the architectural design, HVAC, electricity and water supply are concluded. Finally, some essential suggestions are proposed for the improvement and revision of these technical standards for better applications.
