Abstract

Hainan lies in a tropical maritime monsoon climate characterized by high temperature and humidity, intense solar radiation, frequent typhoons and rainstorms, and severe salt-spray corrosion, which poses great challenges to the construction and quality control of star-rated green buildings. Based on these climatic features, this paper analyzes the challenges in climatic environment, green technology adaptation, construction organization, and quality control, and establishes a “six-in-one” key construction technology system covering wind resistance, corrosion protection, heat insulation, damp proofing, energy efficiency, and ecological performance. The system includes typhoon-resistant foundations and main structures, wind-resistant envelope installation, salt-spray corrosion protection, dry-hung exterior insulation with ventilated cavities, integrated photovoltaic-waterproofing-insulation roofs, energy-efficient windows and shading, moisture-proof and ventilation control, renewable energy utilization, rainwater reuse, and prefabricated green construction. A whole-process quality management system featuring “preventive control beforehand, strict control during construction, and verifying control afterwards” is also developed for design, construction, acceptance, and operation-maintenance stages, supported by BIM, intelligent site monitoring, and digital quality records. A two-star green office building in Haikou shows that the system can reduce summer indoor temperature by 3–5°C and air-conditioning energy consumption by more than 40%, achieve salt-spray resistance of over 5,000 hours, and maintain envelope integrity under typhoons. This study provides a replicable “Hainan solution” for green buildings in tropical and coastal regions.
