Building thermal environment regulation and control integrates dynamic insulation materials (e.g., phase change materials, aerogels), intelligent ventilation systems (IoT-based sensor networks with machine learning optimization), renewable energy coupling technologies (solar-geothermal heat pumps, PV-thermoelectric synergy systems), and envelope optimization (shading, natural ventilation, green roofs) to achieve precise control of indoor temperature, humidity, air quality, and thermal comfort. It aims to reduce energy consumption, suppress pollutants and mold growth, and promote healthy building practices alongside life-cycle low-carbon management. This field focuses on balancing human-centric needs (thermal comfort and health) with energy-environmental sustainability, spanning from individual buildings to urban-scale thermal environment optimization
