With the accelerating global urbanization and the deepening "dual carbon" goals, the building sector urgently requires systematic solutions that balance safety, energy efficiency, and environmental friendliness. Our team focuses on resource optimization across the entire lifecycle of buildings, with a core emphasis on passive energy systems and intelligent control technologies. We address the challenge of integrating building safety with energy efficiency through passive systems and climate-adaptive design, developing precise energy consumption models. We have created an integrated technology system for "daily energy conservation and emergency safety" collaboration. Our innovations have led to breakthroughs, such as a 30% reduction in energy consumption for multi-story buildings and smoke exhaust efficiency exceeding national standards by 1.6 times, significantly reducing the environmental impact across the entire industry chain. This supports high-density urban renewal and the achievement of the dual carbon goals, advancing sustainable development and a dynamic balance between people, buildings, and nature.
