With the concept of integrating design into nature, the giant panda national park built by CSCEC highlights the integration and openness with the surrounding environment, and collects and filters the rainwater by means of invisible eaves gutters in light of the rainy weather in Ya'an, so that the utilization rate of non-traditional water sources reaches 30.5%, which is more than twice that of normal projects. Integrating green construction into architectural design, the passive measures such as covering the roof with soil, ventilating naturally and storing heat through thick walls enhance its value for ecological demonstration and form an interactive high-performance green building.
