Wanhua Huayuan Building
Wanhua Huayuan Building is the largest under-construction ultra-low-energy building in Yantai City, with a construction area of nearly 180,000 square meters for the Wanhua Senior Talent Apartment project. As a demonstration project for ultra-low-energy buildings in Yantai City's clean heating urban areas, multiple green construction technologies have been adopted, such as the construction of ground-source heat pumps under the foundation raft board, polyurethane foam insulation for the cavity wall, and photovoltaic power generation, achieving "zero breakthroughs" and constantly innovating and accumulating experience.
