Practical Exploration of Net-Zero Building Technology in Hot Summer and Cold Winter Regions—Qingdao Sino-German Eco-Park Longfor Guangnian Project as an Example

Abstract

Energy saving and carbon reduction in the building sector is crucial to the realization of China’s “double-carbon” goal, and the development of passive house/net-zero buildings is an important initiative to achieve this goal. This paper takes Longfor Guangnian, a passive house project in Qingdao, as a case study, summarizes the technical practice of net-zero buildings in coastal areas with hot summers and cold winters, and gives an optimization plan in combination with the existing problems of the case. The final result is to improve the building energy efficiency and optimize the building energy structure. It accumulates experience and provides reference for the promotion of net-zero buildings in cold areas, and provides support for green and low-carbon development in the field of housing and urban-rural construction.
