Abstract:

Climate change and its wide-ranging influence are driving countries worldwide to implement carbon neutrality strategies.Starting from the building theoretical system of carbon neutrality, this paper proposed the basic principles of carbon neutrality and climate adaptive building design and emphasized the dynamic-balance consideration between the energy-saving benefits (operational carbon) and implementation costs (embedded carbon) in the whole life cycle of passive buildings.According to regional climate characteristics and urban morphological features, this paper also focused on the adaptive feedback of passive buildings to the physical environmental characteristics such as wind, heat, and light at the site.Furthermore, this paper identifies the carbon source/sink scenarios of passive buildings in Chongqing from aspects of site and climate, building type, the envelope structure, ventilation, lighting, renewable energy utilization, and other technologies, and discusses the potential of applying passive strategies to reduce carbon emissions from buildings under the climates of "humid and hot, humid and cold, and weak winds" in Chongqing.This will promote the construction of a net-zero carbon city in Chongqing.
