Abstract:With the increasing emphasis on environmental protection and sustainable development in society, the application of low-carbon concepts in the field of architecture has become increasingly crucial. In order to achieve the low-carbon goal of large public buildings, this article will start with an overview of low-carbon concepts, elaborate on the design principles of spatial layout of large public buildings under low-carbon concepts, and deeply analyze the design points such as building orientation, functional zoning, and traffic flow integration in large public buildings, in order to effectively reduce the carbon emissions of large public buildings and provide useful references for the sustainable development of the construction industry.
