Climate change is a major global issue of general concern to the international community. As a developing country focusing on environmental protection, China has adopted a series of relevant policies and measures to address global warming, namely, achieving carbon peak by 2030 and carbon neutrality by 2060. It can be said that carbon peaking is China's national policy to actively respond to climate change, and is also an independent commitment based on scientific demonstration; Carbon neutrality is an action goal based on China's national conditions and is also a long-term development strategy with a long-term vision. In order to realize the important long-term strategy of “carbon neutrality” at an early date, low-carbon buildings will gradually come into people's lives. This paper first analyzes the crisis and challenges we are facing under the background of the current era, and expounds how to solve the energy crisis. In this paper, we propose that green and low-carbon buildings will make a significant contribution to solving the problem of carbon pollution. Then, we studied the low carbon scheme of science and technology parks in southern cities through literature review, and case study. Next, taking the project of Block H01-01, Unit PDC1-0401, Lingang New Area of Shanghai Free Trade Zone as an example, we 、analyzed the technical characteristics of the project's climate responsive design and the integrated design of renewable energy buildings, and elaborated its project functions. While satisfying people's demands for scientific research and comfortable living, it also responded to the call of the national “double carbon” goal and completed the task of “strengthening building energy conservation and continuously improving building energy efficiency” in the key work of energy conservation, emission reduction and carbon reduction in Shanghai. Finally, it is concluded that green and low-carbon buildings can make outstanding contributions to the realization of “double carbon” goals in the future, and at the same time provide a more powerful guarantee for human living environment and quality of life.
