Research on Synergistic Optimization Paths for Green Renovation of Existing Public Buildings in the Context of Carbon Peaking and Carbon Neutrality

Abstract

In recent years, with the rapid development of China's social economy and the growing awareness of environmental protection among the general public, the problems of excessive resource consumption and environmental pressure caused by traditional construction methods have become increasingly prominent, which have emerged as a key bottleneck restricting the high-quality development of the construction industry. Currently, China has a large stock of existing buildings; among them, existing public buildings serve as typical energy-intensive building stock, and relevant statistics indicate that the energy consumption during their operational phase accounts for more than 40% of the total building energy consumption. Moreover, most existing public buildings were constructed with relatively backward construction technologies at that time, resulting in high energy consumption and poor energy efficiency performance, and such drawbacks are significantly incompatible with the core requirements of China's current sustainable development strategy. In this context, green building technology, characterized by its energy-saving, environmental-friendly and high-efficiency features, has gradually become a new development trend in the construction industry, as this technology not only significantly improves the comfort level of buildings, but also effectively reduces environmental pollution during the construction process and cuts down energy consumption in the operational phase of buildings. Against such a backdrop, further advancing the green energy-saving retrofitting of existing public buildings has become an inevitable choice to improve building operational energy efficiency, promote the low-carbon transformation of the construction industry, and facilitate the achievement of dual-carbon goals, and this paper focuses on analyzing the synergistic optimization paths for the green retrofitting of existing public buildings, puts forward targeted design strategies for green retrofitting projects, and explores innovative approaches to the green retrofitting of existing buildings.
