Building Structure

Under the background of “ Double-carbon” target strategy, it is the trend to promote the green development of building industry, ventilation and air-conditioning system is a large user of building energy, it is an important issue for how to save energy, low-carbon operation. This article takes an industrial park project in Zhuhai as an example, this paper discusses the design scheme of air conditioning cold source for direct-drive photovoltaic air-conditioning system combined with ice storage, as well as the air conditioning load distribution and electricity price policy of the project, the recommended operation strategy of air-conditioning cold source system can realize low-carbon operation of air conditioning system, relieve peak power load in summer, and reduce the emission of carbon dioxide, sulfur dioxide and other pollutants.

This paper discusses the integrated application of renewable energy in building projects and its management optimization strategies. The article introduces the application of various renewable energy technologies in building projects, including solar photovoltaic and solar thermal systems, geothermal energy, air-source heat pumps, and biomass energy. It also proposes management optimization strategies such as formulating scientific and reasonable energy plans, strengthening technology research and innovation, improving market mechanisms and policy support, enhancing energy reserve and supply security, and promoting intelligent and informatization construction. Additionally, the article points out the challenges faced in the application of renewable energy in building projects and corresponding countermeasures.

This study focuses on the application of modified asphalt in highway construction and the improvement of pavement durability. Analyzing its material properties, construction techniques, and actual effects, it is shown that modified asphalt can significantly enhance the fatigue resistance, rutting resistance, and crack resistance of road surfaces, and perform well in complex climates and heavy traffic. Practical cases demonstrate its successful application in different road sections, providing technical support and practical basis for highway construction. Finally, looking forward to the development trend of highway pavement material technology, the prospects of intelligent materials and environmental protection technology are mentioned.
