Research on Low-carbon Technology Integration Design and Carbon Reduction Potential Analysis of the Tower Crown of Super High-rise Buildings
The tower crown of super high-rise buildings features great influence,high building cooling load intensity,strong chimney effect,compact functional space,and limited transportation size of mechanical and electrical equipment.It is technically difficulty to carry out the energy-conservation and carbon-reduction work,but with remarkable demonstration significance.Based on the local climate,building characteristics and energy consumption characteristics,the R&D,practice and integration of low-carbon technologies were explored in the tower crown of China Overseas Chengdu Super Tower Project for the first time.The crown adopts performance-based design methods and economic analysis,study were made on low-carbon and energy-saving technologies such as high-performance enclosure structure,high-efficiency electromechanical system,and renewable energy utilization,and the integrated application of a variety of low-carbon technologies in the crown part of the tower was creatively realized based on crown architecture and local climate.By establishing an analysis model of building energy consumption and carbon emissions,this paper optimized and quantitatively analyzed the energy saving and carbon reduction potential of various integrated technical measures to identify the premium technical solution.The building energy saving rate and carbon dioxide reducing ratio of the project are 50％higher than that of the benchmark building.Through research and analysis,this paper realized the integrated design and application of low-carbon technologies in the project of tower crown of super high-rise buildings,offering technical reference for other similar projects in China.
