Implementation path and case study of zero-carbon operation of a super high-rise building in hot summer and warm winter zone

The realization of energy-saving and low-carbon development of super high-rise buildings has outstanding demonstration significance for high-quality development and “dual carbon” goals in the building field.Taking a super high-rise building in hot summer and warm winter zone of China as an example,this paper conducts detailed energy consumption analysis and energy system performance diagnosis.The research shows that the form of the air conditioning system in super high-rise buildings is complex,which is the key to energy conservation and carbon reduction.Combining technologies such as temperature and humidity independent control,large temperature difference chilled water system,multi-stage series chillers,and free cooling with outdoor air in the transitional season,the energy consumption of the air conditioning system is effectively reduced,but there is still space for energy conservation and carbon reduction.Subsequently,combined with simulation,the implementation effects of different energy conservation and carbon reduction technologies are explored,and then a zero-carbon operation implementation path is constructed around reducing cooling demand,improving energy efficiency,and increasing the utilization rate of renewable energy,providing reference cases and technical support for similar projects.
