Abstract：The proposal of China's"dual carbon"goals has determined the sustainable development direction of China's construction and building use.As an important component of total building energy consumption,lighting energy consumption directly affects the progress of achieving the"dual carbon"goals.Based on practical engineering experience and combining computer technology with intelligent control methods,this paper conducts multiple sets of lighting energy-saving retrofitting practice verification by investigating the current status of lighting energy consumption and energy-saving needs in typical scenarios such as commercial buildings and public buildings.Three typical scenarios were selected for retrofitting:a 150000 m2 large commercial complex,a 92000 m2 office building,and an urban underground parking lot.The results show that the comprehensive application of LED high-efficiency lighting and intelligent control system energy-saving technologies can reduce building lighting energy consumption by 35%to 60%,corresponding to a 28%to 45%reduction in carbon emissions.The research findings provide actionable practical paths and data support for the construction industry to achieve the"dual carbon"goals through lighting energy-saving technologies.
