Abstract：As super high-rise buildings proliferate,intelligent emergency lighting systems have become critical for safety assurance.Focusing on their structure,functions,and value,this study employs AHP-based cost-risk assessment together with economic indicators such as NPV and PBP to analyze a representative case.Results show that uncertainties in design and construction,along with key-equipment prices,exert the greatest influence on overall cost and economic viability,whereas intelligent O&M and energy-saving measures can markedly reduce long-term expenses.The findings provide a scientific basis for optimizing system design,guiding investment decisions,and promoting wider adoption.
