Application research on energy consumption analysis in electrical energy-saving design of building engineering
CHEN Jun
Abstract：Taking a civil high-rise building in Nanjing,Jiangsu Province as the research object,the IIT intelligent analysis method is used to study the monthly distribution of building energy consumption.The results show that the actual electricity consumption of the building and the calculated electricity consumption by the IIT method exhibit a significant multi-peak feature,with electricity consumption peaks occurring from June to September and from December to the following February.The average error coefficient and root mean square error coefficient between the actual electricity consumption and the calculated electricity consumption by the IIT method are both within the precision range,indicating that the calculation results of the IIT method have sufficient precision and can reflect the actual situation well.In view of the energy consumption analysis results,combined with the time when the peak energy consumption months appear and the electricity and gas sub-items with the largest energy consumption,the following design methods are proposed in the electrical design:using high-efficiency energy-saving electrical appliances and lighting systems,intelligent power management systems,renewable energy utilization,high-efficiency gas equipment,and intelligent control systems.
