Design And Implementation Of Energy Consumption Calculation And Evaluation System During Highway Project Construction

With the rapid development of economy of China,energy is also consuming rapidly.Therefore,a series of laws and regulations on energy-saving and emission reduction have been proposed in China,which explicitly require the energy conservation assessment of major construction projects of fixed assets,including expressway.However,since the energy-saving evaluation of expressway construction projects in China is still in the primary stage,most of previous energy-saving evaluation reports are major in qualitative analysis,and there are few objective and completed energy-saving calculation methods and evaluation system,which make the highway project of energy audit work hard to achieve the objective and accurate.Therefore,it is urgent to study the calculation and evaluation methods of energy consumption in expressway construction projects,and to develop the corresponding software system for energy consumption calculation and evaluation,so as to provide theoretical basis and practical technical method.Based on research of the science and technology project ‘Guangdong Province Expressway Construction Project Energy Conservation Assessment Model,Countermeasure and Local Guidelines' of Department of Transportation of Guangdong Province,calculation model,method and evaluation criteria of energy consumption during expressway construction are discussed in this paper.Quantitative calculation of energy consumption generated by engineering entities is realized by calculating the energy consumption separately while dividing the sub-projects into solid models.System workflow and functional requirements of calculation of energy consumption and energy-saving evaluation for expressway under construction are put forward based on the analysis of the energy consumption data of expressway projects under construction in Guangdong Province.Overall design,functional design and structural design of the system are carried out and system of calculation of energy consumption and energy-saving evaluation for expressway under construction is developed.The result of the application test of the system shows that: the function of calculation and rapid evaluation of the energy consumption in expressway under construction is realized,which could provide effective technical methods for energy consumption and energy-saving evaluation of expressway under construction.
