| Energy is the foundation and impetus of economic development.As the economy in Shanghai develops rapidly,the imbalance between supply and demand of energy becomes a bottleneck which restricts the development of its economy.Shanghai has a large number of buildings,and the energy consumption in this area occupies a big part in energy consumption over the society.Compared with other areas,the construction industry has higher energy-saving potential and its costs are lower as well.The efficiency of energy conservation will directly influence the emission reduction goal set by Shanghai municipal government that by 2020,the total energy consumption should be controlled under 0.125 billion ton of coal.On the point of full life-cycle,this thesis aims to analyze the elements which influence the Shanghai's construction energy-consumption and find out the key factors,which helps the government understand the reality of energy-consumption in construction industry and put forward targeted solutions on policy.Based on the research experience and theories on energy-consumption of construction field both abroad and at home,this thesis firstly conduct a statistic analysis on full life-cycle of Shanghai's construction,which works out the energy-consumption in producing of construction materials;running of present buildings;and constructing,maintaining,and dismantling newly-built buildings to get the full life-cycle energy-consumption from 2000 to 2014 in Shanghai and analyze its variation trend.Secondly,in terms of theories related to the STIRPAT model and based on the analysis on elements of energy-consumption of Shanghai's construction of full life-cycle,this thesis selects urbanization rate,average living space per person,household consumption level,value added in tertiary industry,production value in construction industry,value added in manufacture,and per unit of total output value;and match the model by using ridge estimate method so as to find out the key factors that influence the construction energy-consumption of full life-cycle.Thirdly,based on different variation trend of these elements,I set two scenarios-smooth development and rapid economic development,and predict the demand of Shanghai's construction energy-consumption in the future under such two scenarios,conduct a comparative analysis on them.Lastly,according to the results of the above three parts,I put forward targeted energy-saving methods towards Shanghai 's building energy-consumption of full life-cycle.The conclusions of this paper are as follows:firstly,the construction field has become the biggest part in Shanghai's energy-consumption,the proportion of construction energy-consumption of full life-cycle in Shanghai's total energy-consumption is increasing year after year,the proportion of energy-consumption of construction material production in construction energy-consumption of full life-cycle is nearly the same as the proportion of the running of present buildings does;secondly,the output of construction industry has the biggest positive influence on the building energy-consumption of foll life-cycle,the influence of urbanization,household consumption and the tertiary industry is nearly the same,and the inhibiting of value added in manufacture on the building energy-consumption of full life-cycle surpasses the energy-consumption of total output per district;thirdly,Shanghai's construction energy-consumption of full life-cycle is sensitive to the changes of average living space per person and urbanization rate;Fourthly,the present energy-saving technology and policy cannot ensure the reach of Shanghai's goal of 2020,and it's important to work harder in building energy conservation field,build ecological city,improve the energy-saving efficiency,and enhance the development of service industry related to building energy efficiency. |
