The Cost Evaluation Research On The Transformation Of Existing Large Public Building-Energy Saving

In the past the "Eleventh Five-Year" period, the energy shortage problem beganby humans pay attention to it. All countries to take effective measures to protect thecountry’s energy loss and energy compete and even lead to war. So, how efficient useof energy become another problem that humans compete for energy should beseriously studied. In China, only the buildings energy consumption already accountsfor more than30%of the total energy consumption of the national economy, andtheannual rate of nearly1%increments, this one is fierce speed the growth ofdeveloping countries is a very scary problem. energy growth will stop. Therefore, thebuilding energy consumption is a problem at this stage to focus on research. At present,the majority of our existing buildings of less than the standard requirements of energyconservation, especially the largest share of total construction area of the minimumenergy consumption for large public buildings. Large public buildings, energy saving isthe urgent implementation of a project, but this project in volves several main sectors,technology, funding, policies and regulations, so in the "Eleventh Five-Year" period,Xi’an, energy-saving work carried out only the transformation of300,000squaremeters, then how in the "12th five-Year" period a wider range of energy saving, thelevel of judgment of the cost of renovation objective assessment of research.The main contents of this article are as follows:Firstly, the research object positioning and its characteristics range and pointedout that both large-scale public building energy saving energy savings are significantand of great significance. Cost theory, and then to the full life cycle engineering and construction project life cycle theory and engineering construction projects and thephasing of the full life cycle of both large-scale public building energy-saving modelconstructed on this basis, the establishment of full life-cycle cost model, carried out adetailed life cycle cost for both large public buildings energy-saving divided, andfinally the use of fuzzy Evaluation for cost evaluation of the model, obtained both largepublic buildings energy-saving lower-cost energy efficiency significantly conclusion,this energy-saving renovation project is suitable for large-scale promotion in the wholesociety.
