The Loading Prediction And Modification Analysis Of Energy Efficiency In Buildings

Energy consumption in buildings has taken a great part in all the energyconsumption of human beings. And the energy efficiency in buildings has become agreat problem which attracted attention of world. In China energy efficiency inbuildings is under developed and begins very late, so research on energy efficiencyin buildings in China is a pressed problem. The main contents of this paper are asfollows:Programmed a software which is used in simulating the dynamic energyconsumption of buildings based on transferring function principle in the language ofvisual basic, at the same time compared with the traditional way of calculation ofenergy consumption in buildings to prove the correctitude of the software;Foundviable way of energy efficiency in buildings in the way of analyzing walls, windows,and many other aspect of structure of buildings, and using the software to analyzethe rate of the contribution of thermal quality to the energy consumption of buildings;Analyzed the rate of the contribution of the different weather to the energyconsumption of the existing dwelling in the way of calculating the energyconsumption in the whole year of the existing dwelling in two model cities choosefrom the region of north China and south China. Also is carrying on the contrast andviability assessments on the energy saving of the existing dwelling between northand southern region, getting the viability assessments and the conclusions inparticular data.To renewing the theory and the data reference of the energy efficiency of theexisting dwelling in the whole country, and accelerate the process of research anddevelopment of the energy efficiency in buildings in China. This paper is based onthe conclusions of the searching of the existing dwelling's energy efficiency inchillness region of China, analyzed the viability assessments of the energy efficiencyof the existing dwelling in north China region and southern region, and got thedirected conclusion.
