Dynamic Simulation Study Of Resident Building Energy And The Development Of Energy Simulation Software

ABSTRACT With the development of world building energy saving, theappropriate selection of building material & the optimization control ofHVAC system requires accurate dynamic energy consumption calculating.To meet the need, the computer simulation is absolutely necessarily.However many softwares existing now cannot be applied into engineerpractice due to some problems, e.g. operation inconvenience of userinterface. Thus, we proposed here a new energy simulation softwaresdevelopment idea (more detail for the text). EnergyPlus is a new building energy simulation program supported byU.S. government. Based on the most popular features and capabilities ofBLAST and DOE-2, it is primarily a simulation engine without interface. In North China, the residential building energy consumptioncommonly comes from heating load, however, traditional calculatingmethod often just takes account of the worst fact, which resulting inillogically equipment selection and non-scientific system operation. Inthis dissertation, with the simulation program-EnergPlus, the study hasfinished: 1 On a basis of understanding the introduce of the organization andcapabilities of this software, modeling a resident house dynamic heatingload performance during a given period in an energy conservation uptownof TianJin, compared the calculation results with measured data,suggesting reliability of the results. 2 With the hourly weather data of typical meteorological year, usingthe same model, the house dynamic energy performance was simulated inthe heating period. Analyzed the distinctions between EnergyPlus and theEffective heat transfer coefficient method. 3 The influence of house thermal mass, thermostat, infiltration onbuilding energy was studied. 4 With the advantages of the structure and object-orientation of VisualBasic 6.0, a friendly user interface for EnergyPlus was developed. Though above researches, we demonstrate the feasibility of dynamicsimulation method (EnergyPlus Software) for building energy-saving inABSTRACTChina, point out reasonable index for building energy saving in NorthChina. Also, the developed user interface is convenient for futureapplication.
