Abstract

In this paper, the domestic building energy simulation software development and promotion of the application of the analysis of the status and trends of foreign energy simulation software and highlight energy simulation software EnergyPlus. EnergyPlus is the U.S. Department of Energy funded the development of a new generation of building energy simulation software, foreign scholars has been widely used for energy simulation study and there are many EnergyPlus for core building energy simulation software development. The domestic around EnergyPlus more and more load and energy simulation application EnergyPlus simulation software, and improvements to the building envelope, and system optimization research experiment platform. Only a few scholars optimization software application interface, improved software to simulate the basis of equations, and software to increase the analog modules in line with China's actual situation. The main work of this paper is based on the EnergyPlus building energy simulation software development and applied research. Fully study the mode of the EnergyPlus software data organization and data structures based on the principle of software engineering, requirements analysis and interface design, to complete the simulation software design based on the energy consumption of the analog core also completed the first version of the development work. Has developed versions of the module, the user interface and program structure is introduced. The key aspects of this research breakthrough based on EnergyPlus building energy simulation software developed, laid the foundation for the subsequent development work. Of building energy simulation software developed by a combination of research model is designed and constructed, in accordance with this model, the follow-up to the software development work will be carried out in cooperation with the software company. Development has entered a substantive stage, and released the first official commercial release in August 2009. Hope that this work will promote energy simulation software more widely used in the engineering design and build communication feedback platform for scientific research and engineering actual. The authors also used the EnergyPlus software peak cooling load of the air conditioning system of the building envelope, the strong solar radiation effect of low air conditioning load reduction measures. Found through simulation studies, the exterior wall heat transfer coefficient, the reduction of the role of the high reflectivity of the exterior paint on the building energy consumption low; using only low-e glass, high solar radiation to reduce the cooling load the effect is not obvious; outside the window shade and glass shade can achieve very good results, and should be widely applied; low peak load reduction measures while improving the building load distribution structure, in favor of the system in the case close to the design condition run, improve energy efficiency to save energy. On the basis of this study, the authors propose the building envelope and HVAC system design approach, building energy simulation software developed on the basis of this study will support efforts for the realization of this design method.
