On the other hand, the dynamic simulation method has a high accuracy compared to the actual building, but it has a disadvantage that it is difficult to use and the simulation analysis time is long.

The use of simulation technology in building energy performance analysis is essential, and there is a growing demand for a method that can improve user accessibility by utilizing highly accurate dynamic simulation.

EnergyPlus is a program that reconstructs the program's benefits by combining the benefits of BLAST and DOE-2 with the US Department of Energy (DOE) in 1995 as a dynamic energy simulation program. It is used as an authorized program for energy performance prediction at design time. Unlike other dynamic simulation programs, Energy Plus has a feature that input and output files are organized in text format so that other developers can configure input and output files.

According to the present invention, in implementing dynamic simulation based on the energy plus engine, a simulation server connected with BEMS data as a user-oriented simulation tool by improving the present input / output method configured in a text format and an operating system using the same I want to.
