The purpose of the paper is to compare energy rating tools for office buildings(ECO2) and commercial program EneryPlus to analyze the characteristics of ECO2. To this end, the energy requirements of two programs in accordance with a variety of input variables(U-value, SHGC, Window to Wall Ratio, Ventilation Rate, Internal Heat Gain) were compared. As a result of analysis, ECO2 and E+ showed the difference of result, an average of 13.0%, and this was considered attributable to the difference between meteorological data and analysis algorithm(quasi-stationary vs dynamic). In addition, ECO2 was insensitive to U-value of window and ventilation rate. Thus, it is needed to validate ECO2 through additional simulations and experiments relating to the U-value and ventilation rate in the future. |
