    Purpose: The government is implementing various policies and systems to reduce energy consumption in buildings, including the certification of building energy efficiency ratings and the strengthening of energy-saving design standards for buildings. The purpose of this study is to analyze cooling and heating energy demand by combining factors such as total floor area, number of floors, window-to-wall ratio, and lateral-to-longitudinal ratio, rather than focusing solely on the performance of the building envelope. This study aims to identify the optimal combination of factors that contribute to minimizing energy demand. It proposes a building form that can be predicted based on the scale of office buildings during the architectural planning and design stages, with the intention of using it as a reference. Method: The methodology of this study involved creating various office building models by combining different total floor areas, numbers of floors, window-to-wall ratios, and lateral-to-longitudinal length ratios, and then conducting simulations using the ECO2 program. Result: The analysis showed that the total energy demand was lowest for a 5-floor building with a window-to-wall ratio of 30%, and highest for a 20-floor building with a window-to-wall ratio of 60%. Additionally, for all total floor areas, the energy demand was lowest at a lateral-to-longitudinal length ratio of 1:1.5, while the highest total energy demand was recorded at 2.5:1.
