Abstract
Purpose: This study is to derive energy demand and solar power generation potential through CEA(City Energy Analyst) modeling for mixed type apartments in Gangnam-gu, where energy consumption is high. Method: For urban building energy modeling, EPW(EnergyPlus Weather) files were used to analyze the building energy demand and potential after installation of solar panels through CEA modeling. In the case of building energy and solar panels, solar radiation and energy-use types are derived for each building through the Solar Radiation and Schedule model in the CEA model. Result: The cooling and heating energy of buildings in the study site is greatly affected by ambient temperature and humidity, and it was found that there was a large fluctuation by season due to changes in solar radiation due to dynamics with surrounding building s and building structure.The study site had a mixed type apartment structure, so it was found that the potential for soloar power was high when mainly installed on the east wall. Using the results of this study, it is expected to be used as apreliminary data for stakeholders in future decision-making and research by presenting the necessity of research on building energy structure in cities for efficient building energy consumption and solar power generation.
