This study derived benefits of green remodeling technologies that can be utilized in public daycare centers. Energy simulations were performed using ECO2-OD. Economic feasibility was evaluated using net present value to analyze expected effects of green remodeling. As a result of the analysis, primary energy consumption was reduced by an average of 31%. The average net benefit was -229,592,867 KRW. The ranking of green remodeling technologies was derived by considering energy savings, economics, and user preferences. Their rankings were placed in the order of PV systems, boilers, windows, insulation, air conditioners, ventilation systems, and lighting. Applying green remodeling technology priorities established by this study will allow us to implement green remodeling with higher energy savings and lower costs than current green remodeling consulting results.
