The transition to sustainable buildings is a pressing issue, driven by environmental and economic concerns. This study evaluates the energy-saving effects and cost-efficiency of green remodeling elements in public buildings, focusing on daycare centers and health clinics remodeled in 2021 and 2022. The analysis highlights that building envelope improvements, such as enhanced insulation and high-performance windows, offer significant energy savings at relatively low costs, making them a priority in remodeling projects. HVAC and ventilation system upgrades, while requiring higher initial investments, show potential for long-term savings and indoor environment enhancement. Additionally, LED lighting and control systems are identified as cost-effective methods for reducing energy consumption, and renewable energy technologies significantly enhance energy independence and carbon reduction, despite their substantial upfront costs. This study provides a systematic approach to incorporating cost and energy considerations into public building remodeling designs, offering valuable insights for efficient strategy development. It also underscores the need for government support to promote green remodeling initiatives. Future research should focus on exploring the interactions between remodeling elements and external factors to develop more comprehensive and sophisticated analyses.
