Abstract
In 2021, the South Korean government highlighted the Green Remodeling Project for Public Buildings as a crucial initiative for reducing building emissions and tackling post-COVID challenges. Aimed at enhancing energy efficiency and living conditions in public buildings, especially those used by children and the elderly, this project represents a novel approach to sustainable building practices. This research aimed to evaluate the project’s effectiveness and identify areas for improvement using a two-fold methodological approach. Initially, a survey of 1065 buildings undergoing green remodeling revealed their condition and the impact of such renovations. Additionally, simulations predicted the energy savings to be achievable, uncovering an average improvement of 30% across buildings, with variations by region and building use. Public health centers saw the highest gains. Despite these successes, disparities in outcomes highlighted the need for strategic adjustments to ensure uniform benefits. This study suggests a refined strategy to enhance green remodeling’s impact, making a significant contribution to sustainable building practices by addressing both energy saving for carbon neutrality and public health priorities in a post-pandemic context.
