Abstract

This study aims to analyze energy consumption based on physical environmental changes and the occupancy evaluation of remodeled buildings to suggest improvements for future planning of building-specific designs involving the next public buildings green-remodeling projects. Based on the 2020 Green-remodeling Chungcheong Regional Platform, 19 buildings in charge of energy evaluation were examined; desk research. architectural drawings, data analysis, field investigation, energy analysis using ECO2-OD, and surveys conducted on employees from June to November 2021 were analyzed. The results of this research indicated the primary energy consumption reduction rates of target buildings were 0.2-51% with an average of 26.0%; the average green house gas emission reduction was 6,247kgCO2eq, which confirmed the necessity of green-remodeling projects. However, there were large differences in energy saving rates and cost efficiency according to design and construction of building remodeling. The core contents that should be reflected in the next remodeling planning and design process involve the whole building rather than partial remodeling, green-remodeling items should be selected by prioritizing cost efficiency based on the environmental performance of each building and equipment replacement should be selected after reviewing whether it is suitable for each specific building.
