Abstract This study analyzes the technology and energy usage applied to the green remodeling project of public buildings in Jeju. As a result of identifying the architectural outlines of 20 health centers and daycare centers and confirming the green remodeling technology, it was found that 2 to 11 technologies were applied to each. The most frequently applied technology was high-performance windows, followed by high-efficiency heating and cooling systems, external wall insulation, and roof insulation. The change in energy usage showed a decrease in 15 locations and an increase in 5 locations, and the average value of energy usage per unit area decreased by 10.74%. It was confirmed that the decrease rate in the middle season was greater than that in the summer and winter seasons. It was confirmed that the seasonal energy usage decrease rate was greater in the middle season than in the summer and winter seasons. In terms of energy change by use, the energy decrease in the winter season was greater for public health centers, and the energy decrease in the summer season was greater for daycare centers. Based on the results of this study, green remodeling can increase energy saving effects if technology is selected considering the building use and seasonal climate conditions. Green remodeling, which reduces energy use, can actively expand both public and private buildings and contribute to carbon neutrality in the construction industry.
