초록

This study aimed to analyze the improvement effect of thermal performance and indoor thermal environment by green remodeling project of public buildings and to suggest consideration for green-remodeling project plan and design in the aspects of thermal performance and indoor thermal environment. The subjects are 19 buildings based on the 2021 Green-remodeling Chungcheong Regional Platform. For these purposes, energy analysis using ECO2-OD, visiting field measurements of indoor thermal elements and survey on employee were conducted. As a result of thermal performance analysis, it was found that the improvement of thermal performance of old buildings based on structural insulation reinforcement can have a definite effect on reducing building energy consumption. In evaluating PMV calculated by measured data, 65% of buildings were in the comfort range based on the ISO 7730 standard. As a result of the subjective response of facility occupants to the indoor thermal environment before and after green remodeling, the thermal sensation about after the green remodeling changed positively or not changed in 89% of the buildings. The humidity and radiation sensation changed positively or not changed in 83% of the buildings. In conclusion about measurement and survey, the effect of improving the indoor thermal environment after green remodeling was identified.
