A Case Study of the 24hours Public Building in Relation to Energy Consumption and Improvements of Remodeling – Focused on Fire Station Facilities -

Building energy consumption in Korea accounts for 20% of the total energy consumption, and this figure is on a continuous increase. About 71% of the buildings in Seoul are over 20 years old, indicating that the government should present a plan to activate remodeling for existing public buildings. Business facilities account for most of the public buildings managed by Seoul, and as a result of examining the distribution of the total floor area, it was found to be the most suitable for remodeling. Most of these business facilities are fire station facilities, and as fire station facilities consume energy 24 hours, great improvement can be expected when remodeling old buildings. Most of the energy consumption patterns of fire departments showed similar patterns in winter and summer. However, there was no significant difference in energy consumption between the fire stations in the 80s and the fire stations in the 00s. Therefore, Field measurements were carried out, and the reason why there was no difference in energy consumption was found through indoor environment and PMV results, indicating that the older the building, the colder it is in the winter. It is judged that the amount of energy used is limited according to the guidelines of the government and local governments, and through this, the indoor environment is maintained differently depending on the age while consuming a similar amount of energy. In addition, the improvement effect of remodeling was analyzed through the ECO2 program for buildings in the 1980s. It is expected to cost about 1.9 billion won to make the energy efficiency rating 1++, indicating the need to compare it with a dynamic simulation tool that can consider the behavior and patterns of occupants in the future.
