Abstract

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.

24小时公共建筑能耗与改造改进研究——以消防站设施为例
韩国的建筑能耗占总能耗的20%,而且这一比例还在持续上升。首尔市内71%的建筑物的楼龄超过了20年,因此,政府有必要提出对现有公共建筑进行重新改造的方案。在首尔市管理的公共建筑物中,商业设施占大部分,对建筑面积的分布进行分析后发现,最适合进行改建。这些商业设施大多是消防站设施,由于消防站设施24小时消耗能源,因此在改造旧建筑时可以期望得到很大的改善。大部分消防部门的能耗模式在冬季和夏季表现出相似的模式。然而,80年代的消防站与00年代的消防站之间的能耗没有显著差异。因此,我们进行了现场测量,通过室内环境和PMV结果找到了能耗没有差异的原因,说明建筑越老,冬季越冷。根据政府和地方政府的指导方针,判断能源的使用量是有限的,通过这种方式,在消耗相似的能源的情况下,根据年龄保持不同的室内环境。此外,通过20世纪80年代建筑的ECO2项目,分析了改造的改善效果。如果要将能源效率等级提高到1++,预计将花费19亿韩元左右。因此,有必要将其与考虑未来居住者行为和模式的动态模拟工具进行比较。
