Analysis of Consumption Patterns by Energy Source in the Apartment House with District Heating System Using the K-apt Data and the AMR Data

The world is currently facing energy and environmental problems. Building sector is accounting for 22 % of the total energy use in Korea. Also, apartment houses account for 45 % of the total energy use in residential buildings. Five utilities that is causing energy consumption in the residential building are electricity, heating, hot water, water, and city gas. In this study, the annual and daily consumption patterns of five utilities were analyzed using the management cost data of K-apt(apartment housing management information system) and AMR(Automatic Meter Reading) data of a A-apartment in Suwon. According to K-apt’s data, the average annual utility fee of 60 apartment complexes that use district heating system is the order of electricity bill > heating bill > hot water bill > water bill, except for city gas for cooking. As a result of analyzing the electricity consumption of a A-apartment located in Suwon city, the base load which is always consumed regardless of whether the resident is active or not is more than 65% of total daily electricity consumption. Therefore, it is very necessary to reduce the base load in order to reduce electricity consumption in apartment houses.
