| Abstract |
In South Korea, the building efficiency certification classifies building energy levels based on their required primary energy. The required primary energy for the building is calculated based on the design drawings on the energy of the system equipment. However, the required primary energy calculated based on equipment in the design drawings is different from the measured required primary energy. Therefore, the measured required primary energy should also be evaluated when calculating the building energy efficiency level. In order to evaluate the measured required primary energy, it is necessary to analyze the actual energy usage of the building. Therefore, this study conducted an analysis of the actual energy usage of small-sized apartment buildings, which have recently increased in number. To achieve this, heating and electricity usage in apartment buildings usage was measured. This study analyzed the heating and electricity usage according to the area of apartment buildings, the number of residents, and the age of residents. As a result, heating and electricity usage of apartment buildings showed energy usage characteristics according to the area, the number of residents, and the age of residents. |
