This study aimed to analyze the insulation performance and the efficiency of facility system efficiency of office buildings with building energy efficiency rating 1++ grade or higher, which is a standard of zero energy building certification. For the analysis, 90 low-energy office buildings were selected as the target buildings and ECO2 program data was used. As a result of analysis, increasing the insulation performance in the office buildings is considered to have little influence on the improvement of the grade of building energy efficiency rating. And it is found that the high efficiency of the facility system is advantageous for obtaining the high grade of building energy efficiency rating. This indicates that building energy needs a comprehensive analysis. Although one element is poorly performing, the high performance of other elements indicates that overall energy use can be reduced. As a result of this study, it is expected that office buildings will be used as basic data of energy saving design elements satisfying building energy efficiency rating 1++ grade with the aim of obtaining zero energy building certification.

The contamination of photovoltaic (PV) cells reduces the incidence of sunlight and reduces the power generation output of PV cells. The main factor influencing the contamination of PV cells installed outdoors is the fine dust in the air, but the influence of temperature, humidity, rain and wind can be considered. In this paper, experiments on the contamination of PV cells according to the fine dust density, the temperature and humidity of air were investigated. As results of this study, the contamination area of PV cells increases with contamination time and cumulative fine dust density in the air. The contamination of PV cells increases when the temperature is low and the humidity is high. Also, as the contamination of PV cells is affected to the wind, the deviation of contamination area is happened.
