With the change in Earth's ecosystems due to climate change, a number of studies on zero energy buildings have been conducted globally, due to the depletion of energy and resources. However, most studies have concentrated on residential and office buildings and the performance predictions were made only in the design phase. This study verifies the zero-energy performance in the operational phase by acquiring and analyzing data after the completion of an exhibition building. This building was a retention building, in which a renewable energy system using a passive house building envelope, solar photovoltaic power generation panels, as well as fuel cells were adopted to minimize the maintenance cost for future energy-zero operations. In addition, the energy performance of the building was predicted through prior simulations, and this was compared with actual measured values to evaluate the energy performance of the actual operational records quantitatively. The energy independence rate during the measurement period of the target building was 123% and the carbon reduction due to the energy production on the site was 408.07 tons. The carbon reduction exceeded the carbon emission (331.5 tons), which verified the carbon zero and zero-energy performances.

제안 방법
Since this building was aimed to achieve zero energy usage during the operational phase from the beginning, the concept of minimizing cooling and heating loads by increasing the building insulation performance was applied from the design phase. To reduce cooling and heating loads, stronger standards of thermal transmittance for the envelope than those used in the southern region were applied.
This study evaluated the energy performance of actual operation records quantitatively through the comparative analysis between simulation values and energy consumption and production generated in the operational phase in a building from May 14, 2012 through May 15, 2013.
Thus, this study conducted a performance evaluation on a zero energy for the Korean Pavilion, which was to show zero energy use and zero carbon emission in the international exposition held in Yeosu in 2012. The energy performance was evaluated through the renewable energy production collected through the annual energy simulation and monitoring and measured data such as the power received from external sources and the power delivered back to the utility grid.
To predict the annual energy production and usage amounts in the target building, the DOE-2 program was used to conduct simulations. DOE-2 tool is a program widely used around the world to evaluate the energy performance in buildings.
대상 데이터
The purpose of the building was that it was to be used in the Korean Pavilion during the Yeosu International Expo and was where exhibitions and performances were held. It was planned to be utilized as a permanent exhibition hall after the EXPO.
It was planned to be utilized as a permanent exhibition hall after the EXPO. The size of the study target building was a three-story building whose floor area was 3,395㎡ and had a total floor area of 5,242㎡. Its main purpose was as a cultural and meeting facility.
The target building was completed in May 2012 and located in the Yeosu area, which is the southern coastal region in Korea. Figure 2 shows the monthly high and low temperatures and the relative humidity in the region.
성능/효과
The energy usage for each factor was also investigated and the results showed that the energy amount consumed in the exhibition load was the largest followed by cooling, equipment, ventilation, and lighting loads. Approximately, a difference in the cooling load among them between Case 1 and Case 2 was two times, which was due to the large number of occupants as a result of the exhibition performance-related loads.
The error of simulated and measured values of renewable is 0.37%, net energy consumption is -12.46% and energy independence rate is 14.75%.
The study analyzed that the target building supplied an energy capacity of 84kW/m2·year through the solar photovoltaic system, which was slanted at an incline of 10° to the south and exceeded the energy load of the building by 79kW/m2·year.
