Increased energy prices and trying to decrease environmental loads have created many efforts to reduce the amount of energy consumed in buildings, and currently many nations are actively conducting research on passive houses, low-energy buildings and zero-energy buildings. On the other hand, the 2012 EXPO had been held in Yeosu, South Korea from May to August 2012, so this study will monitor energy consumption, which is going to be used for the period, targeting the Korea Exhibition, built with the concept of low and renewable energy. The building is located on the south coast of South Korea that usually shows high temperatures and humidity over seasonal changes and summer during the exhibition. The heat transmission coefficient of the outer walls and windows is designed as 0.15W/m2K and 1.8W/m2K respectively to minimize energy consumption and a geothermal heat pump is introduced as a key heat source to improve the energy efficiency of air conditioning. In addition, the power generation facilities are using renewable energy, including two 50kW hydrogen fuel cells, a 200kW photo voltaic array and a 6kW wind power generator, in order to enhance the self-reliance level of the building site. A simulation-based calculation using DOE-2 will be conducted in order to estimate the energy consumption during the exhibition and although the energy consumption could be seen as different according to usage case, it is shown as 485 to 547MWh/year and the energy production as 501 to 548MWh/year, thus zero energy consumption in the building site is expected to be carried out during the operation phase. |
