Due to the global warming and the gradual increase of costs for energy generation, new buildings aim high energy efficiency. At the same time, the thermal comfort has to be maintained. To achieve these requirements, a building has to contain and energetically optimized architecture, uses thermally optimized building construction and contains a well controlled and efficient plant system with focus on the use of sustainable energy. A Zero Energy Building is a building with reduce the building energy demand through passive & active technologies and supply energy to building through renewable energy to maintain net-zero energy balance.
In order to evaluate the possibility to maintain the thermal comfort environment and simultaneously to achieve the building energy reduction performance targeting Korean apartment building, we calculated the building energy demand by passive design through using the dynamic thermal simulation carried out with the dynamic thermal simulation program TRNSYS16.1. As a result, the resulting annual energy demands are 71kWh/m<SUB>2</SUB> for heating, 15kWh/㎡ for cooling and 14kWh/㎡ for dehumidification by strengthening infiltration. If in a second step the thermal bridges are reduced, which brings down heat energy demand further. Also the energy demand for space heating decreases significantly when the insulation thickness is increased from 8cm to 15cm. But the next step to 20cm and triple glazing makes nearly no difference, because the better insulation is outweighed by lower solar gains through the triple glazing in winter. Contrary to the heating loads, the cooling load rises, because higher insulation levels prevent a cool down in case of lower ambient temperatures overnight.
