This paper evaluates the effects of a south-facing doubleskinned facade and a ground-coupled heat exchanger on the annual energy performance of a three story experimental office building (911 m2 floor area) in Korea. The annual energy performance was quantified in terms of building thermal load. The individual and integrated effect of the individual systems on the building heating and cooling loads/demands have been analyzed with a comprehensive building energy modeling system. Additional models have been developed for the ground-coupled heat exchanger and for some aspects of the double-skin system. The results show that the energy saving due to the double-skin and the ground-coupled heat exchanger is about 12 - 23%. During the heating season, the double-skin is more effective than the groundcoupled heat exchanger in terms of reducing the heating demand ; the ratio is 6.3 : 3.7. Overall, the integrated analysis indicates that the double-skin and ground-coupled heat exchanger can reduce the annual heating and cooling demand of this type of building in Korea by about 19%.
