Abstract
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%.
