The purpose of this study is to provide new design techniques for designers to design energy saving balcony in the apartment house using solar energy passively. These design techniques are examined with some samples of foreign buildings used solar energy passively. To classify these design techniques, this study sorts out the energy saving design elements from the preliminary studies. The results of this study show how to apply each design technique to the design of balcony in the apartment house and present a classification table of these techniques. Finally, this study suggests a design solution which can be applied in the design of balcony in existing apartment house.
