As the global warming problem becomes more serious, the Korean government is putting considerable effort to reduce primary energy consumption and carbon generation by implementing relevant policies. In this study, a small-scale house with a floor area of 114.51 m2 located in Yangpyeong, Gyeonggido, Korea was selected to study the effect of window wall ratio on cooling and heating energy consumption, energy cost, and construction cost. Cooling and heating loads and energy consumption in consideration of the window design were analyzed using PHPP, an energy balance, and a passive house planning tool. The height of the east side window was fixed at 3.89 m, while the width was changed to the present Base and two alternative designs. The window areas were 18, 12, and 6 m2 for Base, ALT-1, and ALT-2, respectively. Temperature, humidity, and infiltration were measured for PHPP input values. When the window areas were reduced by 33% and 67% relative to the Base, cooling and heating energy per unit floor area were reduced by only a small amount. Similar results were obtained for heating and cooling energy costs. Our findings indicated that adopting ALT-2, the design with the least window area can reduce the construction cost by 8.5% or 7.764 million won. Therefore, unlike for the energy consumption, much higher construction cost reduction can be achieved with a small window area. This is expected to have a significant impact on the facade design according to the client"s budget in the initial design stage.
