When it comes to natural ventilation performance for large space cooling during summer time or intermediate seasons, double skin facade(DSF) integrated with cross ventilation(CV) exhibits more energy efficiency than single-side ventilated DSF. In this case, ventilation performance is remarkably affected by climatic conditions. Therefore, it is important to analyze micro climatic conditions before applying this passive technique.
To date, many studies have been done regarding DSF, however, there are very few studies pertaining to feasibility have existed in Korea. In this paper, a case study of four models with weather data of Seoul was conducted based on the following criteria: existence of DSF, opening/closing modes of the DSF openings, and ventilation types. The results showed that the annual cooling load of the cross-ventilated DSF was less than that of the single-side ventilated DSF by 7.9%, and the ACH of the cross-ventilated DSF was 1.2~6.2 times more than that of the single-side ventilated DSF.
