The annual energy demand of the standard rural house models Nongrim-10-26 -ga was analyzed using the DesignBuilder. Size of window and type of window were selected as simulation parameters. As a result, heating energy demand was 8.3 times higher than cooling energy demand and reducing heating energy demand is important factor in reducing total building energy. When increasing window glazing size, internal heat gain and loss was changed depending on the outdoor weather conditions. Cooling energy demand increases in summer and heating energy demand increases in winter. When the type of window was changed, cooling energy demand was decreased as the SHGC value was decreased. However, heating energy demand was changed depending on both of the SHGC value and U-value of the selected window type.
