This study evaluated natural lighting performance of Kwangajeong, the traditional housing in South Korea. Window-to-wall ratios were calculated by using the drawing documents. Daylighting factors were determined by field measurement. The results indicate that daylighting factor of the Kwangajeong is slightly low comparing present sustainable building design guide in South Korea even though the window-to-wall ratios are relatively high. It is thought that the relatively low daylighting factor are resulted by the low transmittance of Changhoji, the paper used on windows and Cheoma, eaves of the roof.
