Enclosed internal corridors are long circulation areas with no window provisions, and they require electric lighting to be switched on for 24 hours continuously to operate. Depending on the designs, some corridor designs have openings for daylight at the ends, while others supplement daylight at the middle. Most parts of these corridors, however, are usually dark and consuming a lot of non-renewable energy from artificial light. This research explores how enclosed internal corridors could get the benefits of daylight depending on the corridor wall designs. It explored how %DF (Daylight Factor) less than 1%, especially in Malaysia where the skies are bright, could still be beneficial and useful. The standard illumination required for corridors is benchmarked. Fieldwork for %DF measurements was conducted in selected points at an enclosed corridor of a hostel building on a typical overcast day.
