Indoor temperature in perimeter spaces on warm humid tropical courtyard housing model

In general, Indonesia housing provides open space at front and fence. Open space inside that expose to sky is predicated as inner courtyard. Housing provide open or green space on side rarely. In humid tropics, high temperatures most of the year have an effect on thermal comfort. To fulfill thermal comfort, a housing model with inner courtyards on side and fence is proposed. In this case, representation of warm humid tropic is Surabaya. Simulation method is used to predict indoor temperature of spaces in perimeter courtyard. Spaces located on inner courtyard perimeters are living room, bedrooms and kitchen. These rooms have duration of occupancy more than one hour. With the existence of these inner courtyards, inhabitants can connect with green open space. The result show, on the hottest month, side and fence of inner courtyard model could support indoor temperature. For 14 hours, living room and bedrooms in thermal neutral zone. Except kitchen, only for 4 hours in thermal neutral zone.
