Abstract
The purpose of this study is to analyze the state-of-the-art daylighting design among LEED(Leadership in Energy and Environmental Design) multi-family housing cases and to explore the feasibilities for their applications in domestic housing design. Occupants in multi-family houses are reported to consume more electricity power than those in single houses. That may imply the problems of daylighting design in domestic housing design for multi-family houses have better insulation system and less windows and outside walls than single houses. Therefore two systems, daylight delivery system and daylight control system, are scrutinized for daylighting design with LEED cases. The findings show when windows as a daylight delivery system are combined with overhangs, fins, louvers, fenestration materials, speciality fenestration, or interior controls as a daylight control system, the outcome goes with more energy savings and better facade design. Beside those, lightshelves as a daylight delivery system seem to have potentials in domestic multi-family houses with deep plans and less outside walls. Daylighting designs in domestic multi-family houses need to pursue available options more to achieve the integration of energy and aesthetics values.
