ENHANCED DAYLIGHTING FOR DEEP-PLAN OFFICE BUILDINGS
This paper presents the preliminary findings of the daylighting performance of an optical light pipe system placed in the ceiling plenum of a deep plan office space (10m x 6m x 3m). The south-facing light pipe system can efficiently deliver daylight at the back of the space; between 5m to 10m from window plane for locations between latitudes 24-66oN-S under clear sky conditions. Two identical large scale models (1:4) were used to assess the daylight performance of the light pipe over long-term periods. Results showed that the light pipe can introduce adequate light levels for visual tasks in office environments in climates with predominantly clear sky conditions. Light levels of 300-1,500 lux can be achieved at the back of the space (24 ft from window wall) for solar azimuths 60o East and West of true South (Northern Hemisphere) or true North (Southern Hemisphere) under clear sky conditions.
