effect of interior partitioned layout on daylighting energy performance in office buildings
xiv, 149 leaves : illustrations ; 28 cm.
In this age of "Information", many people consider it a deterrent to information flow to provide a hierarchy with private rooms in a modern office layout. There are others, however, who insist that visual and acoustical privacy are more important than any other design factor in achieving higher productivity. The debate may never end, but the partitioned open plan, which is a new form of the vast open plan, has merits of each concept - open and closed layout. Consequently, office design has dramatically shifted to partitioned open planning, with shorter, temporary walls or partitions, originally intended for increasing privacy and diminishing hierarchy, still keeping flexibility in spatial organization. The introduction of low-level partitioned spaces in office layout, however, produces a complicated lighting design problem. Modem office buildings will make growing use of natural daylight illumination to improve lighting quality while reducing energy costs. Consequently, accurately predicted daylighting performance data are needed not only for daylighting design but for artificial lighting system design. Scale models of 12 sets of unit partitioned spaces are constructed and extensive scale model measurements of both daylight and reflected sunlight have been performed within an artificial sky simulator. The prototype building interior is modeled with different partition configurations, each of which is modeled using the different envelope geometry and exterior configurations and then the variations in interior light levels are estimated. This measurement represents the daylighting and reflected sunlight performance results in terms of Daylight Factor (DF) and Reflected Sunlight Illuminance Ratio (RSIR). As a result, partitioned spaces employed in an open plan of modem offices still offer a large potential for daylighting and energy saving as well. Much of the savings may derive from the cumulative effect of reflected sunlight. Optimal design for building envelope geometry and exterior configuration promises additional savings. These obvious advantages of introducing daylight for general illumination of a partitioned open plan have not translated into significant penetration of efficient lighting designs. Proper analysis and a design process that includes both general and specific considerations on illuminance with a partitioned open-plan may be the best formula for success.
