Effect of using different light pipe parameters on the daylight quality in buildings: The case of Jordan

ABSTRACT

The primary objective of this study is to discuss the effect of using different light pipe parameters such as, light pipe’s shape, cross area, and height on indoor daylight quality. In descriptive approach, the integration of light pipes have been overviewed, whereas, a scale room model of 4mx8m introduced to measure the internal illuminance as an empirical approach. It has been evaluated through outcomes that daylight holds undeniable importance in human life. The experiment went through three phases, in order to find the best cross shape of light pipe with best building height. Light pipe with circular shape in first phase achieved an average of 267 Lux inside; within the second phase the circular shape with an average area of 0.44 m² achieved an acceptable average of illuminance of 520 Lux, and within the last phase it is found that illuminance has an inverse proportion with pipe height. Furthermore, in this study Autodesk Revit tool was utilized for the designing of structure and components in the 3D environment. As a result, the daylight utilization has been observed to be beneficial, as it minimizes the utility costs and improves the well-being of building occupants in Jordan.
