IMPROVING THE DAY LIGHTING OF DEEP-PLAN BUILDINGS BY MEANS OF LIGHT PIPING TECHNIQUE: THE CASE OF ARCHITECTURAL STUDIOS IN THE DEPARTMENT OF ARCHITECTURE, UNIVERSITY OF JORDAN
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
This research discussed the importance of daylight as one of the major factors in sustainable architectural design and highlights the significant role of daylight in energy consumption reduction and enhancement of human health and performance due to the unique characteristics of daylight such as; spectral composition, quality, and variability which has demonstrated to make it a preferred source of lighting. A physical 1/20 scale testing model is built in real sky design conditions to evaluate the feasibility of utilizing light pipes to enhance daylight in deep plan studio and to reduce the need for electric lighting. Using the model in outdoor day-lighting condition helped to evaluate the daylight performance of different mirrored light pipe prototypes. The study provides insight about light pipes parameters and evaluated them in order to understand the relationship between those parameters and the amount of illumination delivered. The parameters include cross-section shape, crosssection area, internal angle and collector’s size and inclination angle. The research proved that the light pipe system is the simplest advanced system that allows daylight to transport into the interior spaces where windows are restricted. Five horizontal pipes are sufficient to illuminate the studio by 750 Lux which are recommended in design studios
