ABSTRACT

ETFE is known as ethylene tetra-fluoroethylene, which is a highly durable polymer material with excellent light transmission properties. The growing adoption of this emerging lightweight material in building construction can be attributed to its inherent characteristics, including its high daylight transmittance, energy-saving potential, and reduced weight in comparison to conventional glazing glass solutions. This paper intends to assess the performance of different frit patterns of ETFE foils as building facades on the distribution of natural daylighting and illuminous environment within the buildings. The research methodology involves a combination of on-site monitoring of selected case study building and physical lab test to ensure a comprehensive research approach. Analysis focuses on key parameters which included the outdoor and indoor lighting level measured in unit of lux and daylight factor to determine the performance for different frit patterns of ETFE Foils. The major findings of this research show that 16mm dots fritted ETFE foils contribute to the most optimal daylighting performance among 4.3mm dots fritted and clear ETFE foils. Understanding daylighting performance of different frit patterns of ETFE foils helps architects and designers on the selection, customization and application of fritted ETFE Foils as building facades. The research outcomes will provide broad insights to the growing body of knowledge on integration of fritted ETFE facades to enhance the overall daylighting performance, quality of indoor illuminance environment and well-being of building occupants.
