As there is no method to quantify the adverse effects of facade lighting, lighting designers should assess direct upward light and reflected light during the design process to reduce facade lighting’s contribution to skyglow. This paper proposes a new methodology that utilizes the existing widespread photometric calculation tool in the lighting design industry.

A fundamental understanding of lighting technologies and lighting metrics is recommend for this presentation.

Learning Objectives

  • Identify different facade typologies
  • Characterize the different lighting methodologies relative to facade typology
  • Recognize how lighting analysis software can be a tool for assessing the sky glow generated by facade lighting
  • Compare facade lighting techniques to ascertain their respective contributions to sky glow
