Fundamentals of Lighting

Abstract

Fundamentals of Lighting, 3rd Edition, takes an integrated approach to the study of lighting and design. Topics include lighting system basics, lighting and the design process, human factors, sustainability, global issues, regulations, business practices, and the LEED building certification program.

Does furniture comfort impact learning? Examining students’ perceptions about classroom furniture

“…Natural light is often associated with the direct light from the sun ingressing through windows. In contrast, artificial light uses the aid of electricity and lamps, from both a qualitative and quantitative standpoint, to illuminate a building (Winchip, 2017). Winchip states that qualitative artificial lighting creates a lighting design that decreases energy costs, conserves natural resources, and lets occupants of a space function comfortably and feel safe.…”

“…Both natural and artificial light sources have benefits and drawbacks. Some of the benefits of incorporating natural sunlight, i.e., daylighting, into interiors include providing the opportunity for views and ventilation, economic savings, and other psychological and physiological effects on occupants (Benfield et al, 2015;Heschong et al, 2002;Moxon, 2012;Winchip, 2017). Winchip further details that daylighting is excellent for distinguishing important details while performing specific tasks, such as reading, writing, etc.…”

“…Some of the drawbacks to utilizing natural light within classroom settings include increased opportunities for glare, damage to interior finishes and materials, and heat gain in hot weather. According to Winchip (2017), glare can occur within classrooms that offer high contrast between light levels, which can cause eye strain, fatigue, and an overall loss in visual acuity. Given this previous information, classrooms should implement solutions that reduce the amount of glare on occupants' eyes.…”

“…Given this previous information, classrooms should implement solutions that reduce the amount of glare on occupants' eyes. Utilizing window treatments or specifying the architecture to include external shading devices, e.g., awnings, louvers, slats, or roof overhangs, can help reduce the glare from sunlight (Winchip, 2017). In a study conducted in India, Kirankumar et al (2018) created a model of a building to test the solar radiation gain and daylighting of the room.…”

“…Benefits of utilizing artificial light within classrooms include increased control of light levels and opportunities for light layering. Winchip (2017) states that most classrooms are not designed to accommodate the varying levels of light needed for students to take notes in a dark environment. Additionally, giving instructors more control of the light sources in higher education classrooms gives students better opportunities to function during different in-class activities, such as group work or audiovisual presentations.…”
