Shining a Light on Sustainability, Enhancing Interior Lighting Performance in UAE: A Case Study of Ajman University.

Abstract

This study explores the prevelance and impact of light pollution indoors at Ajman University, UAE, with particular reference to its implications for health, productivity, and energy efficiency. While light pollution outside has gained much notice, the academic interior is less understood, particularly in hot and arid environments like the UAE. Utilizing the mixed-methods approach field measurements, surveys with students, interviews with faculty, and DIALux simulations the study evaluates the performance of lighting in prominent academic spaces such as Labs, studios, and corridors. Outcomes recognize serious inefficiencies such as poor illuminance (e.g., 120–160 lux in studios vs. the optimal 300–500 lux), uneven light distribution, and excessive glare leading to eye strain, fatigue, and compromised academic performance. Energy audits recognize power densities for lights reaching 16.51 W/m² in some areas. Design suggestions LED retrofitting, daylighting integration, and smart control have the potential for savings of 30–50% with increased visual comfort. Such measures align with the UAE Vision 2050 sustainability targets and provide an example for universities to follow people-focused, energy-efficient lighting schemes. Closing the gap between technical performance and occupants' wellbeing, this research offers a model for enhancing the lighting in learning facilities in arid environments, resulting in healthier and sustainable learning environments.
