    Evaluation of LEED Interior Design Environment to Improve the Indoor Environmental Quality Through Enhancing Lighting Parameters of UAE Campus Buildings
    (The British University in Dubai (BUiD), 2023-11) HASHAYKEH, HANAN A.; Dr Hanan Taleb
    This study investigates the integration of interior artificial lighting, daylight, and quality views, all of which fall under Indoor Environmental Quality (IEQ), a key LEED (ID+C) credit in interior design environments. The research focuses on a campus building in the UAE, specifically the British University in Dubai. Effective design of these variables can enhance visual comfort and improve the building's indoor environment, including lighting quality and user performance. The methodology combines online surveys, field measurements, and computer simulations using DIALux EVO 11. It also considers human factors among students and staff through a mixed-method approach to validate findings and correlate data. The study aims to connect objective and subjective assessments of environmental factors in both daylight and artificial lighting, including lux value, uniformity ratio, glare, and daylight factor, according to EN 12464-1 (2021) standards. Field measurements validate outcomes from the base model in the software. The research offers practical insights into enhancing IEQ in campus buildings through various lighting strategies and scenarios. It analyzes different spaces based on LEED classifications, such as auditoriums, classrooms, libraries, and administration areas. The key findings emphasize the need to balance lighting parameters and conditions to achieve optimal results. The results show improved lighting conditions, enhanced lux values, glare reduction, and balanced light distribution across various spaces, benefiting user experience and performance. For instance, in the corridor areas, the lux value met the target value, ensuring the desired lighting quality. In other locations, such as the auditorium and classroom FF-111, lux values significantly exceeded the target levels, with values reaching 527lx and 602lx, respectively, greatly enhancing overall lighting conditions. The study's actionable insights cater to designers, architects, and stakeholders involved in campus building projects in the UAE. By integrating sustainable standards, this research promotes environmentally sustainable indoor environments that prioritize occupant well-being and enhance the quality of educational spaces.
