Ugr

UGR is an acronym that can refer to several entities or concepts. The two most common meanings are the University of Granada, a public university in southern Spain, and the Unified Glare Rating, a numeric measure used in architectural lighting design.

The University of Granada (Universidad de Granada) is a public higher education institution located in Granada, Andalusia. It traces its origins to the 16th century and was established in 1531 by Charles V. The university operates a main campus in Granada and maintains a network of faculties, research centers, and academic programs across arts and humanities, sciences, engineering, health sciences, social sciences, and more. It is a major center for teaching and research, with numerous international collaboration programs, doctoral studies, libraries, and cultural activities. The institution serves a large student body and participates in partnerships with national and international universities to support mobility and research initiatives.

Unified Glare Rating (UGR) is a metric used in interior lighting design to quantify perceived glare from luminaires in a space. It is part of European and international lighting standards and is used to evaluate comfort in offices, schools, hospitals, and other environments. The UGR value is calculated from the luminance of light sources and surrounding surfaces, with lower values indicating less glare. Typical ranges span from roughly 8 to 40, and targets vary by space type, often aiming for UGR values below 19 for general work areas. The metric helps designers balance brightness, visual comfort, and energy efficiency in lighting schemes.
