Contributing to the advancement of lighting research

The studio's practice is grounded in research. Diana Delnegro chairs CIE Technical Committee 4-59, which is developing the international Guide for Lighting Urban Elements, holds a UCL doctorate on the image of the city at night, and has occasionally taught and examined research at several universities.

The CIE and the international guide

The CIE, Commission Internationale de l’Éclairage, is the international authority on light and lighting. It began in 1900 as a commission on photometry and took its present form in 1913. What it produces are the definitions, measurement methods and standards that industry and designers follow worldwide, and its standing as an international standardization body is recognised by the International Committee for Weights and Measures, by ISO and by IEC.

Diana Delnegro chairs CIE Technical Committee 4-59, which is developing the international Guide for Lighting Urban Elements: how monuments, façades, bridges and sculptures should be lit. Once finished it will update and replace the CIE's 1993 guide. Chairing a CIE committee means steering the work of specialists from several countries into a text that becomes a worldwide reference.

She is the first Portuguese person to chair one of the organisation’s technical committees.

Research

The doctorate, completed at The Bartlett, UCL Institute for Environmental Design and Engineering, studied the effect of artificial lighting on legibility and wayfinding in the city at night. That work underpins the atelier’s approach at urban scale.
