A toolbox to evaluate non-residential lighting and daylighting retrofit in practice

Research output: Contribution to journalArticle


In the field of lighting and daylighting, standard monitoring procedures to assess the overall performance of retrofit projects are scarce. Nevertheless, access to monitored data is crucial in assessing whether daylighting or electric lighting systems deliver the expected performance in terms of cost-effectiveness, energy efficiency and lighting quality. In order to bridge this gap, a lighting retrofit evaluation toolbox was developed as a part of the International Energy Agency − Solar Heating and Cooling Programme (IEA-SHC) Task 50: “Advanced Lighting Solutions for Retrofitting Buildings”. The evaluation toolbox focuses on non-residential buildings and covers four key aspects: energy efficiency, costs, quality of the lighting environment and user satisfaction. This article presents the main features of this evaluation toolbox, along with some lessons learned from its application in selected case studies.
