“…In non-OECD countries these shares are usually higher". Several other authors report similar values [2][3][4][5][6][7][8][9]. Lighting is moreover responsible for a significant proportion of the maintenance costs in buildings, and most of the current lighting installations (ca.…”

In the last decades, several studies aimed at assessing some specified aspects of visual comfort characterizing the relationship between the human needs and the light environment, such as an available amount of light, light uniformity, light quality in rendering colors, and predicting the risk of glare for space occupants. For each of them, a (still growing) number of indices and metrics have been proposed in literature and standards. In the present work, they are described, categorized according to common features, and finally discussed. As in the case of long-term thermal comfort indices, such visual comfort indices and their summation over a specified calculation period might be used for driving optimization processes to support a more conscious integrated design of buildings. To that purpose, the choice among the available visual comfort indices needs to be informed by an analysis of their features and implications. We present recommendations for use, and suggest areas where improvement is needed for their use in optimization processes to support buildings' design.

“…From field studies and computer simulations, it has been concluded that lighting energy use is correlated with outdoor illuminance. When the outdoor illuminance is above a certain level, people working around perimeter zones with access to natural light are less likely to use artificial electrical lights, and the artificial illuminance needed to meet design illuminance levels is lowered [2][3][4][5][6]. However, other studies have shown that occupants exert a crucial influence on lighting energy use, regardless of illuminance.…”

“…This fact has caught the attention of practitioners, researchers, and policy makers. Studies have shown that the two main factors affecting lighting energy use are outdoor illuminance and occupant behavior [2][3][4][5][6][7][8][9][10]. From field studies and computer simulations, it has been concluded that lighting energy use is correlated with outdoor illuminance.…”

“…The analysis methods and conclusions from these studies [2][3][4][5][6][7][8][9][10] provide some baseline understanding of the role of illuminance on lighting energy use in buildings. However, due to limitations associated with the building layout and limited measured data, the complete picture of lighting energy use and the influencing factors, remains unclear.…”

“…The above studies [2][3][4][5][6][7][8][9][10] on lighting energy use were mostly focused on small office and residential buildings, with the research findings greatly dependent on building layout and daylighting control systems. The analysis methods and conclusions from these studies [2][3][4][5][6][7][8][9][10] provide some baseline understanding of the role of illuminance on lighting energy use in buildings.…”
