“…Different illuminance thresholds are associated to the different building typologies and kind of uses of spaces in a building. In a typical office use, the European standard EN 12464-1 [77] and most authors suggest a reference value of 500 lx evaluated on the work-plane [78][79][80][81]; while others consider sufficient 425 lx [6] or even 300 lx [82].…”

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.

“…Light levels were calculated in the vertical plane to imitate light hitting the cornea of the eye and were simulated for two locations (variable 6 in Table 1; the two points are shown in plan in Figure 1c) to model an occupant walking back and forth in the space. [48] -defined as the percentage of occupation time a given illuminance threshold can be achieved by daylighting alone -was chosen as the reference metric for analyzing light penetration and distribution patterns over time and space because it is by definition based on a minimal illuminance threshold and because it can provide a synthetic (single number expressed as a percentage) evaluation of annual, climate-based daylight performance that can account for blind control [49].…”

“…One caveat related to this study is that the use of dynamic shading systems has not been addressed thus far even though methods to model the use of movable shading systems have been proposed in the past [Reinhart 2004;Haldi & Robinson 2010;O'Brien et al 2013]. The reason for this shortcoming is that it is doubtful whether students and or in fact any non-expert visiting a space for a single time could possibly predict the implications of a shading device and control situation over a whole year.…”

In recent years climate-based metrics, in particular daylight autonomy, have found their way into North American standards and green building rating systems. The authors showed in an earlier pilot study that subjective space evaluations by architecture students correlated well with daylight-autonomy-based daylit area simulations in a single north-facing studio space in Boston. For this manuscript the authors collaborated with educators at 11 schools of architecture and applied the method consistently to 13 spaces within the participating schools. The schools are located in Brazil (2), Canada (1), Egypt (1) and the United States (7). The authors also introduce the concept of a "partially daylight area" metric based on a minimum illuminance threshold for daylight autonomy of 150lux. The two metrics correctly determined in 18 out of 24 cases which parts of the study space are fully or partially daylit. The authors accordingly propose a two-tier evaluation system to rate the daylight availability in spaces.
