“…As mentioned earlier, the use of vertical illuminances to control dynamic glazing to were thoroughly studied by Giovannini et al [42,51]. In this study, vertical illuminance values for all four occupants (height = 120 cm, side view directions, perpendicular to the window) were simulated in Radiance using the three-phase method.…”

“…For the external surfaces, the outdoor temperature was considered as well as total radiative gain including direct and diffuse radiation received on the external surface and longwave radiative heat exchange to the surrounding buildings and sky. For internal surfaces, the connection to the adjacent rooms was assumed glazing to minimize glare and the relevant thresholds that could be used were also studied by Giovannini et al [42,51].…”

Dynamic façades play an important role in enhancing the overall performance of buildings: they respond to the environmental conditions and adjust the amount of transmitted solar radiation. This paper proposes a simulation-based framework to evaluate the energy and comfort performance of different control strategies for switchable electrochromic glazing (EC). The presented method shows the impact of a model predictive control (MPC) on energy savings and on visual and thermal comfort for different orientations compared to other strategies. Besides manual operation and conventional rule-based controls, the benchmark in this study was a simulation-based control (multi-objective penalty-based control) with optimal performance. The hourly results of various control cases were analyzed based on the established performance indicators and criteria. The cumulative annual results show the capabilities and limitations of each control strategy for an EC glazing. For a temperate climate (Mannheim, Germany), results showed that an MPC for EC glazing provides visual and thermal comfort while saving energy of up to 14%, 37%, 37%, and 34% respectively for facing north, east, south, and west relative to the base-case.

“…The disability glare is wellestablished in literature whereas discomfort glare is not fully understood [34]. Discomfort glare depends on individual characteristics according to gender, age, fatigue status, light sensitivity, mood [64,65] and diseases, such as glaucoma [66]. Therefore the numerous variables to consider and the lack of standardized measurement makes evaluation of discomfort glare complex [67].…”

Reviewing the Role of Outdoor Lighting in Achieving Sustainable Development Goals

The Sustainable Development Goals (SDGs) aim at providing a healthier planet for present and future generations. At the most recent SDG summit held in 2019, Member States recognized that the achievements accomplished to date have been insufficient to achieve this mission. This paper presents a comprehensive literature review of 227 documents contextualizing outdoor lighting with SDGs, showing its potential to resolve some existing issues related to the SDG targets. From a list of 17 goals, six SDGs were identified to have relevant synergies with outdoor lighting in smart cities, including SDG 3 (Good health and well-being), SDG 11 (Sustainable cities and communities), SDG 14 (Life below water) and SDG 15 (Life on land). This review also links efficient lighting roles partially with SDG 7 (Affordable and clean energy) and SDG 13 (Climate action) through Target 7.3 and Target 13.2, respectively. This paper identifies outdoor lighting as a vector directly impacting 16 of the 50 targets in the six SDGs involved. Each section in this review discusses the main aspects of outdoor lighting by a human-centric, energy efficiency and environmental impacts. Each aspect addresses the most recent studies contributing to lighting solutions in the literature, helping us to understand the positive and negative impacts of artificial lighting on living beings. In addition, the work summarizes the proposed solutions and results tackling specific topics impacting SDG demands.

“…A new set of 'dynamic' daylight metrics have been defined, such as the Annual Light Exposure ALE [46][47], the Daylight Autonomy DA [48], the spatial Daylight Autonomy sDA 300,50% and the Annual Sunlight Exposure ASE 250,1000 [49], the Useful Daylight Illuminance UDI [50], and the Daylight Glare Probability DGP [51]. Besides DGP, also the vertical illuminance at eye-level is used as a proxy for glare analyses [52]. It is worth stressing that above metrics, except ALE, are defined based on 'thresholds', as they represent the percent of occupied annual time when illuminance lies in a certain range.…”
