“…This is unfavorable due to the fact that floodlighting design can be characterized by both high energy wastage and high levels of light pollution. This problem can be solved by the implementation of specific calculation and evaluation methods [50,51] as well as by innovative solutions [52]. Despite the fact that there are currently no unified or international standard requirements for energy efficiency and light pollution related to floodlighting, or if there are, these are only local, it seems reasonable to assess outdoor lighting energy efficiency and light pollution using the same parameters as those for outdoor workplaces or roads ( Table 1).…”

This paper presents an attempt at a unified approach for the assessment of outdoor lighting solutions at the design stage. First of all, the lighting criteria for different types of outdoor lighting installations have been carefully described. Despite the differences in criteria, it is possible to find a common ground for the assessment of lighting solutions at the design stage. This is based on the need for the assessment of lighting solutions to be included in the requirements for the luminous environment, light pollution, and energy efficiency. The review and analysis of the standards and reports allows an experimental procedure to be created, the main aim of which is to find the best and most sustainable lighting solution for any outdoor situation. The procedure was tested by the example of an analysis of parking lot lighting solutions. In the case analyzed, 120 solutions were considered. It appeared that, in only 65 cases were the requirements referring to both lighting condition and light pollution met. Finally, based on the lighting energy efficiency assessment, ten solutions were selected as the most suitable. Furthermore, only one solution out of the ten was the most beneficial, taking into account the extra criterion of basic economic cost. The case study confirms that the assessment procedure allows the most beneficial solution to be selected, taking into account the luminous environment, as well as light pollution and energy efficiency criteria. The proposed multi-criteria assessment procedure may be used as a valuable tool by lighting designers to select the most beneficial solution in order to meet the needs of safety, visual efficiency, and comfort, as well as taking into account light pollution and energy efficiency restrictions.

“…Lighting building façades is a technique, known as floodlighting, that appeared at the beginning of the 20th century as a modern abstract art able to cross the boundaries between film, architecture, and painting [95]. The biggest challenge for architectural lighting is to design a decorative illumination that can give a building a different nature than the one it has in daylight, emphasizing its shapes and highlighting the characteristic details of the objects while hiding those that are less interesting [96]. The light is capable of "building" on its own, not only lighting or decorating, but making houses and facades visible, enhancing historic buildings, and emphasizing modern architecture.…”

“…Due to the growing complexity of lighting design, field trials, that use real lighting equipment, can no longer be used. The design of complex lighting systems needs the use of smart simulation software that can provide a realistic virtual representation of the final results [96,100]. Studies observed that some factors, especially related to the subjective response of people, strongly influence the visual perception of lighted buildings.…”

Virtual Reality for Smart Urban Lighting Design: Review, Applications and Opportunities

More and more cities are evolving into smart cities, increasing their attractiveness, energy efficiency, and users’ satisfaction. Lighting systems play an important role in the evolution process, thanks to their ability to affect city life at night along with people’s mood and behaviour. In this scenario, advanced lighting design methods such as virtual reality (VR) became essential to assess lighting systems from different points of view, especially those linked with the city users’ expectations. Initially, the review highlights a list of objective and subjective parameters to be considered for the lighting design of three main city areas/applications: roads, green areas and buildings. Besides, the state-of-art in using VR for outdoor lighting design is established. Finally, the Unreal game engine is used to analyse the ability of VR to take into account the lighting parameters, not yet investigated in current literature and to highlight the VR potential for augmenting lighting design. The results confirm the benefit of using VR in lighting design, even if further investigations are needed to establish its reliability, especially from the photometrical point of view.

“…We can even risk the statement that practically, every design and analysis of lighting use computer simulations. Both interior and outdoor lighting designs are created in virtual space [11]. Designs contain results in both digital and graphic-visualisation form, more or less photorealistic.…”

The current lighting solutions, both in terms of design process and later implementation, are becoming more and more intelligent. It mainly arises from higher opportunities to use information technology (IT) processes for these purposes. Designs cover many aspects, from physiological to including technical. The paper describes the problems faced by any designers while creating, evaluating them, and presenting the final results of their work in a visualisation form. Development of virtual reality (VR) technology and augmented reality, which is now taking place before our eyes, makes us inclined to think how to use this reality in lighting technology. The article presents some examples of applying VR technology in various types of smart lighting designs, for interiors and outdoor objects. The performed computer simulations are compared to reality. Some surveys, in terms of visualization rendering, were carried out. In the article, the current capabilities and main limitations of virtual reality of lighting are discussed, as well as what can be expected in the future. The luminance analysis of the virtual reality display is carried out, which shows that this equipment can be used in lighting technology after the appropriate calibration. Moreover, an innovative lighting design system based on virtual reality is presented.
