“…To solve the problem, we can be inspired by the process of floodlighting designing [16]. The purpose of floodlighting is to obtain a specific distribution of luminance on the illuminated facade, understood as brightening of certain parts of the facade.…”

“…In order to obtain such an effect, we select luminaires with an appropriate power and an appropriate luminous intensity distribution, place them in the right places and aim accordingly. Observation of the effect allows us to accept a given solution or to introduce some changes (no matter whether we are dealing with field trial or simulations) [16]. We can do the same when designing individual components of the optical system.…”

In the paper, an effective way to design asymmetrical optics for a uniform vertical surface illumination was presented. Assessment of the obtained distribution of luminance (illuminance) on the illuminated surface is done almost at the same time as designing the optical system elements. Advantage of the final application of the presented method in 3D will be independence from the implementation of time-consuming simulations in order to verify the already designed optics. Understanding the method and its application is simple and intuitive. Observing the luminance distribution, created on the illuminated surface almost at the same time as its design, allows to see the effect of adding the next elements of the optical system on this distribution.

“…20 Moreover, there is an important problem for modern lighting technology, which is light pollution. 27–32 This has to be recognised as an interdisciplinary problem, which has an impact on every living organism, in ways that sometimes cannot be imagined. 33–37 Therefore, floodlighting must be assessed both in terms of light pollution and in terms of the issue of glare.…”

The main aim of this work is to present a new method of floodlighting – the ‘Layered Method’. It has been possible to create this method due to the rapid development of linear luminaires with LEDs. When luminaires are located a very short distance from an illuminated wall and are directed at a low angle, the layered floodlighting method gives an unusual and interesting visual effect. In this situation, the length of light distribution on the illuminated wall is the same as the length of the light line and is rather short in width. This gives the opportunity of creating the effect of a layer of light, which can be used, for example, to illuminate Renaissance tenement houses and all types of longitudinal architectural details, such as tympanums or balusters. This paper presents the state-of-the-art use of the layered method of floodlighting. All advantages and disadvantages, in terms of lighting technology and architecture, are carefully described. The ideas contained in this paper could be useful for those who are interested in making architectural objects more beautiful by means of illumination at night-time.

“…In contrast, the lighting design of vegetational areas aims to attract users even at night and ensure safe places [12,13]. Lighting needs to be properly balanced so the user can perceive places correctly [14]. In this scenario, advanced digital tools, such as virtual reality (VR), have enabled the management of lighting design, the verification of design parameters [15][16][17][18][19],…”

Green areas and parks are places where people’s quality of life improves, places of recreation and relaxation, in which to carry out various social activities. Among these, the historic gardens represent the union between green areas and historic architecture. Light is considered one of the main factors influencing the perception of such spaces at night; therefore, lighting solutions should be properly balanced. Immersive virtual reality is a tool that allows for lighting design management from different viewpoints. This study investigates how the lighting of a monumental garden affects people’s perception of its architecture at night. With this aim, a detailed 3D model of the western part of Escorial’s monumental complex in Spain was built in DIALux evo 11 and Unreal Engine 4.27 and used to propose six different lighting scenarios. Participants viewed the scenarios through a head-mounted display and provided subjective feedback on the perceived light strength of the environment and architecture. Results highlight that illuminating surrounding areas affects the environment and building perception, as well as the order in which elements capture observer attention. In particular, lit elements between the observer and the façade can reduce façade importance.
