“…Using this lighting method, a lot of attention has to be placed on preserving the horizontality and verticality of the architecture. Skar ży ński et al [40] used the accent method to enhance the Belweder Palace, home of the President of Poland. The design idea was to highlight both sides of the façade with recessed wide beam spotlights placed in front of the structure, as well as the balustrades in the roof and the gable through small narrow beam spotlights.…”

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.

“…Figure 5 shows a simplified model of the light environment, which became the basis for developing a simulation model in specialized graphics software in the next step. Another problem to consider is the size and location of the light spot on the facade surface, where according to current recommendations and requirements of ULOR ( [32,33] the luminous flux of outdoor lighting fixtures should be entirely directed into the lower half-space [26,27]. ULOR-Unified Glare Rating (ULR) is a measure used to quantify the discomfort caused by glare.…”

“…Reducing light pollution is an important issue in outdoor lighting [24,25]., Scientific papers published on the aforementioned topic show the technical possibilities of reducing the above phenomenon while increasing the energy efficiency of the lighting system. Article [26] presents the concept of a design algorithm for quantitative evaluation of illumination, enabling the minimization of energy losses of the lighting system and the reduction of the light-pollution phenomenon, while article [27] defines new parameters defining the use of the lighting system.…”

The article presents selected results of research related to the use of outdoor lighting, mainly street lighting, in the design of facility illumination. The indicated subject matter primarily concerns architectural structures that are located in urbanized city spaces and in the strict centers of old cities. It is in these areas that there is usually a significant saturation of historic secular and sacred buildings with significant tourist values. At the same time, the immediate surroundings of the structures are usually wrapped by a dense network of street lighting infrastructure. This illumination can be a major setback in the process of illumination planning. Therefore, it is necessary to take into account the extent of this impact on the planned illumination work, related to the selection, mounting, and direction of illumination equipment. This is related to the distance of the street luminaires from the facade, the height of their installation, the distance of the poles from each other, the power of the street luminaires, and the luminous flux distribution of the luminaires used. The purpose of the work undertaken was to analyze the extent to which outdoor lighting influences the planned illumination of an architectural structure and to explore the possibility of its potential use as a component of illumination. Analytical work was conducted at two levels of detail using advanced graphical computer applications. After general considerations and the derivation of conclusions, an example of illumination of a large sacral building was realized successfully using the element of street lighting as a component of illumination.

“…The designer does not pay much attention to this issue, because the main goal is to achieve an aesthetic effect. After developing the concept of illumination, a classic electrical design is generated in which these parameters are analysed [12,13]. Then, the lighting and control systems are selected.…”

This article describes a system for designing floodlighting of objects using computer graphics. Contrary to the currently used visualisation tools, the developed computer application is based on the daytime photography of the object and not on its three-dimensional geometric model. The advantage of the system is the high photorealism of the simulation, with no need to create a collage of visualisation with photography. The designer uses the photometric data of luminaires, and their photometric and colourimetric parameters are defined. With the system it is possible to perform a precise lighting analysis—the distribution of illuminance and luminance—both for the entire facility and in any plane or point. The system also analyses the total installed power of a given design solution. The system application is presented as an example in the form of a case study. This example shows the features of the system and further expected directions of development.
