“…The present research is part of a more comprehensive study that focuses on the lighting of neoclassical buildings and aims to combine criteria for light pollution, energy consumption and aesthetic preferences when selecting luminaires for the illumination of façades [12][13][14][15][16][17][18][19][20]. For this purpose, a method was developed, which combines data from different types of luminaires and different placements on specific elements of the façade of neoclassical buildings and provides visual information and data on the resulting lighting characteristics.…”

Light pollution is a phenomenon that affects both humans and the environment negatively. Currently there are no established means to calculate light pollution. This work proposes a method for calculating the levels of light pollution on the facades of buildings, specifically historical buildings, which are the most difficult to light, using simulation techniques. The proposed methodology tested different simulation grid densities and concluded that the highest density produces most accurate results, since lower densities are prone to software errors. Moreover, this research proves that the visual perception of a lit façade is the wrong way to determine if a lighting design produces light pollution and that the comprehensive methodology proposed should be used to determine the percentage of light that spills into the environment.

Outdoor lighting design consists of many different objectives, depending on the area that is illuminated. In addition, besides functional lighting, extra messages may be superimposed to a lighting configuration. This adds to the complexity of the lighting design. Furthermore, temporal variations in lighting may be used as an additional tool of expressivity. All the above require some basic training and also some familiarity with expression tools. In this work, a framework is given for seamless communication through lighting, including both spatial and temporal lighting patterns. To this end, two different kinds of time scales are considered, leading to case studies for both seasonal lighting and communication through rapid spatiotemporal differentiations in it. The framework is two-fold, allowing for both diagrammatic and quasi-algebraic elaboration, leading to interesting visual results and providing the first step towards optimization. Different cases of outdoor lighting are considered as case studies, namely façade lighting and glass cases. These are used to illustrate the applicability and the added value of the current framework, that is, the systematization of the lighting procedure taking into account artistic interventions, which can be considered an extension of utilizing semantics.
