The purpose of this paper is to address a project for lighting an old town in Italy. Its originality lies in the holistic approach that aims to fulfil several objectives. One is to reduce energy consumption by using efficient lamps and advanced control systems; the second one is to make the network viable and useful for many purposes by integrating ICT devices; the third one is to provide a new identity to the older part of the city by using new technologies and design concepts; while the last one is to ensure street and pedestrian safety according to codes and standards.

The plan of the city of Bagheria and the stock of luminaires of the city are analysed. A multidisciplinary approach has been adopted in order to: analyse the existing lighting infrastructure highlighting critical areas; design a new displacement and select typologies of luminaries able to provide proper light quality and distribution; propose an aesthetic solution and technical design for relevant historical building; and to include in the design process the concept of a new multifunctional pole. Together with an analysis of social benefits, an assessment of economic costs and benefits are discussed.

The project allows good energy savings, meets the standard requirements and gives a relevant and strategic improvement in social and environmental management of the city.

The work provides an example of integrated design of street lighting infrastructures for urban renovation in old cities in degraded environments.

This study focuses on urban lighting design, exploring its effect on citizens´ emotions. A methodology based on Kansei engineering is developed in response to the question: How does lighting of facades within the urban space influence people’s emotions?

Outdoor lighting design is a multidisciplinary topic that involves, among other aspects, design, energy savings, protection of nocturnal biodiversity and profitability, all of which are important functional and regulatory requirements. However, they do not necessarily consider user needs, which make perception and emotional response difficult parameters in the lighting design process. The studies carried out on lighting and its impact on emotions have mainly been done indoors. The objective of this work is to propose a methodology to evaluate emotional response to the illuminated nocturnal urban space with the purpose of providing knowledge to create emotionally efficient luminous spaces that improve people’s perception and well-being. The instrument used was the survey (online questionnaires), based on Kansei engineering, created to incorporate the emotional variable in product design. The research was carried out with participants from Peru, Spain and Germany. The results collected the reaction of the participants to different types of night-time luminous spaces presented, which contributes to a better understanding of user needs and activities regarding the space. This knowledge is intended to help designers meet their expectations.

The Kansei engineering method has made establishing relationships between the sensations experienced and the physical characteristics of the luminous space possible. From the point of view of outdoor lighting design planning, Kansei methodology can contribute to a better understanding of user needs within the urban space, serving as a guide to specialists when making lighting decisions and thus meeting their expectations. Therefore, it is considered a very useful and recommended instrument not only from the beginning of lighting projects but also applicable to lighting master plans. The method used contributes to a multidisciplinary design approach, performing a simultaneous analysis of all the requirements and design parameters (architectural, psychological, biological, environmental and social) that intervene from the first design phases of the project, which will allow qualitative lighting solutions aimed at user satisfaction with the urban night space. From a comprehensive point of view, the instrument generated enables identifying not only quantitative values of the urban night space (luminous spaces and technical descriptors) but also qualitative values (aesthetic descriptors), which are both decisive instruments when measuring user satisfaction.

Participants were only from Germany, Peru and Spain.

Traditionally, research aiming at user responses to lighting environment comes from the field of psychology or engineering, not considering parameters of lighting design that could effectively cater to specific user needs.
