Virtual Tours and Representations of Cultural Heritage: Ethical Issues
Get PDFNowadays museums realities are increasingly interested in introducing advanced technological tools, in order to preserve and enhance the Cultural Heritage, as well as to make it more accessible and attractive. In fact, digital tools, such as Virtual Reality (VR) and Augmented Reality (AR), allow to provide effective responses to the needs of different types of users, to enhance the expressive qualities of the cultural asset, as well as to enrich the visitor’s learning possibilities. However, the integration of new technologies in the management of Cultural Heritage involves different type of ethical issues. The paper analyses some of the ethical issues related to ontological, economic, and social aspects, trying to outline some principles able to limit these critical implications

No full textANALYSIS AND DESIGN APPROACH FOR A NOCTURNAL IMAGE OF THE CULTURAL LANDSCAPE
No full textThe current debate on the cultural landscape proposes active enhancement practices and local planning tools that are also dedicated to the study of scenic-perceptive components and visual values. However, the current indications are limited to the definition of day images of sites and are not based on investigations of the corresponding nocturnal images of the widespread heritage. The study presented in this paper is aimed at underlining the importance of the analysis of nocturnal images and at defining design tips and guidelines for the definition of the nocturnal landscape image. The proposal of design guidelines will result from the assessment of the current nightscape. The aim of the paper is to present the methodological approach that has been conceived to address the analysis of the current nocturnal landscape image, carried out through both qualitative and quantitative analysis. In the paper results obtained from the application of the method to a case study are presented
A Novel Approach for the Assessment of the Nocturnal Image of the Cultural Landscape
Get PDFPolicies aimed at urban and territorial development stressed the importance of landscape as a significant resource for sustainable and economic development. In this perspective, research on landscape visual values and people preferences can support the enhancement of the global values of territories. Currently, the theoretical framework and approaches are mainly limited to the day images of sites, while nighttime landscape is not usually considered. In this study, we defined a methodological approach to address the analysis of the nocturnal image of cultural landscape contexts, in order to define indications and support the inclusion of visual values in the process of public lighting design. The approach was conceived for territorial contexts characterized by the presence of small urban settlements located in prominent positions and involved a subjective survey, an in-field measurement campaign, and statistical analysis to identify significant correlations between subjective judgments and quantitative parameters. The effectiveness of the approach was assessed through the application to a case study. The study allowed identifying subjective factors (overall impact, architecture and historicity, correspondence, alteration) and objective parameters (ratios of regions’ area, luminance values, and luminance contrasts) which describe the nightscape of cultural landscape. Results demonstrated the presence of significant correlation between subjective factors and objective parameters. The application of the method could provide designers and planners indications useful for the design of outdoor lighting system, in order to include perceptual aspects in a holistic design approach, which promotes environmental, energy, economic, and cultural sustainability
Un progetto di luce tra conoscenza e valorizzazione: il quartiere EUR di Roma
No full textThe enhancement of historical contexts is nowadays a prominent theme in the cultural and architectural landscape. Besides the requalification of spaces, it is also relevant the nighttime image of the city. The light selects, amplifies, defines hierarchies and an artificial lighting project can fit into a wide sense of enhancement, becoming a tool for designing the night appearance of the urban landscape. The theme has been investigated through the analysis of a case study: the EUR district in Rome. By following a structured path of interdisciplinary knowledge, that involved the study of the historical stages of evolution of the urban fabric, was drawn up a lighting project. The neighborhood has many critical issues, summarized in the insuficent enhancement of the site. In this perspective, the project proposal arises as a solution that can bind together the disjointed fragments that now make up the area, enhancing it, and recreating a complex urban system, livable and enjoyable by a larger type of users
Comunicazione e valorizzazione delle architetture vegetali: il progetto della luce nei giardini storici
Get PDF"1981/2021 Giardini storici. Esperienze, ricerca, prospettive, a 40 anni dalle Carte di Firenze". Considering historic gardens as outdoor museums, it becomes necessary a technological adaptation in order to open them to a wider public in full safety conditions during night time, and preserving their frail substance and cultural message. The lighting design can turn the satisfaction of specific functional requirements into an innovative tool for enhancing a garden and communicate its own history, but only if the design process is wisely managed and aware of the place identity. Through the presentation of a project developed for the garden of Palazzo La Marmora in Biella, the contribution intends to illustrate the narrative and evocative potential of light. Despite its small size, this historic garden expresses the transition from a baroque regular design to more organic forms of the nineteenth-century landscape. The search for the nature of the place has shaped the design intentions, highlighting how artificial light can be an adaptable and effective tool to enhance the mutability of the garden
AN EXPLORATORY STUDY TO ASSESS OUTDOOR LIGHTING IN URBAN CONTEXTS CONSIDERING IMPLICATIONS ON HUMAN HEALTH AND WELLBEING
No full textOutdoor lighting is an essential service and offers many benefits to users; however, excessive exposure to ALAN may have adverse effects on human health and well-being. Studies on light pollution are mainly based on the evaluation of the phenomenon on the horizontal plane, through nighttime satellite imagery. However, the assessment of the quantity and the spectrum of light on vertical planes is more relevant when the influence on human health is considered. In this paper, a methodological approach for the assessment of ALAN in a city context is presented. The study involved the assessment of light pollution through in-field measurements (photometric and spectral measurement campaign), to evaluate the phenomena considering the impact of light on buildings and on the human visual system. Some preliminary results and data elaborations referred to the application of the research methodology to a case study are presente
Preliminary results on integrative lighting in classrooms: simulations and field measurements
No full textThe paper presents results from a study on integrative lighting for real middle school classrooms located in a school building in Turin, Italy, considering the contribution of both daylighting and electric lighting. The research addressed two main objectives: (i) to verify if the circadian values
(melanopic equivalent daylight illuminance m-EDI) calculated or measured in the classrooms could meet the reference values reported in recent literature, for instance in the WELL protocol; ii) to assess the influence on integrative lighting (photopic and melanopic illuminances) played by the electric lighting and daylighting and, for this last condition, analyzing the impact of different room orientation and sky conditions
Renovation of Public Lighting Systems in Cultural Landscapes: Lighting and Energy Performance and Their Impact on Nightscapes
Get PDFThe technological innovation in the field of lighting and the need to reduce energy consumption connected to public lighting are leading many municipalities to undertake the renewal of public lighting systems, by replacing the existing luminaires with LED technologies. This renovation process is usually aimed at increasing energy efficiency and reducing maintenance costs, whist improving the lighting performance. To achieve these results, the new luminaires are often characterised by a luminous flux distribution much more downward oriented, which may remarkably influence and alter the perception of the night image of the sites. In this study the implications of the renovation of public lighting systems in terms of lighting and energy performance as well as the effects relating to the alteration of the night image, in historical contexts characterized by significant landscape value, are analysed. Results, along with demonstrating the positive effect that more sustainable and energy efficient lighting systems may have on the lighting performance and energy consumptions of public lighting systems, evidences the impact they may have on the alteration of the nocturnal image
