The objective of this study is to provide a good "benchmark" case in juice fruit production plants for comparing their performance in terms of energy consumption and final product "yield". In particular, the industrial step-by-step processes performed for the production of natural fresh orange juice, fruit juices and purees will be dissected, also referring to the operations. By exploiting the Value Stream Mapping (VSM) methodology, we report general energy consumptions due to the main production processes and highlight the most energy-intensive ones, in order to provide a base for the selection of useful and reasonable key performance indicators. Furthermore, we include some sectorial KPIs that have been extracted from the literature.

The agriculture and agro-industry system, in the overall definition of agricultural production, processing industry, distribution and services, is characterized by a strong demand for innovation to satisfy the continuous and changing needs of consumers. This situation, on the one hand, is determined by the needs of companies to respond effectively to market globalization, on the other hand, however, it has strongly increased energy consumption and the environmental impacts of the sector. This work examines the energy consumption of the agri-food supply chain and illustrates the most significant technologies and production processes for sustainable energy and environmental modernization.

Tourism is a sector that accounts for about 10% of European GDP and represents a powerful engine of local development and employment in the European Territory. Europe is the main tourist destination in the world, with 671 million international arrivals in 2017 and Italy is the fourth country in Europe for accommodation facilities. To guarantee "sustainable" accommodation facilities, it is necessary to invest in innovation and technologies that enable energy savings. To support investments in terms of improving the energy efficiency of accommodation facilities, the sector can use the incentive and tax relief system, such as: thermal account, restructuring bonus, eco bonus for energy efficiency, the Tax credit for redevelopment.

The environmental impacts deriving from pollution due to the high use of cooling and heating systems in buildings have made it necessary to study alternative methods of designing or upgrading existing buildings. In this work the concepts of bioclimatic architecture are discussed and possible technological solutions for energy saving in the construction sector are presented. The solutions proposed concern orientation, the shape of the building and the internal volumetric arrangement. Attention is paid to internal comfort and the problem of convective motions related to the cooling of homes. Other solutions referring to the use of bioclimatic diagrams to determine the maximum and minimum temperatures to be considered for bioclimatic design are also proposed.
