“…Consequently, multilevel material cycles with a complete renewability of the exergy cannot be designed, but exergy loss can be limited (entropy production can be minimized). Gulotta et al [43] propose extensions of the Cumulative Exergy Demand (CExD), a concept introduced for tracking destroyed exergy through LCA comparisons of technology systems. CExD is the sum of exergy of all resources (including fuels and chemical potential) required to provide a process or product.…”

A sound theoretical ground is required for sustainability related concepts reconciliation and operationalization. The current study investigates the opportunities to conceive a homogenous sustainability model derived from theoretical ecology, using as a prototype the “organization” concept from the Chemical Organizations Theory (COT). A sustainability problematization and a literature examination try to capture and link some useful perspectives and sustainability connected concepts. Some of the most influential methods and tools are reviewed, in particular among those relating to the triple bottom line framework and to the ecological footprint family, together with concepts close to the core sustainability definition, like resilience and circularity. Theoretical ecology provides candidate goal functions based on self-organization gradients, such as fitness functions and thermodynamic orientors. The COT formalism provides a higher abstraction level and the algorithms for patterns identification in a reactions network. The sustainability problematization reveals the motifs of a possible model of “total ecosystem”, which subordinates the anthropic cultural (social–economic) system to the thermodynamic, chemical, biological, and cultural determinisms regulating biological and cultural species of an ecological network.

In the present times, the use of air cooled condenser (ACC) has become generalized where the installation of power plants is required and access to condensation water is difficult. At present it is known that performing the thermal evaluation of an ACC is a complex task, since the existing methods do not consider all the elements that directly influence the performance of the ACC. A very widespread method is that attributed to Kröger, however its use does not provide adequate results for high values of environmental temperature, which is a limitation to be applied in tropical countries like Cuba. This document provides an analysis method that includes the effect of environmental variables and that allows reasonable results to be obtained for high values of ambient temperature. The new proposal follows the logical sequence of the Kröger method, but considering a new procedure for the determination of the mean heat transfer coefficients and pressure drops, required for the thermal evaluation of ACC.

“…Quantitative indicators should be used to assess the impacts of integrated urban regeneration and soft mobility policies (Mutani, 2018). Among others, it can be assumed that the reduction of energy consumption is a valid and effective indicator of the impact on the environment and, consequently, the effects on the levels of environmental pollution and on the quality of social life could be derived (Gulotta et al, 2018). In order to estimate the energy consumption of vehicular traffic, we now have general modelling tools (simulation models of transport networks and the interaction between mobility demand and supply) as well as specific models such as those designed to determine consumption energy in relation to attributes of the transport system such as vehicle flows, distances travelled by vehicles, infrastructure service levels (congestion, run-off speed).…”

The new generation of plans (Urban development plans, Sustainable Urban Transport Plans) in Italy, as well as in Europe and in other international contexts, tends to combine different actions such as urban regeneration, enhancement of areas of particular value, containing of negative traffic impacts, also through innovative technologies and measures, in particular in the ITS field (Intelligent Transportation Systems), soft mobility (pedestrian and cycle mobility, zero emission vehicles, shared mobility, green and clean public transport, etc.). The paper proposes an integrated approach to urban regeneration policy and soft mobility planning, aimed at significant transport energy-saving and environmental sustainability. The attention is focused on Transport models able to provide quantitative impact indicators of these integrated policies in terms of less energy consumption for the urban community. A specific application is proposed, for demonstration purposes, with reference to an ordinary day and a specific area of the Reggio Calabria city center, subject of a specific environmental upgrading and associated reorganization of the transport supply in soft mobility terms. RÉSUMÉ. La nouvelle gé né ration de plans (plans de dé veloppement urbain, plans de transport urbain durable) en Italie, ainsi qu'en Europe et dans d'autres contextes internationaux, tend à combiner diffé rentes actions telles que la ré gé né ration urbaine, la mise en valeur de zones pré sentant une valeur particuliè re, contenant des impacts né gatifs sur le trafic, é galement par le biais de technologies et de mesures innovantes, en particulier dans le domaine des STI (systè mes de transport intelligents), mobilité douce (mobilité des pié tons et des cyclistes, vé hicules zé ro é mission, mobilité partagé e, transports publics é cologiques et propres, etc.).Le document propose une approche inté gré e de la politique de ré gé né ration urbaine et de la planification de la mobilité douce, visant à é conomiser l'é nergie de transport important et la durabilité environnementale. L'attention est concentré e sur les modè les de transport capables de fournir des indicateurs d'impact quantitatifs de ces politiques inté gré es en termes de moindre consommation d'é nergie pour la communauté urbaine.
