“…In this regard, References [12,13] show simulation approaches to the representation of malfunctions/faults of marine engines and auxiliary systems for the thermal energy recovering from the exhaust gas of the engines. In the same research field, References [14][15][16] propose different simulation techniques (e.g., neural networks) for the marine engine diagnostics, while [17][18][19] show further examples of dynamic simulation approaches to the design of the ship energy systems Focusing on marine propulsion systems, a good simulator is made up of several numerical sub-models that represent the main elements involved in ship propulsion. Surely, the main mover model can strongly characterize the complexity of the simulator as it can be faced with different approaches.…”

The article deals with a simulation approach to the representation of the ship motions in waves, interacting with the propulsion system behavior (diesel engine and propeller). The final goal is the development of a simulator, as complete as possible, that allows the analysis of the main engine thermodynamics in different sea conditions, also in the unfavorable event of dynamic instability of the hull, and the correct management of the other propulsion components. This latter aspect is particularly interesting in some of the last new energy solutions for decarbonization of ships, concerning, for example, auxiliary electric motors, powered by batteries, to support the traditional diesel-mechanical propulsion (especially in heavy weather conditions). From this point of view, a proper analysis of the engine dynamic performance, affected by particular sea states, is fundamental for a smart management and control of shaft generators/auxiliary electric motors, batteries, etc. To this end, the work presents and highlights the main features of a ship simulator, suitable for the study of the new propulsion solutions that are emerging in maritime transport. Some representative results will point out the complex non-linear behavior of the propulsion plant in waves. Moreover, a parametric roll scenario will be investigated, in order to highlight the capability of the conceived simulator in modeling the effects of the dynamic instability of the hull on the propulsion plant.

The building sector is one of the main energy-consuming sectors in Morocco. In fact, it accounts for 33% of the final consumption of energy and records a high increase in the annual consumption of energy caused by further planned large-scale projects. Indeed, the energy consumption of the building sector is experiencing a significant acceleration justified by the rapid need for the development of housing stock, wich is estimated at an average increase of 1,5% per year; furthermore, tant is an estimated increase of about 6,4%. In this sense, building constitutes an important potential source for rationalizing both energy consumption and energy savings through the adoption of energy efficiency measures. Energy consumption control efforts in the residential building sector involve socioeconomic, technological, and environmental concerns that require sophisticated research. Indeed, different types of quantitative models have been developed and examined so as to find a solution for the optimizing energy consumption. In this work, we have highlighted the importance of using solar heaters to reduce energy demand in terms of the use of domestic hot water. To do this, we have defined the needs and characteristics of a solar installation of a residential building located in Casablanca through a calculating tool "SOLO 2000" in addition to the use of multiple linear regression analysis to deduct the impact of irradiation and solar contributions on the energy demand of the solar installation.

“…Among all the highly energy-intensive sectors, such as communities [ 1 ], transport [ 2 ], and buildings [ [3] , [52] ], the latter is one of the most impactful, being responsible for high primary energy consumption and CO 2 emission [ [4] , [51] ]. In this context, the relevance of the ventilation system in buildings, and in general in enclosed spaces, is well understood and researched in the scientific community since it aids in preventing the spread of common pollutants, viruses, bio effluents, etc.…”
