“…For this, the software has been developed into a new leakage network model and generates accurate calculations in the fields of water and energy (Pardo & Riquelme, 2019). UAleaks can also be used for sizing small solar water heating systems by allowing the sizing of natural and forced circulation systems and modifying the input parameters at any time, making it possible to simulate different situations and identify optimal technical and financial solutions (Camargo Nogueira et al, 2016). Some GIS software is free and open-source.…”

Several Arab countries face numerous environmental problems in addition to climate change, desertification, and water crisis. Multiple issues related to water and energy need to be resolved. In this paper, we examine the most important topics to be studied, and the research conducted to elucidate the importance of the water problem in the Arab region, including the gap between increased demand and a lack of resources. Water problems include leakage, pollution, and depletion of water resources. We also focus on climate change and the role of young people, software, educational institutions, and training centers in achieving water security and sustainable development objectives. The paper also investigates the idea of water harvesting, the relationship between water, food security, and energy, the role of stakeholders, and good governance in solving the water crisis by understanding the problems and framing research within a multi-year work program with financial, legislative, and scientific support. Providing incentives and the necessary research structure to coordinate all sectors and organizations concerned with water is also essential.

“…f -chart was developed using a large number of transient simulations to develop correlations among dimensionless parameters that could be easily calculated from available input data [32]. The f -chart method is still used nowadays as a base for sizing [33], energy performance evaluations [34] and standards [35], but it assumes that the system is correctly sized and operated.…”

Thermal solar systems are interesting solutions to reduce CO 2 emissions and gradually promote the use of renewable sources. However, sizing such systems and analysing their behavior are still challenging issues, especially for the trade-off between useful solar energy maximization and stagnation risk minimization. The new EPB (Energy Performance of Buildings) standard EN 15316-4-3:2017 offers several methods to evaluate the performance of a forced circulation solar system. One of them is a dynamic hourly method that must be used together with EN 15316-5:2017 for the simulation of the stratified storage tank connected with the solar loop. In this work, such dynamic hourly method is extended to provide more realistic predictions. In particular, modeling of the pump operation due to solar fluid temperature exceeding a set threshold, or due to low temperature differential between solar field and storage tank, is introduced as an on–off control. The implemented code is applied to a case study of solar system for the preparation of domestic hot water and the impact of different design parameters is evaluated. The model predicts a higher risk of overtemperature lock-out or stagnation when the solar field surface is increased, the storage volume is reduced and water consumption is set to zero to simulate summer vacation periods. Finally, a simple modulating control with a time step of a few seconds to a few minutes is introduced, quantitatively showing the resulting benefits in terms of useful solar energy increase, back-up operation savings and reduced auxiliary energy use.

In this study, utilizing a renewable energy system was proposed to eliminate conventional sources used for swimming pool heating applications. The proposed configuration mainly consisted of a private swimming pool, ground source heat pump, buried energy storage tank, and solar collectors. The solution of transient heat transfer around the storage tank and energy equations for the other configurations are integrated with MATLAB software to develop an analytical model. Analytical model was used to detect the most suitable swimming pool heating system parameters offering a reasonable heating performance yearround as well as to evaluate different performance parameters of the system.The typical meteorological data of Gaziantep city was embedded into the developed computer program to find reasonable water temperatures, solar collector area, suitable tank volume, and time to arrive at periodic conditions. The results showed that when the area of the pool was simulated at 50 m 2 , the underground thermal energy storage tank volume equated to 300 m 3 , while the collector area became 100 m 2 , and the periodic operation was equal to 6 years. Finally, the results showed that the swimming pool heating system derived the majority of its total energy requirement from solar energy (being 86.18%), in addition to utilizing the heat pump (being 13.82%), during the first year of operation.
