The effective thermal management of Lithium-Ion Batteries (LIBs) is essential for ensuring safety, extending cycle life, and maintaining performance in electric vehicle applications. Among various approaches, passive battery thermal management systems (PBTMS) using phase change materials (PCMs) provide a cost-effective and reliable solution compared to conventional active cooling. This study proposes a novel conical cylindrical chamber (CCC) design for PCM encapsulation and evaluates its impact on LIB temperature regulation. A three-dimensional Computational fluid dynamics (CFD) model based on the enthalpy-porosity method was developed to simulate coupled heat transfer and phase change phenomena under dynamic discharge conditions. The effects of chamber geometry (top and bottom radii), different PCM types, and discharge rates (1-3 C) were systematically investigated. Results show that chamber configuration strongly influences PCM melting efficiency and battery thermal response. For example, the optimized CCC geometry reduced peak battery temperature by nearly 30 °C compared to less efficient designs, while poorly configured chambers left up to 38% of the PCM unmelted at end of discharge. The study demonstrates that balancing CCC surface area and PCM volume is critical for maximizing heat absorption, minimizing thermal gradients, and enhancing passive cooling. These findings provide design guidelines for next-generation passive thermal management systems in LIB applications.

The building industry is in constant change and the United Arab Emirates (UAE) is a leader in innovative solutions for green buildings. The standards used in achieving sustainable buildings, such as LEED, Estidama, have contributed to building structures that reduce energy consumption. More than 40% of the total energy is consumed by residential and commercial buildings as electricity. The strategies applied in a building in order to have low energy consumption vary depending on the region and climate. In the UAE, a country with a hot arid climate, these strategies have relevant importance. The aim of this study is to design an innovative parametric/dynamic façade in a new building, to be built on the United Arab Emirates University Campus, AL Ain, Abu Dhabi, UAE. The new structure is an additional library building (with additional functions to the current building). The design shall be based on the region’s architectural heritage. The modelling and simulation tools used are Rhino and plug-ins like Grasshopper. Furthermore, an optimization process of the parametric/dynamic façade is conducted. Based on the energy simulation results, the application of the innovative parametric/dynamic façade brings a reduction of 25% in the energy consumption of the building. In addition, the daylight improvement by the application of this façade is 44%. This research brings innovation in terms of the advanced tools used in calculating several parameters for the advanced façade and the process from concept to modeling and simulation. These findings are promising for regional industry due to the advanced tools and methods used. Moreover, it shall help the local authorities such as Abu Dhabi Municipality achieve the sustainability goals 2030.

This study explores the role of green building technologies in the development of a sustainable future by evaluating the techno‐economic benefits of phase change materials (PCMs) in building walls. The purpose of this research is to investigate how PCMs can be incorporated into bricks to reduce the use of electricity for cooling the building and temperature fluctuations caused by varying indoor temperatures ( T _i = 18, 20, 22, and 24°C) and outdoor temperatures ( T _o = 25, 28, 31, and 34°C). An analysis of the thermal and economic behavior of three aluminum cylindrical capsules containing PCM embedded within brick structures is presented using computational fluid dynamics (CFDs) simulations conducted over a period of 12 h in order to determine the interaction between the brick, the PCM capsules, and the buoyant forces. Results indicate that PCM capsules perform optimally within specific temperature ranges, achieving their peak efficacy between 20 and 24°C, while 25–31°C are ideal T _o values. It is estimated that adoption of PCM‐integrated bricks can save you between $414.7k and $444.3k over the course of 30 years. The internal rate of return (IRR) of this system averages 1.583–1.70, which is significantly higher than the discount rate of 0.02, thus highlighting its attractiveness as an investment.

Due to the scarcity of water and the harsh desert climate of the United Arab Emirates (UAE), water and energy are two of the main challenges for the design of sustainable buildings in the UAE. Relevant literature calls for the consideration of building systems and materials at the design stage to achieve high-performing buildings and to save on the operational costs of the building. The aim of this research was to design a high-performance building that meets the environmental sustainability requirements for water and energy, in the city of Dubai to reflect the technological advancements of the UAE Mars mission. This has been achieved through following an integrated design process, which was mainly focused on the evaluation and specification of the building engineering systems based on performance, besides the goal of achieving visually appealing building with advanced structural design. The performance verification of the final building design, which considered engineering systems design from conception and through the design and detailed design stages, revealed a 15% reduction in water consumption and a 60% reduction in energy consumption. This provides a valuable contribution to architectural engineering practice, by demonstrating a case study for enhancing energy and water efficiency via building design, which consequently contributes to the environmental sustainability of the built environment.
