Summary: This study proposes a multi-objective optimization framework for designing photovoltaic-integrated shading devices (PVSDs) that maximize PV potential, minimize PV area, and enable proper sunshade duration. GIS-based spatiotemporal analysis and optimization methods were applied to determine the optimal PVSD widths in different scenarios. The results show that optimized 0.7-m-wide PVSDs in the real-time rotating scenario can generate 0.861 GWh of electricity annually, with competitive power generation efficiency and sunshade duration. Flexible installation scenarios are suggested to account for shading from other upper PVSDs and surrounding buildings.

Summary: This paper introduces a circuit simulation method for PV modules with various pattern styles, and validates its robustness through custom PV mini-modules that allow for I-V curve measurements and analysis. The electrical and thermal characteristics of dot-matrix patterned (DMP) modules are analyzed in detail, showing that pattern shading decreases module power but slightly increases fill factor and relative efficiency. The power reduction of dot-matrix patterned modules is less than continuous patterned modules, and inhomogeneous pattern distribution causes additional power loss and local temperature rise.

Summary: Qatar, a peninsular country, has hot and humid weather, and 88% of its population consists of immigrants. This makes the country vulnerable to the introduction and spread of vector-borne diseases, partly due to the presence of native arthropod vectors. The changing climatic conditions are expected to make Qatar's weather even warmer. Factors like humidity and temperature play a role in the breeding and distribution of different mosquito species in the region. Without proper precautions, high rates of specific mosquito species can lead to the transmission of various vector-borne diseases. This study analyzes the environmental impact on the occurrence of mosquito species in Qatar and proposes the use of a Naive Bayes model to predict favorable environmental conditions for specific mosquito species. The findings can help in planning and implementing surveillance systems and preventive measures to control the spread of mosquitoes in Qatar.

Summary: Buildings are major contributors to climate change in hot and dry climates, and climate change is expected to increase cooling demands. This study investigates the impact of climate change on cooling demands in different building types in Qatar and evaluates related environmental impacts. The study found that the cooling demand could increase by 13-53% and 19-67% in 2071 and 2100, respectively, and buildings with higher thermal insulation and lower window-to-wall ratio are less affected. Replacing natural gas with solar power can reduce cooling energy-associated CO2 emissions by 92%.

Summary: The serious threat of climate change has prompted GCC countries to aggressively seek clean energy sources. Recently, these countries have announced carbon emission targets, with some aiming for net-zero emissions by 2050 or 2060. Governments and energy companies around the world are betting on hydrogen to lower emissions. However, there are obstacles to the adoption of a green hydrogen economy in Gulf countries, including high production costs, infrastructure and transportation issues, regulation, and demand. This study analyzes the obstacles and future prospects of hydrogen economy in the GCC region using SWOT analysis, concluding that while GCC countries have the potential to lead in hydrogen, they need to take risks to compete globally, and the growth of the hydrogen economy depends on external factors beyond their control.
