Summary: This study analyzed the use of UGCs in hot regions, showing that by enhancing external walls aboveground to ensure natural ventilation and daylight, temperatures can be decreased by 3 degrees C in summer, with evaporative cooling further cooling the indoor environment by nearly 12 degrees C. Heat transfer was found to be significantly affected by the external environment, with a doubling of heat transfer in underground constructions compared to aboveground. Small windows for ventilation in hot regions during summer led to high humidity levels.

Summary: A natural deep eutectic solvent-based polyacrylamide/poly(vinyl alcohol) hydrogel with nanoparticles (NPs/NADES@PAAm/PVA) has been developed for protecting fruits from excessive solar radiation and high temperature during transportation, retail, and storage. The hydrogel demonstrates excellent solar reflectance and emittance, as well as flexibility, mechanical strength, and swelling behavior. Experimental results show that the treated pear exhibits significant temperature decrease and similar quality attributes to the fresh one after sun exposure. Therefore, NPs/NADES@PAAm/PVA has promising prospects for fruit preservation under solar radiation.

Summary: Recent technological advancements in the HVAC industry have led to optimized occupant thermal comfort and system efficiency through better control of comfort parameters. This study focuses on automatically regulating thermal comfort parameters, such as temperature, airflow, and humidity, using an air handling unit equipped with fresh air control for air quality, a chiller unit for cooling and dehumidification, an ultrasonic mist humidification system, and an air volume control system for temperature control. These systems are controlled based on feedback from various sensors in the target space to meet the ASHRAE Standard 55. Experimental results in Dubai showed that the adaptive-controlled system achieved a maximum coefficient of performance (COP) of 8.60, dehumidification effectiveness (DE) of 0.96, humidification effectiveness (HE) of 36%, predicted mean vote (PMV) of -0.62, and a bypass factor of 0.48 under outdoor conditions of 42 degrees Celsius and 50% relative humidity. The adaptive-controlled system was found to be 21.50% more efficient than a conventional system.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
