Summary: One of the new strategies in energy efficient building is integrating phase change materials (PCM) into the building structure. This study investigates the thermal behavior of a building wall with different types and thicknesses of PCM in the hot summer of Aswan, Egypt. ANSYS 2020 R1 is used to design and simulate a 2D thermal model, and the effects of PCM types, thicknesses, and locations on the inner wall temperature are analyzed. The results show that using PCM in the wall structure reduces indoor heat flux and brings the internal wall temperature closer to desired levels, with RT-35HC performing the best and the optimal PCM location being 1.5 cm from the inside and outside of the wall. The use of 1.5 cm RT35HC-PCM results in a 66% reduction in overall energy gain over the summer.

Summary: Passive latent heat storage for building applications utilizes phase change materials (PCMs) to reduce energy consumption and provide thermal comfort. Integration of PCMs in building envelopes can reduce peak temperature and smooth thermal load, but challenges remain in studying long-term stability, moisture, mass transfer, and actual building use. The use of fatty acids and eutectic mixtures in shape-stabilized PCMs composites shows potential for improving efficiency of passive systems.

Summary: Zero energy buildings (ZEBs) have attracted significant attention in the US, with the potential to achieve more cost-effective energy savings through new materials and systems that regulate building enclosure heat losses and gains. The study on thermo-optically responsive solid-solid phase change material (SS-PCM) coatings demonstrates their ability to reduce heat exchange in building enclosures and highlights the rooftop as the optimal location for installation. The findings also suggest that SS-PCM systems offer more thermal benefits and energy savings in warm climates compared to cold climates, presenting a promising solution for existing passive solar facades.

Summary: This study examines the impact of land cover, vegetation health, climatic forcings, elevation heat loads, and terrain characteristics on land surface temperature distribution over West Africa. The random forest model performs the best in downscaling predictands. The southern regions consistently exhibit healthy vegetation, while areas with unhealthy vegetation coincide with hot land surface temperature clusters. Positive Normalized Difference Vegetation Index trends in the Sahel highlight rainfall recovery and subsequent greening. Southwest winds cause the upwelling of cold waters, resulting in low land surface temperatures in southern West Africa. Considering LVCET factors is crucial for prioritizing greening initiatives and urban planning.
