Summary: Spanish residential buildings usually use solar thermal systems to meet building code requirements. The energy savings of these systems are significant for medium or large buildings but may not be economically feasible for small buildings. A simulation tool was used to estimate the energy savings and conduct economic feasibility assessments. Results showed that solar domestic hot-water systems are not economically feasible for small buildings with less than 5 apartments, but have a wide probability range (70-90%) of being economically feasible for buildings with more than 48 apartments.

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.
