Summary: Urban settings and climate change both impact on energy use and thermal comfort inside buildings. This paper presents a study on the changes in energy demand and thermal comfort due to the effects of climate change and urban heat island intensity in two European locations. The results show that both hot and temperate climates will experience an increase in cooling demand and total energy demand due to future climate change and urban effects. In addition, the study highlights the importance of considering microclimatic conditions in naturally ventilated buildings, as variations in wind can significantly impact ventilation rates and internal operative temperatures.

Summary: The performance and durability of building components depend not only on the quality of construction materials used, but also on the ground condition beneath the foundation. Certain soil types, such as expansive soils, sulfur-rich soils, and hydrocarbon-contaminated soils, are vulnerable and can affect engineering performance. To improve the performance of these soils, various geotechnical techniques and additives are available, with geopolymer being introduced as a new method for soil stabilization. This review examines the use of geopolymer and other additives to strengthen poorly stabilized soil and improve engineering performance with minimal environmental impacts.

Summary: Vermicomposting is an energy-efficient and infrastructure-friendly method that can restore soil nutrition and carbon. Banana cultivation generates a large amount of waste each season, with 30 tonnes of waste per acre. Vermicomposting can recover valuable components such as lignin, cellulose, pectin, and hemicellulose from banana leaves. By combining biochar with banana leaf waste and cow dung, enriched vermicompost with higher nutrient levels can be produced.
