The geothermal potential of underground buildings in hot climates: Case of Southern Algeria
Underground buildings are one of the most effective old and modern techniques, at the same time to meet the trade-off between thermal comfort and low energy consumption in hot and arid climates, through the soil thermal properties, which can be applied as a heat capacitor for moderating indoor tempe...
