A stochastic thermo-economic analysis of solar domestic hot-water systems in compliance with building energy code requirements: The case of Spain

Spanish residential buildings typically cover the required domestic hot-water renewable fraction regulated by building codes using solar thermal systems, typically through solutions based on flat-plate collectors and water storage tanks. For medium or large buildings (with high domestic hot-water de...
