Abstract

Long-term energy storage has great potential to decrease the consumption in buildings, particularly through saving summer excesses to cover winter demands, thus equilibrating the system in both seasons. This chapter deals with hot water storage over 6 months period for an example storage facility in Sofia. Using exact building and weather data in a mathematical model, taking into account fundamental thermodynamical relations, we show amount of energy stored, impact of convection on the thermal losses and we make reference to the building requirements and possible improvements.
