AB Since the current contribution of solar thermal energy to the amount of energy consumed for domestic hot waterin buildings worldwide is very low (8.4 %, approximately), the potential of this renewable energy to meet thedemand for domestic hot water is quite significant. In this context, this paper presents a new façade-basedbuilding integrated photovoltaic-thermal system with phase change material which has been patented recently. Itis a modular device for installation on façades and roofs, enabling the production of domestic hot water andelectricity using solar energy. The main novelty of the system lies in the use of a photovoltaic glass sheet, whichimproves the building’s aesthetics and facilitates the architectural integration of this type of devices. Thus, aphotovoltaic glass is used for the production of electricity, a phase change material for heat storage and a waterphasechange material exchanger for the production of domestic hot water. The design and verification stages ofthe system were developed for a case study under typical usage conditions. Two dimensional numerical modelsof five different configurations (of the energy harvesting and storage module and two dimensional and threedimensional numerical models of the finned exchanger were carried out to simulate the charge and dischargeprocesses. The most suitable configuration of the system, characterised by a 12 mm vacuum gap and a lowemissivity of the absorber, was able to meet the requirements in terms of water flow rate and supply temperature(45 ◦C) for a shower time of 5 min.
