Energy sufficiency of an administrative building based on real data from one year of operation

This article describes a method to optimize the utilization of a BIPV system with battery energy storage at an administrative office building in Jesenik, Czech Republic. Solar analysis is taking into account constraints from the architecture and surrounding of the building in order to identify suitable surfaces and propose BIPV solutions. A validated PV model is used for the estimation of the annual energy output depending on the PV configuration (technology, capacity etc.). Based on real data from one year of operation, an emphasis is also be given on the optimal control strategy for the operation of the system with the aim to increase the self-sufficiency of the building. To this end, optimal solution is proposed indicating the optimal strategy in terms of increasing the sustainability of the building with the minimum required cost.
