Yearly operation of a building-integrated microcogeneration system in south Italy: energy and economic analyses

This article investigates the yearly operation of a building-integrated micro-cogeneration system through transient simulations; both energy and economic performance of the proposed system are analyzed and compared with those of a conventional system based on separate energy production in order to assess the potential savings. The energy comparison is carried out in terms of primary energy with respect to the specific Italian electricity mix; the economic analysis is performed by considering both the operating and capital costs, with the energy unit costs as well as the incentives for supporting the cogeneration technology evaluated according to the Italian scenario.
