Building-integrated trigeneration system: Energy, environmental and economic dynamic performance assessment for Italian residential applications

The primary energy consumption, the equivalent carbon dioxide emissions as well as the operating costs of the proposed system were evaluated based on the simulation results according to the Italian scenario and compared with those associated to a conventional system composed of a natural gas-fired boiler coupled with the same air-cooled water electric chiller fed by the electric grid. The performed analyses allowed to assess the energy, environmental and economic suitability of the proposed scheme as well as its potential benefits in comparison to the reference plant based on separate energy production.
