Hospitals require simultaneously different forms of energy such as thermal energy, steam, electricity and cooling. On the other hand, they suffer from the heat losses released by the incinerator, the medical air group and especially by boilers. The purpose of this paper is to illustrate some energetic problematics in Moroccan hospitals, and establish a novel configuration of a polygeneration system that will remedy to these barriers with the better energy efficiency and with less emission. This will be performed by integrating solar energy and recovering the energy emitted by both the incineration and the boiler for a Combined Cooling, Heating and Power (CCHP) plant. Indeed, Moroccan hospitals have the characteristic that they will largely expect benefit from solar energy to supply the equipment of a polygeneration system. This will be the way to provide efficiently electricity, heat, cooling, hot water and steam since these forms of energy are all required throughout the year in public hospitals, in order to provide comfort to patients and caregivers.
