The proposed interventions plan primarily meets the hospital's energy needs Utilizes the potential for energy savings leading to the hospital's energy housekeeping and based on its new energy profile, interventions of a three-generation heat-cooling system are planned in the hospital's facilities with the maximum degree of efficiency The conversion of the existing BMS into BEMS is the main tool for the preparation of a hospital energy management plan in response to the requirements of Law 43422015 and the European Directive of 30 May 2018. The combination of an action plan that incorporates best practices and a tool that allows the energy planning to establish and mainly monitor indicators of the hospital's energy behavior ensures to the maximum extent possible that the operation of the hospital is completely controlled and therefore efficient. The draft law in question leads to the optimal efficiency of the system with the consequent maximum primary energy savings, the reduction of pollutants at national level and a very significant reduction in energy costs. The proposed interventions plan after its implementation will achieve primary energy savings of 517 compared to the current operating situation, a percentage that is too large for a hospital of its size, while the reduction in pollutant emissions that will occur as a result of the implementation of the energy upgrading plan is estimated at 142583tn CO2 per year.
