This Application Note describes the use of energy and the potential energy savings in the hospital sector, on the basis of theory and practical case studies. Hospitals represent some 6% of total energy consumption in the utility buildings sector, which includes offices, shops, hotels, restaurants, educational establishments and care institutions.
The great majority of the energy used within a hospital is purchased from outside in the form of natural gas and electricity. A small proportion is bought in as diesel oil. All this energy is converted by a number of systems into the most important internal flows of energy, namely heat, cold, electricity and compressed air. These energy flows are analysed in this application guide.
