Recently, the problem of indoor air pollution by microbes has attracted attention in hospital and other medical facilities. For example, control measures against such as methicillin resistant staphylococcus aureus and legionnaire pneumophila has been needed. The other hands, reducing of carbon dioxide emission has been a matter of great urgency on environmental problem. In buildings field, saving energy of using or operating building equipment important problem. But, air conditioning equipment occupies the large ratio of energy use for arranging indoor air environment satisfying various demands as medical facilities, for example, cleanliness air for patient, prevention from infection.The object of this study is that establishing of methodology on equipment design and schemes of its operating in hospitals ,considering preservation of suitable environment for medical facility and energy saving. So, we have made a database on hospital facility design in Hokkaido, and analyzed it for the purpose of understanding the present about hospital equipment systems and its operations.
