Electrical Energy Consumptions in Hospitals - The Case of Lifts

Energy Consumption, Hospitals, Lifts


Each hospital building is unique and most do not follow a typical prototypical form or floor plan. Any hospital is likely to differ significantly from another based mainly on the services offered. The architectural form of a healthcare building i.e. whether the building has a small footprint and is tall, or has a large footprint and is low is important. In the tall form case, the lifts are used as a primary circulation element and their proper operation is vital, particularly when dealing with operating theatre emergencies. This work is proposing a calculation method of electricity consumption of lifts in hospitals based on the kind of lift, the number of lifts, their load factor, the simultaneous factor, the total installed motor power of lifts per air-conditioned floor surface unit and their average total operation time. At the end an example is given based on data received from “typical” new Greek hospitals.
