It is vital for all hospital systems to use as little energy as possible without compromising performance. Remember, the staff and patients within the hospital have to live with the system for 30 years or more. Therefore it is important not only to look at the initial cost but the life cycle cost of the system. On the average, the capital cost of a system is only 20% of the total life cycle cost.

A great deal of energy can be recovered from extract air which can be used to reduce energy costs. Typically, in new hospitals, 40-50% is recovered. If we can recover 70% of the energy then the heating load required from the building heating system reduces to around 20%. More interesting is the potential to recover cooling from the extract air. With higher efficiencies, the amount of cooling energy recovered is significant and as chillers are one of the major users of energy within a hospital, any reduction in the chiller load has a dramatic positive effect on savings.
