Hospitals are one of the largest consumers of electricity in the commercial consumers category. They have the highest energy use, per unit of floor space. The large array of equipment and various utilities in a hospital mean that energy bills account for a lion’s share of the hospitals outgoings. However with active measures taken, the energy consumption of hospitals can be drastically reduced.
One of the major consumers of electricity within the hospital environment is the ventilation system. Hospitals often require 100% ventilation of fresh air to reduce the risk of microbial contamination. The HVAC system accounts for 45% of the total energy used in hospitals. Lighting is another area of energy consumption accounting for at least 25%. Other operations such Laundering, sterilization, and cooking account for another 30% of energy expenditure.
