Use of Non-conventional Energy Devices in Hospitals
Non conventional resources are non traditional, these are not in routine use at present, these resources require some costly method to be converted into mechanical energy, these are non- depletable or may be available in vast quantities.
Example: Solar, Wind, Tidal geothermal and biogas are non conventional energy resources. Rising costs and depleting resources have prompted hospitals to adopt energy management systems.
Uninterrupted power supply is the foremost need in hospitals. “Energy is becoming a larger proportion of operating cost. In a 600-bed hospital, approximately 55 per cent of energy is consumed by Heat Ventilation and Air Conditioning (HVAC), 10 per cent by lighting, 9 per cent by medical equipment and the rest is used for elevators, laundry, kitchen, autoclave, etc.
Bed occupancy, continuous additions of hi-tech equipment, expansion of hospital, number of procedures, investigations, surgical intenentions and length of patient stay are some factors that determine the energy consumption in a hospital
Energy management is carried out in three steps.
• Calculating the energy expenditure.
• Identifying the areas of concern.
• Executing the changes.
