Question: How can I improve the energy efficiency of my facility's ancillary systems?
Answer: Ancillary systems issues, which include problems with kitchen equipment, laundry equipment and pools can take several forms. An energy audit will typically identify energy inefficiencies in one or several of the following areas:
- Kitchen equipment is not used efficiently
- In-house laundry equipment is not used efficiently
- Swimming pool water temperature is too high
- Use of equipment associated with laundry and custodial services coincides with heavy electrical demand periods
The suggested operations and maintenance ("O&M") improvements and facility improvement measures ("FIM") will vary based on your facility's unique mix of inefficiencies, but what follows are some general guidelines.
Suggested Ancillary Systems O&Ms:
- Cook with lids in place on pots and kettles.
- Preheat ovens only for baked goods.
- Reduce temperature or turn off frying tables and coffee urns during off peak periods.
- Provide ovens and fryers with loads all of the time they are heated and on.
- Use dishwasher for full loads only.
- Shut down exhaust hood fans when not required.
- Use microwave ovens for small orders.
- Develop concise operating procedures for each piece of equipment.
- Iron only items which require it.
- Wash and dry full loads only.
- Consider rescheduling laundry work hours to avoid periods when building experiences its peak electrical load if electricity demand charges are significant.
- Consider cold water detergents.
- Reduce pool water temperatures to 80-84 degrees Fahreneheit if users can accept it.
- Indoor pool: turn off heater and circulating pumps during periods of non-use.
- Require that major electrical equipment be used in accordance with guidelines that avoid peak electrical demand periods.
Suggested Ancillary Systems FIMs:
- Install a demand control system to automatically monitor power demand and to shut off assigned secondary loads to lower demand peaks to pre-established level.
