A relatively easy way to achieve energy efficiency is through load reduction – in other words, reducing or eliminating the run times of various types of equipment.

Load reduction may be achieved simply by turning equipment off, using timers, or using control systems.

Turn it off 

  • Evaluate your facility and ask the question, “Does this really need to be
    operating right now?” If it is determined that certain equipment doesn’t
    need to operate at that time, turn it off.

Timers 

  • Use timers to efficiently manage the operating hours of electrical
    equipment.
  • Program the desired operating hours and let the timer do the rest. Some
    timers automatically adjust for daylight savings, while others will need to be
    seasonally adjusted.

Controls

Controls vary from simple to complex.

  • Occupancy sensors are an example of simple controls. These devices are
    typically used in conjunction with lighting and help manage the operation
    of room lighting during normal business hours.
  • Daylight sensors, or photocells, are another example of a simple control and
    are an easy way to manage the operation of exterior lighting. These sensors
    need to be periodically cleaned, as a dirty sensor can cause outdoor lighting
    to operate during daylight hours.
  • Complex control systems include HVAC controls where there are multiple
    temperature and humidity sensors throughout the facility that communicate
    data to a central controller that adjusts the system operation accordingly.
