• The energy cost to run a motor for two months can be greater than the initial purchase price. Modern motors, to the new mandatory motor efficiency standards IE2, are substantially more efficient, paying back their purchase price within a few months.
  • Users who employ an effective motor management policy which includes motors, Variable Speed Drives (VSDs), gearboxes and the driven machine can release further savings.
  • Variable Speed Drives (VSDs) optimise the voltage and frequency supply to the motor to match the speed to the actual load demand, reducing energy consumption significantly. Even relatively small reductions in speed can produce significant energy savings.
  • Choose light bulbs carefully. Compact fluorescent light bulbs (CFLs) use 75 percent less energy than standard incandescent bulbs and last 10 times longer. For example, a 20-watt fluorescent bulb is equal to a 60-watt incandescent bulb. They can also be used as porch lights
  • Install dimmer switches and three-way bulbs. They use less energy and let you enjoy a choice of lighting levels for different tasks
  • For outdoor use, consider high-pressure sodium bulbs, which are more efficient and last longer than their incandescent counterparts
  • When buying bulbs, check the lumens. The higher the lumens, the more light you’ll get
  • More light shines through when you keep dust off your lampshades, light fixtures and bulbs
  • Because light bounces off walls and ceilings, you’ll get more light for the money if you paint your walls light colors
  • Increase the power of reflection by putting lamps in corners where two walls reflect light into the room
  • Take advantage of free light from the sun by putting furniture near windows
  • Place security lights on a timer or photo-electric control so they’ll turn on and off automatically. Mercury vapor or high-pressure sodium lights are the best energy buys for outdoors
  • The three basic functions of a Building Energy Management System (BEMS) are improving plant control, monitoring energy usage and optimising plant operating times. You can achieve savings of anything up to 30% by installing and maintaining an effective BEMS.
  • Some of the easiest energy savings can be made through effectively managing BEMS time clock schedules, to ensure plant is not running overnight, at weekends or on bank holidays, unless required.
  • Monitoring your environment controls can also help, ensuring that heating and cooling systems are not working against each other.
  • Implementing intelligent lighting systems can save over 40% of energy used in lighting.
  • Light fittings can be individually controlled to turn them off or even dim the output as required. Used in conjunction with light level sensors and presence detection, controls can be optimised to take full advantage of daylight savings and maximum off periods.
  • Significant additional savings can be made due to reduced maintenance requirements – more easily scheduled with predictive failure analysis.
  • Once installed, lighting controls provide excellent flexibility and an improved user environment as the light conditions are optimised at all times. With individual control of fittings, it is very easy to reconfigure lights into different groups for new office layouts or other required changes.
  • There are several power control solutions that can help reduce costs and energy usage.
  • Power factor correction can improve the usable power available to equipment, and thus maximise its efficiency.
  • Active harmonic control removes harmonics and other noise from power lines, which saves energy and also reduces wear and tear on electrical equipment.
  • By scheduling production to off-peak times, and managing the electricity tariffs, you can use energy when it is cheaper, therefore reducing costs. You can also avoid penalties which may be incurred for taking electricity at peak times.
  • Another way to save money is real-time demand response, i.e. reducing load by stopping equipment or turning on a generator when the National Grid sees peak demand coming.
