Energy Efficiency Advice for Businesses 

• Operating ceiling fans in rooms with high ceilings will push rising air down in to the working area. This will reduce the need to increase the room temperature in the winter or use air conditioning in the summer. This also helps to maintain more uniform temperatures throughout the year.
  
  
• Use a motion sensor or digital timer switch for lights in infrequently used areas such as storerooms, hallways and washrooms.  
  
  
• Shut off computers, printers, coffee makers and photocopiers for the night and weekends. If computers must be left running overnight, shut off the monitor. Using dedicated circuits for equipment that must be left on makes it easier to turn off the power to other designated areas as required. 
  
  
• If possible, avoid using doors that exit directly to the outdoors. Use exit doors with enclosed entries, vestibules or revolving doors to help keep warm or cool air inside. Keep industrial doors closed when an inside area is being heated or cooled. If outside doors need to be open for longer periods of time, use insulating curtains to keep warm or cool air inside.  
  
  
• Consider lowering the temperature in unoccupied rooms or areas. You may even decide not to heat or cool unoccupied rooms at all. Programmable thermostats can be used to reduce the office temperature during evenings or weekends.  
  
  
• Replace your existing T-12 fluorescent lamps and magnetic ballasts with T-8 fluorescent lamps and electronic ballasts. They reduce up to 40% of energy costs, increase the system’s life, and improve the quality of light.
