• 144 fixtures with 4 T8 fluorescent lamps.  Electronic ballasts. Switches not accessible
  
• 4 fixtures with 1 incandescent lamp each.  Switches accessible.
• EXIT signs - incandescent bulbs
  

Observations:

• Light levels appropriate
  
• Some light covers are dirty or cloudy
  
• No occupancy sensors.

• Advertising board (20 watts, but never plugged in)

Temperature:

• Not recorded

• Clean and/or replace dirty or missing light covers
• De-lamp lights in unused portions of cafeteria
• Replace EXIT signs with more efficient LED type.
  

Library

February 22, 2012.

Light level measurements:

• 100, 124, 89  Avg: 104.3

Fixture types:

• 60 fixtures with 1 T8 fluorescent lamps.  Electronic ballasts. Switches accessible
  
• No EXIT signs
  

Observations:

• Light levels very bright - lots of natural light from large windows
  
• Light covers clean, open
  
• No occupancy sensors.
  

Plug loads:

• Air conditioner (0.7 watts vampire, 178 watts ON.
  
• Computer (3.0 watts vampire, 33 watts ON.)
• Microwave (1.9 watts vampire, 1,371 watts ON.)
• Refrigerator (compressor cycle - 0 watts when compressor is off, 125 watts when compressor is ON)

Temperature:

• Not measured

• TURN OFF LIGHTS when there is enough natural light from outside to light the room. 
• Plug refrigerator into Kill-A-Watt meter for a week to get an accurate measurement of average energy use per day
• UNPLUG VAMPIRES at night and when they are not in use.  Install power strips to make it easier to fully cut all power. 
  

Gym  

February 22, 2012.

Light level measurements:

• 37.2, 67.0, 24.9  Avg: 43.0

Fixture types:

• 20 (?) fixtures with 1 metal halide lamps.  Magnetic ballasts. Switches not accessible.  Gym instructors said it takes about 15 minutes to warm them up. 
  
• 2 EXIT signs. Incandescent lamps.
  

Observations:

• Light levels variable and too low for competitive sports.  Some fixtures are broken causing dark spots.
• High windows provide little light.
  
• Light covers clean, open
  
• No occupancy sensors.
  

Plug Loads:

• None

Temperature:

• 66 degrees F

• Replace EXIT signs with efficient LED ones. 
  
• REPLACE METAL HALIDE FIXTURES.  Fixtures are old, very inefficient and many are broken.  Because of their long warm-up cycle, they are left on all day, regardless of whether or not the space is in use. 

Futures Office

February 22, 2012.

Light level measurements:

• 38.0, 57.0, 47  Avg: 47.3

Fixture types:

• Many fixtures with T8 fluorescent lamps.  Electronic ballasts. All lights on single switch.
• 1 desk lamp with incandescent bulb.
  
• no EXIT signs.
  

Observations:

• Light levels a bit too bright, but appropriate for a room without windows
  
• Light covers clean, open
  
• No occupancy sensors.
  

Plug loads:

• Printer (30 watts vampire, 1,200 watts ON)

Temperature:

• not measured

• UNPLUG VAMPIRES - especially printers!
• Change desk lamp to an efficient CFL or LED bulb.
  
• Study possibility of "de-lamping" lighting fixtures - taking bulbs out of overhead lights to decrease light levels to 30 footcandles.
