Recommendations

Main Lobby
(outside cafeteria)

February 22, 2012.
Light level measurements:
  • 44, 13, 118.  Avg: 38.2
Fixture types:
  • 16 fixtures with 6 T8 fluorescent lamps.  Electronic ballasts. Switches not accessible
  • 14 fixtures with 1 incandescent lamp each.  Switches accessible.
  • 3 EXIT signs - type of lamp unknown.
Observations:
  • Light levels quite variable - lighter in some spaces and dark in others.
  • Light covers are clean
  • No occupancy sensors.
Plug Loads:
  • None

Temperature:
  • 68.5 degrees F
Recommendations:
  • Replace inefficient incandescent lamps with efficient CFL or LED bulbs.
  • Balance light levels in room
  • Check EXIT signs.  Replace if incandescent type.
  • Keep light covers clean.   

Cafeteria

February 22, 2012.
Light level measurements:
  • 38.2, 20.7, 37.8  Avg: 32.3
Fixture types:
  • 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.
Plug loads:
  • 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.

Mr. Hartman's Science Lab
(RFL room 204)

February 22, 2012.
Light level measurements:
  • 29, 37, 46  Avg: 37.0
Fixture types:
  • (How many?) fixtures with 2(?) T8 fluorescent lamps each.  Electronic ballasts. Switches accessible - lots of options for light levels (great!)
  • 2 EXIT signs - LED lamps (1.6 watts)
Observations:
  • Light levels appropriate
  • Fixtures in back of room on, but not necessary.
  • Lots of windows, but covered to reduce glare
  • Light covers clean, open
  • No occupancy sensors.
Plug loads:
  • Smart Board (5.0 watts vampire, 296 watts ON.  6 hours per day, 180 days)
  • Wireless router (0 watts vampire, 4.5 watts ON 24/7/365)
  • Goggle UV cleaning cabinet (9.9 watts vampire, 17.8 watts ON.  rarely used.  now unplugged)

Temperature:
  • 76 degrees F
  • CUT POWER TO VAMPIRES!  Smart Board and computer are plugged in 24/7.  Make sure electricity is cut at the power strips.
  • TURN OFF THE LIGHTS unless there is a need..
  • Open the blinds to allow in natural light
  • Keep goggle cleaner unplugged unless not in use.
