Compact fluorescent bulbs provide as much light as regular incandescent bulbs while using just one-fourth the energy. A 15-watt compact fluorescent bulb yields the same amount of light as a 60-watt incandescent bulb. Compact flourescent bulbs last about 10,000 hours -- 10 times longer than incandescent bulbs.

Compact fluorescent bulbs provide as much light as regular incandescent bulbs while using just one-fourth the energy.

A 15-watt compact fluorescent bulb yields the same amount of light as a 60-watt incandescent bulb. Compact flourescent

bulbs last about 10,000 hours -- 10 times longer than incandescent bulbs.

Educational Campaign• Medium:

– Flyers• Focus on awareness,

visibility, convenience

• Message:– Student energy waste results

in Housing and Dining fee increase

– Student behaviors have global impact.

– Students can make small behavioral changes to make a positive difference.

• Targeted areas:– Lighting– Temperature control– Computer monitors– Laundry facilities

Where 2 begin with ????

When attempting energy savings…..the first place goes to lighting…Because…..

changes are generally easy , inexpensive and have a quick payback period…First step is to access current lighting conditions…. And measuring them against calculated updates will present the expected savings..

HOW TO ENABLE YOURSELF IN CONSERVING ELECTRIC ENERGY WITH SIMPLE STEPS

TURN OFF LIGHTS IN UNOCCUPIED AREAS.1. Post reminder stickers to turn off lights when leaving the area.2. Install time switches or occupancy sensors in areas of brief occupancy

and remote areas( warehouses, storage areas, etc).3. Rewire switches so that one switch does not control all fixtures for

multiple work areas.

USE LIGHT METER TO MEASURE LIGHTING LEVELS

1. Reduce lighting levels where appropriate.2. Reduce lighting hours.3. Employ uniform or task delamping to reduce power and lamping.

REVIEW OUTSIDE LIGHTING NEEDS1. Eliminate outdoor lighting where possible and where safety and

security are compromised.2. Manually turn off lights.3. Replace burned out lamps with lower wattage lamps.4. Replace exterior incandescent lights with more efficiency lights such

as high pressure sodium (HPS) or metal halide (MH).5. Install photoelectric or motion sensors where light needs are

intermittent.6. Ensure existing sensors function properly.

INSTALL MORE EFFICIENT BALLASTS Ballasts typically have a long life; therefore, replacing ballasts

that are still working can be one of the most cost-effective energy improvements.

Upgrade old ballasts as lamps are replaced.

Install electronics ballasts

REMOVE UNNEEDED LAMPS ( DELAMP)1. Remove fluorescent lamps controlled by magnetic ballasts in

pairs. 2. Remove unnecessary tubes and replace them with dummy

tubes that draw little current and provide the effect of uniform lighting.

3. Disconnect ballasts as the ballast will continue to use energy when the fixture is switched on.

INSTALL MORE EFFICIENT LIGHTING1. Replace incandescent lamps with compact fluorescent lamps ( CFL’s)2. Use single incandescent lamp of high wattage instead of two or more smaller lamps of combined wattage. Efficiency of incandescent lamps increases as lamp wattage increases.3. Replace non-destructive incandescent lamps with fluorescent or high intensity discharge lamps.4. Replace standard fluorescent lamps and ballasts with T8 and matching electronic ballasts (switching from fluorescent to high-efficiency fluorescent can save 10 to 30 percent in energy costs). 5. Replace fluorescent lamps with more efficient HPS lamps. 6. Replace mercury vapour lights with higher efficiency MH or HPS lamps.

EMPLOY MORE EFFECTIVE LIGHTING SETTINGS1.Lower fixtures or use a lamp extender to increase illumination on a given area. 2.Install reflectors or lenses to spread out and focus light (specular reflectors can improve efficiency by up to 17 percent in fluorescent lights). 3.Use light-colored paint on walls. 4.Ensure the layout of room is conducive to light and that light obstructions do not exist.

FOLLOW A REGULAR A MAINTENANCE SCHEDULE1. Establish a regular inspection and cleaning schedule for lamps and fixtures. 2. Establish a group relamping schedule to replace lamps as they burn out, usually done at 70 percent of rated lamp life. Group relamping will cut down on both energy and labor costs. Energy is still consumed while lumen output of fluorescent lamps decreases with age. 3. Replace yellow or hazy lens shading with new acrylic lenses that do not discolor. 4. Clean room surfaces such as tables, walls, etc. to remove dirt, increasing reflectivity.

USE DAYLIGHTING EFFECTIVELY

1. Locate workstations with high illumination needs adjacent to windows. 2.Turn off lights when daylight is sufficient. 3. Install light sensors/dimming equipment that automatically compensate for natural light variance. 4. Clean windows and skylights. 5. Reschedule housekeeping duties to operate during the day so additional after-hours lighting is not needed.

UPGRADE EXIT SIGNS WITH THE HELP OF AN EXPERT1. Retrofit by replacing incandescent lamps with CFLs. 2. Retrofit by replacing incandescent lamps with light-emitting diode (LED) lamps, which use one-tenth the electricity of incandescent lamps and have a lifespan of more than 100,000 hours. 3. Replace old exit signs with new LED signs

Energy efficient lightingTake advantage of daylight by using light-colored, loose-weave curtains on your windows to allow daylight to penetrate the room while preserving privacy. Also, decorate with lighter colors that reflect daylight.Use task lighting; instead of brightly lighting an entire room, focus the light where you need it. For example, use fluorescent under-cabinet lighting for kitchen sinks and counter-tops under cabinets.Use dimmers, motion sensors, or occupancy sensors to automatically turn on or off lighting as needed and prevent energy waste.Use compact fluorescent light bulbs (CFLs) in place of comparable incandescent bulbs to save about 50% on your lighting costs. CFLs use only one-fourth the energy and last up to 10 times longer.Turn your lights off when you leave a room. Standard, incandescent light bulbs should be turned off whenever they are not needed. Fluorescent lights should be turned off whenever you'll be away for 15 minutes or more.During winter, open curtains on your south-facing windows during the day to allow sunlight to naturally heat your home and close them at night to help keep the heat in.
