Checklist for Reductions in Utility Costs

1. Retrofit with reduced wattage, higher efficiency incandescent bulbs, compact fluorescent (Spiralux) and fluorescent tubes.
   * Watt-Saver light bulbs in 34W, 54W, 67W, 90W, 135W, and 185W will replace ordinary 40W, 60W, 75W. 100W, 150W, and 200W bulbs with very nearly the same light output.
   * Where decorative bulbs are used for "mood" lighting, use lower wattages.
   * Use ER-30 and ER-40 lamps in place of R-40 floods in deep-recessed HI-HAT fixtures. 67W and 90W ER lamps can replace 150W R-40 floods while providing the same or more light. Use 75W or 100W PAR-38 floods in place of 150W R-40 floods in regular fixtures.
   * Use Fluomeric (self-ballasted mercury) lamps in place of higher wattage incandescents for substantial power savings. · 160W Fluomeric replaces 200W incandescent · 250W Fluomeric replaces 300W incandescent · 450W Fluomeric replaces 500W incandescent · 750W Fluomeric replaces 1000W incandescent ·1250W Fluomeric replaces 1500W incandescent.
2. Turn lights off when not needed.
3. Utilize daylighting as much as practical. Control window brightness with proper shades, drapes and so forth.
4. Clean lighting equipment periodically and maintain in good working condition.
5. Post instructions covering operation and maintenance of lighting equipment including proper type of bulb.
6. Use light color finish on ceiling, wall, floor and furnishings for best reflectivity.
7. Instruct service personnel to replace room bulbs with proper types, preferably Watt-Savers.
8. Use energy-saving ballasts and fixtures for fluorescent lamps.
9. Replace old incandescent lighting systems with more energy efficient fluorescent or HID systems.
10. Rewire to provide more switches for turning on only those lamps needed rather than one switch for an entire area.
11. Use high technology computer lighting controllers to maximize total energy savings.
12. Use photocell controllers near windows to control fluorescent lighting for use of natural daylighting.
13. Replace yellowed or low light transmittance fixture diffusers with high light transmittance diffusers.
14. Reduce labor and maintenance costs by group relamping.

1. Outdoor lighting includes the following applications: Signs, parking areas, building facades, landscape, decorative, pathway and walkway lighting.
2. Control lights with photocells or time clocks set to come on a half-hour before dark and go off at dawn, or earlier, if feasible.
3. Replace high wattage incandescent bulbs with Fluomeric (self-ballasted mercury) bulbs in outdoor floodlights.
4. Use 60W yellow insect bulbs in place of 75 or100W bulbs. The lower wattage has the same anti-bug effect with considerable savings in electrical energy.
5. Replace 150W R-40 reflector floodlights with 75W Par-38 floodlights to provide the same light level at 50% lower energy costs. The Durex hard glass in PAR-38 bulbs assures satisfactory service even in open units outdoors.

1. Air Conditioning
   * Have service personnel turn off air conditioning in unoccupied rooms.
   * Set thermostats at 78-80 F. in halls and public rooms.
   * Keep windows and doors closed, drapes drawn where practical.
   * Reduce air conditioning electric costs by reducing lighting costs. Example: $1500 annual savings in reduced lighting load results in additional savings of $500 in air conditioning costs.
2. Heating
   * Set thermostats at 65-68 F. in halls and public rooms.
   * Have service personnel set room thermostats at 55-60 F. in unoccupied rooms.
3. Maintenance of Air Conditioning and Heating Equipment
   * Maintain equipment in good condition, clean filters periodically, etc.
