Checklist for Reductions in Utility Costs
- 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.
- Turn lights off when not needed.
- Utilize daylighting as much as practical. Control window brightness with proper shades, drapes and so forth.
- Clean lighting equipment periodically and maintain in good working condition.
- Post instructions covering operation and maintenance of lighting equipment including proper type of bulb.
- Use light color finish on ceiling, wall, floor and furnishings for best reflectivity.
- Instruct service personnel to replace room bulbs with proper types, preferably Watt-Savers.
- Use energy-saving ballasts and fixtures for fluorescent lamps.
- Replace old incandescent lighting systems with more energy efficient fluorescent or HID systems.
- Rewire to provide more switches for turning on only those lamps needed rather than one switch for an entire area.
- Use high technology computer lighting controllers to maximize total energy savings.
- Use photocell controllers near windows to control fluorescent lighting for use of natural daylighting.
- Replace yellowed or low light transmittance fixture diffusers with high light transmittance diffusers.
- Reduce labor and maintenance costs by group relamping.
Other Electrical Savings
- Outdoor lighting includes the following applications: Signs, parking areas, building facades, landscape, decorative, pathway and walkway lighting.
- 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.
- Replace high wattage incandescent bulbs with Fluomeric (self-ballasted mercury) bulbs in outdoor floodlights.
- 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.
- 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.
Instructions for proper maintenance of air conditioning and heating equipment coming soon.
- 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.
* Set thermostats at 65-68 F. in halls and public rooms.
* Have service personnel set room thermostats at 55-60 F. in unoccupied rooms.
- Maintenance of Air Conditioning and Heating Equipment
* Maintain equipment in good condition, clean filters periodically, etc.
