					                                       New Construction Lighting Project-Level Summary
This worksheet calculates the annual energy savings and Conservation Rate Credit or Conservation Acquisition Agreement reimbursement
resulting from the installation of an energy efficient lighting system. The project-level economics; including savings after HVAC interaction,
busbar savings, O&M costs or savings, and periodic lamp replacement costs or savings, PV Life Cycle Cost and TRC B/C ratio are also
calculated.

 2-F32T8 - indicates two fluorescent lamps in a fixture designed for 4', 32 watt T8 lamps. The T
 indicates tube. The 8 indicates 8/8's of an inch (or a one inch) diameter tube.
 2800K - or 2800 degrees Kelvin (see Kelvin) is a typical color temperature for incandescent bulbs.
 Tungsten melts at around 3800 degrees Kelvin. Tungsten filaments become very fragile around
 2800 degrees Kelvin. Therefore, standard incandescent technology is limited to around 2800
 Kelvin CCT. At this temperature, the tungsten filament gives off a yellowish glow. Quartz
 Halogen is able to increase the color temperature to around 3100K. Because fluorescent technology
 does not depend on burning a filament to produce light, a wide range of color temperatures is
 possible.
 Annual Operating Hours - is usually a calculated value equal to the total weekday, weekend, and
 holiday hours that the lighting system is operating during a one year period.
 Color Temperature - or Correlated Color Temperature (CCT) is a measure of the light source's
 appearance to the eye. Color temperatures below 3000 degrees Kelvin indicate a yellowish, (or
 warm) tint. Medium color temperatures of 3500K indicate a neutral, whitish tint. Color
 temperatures above 4000K indicate a bluish, (or cool) tint. Kelvin is the absolute celsius
 temperature scale.
 Drop-Down - is a slang term for a spreadsheet or webpage that has drop-down boxes that allow a
 user to easily pick an item of interest.
 Efficacy - is a measure of a light source's relative efficiency. Measured in lumens per watt. High
 performance fluorescent lights have an efficacy greater than or equal to 95.
 Elec - indicates a standard electronic ballast. The electronic ballast drives the lamp(s).
 ESO - stands for Expanded Standard Offer. It is an expanded version of Bonneville Power
 Administration's Limited Standard Offer program. The ESO is designed to rebate end use power
 customers for significant improvements in lighting technologies and systems.
 Fixture - is the housing for the lamp, ballast, lens, and reflector. Fixtures screwed together (butted
 up against each other) can be considered separate fixtures.
 Fluorescent - is a lighting technology that produces light by exciting organic phosphor material on
 the inner wall of a glass tube or bulb.
 Foot-candle - One foot-candle is equal to one lumen spread over one square foot.
 HID - or high intensity discharge is a light source that produces light by creating an arc of
 electricity across two electrodes (think arc welding).
 High Pressure Sodium - is an outdated, very yellowish looking HID light source.
 HP - indicates high performance fluorescent products. So far, only T8 products have high
 performance capabilities. High performance is a generic term which is defined in the ESO contract.
 IES - The Illuminating Engineering Society is responsible for setting standards and providing
 engineering support for the lighting industry. IES produces a handbook that is considered the bible
 of the industry.

 Incandescent - was the first man-made, commercially usable, electrically driven light source
 invented by Thomas Edison over one hundred years ago. Basically, light is produced by burning a
 tungsten filament. When the filament burns, it gives off light. When the filament is burned out, the
 light goes out. Incandescent technology is limited to around 3100 degrees Kelvin because the
 tungsten filament cannot get any hotter without disintegrating.
 Kelvin - is the absolute Celsius temperature scale. Zero degrees Kelvin represents absolute zero.
 Zero degrees Celsius corresponds to 273 degrees Kelvin.
 Kilowatt - One kilowatt is = one volt * one amp * 1000 * power factor.
 kWh - is a unit of energy typically used in the electrical industry. It is equivalent to one average
 kilowatt acting over a one hour period.
 Lamp - is a generic term for an artificial light source.
 Lighting System - typically refers to all of the luminaires inside and/or outside of a building. The
 term is also used interchangeably with luminaire. It is desirable to look at a luminaire as a system.
 Lumen - is a measure of total light output of a lamp or luminaire.
 Luminaire - includes the lamp, ballast, fixture, lens, reflector, etc.. In other words, the whole
 lighting unit.
 Mean Lumens - or design lumens is an IES standard. Basically, the "mean or design" lumen output
 is the measured lumen output of the lamp or luminaire at 40% of the rated lamp life. To get the
 values used in the data tables, multiply lamp lumens * # lamps * bf * lumen maintenance factor.
 Mercury - is a heavy metal used in fluorescent and HID lamps to conduct electricity and excite the
 fluorescent material (phosphors).
 Mercury Vapor - is a very outdated HID light source. These are targeted for upgrade.
 Metal Halide - is a neutral white appearing HID light source.
 Phosphor - is a rare earth material that fluoresces under an electrical energy (ion) stimulus.
 Tungsten - is the metal with the highest melting temperature. Thus, it is well suited for lighting
 technologies. Tungsten melts at around 3800 degrees Kelvin. However, tungsten becomes fragile
 around 2800 degrees Kelvin (typical incandescent temperature).
 T8HP - a fluorescent tube 1 inch in diameter that has High Performance characteristics
