4 Potential Points Possible

Optimize Energy Performance

Lighting Power Intent

Achieve increasing levels of energy consumption below the prerequisite standard to reduce environmental impacts associated with excessive energy use.
Even though a lower wattage lamp may be used in a luminaire, the rated wattage of the luminaire must _______
be used in the calculation.
You have to ______ not just change the bulb wattage.
Change out the fixture.
In the ____________, areas enclosed by partitions 80% or greater than ceiling height may be considered as a separate area.
Space-by-Space Method
In the SBS Method three situations that permit increase to the interior power allowances are:

  1. chandelier-type luminaires
  2. lighting connected with visual display terminals
  3. lighting in retail spaces

For potential use during submittal revies, it is suggested that the project team compile and maintain floor plans showing:

  1.  the lighting layout
  2.  the schedule of lighting
  3. copies of the cut sheets indicating the rated wattage (keep copies)

For EA Table 1 If you install less thatn allowed then calculate the difference. You can achieve 2 points if your difference is:
greater than 25%
Interior Lighting Power Allowance
is the maximum light power in watts allowed for the interior of a building
Lighting Power Density (LPD)
is the maximum lighting power, per unit area, of a building classification of space function
Luminaire
is a complete lighting unit consisting of a lamp or lamps together with the housing designed to distribute the light, position and protect the lamps and connect the lamps to the power supply.
