How can energy consumption in houses be reduced by the use of LED (light emitting diodes) in lighting design?
Purpose:
To investigate how much energy can be saved using LED lighting instead of conventional lighting applications.
Goals and objectives of the project:
To conduct a cost analysis comparison between an incandescent lighting design and a low voltage LED lighting design in a standard house to produce a cost difference report.
Methodology and analytical approach:
I. Establish an average bulb of both LED and incandescent from common types.
a. Determine best option for LED bulb
b. Determine best option for incandescent bulb
II. Calculate lumen output
a. LED
b. Incandescent
c. Adjust amount of lights to produce equal lumen output
III. Calculate cost analysis
a. LED
i. Determine efficiency
ii. Determine installation cost
iii. Determine replacement cost
1. Life length
2. Bulb cost
b. Incandescent
i. Determine efficiency
ii. Determine installation cost
iii. Determine replacement cost
1. Life length
2. Bulb cost
IV. Compare results
a. Calculate a “pay-off length”
b. Research the use of LED lighting in houses being built
