Simple Energy Savings Solutions - Elevator Relamping

In the Facilities Management and Commercial Building Maintenance industries we attempt to save monies for our organizations in any way that we can. When it comes to attempting to become energy efficient, in many cases it is good to start with simple projects that can illustrate the savings that can be accomplished with energy efficient applications.

I have a simple Energy Efficiency savings solution that I would like to share with you. I was recently in a mall in Los Angeles and I discovered a simple solution that we could all utilize that has a very low capital investment with a large ROI. I got on an elevator of the first floor and I had to take it to the 4th floor to get to a store I liked. The elevator was crowded so there would be stops on each floor. I noticed that the elevator was extremely hot and I became very uncomfortable. The reason being is that the Halogen lamps in the cab produced a lot of heat. These lamps almost resemble an 'Easy Bake Oven.' The elevator had 6 Halogen Par lamps that were 50 watts each. This is a huge waste of energy. Electronic Lighting Science, Inc. (ELS) produces an LED lamp with the same light output of a Halogen that utilizes only 5 watts of energy. The LED lamp has very little heat, which contributes to passenger comfort. Also,  LED lamps last 20 times longer, which reduces maintenance costs in the long run.  I decided to perform a simple economic analysis to see what the true benefits of switching to LED in elevators would be and here is what I discovered:

 

The Danger Lurking in Compact Fluorescent Light Bulbs

By Deirdre Imus
Published March 07, 2011

You see them in every grocery store and home center - those funny-looking curly compact fluorescent lights (CFLs) that are rapidly replacing the old round bulbs. And pretty soon, the Energy Independence and Security Act of 2007 kicks in, requiring bulbs to be 25 to 30 percent more efficient by 2012 to 2014, and 70 percent more efficient by 2020, effectively phasing out traditional incandescent bulbs as a way to save energy and reduce greenhouse gas emissions.

The energy efficiency of CFLs may be significant, but unlike traditional light bulbs, there is a hidden danger sealed inside each little bulb that requires special handling and disposal.

So what does that mean if a CFL is cracked or breaks in our homes, releasing mercury vapors in an enclosed area? Read More>>>

Elevator Retrofit Savings Analysis

  • In most cases Elevator lights run 24 hours per day, so based upon the average kWh expense for California of $0.1633/kWh, and organization spends roughly $429.15 a year in energy cost per elevator
  • Most Commercial Buildings operate 6 to 10 Elevators per building.
  • Halogen and Fluorescent lamps contribute to passenger discomfort and increased HVAC expenditure
  • Halogen and Fluorescent lamps have short life spans, which increase maintenance cost.
  • LED last roughly 20 times longer than Halogen and Fluorescent lamps.

ROI and Environmental Impact Data

  • The estimated Payback period for the LED retrofit project is 0.26 years.
  • 5 Year Cash Flow is estimated to be $1,830.78.
  • ROI for this investment estimated to be 378.66%.

Final Analysis

  • One can retrofit an elevator with LED for less than $120.00 USD.
  • You can reduce your expenditure per elevator from roughly $429.15 to $42.92, which is a 90% reduction in energy
  • With an average building having 6 to 10 elevators, you could save roughly $4,000 per annum with an elevator lamp retrofit.
