Caught On The Rise

“Escalators chewing up dollars and sense”

A Case Study by Kevin Chao, Sarah Oaks,

Lee Rommes, & Sarah Thomas

Valley River Center, Eugene, Oregon. March 19th, 2007


Introduction
Introduction

  • Escalators are a great convenience, but what do they cost us? For our case study, we explored how much time the mall escalators at the Valley River Center were being used, directly reflecting what percentage of the energy put into the escalator is wasted on a daily basis.

A case study by:

Walter Grondzik, Daniel Faoro, & Alison Kwok

12-hour use interval

[$1.488/h (cooling) + $0.414 (motor)] x 12 hours = $22.824 per day

On a year

$22.824 per day x 365 = $8,330.76


Hypothesis
Hypothesis

  • Constantly running escalators are not occupied during 50% of observed - - - business hours, resulting in energy losses.

Conclusion
Conclusion

Escalator Resource Misappropriation

After reviewing the data, we have found that we met our hypothesis that the escalators were being used less than 50% of the time at the Valley River Center Mall; therefore the escalator is not properly designed for the space and wastes energy when not in use.
