Energy Saving “Treasure Hunt”
Arcade MiserPublic Domain
An important goal of Green Campus
Generation of measurable energy
Savings
• Each machine equivalent to
spotlight on 24/7 (120W)
• 10 machines in two locations
on campus
Ehow.com
Miser Overview
• Detects movement and powers up machine
• After 15 minutes of inactivity
the machine powers down
• Used frequently with Vending machines
Cost: ~$90.00

Depot Audit Findings
• Six machines
• ~1,750 kWh savings potential per
16 week semester
In Use10%
Not in Use90%
Arcade Energy Consumption
Traffic Issues with Sensor
• Misers are typically mounted in
the back of machines facing out
• High traffic
• Significant savings reduction
Whatisthemiser.com
Important Issue Before Trial
• Machines not owned by
HSU
• Permission by Rendezvous
granted
Traffic solution
• PVC mount built
• Sign made to notify gamers
of operation
HEY PROSPECTIVE GAMERS! These arcade machines are equipped with an energy saving device. To turn on the machines, simply swipe your hand in front of the motion sensor between machines. If you plan on playing a while, be sure to reload the juice by swiping your hand at least once every 15 minutes. Thanks for helping us save energy.
GOOD LUCK ON YOUR GAME!!!

Savings per Miser
• Savings per miser each
semester with same usage:
470 kWh, or $70 (78% cost)
• Payback for misers: 21
weeks
Right for My University?
Maybe, Maybe Not
• Owners may not be OK
with the machines
• loss of
visibility/revenue?
• Studies show no $ loss
from soda machines

However…
• Misers can be used on vending machines and most
plug-in devices
• We are fortunate to have the resources to implement
our own ideas to save energy and gain valuable
experience in creative problem solving!
• “Make as many mistakes as fast as possible”
Conclusion
This project has reduced
arcade machine consumption
dramatically with a fast, cheap
and easy solution.
There are opportunities everywhere
to reduce your campus’ energy
consumption. Public domain
