In Residence Business Plug Load Study
Goals of Experiment
- Measure power usage of In Residence Business office equipment.
- Educate others on what power requirements are of office equipment and how more efficient equipment may be obtained in the future.
Decisions to be made from Experiment
- How much to charge each in residence business for electricity usage.
Expected Outcomes
- Develop catalog of power requirements for laptops and other office equipment.
- Reduce plug loads over time.
Methodology
General
- Record information on owner of equipment and equipment rated power requirements.
- Record information from power adapter nameplate for V DC and amps (or milliamps) or watts.
- Plug equipment in Kill A Watt meter and plug meter into wall.
- Have owner of equipment perform normal work on equipment and record values in workbook for volts, amps, and watts.
- Check power usage in sleep and hibernate modes. Record in workbook.
- Keep monitoring for at least 2 hours and preferably 4 hours with computer under normal usage.
- At end of time period, record kWh and time elapsed before unplugging meter.
- Use kWh and elapsed time to calculate average watts.
- Watts may be used to calculate electrical usage fee for Green Garage Services billing.
Process Measurements
- Volts, amps, watts, kWh, time from meter.
Resources Required
- Kill A Watt meter
- Workbook to record data
Planning
Participants
- Laurie Catey
- Tom Brennan

Collaboration
- In Residence Businesses
- Jason Peet
Help Wanted
- Need someone to perform testing as businesses arrive at the Green Garage.
Scheduling & Sequencing
- T. Brennan requested measurement starting on 12/13/2011.
- Need to document refrigerator test before unplugging Kill A Watt meter, if used. - DONE
- Helen may have another Kill A Watt meter we can use instead. - DONE; Meter made available.
Observations
- Power in various modes
- Lowest power draw is solid state drive (power vs. capacity)
