Residential Plug Load Energy Simulation Using a Range of
Usage Profiles
Why simulation modeling?
Replaces costly experiments
Visualize and depict reality
Insightful system evaluations
2
Current Energy Simulation Practices
• DOE Software compliance: ANSI/ASHRAE/IESNA Standard 90.1-2007
• Regulation compliances purposes
• Effectively evaluates building envelop and large ticket items

Simulation Results
• Choosing Moderate mode will overestimate light use mode up to 3.36x
• Choosing Moderate mode will underestimate Heavy Use mode by 61%, or 3180.55 kWHr
• Schedule and power input impact linearly on TEC

Disclaimers
• This research is not indended to:– Evaluate device overall power consumption or feature-based
power consumption. – Evaluate device power qualities, although the measurements on
power factor and current harmonics data points are captured and saved.
– Provide references of comparisons among different models or brands of device in any aspect, nor to qualify the product for any level of incentives or certifications.
– Verify device functionality as described in the user manual, although the SOP may appear to cover many or all features of the unit under test.
– Provide inclusive device use profiles for testing, comparison, or discussion purposes.
