Plug Loads Defined

  • Typical office

equipment but also includes appliances, chargers, task lighting, portable heaters, vending machines, holiday displays, etc.

Everything that plugs into a receptacle

Plug Load Energy Use

Plug load energy use for computers and office equipment is increasing. In

  • ffice buildings that have

improved the efficiency of lights, heating and cooling, it can represent as much as 50% of the total electricity use.

Plug Load Policy ?

  • What equipment is

allowed?

  • Enforcement –

Who is responsible?

  • New equipment

energy use

  • Laptops? (Bring

your own device)

  • Surge protection?

Benchmarking Plug Loads

“You can’t manage what you don’t measure”

  • The foundation of sound and sustainable energy management

Monitor Btu (more control) vs. Monitor $ (less control)

slide-11
SLIDE 11

Plug Load Inventory

¡ ¡ • Use power plans to organize the walkthrough

  • Use a data collection form
  • Have employees complete form for their
  • ffice
  • Interns?

Case Study – Stanford University

  • 86% of campus inventoried
  • Ten buildings consume 30% of total campus

plug load consumption

  • Largest “energy hogs” were servers, lab

freezers, and space heaters

  • Plug loads are 22% of total campus

electricity use

  • Inventory informed new building electrical

infrastructure and cooling system sizing

slide-13
SLIDE 13

Measuring Plug Loads

  • Develop a metering plan
  • Electric panel vs. receptacle
  • vs. equipment load
  • What equipment cannot be

turned off for metering

  • Prioritize equipment types

for metering

  • Health and safety issues
  • Shutdown procedures
  • Reconfiguration

requirements on start-up

slide-14
SLIDE 14

Simple Measurement

  • Watts, Amps, Volts, Kilowatt

Hours, Power Factor

  • Relatively low cost ($25 to

$125)

  • Built-in surge protection
  • Cumulative energy use
  • No time stamp (no logging

capability)

slide-15
SLIDE 15

Data Loggers

  • Time stamp with

kwh use data

  • Able to store and

download data to computer for analysis

  • Easy to deploy for
  • ne week intervals
  • Use 30 second

intervals to measure parasitic losses (idling)

¡

slide-16
SLIDE 16

Submetering

  • Receptacle circuits or

panels

  • Able to store and

download data to computer for analysis

  • Ability to interface with

Building Automation System

  • Licensed electrician

required for install

5 Steps For Managing Plug Loads

  • 1. REVIEW. Inventory your equipment and focus
  • n the devices that use the most energy
  • 2. REMOVE. Eliminate or unplug unnecessary

devices

  • 3. REPLACE. Purchase the most energy efficient

devices for the job

  • 4. REDUCE. Turn it off or power it down when not

in use

  • 5. RETRAIN. Engage staff. Make sure they

understand why, when, and how to power down

Power Management

¡

Source: ¡NBI ¡Plug ¡Load ¡Best ¡Prac1ces ¡Guide ¡

  • Enable aggressive

power management settings

  • Stay on top of your

settings

  • Activate sleep settings

across a network of computers

  • Consolidate/centralize

printing, fax, copying services

¡

slide-21
SLIDE 21

Advanced Plug Strips/Timers

¡• Occupancy sensing

  • Plug strips with integral timer
  • Smart strip with programmable

scheduling and metering

  • Timers for food service equipment
  • Switched receptacles
  • Vending miser for vending machines

Occupant Behavior

¡Remember: Buildings don’t use energy, people do

  • Keep office staff well informed
  • Offer training on new devices
  • Communicate why managing plug loads is important
  • Consider friendly competitions that reward reductions in

energy use

  • Encourage staff to get into the habit of thinking about

energy

  • Implement an “energy minute” at staff

meetings to discuss energy use

  • Check with staff frequently to find out if

everything is working-if not, determine why and work to find a better strategy
