ENERGY STAR OVERVIEW
• Voluntary, public-private partnership
• Recognized, trusted symbol
• Credibility of EPA and DOE; enhanced testing and
verification through 3rd party accredited labs
• Program Goals:
– Reduce energy use
– Reduce greenhouse gas emissions and other air pollutants
• Vast network of Partners (more than 17,000)
• Large savings (as of 2010):
– saved Americans ~ $18 billion on their utility bills
– avoided 170 million metric tons of greenhouse gas emissions = to
annual emissions of 33 million passenger vehicles

ENERGY STAR PROVIDES MARKET-BASED
STRATEGIES . . .
Barriers (e.g.)
Strategies to reduce barriers (e.g.)
Lack of information
Consumer/end user outreach and education
Lack of demand
Education/consumer testimonials/case studies
Coupling efficiency w/other benefits/features
Lack of availability of energy efficient product or
service
Establish measurement standard
Designate high performers as ENERGY STAR
through collaborative process (as relevant)
Recognize achievement
Supply channel education
Higher first cost
Increase demand to drive costs lower over the
long-term
Consumer education on “two price tags”

BENCHMARKING WITH PORTFOLIO MANAGER
WHAT IS BENCHMARKING?
Benchmarking provides…
• A method to compare the energy use of
similar buildings over a given period of
time.
• The ability to conduct an “apple to apple”
comparison using data to assess a
building’s relative energy performance in
comparison to the energy intensity of other
known buildings.
14
EPA’S BENCHMARKING TOOL
The US Environmental Protection Agency (EPA’s) ENERGY STAR®
Portfolio Manager:
• Is a free secure online energy management and tracking
tool to help commercial buildings benchmark their
energy usage
• Allows tracking and assessment of energy and water
consumption of a single building or across an entire
portfolio of buildings
• Can help a building owner or manager set investment
priorities, identify under-performing buildings, verify
efficiency improvements, and receive EPA recognition for
superior energy performance
15

USING PORTFOLIO MANAGER TO SET
INVESTMENT PRIORITIES
• Identify under-performing buildings to target for energy efficiency
improvements first.
• Establish a baseline to track progress over time

PORTFOLIO MANAGER PROVIDES:
For All Commercial Buildings:
• A weather normalized and non-weather normalized Energy Use
Intensity (EUI) values (kbtu/square foot) and annual energy
consumption (kbtu)
• Direct, indirect and total greenhouse gas emissions
• Ability to track financial performance information
• Tools to set baselines & goals for % improvements over time
• Reports and graphs to assess trends
• Data for compliance and participation with a variety of emerging state,
local, and federal regulations and voluntary programs
For Eligible Buildings (As Defined By Portfolio Manager):
• Eligible building types can also receive an ENERGY STAR energy
performance rating of 1-100

creating a "green" house of
Some Energy Savings Measures
worship was a high priority
Included:
• The building square footage
• High-efficiency gas-fired condensing hot water boiler
• Individual temperature control for all space
increased 25% percent and
• Variable frequency drives for the hot water heating pumps and

CINCINNATI, OHIO
• Used the ENERGY STAR Guidelines
for Energy Management to develop
an energy plan and establish a
continuous energy management
process
• Began with a Portfolio Manager score
of 64 in January 2008 and increased
to 82 by March 2010
• Energy efficiency measures included:
• Low cost/no cost measures
• Recalibrated the thermostats
• Improved the entire building's
temperature automation, which
negated the need for personal
desk fans and heaters
• Achieved annual savings of
$8,500 (115,000 kWh & 40,000
cubic feet of natural gas)

ELEPHANTS DELICATESSEN
PORTLAND, OREGON
• Started out by consulting the
ENERGY STAR Guide for
Restaurants
• Used Portfolio Manager to measure
and track their energy usage (EUI)
and help determine an energy
management plan
• Worked with the local utility to make
upgrades and earn incentives
• Energy efficiency measures included:
• Replaced T12 fluorescent fixtures
with new T8 fixtures and installed
CFLs for a 50% saving in lighting
cost and an ROI of only 1.2 years
• Replaced commercial kitchen
equipment with ENERGY STAR
qualified equipment
