Steps to Creating a Sustainable Energy Strategy
•
•
EPA and DOE offer proven strategies for superior energy
management with tools and resources
EPA has developed a comprehensive tool kit based on the
successful practices of Energy Star Partners
– The tools and resources offered can assist your organizations in improving
energy and financial performance
Commit to Continuous Improvement
Assess Performance
Set Goals
Create Action Plan
Evaluate Progress
5
Commitment
• The common element of successful energy management
is commitment
– Need to allocate staff and funding to achieve continuous
improvement
• Appoint an Energy Director-sets goals, tracks progress
and promotes energy management program
• Establish an energy team-Executes energy management
activities across the organization-ensures best practices
are implemented
• Institute an Energy Policy-Provides the foundation for
setting goals and integrating energy management into an
organizations culture and operations
6
Action Plan
• Develop and perfect framework and profile methodology
and indicators
• Create planning committee involving various departments
including utility and operational personnel
• Start developing energy intensities and complete carbon
footprint
• Create historical and projected energy project opportunities
and methodology for screening such opportunities
• Evaluate best fit and overall energy savings opportunities
• Create asset-wide energy management steering committee
and develop work program
–

Assess Performance
•
•
Understand current and past energy performance to identify
opportunities to improve
Gather and track data-monthly utility bills, Kwh and therms
– Collect data by fuel type for each building
– Use actual not estimated data
– Use current data
• Track your data to compare the performance to similar
facilities
•
– Existing tracking system such as EPA’s Portfolio Manager will
organize and benchmark your facilities against your peers
Portfolio Manager removes the impact of weather and certain
operating characteristics to provide an apples to apples
comparison of energy performance
8
Portfolio Manager
• National performance rating is a benchmarking process
that helps energy managers assess how efficiently their
buildings use energy relative to similar buildings
• The following building types can be analyzed:
– K-12 Schools
Office Supermarkets Dormitories
– Hospitals Hotels Warehouses
Water Treatment
– Medical offices Courthouses
etc…
• Evaluate performance for the whole building, reflects
actual billed data, normalized for operation and provides
a peer group comparison
• EPA has developed an Energy Star performance rating,
with a rating of 75 defining the top quartile for eligibility
to apply for the Energy Star

UVA Success Story
University of Virginia-Rooting Out the Energy Hogs
• Metering and Benchmarking energy for facilities, space types
and systems are at the heart of the University of Virginia’s
(UVA) energy management program. With over 577 buildings
maintaining good data is key for understanding performance
and identifying areas for improvement.
• By analyzing meter and utility use information, UVA’s energy
management program identifies “energy hogs” that are
targeted as energy efficiency opportunities.
• Energy hogs are flagged by UVA’s tracking/trending program
whenever it detects high total utility use, or unusual utility use,
such as chilled water use during winter months for an office
building.
• Through its careful analysis of energy use information, UVA’s
energy management program was able to save $5 million in
2002

– Bill Data Verification
• (.5-1% savings)
– Tighter Procurement contracts
• (1-2% savings)
– Risk Management/risk Hedging Strategy development
• (3-5% savings)
– Retro-commissioning of facilities with elevated or increasing energy utilization
indices for both electric and natural gas consumption
• (3-5% savings)
– Facility equipment upgrades and design of energy efficiency into new
construction
• (5-10%)
* Estimates only

Lighting Tips
No Cost Measures
• Disconnect or remove lamps in
multiple lamp fixtures. This could
save upwards to 50% in lighting
energy
• Turn of lights in exterior offices
• Open blinds and shades for more
natural lighting
• Turn off lights when not needed
• Turn off signage and other lights
not necessary for security and
safety
• Clean fixtures and replace any
yellow or hazy diffusers
Low Cost Measures
• Buy fixtures that have a dimmer
to manually adjust light levels
• Install exit signs with Light
Emitting Diodes (LED). This would
save about 90% over an
incandescent bulb
• Install occupancy sensors in high
traffic areas (break rooms,
restrooms, conference rooms,
etc)
• As incandescent fixtures burn out
replace them with Compact
Fluorescent Lights, they have a
much longer life and consume
considerably less energy than
incandescent bulbs
• Install timers or controls on
lighting. This could save 10-15%
if used properly
14
Cooling Tips
No Cost Measures
• Turn your thermostat up to 78 degrees
• Use outside air as long as possible
before turning on your AC
• Avoid simultaneous heating and
cooling with multiple systems
• Caulk and fill cracks around doors and
windows
• Make sure outside doors and windows
are closed
• Use blinds and shades to prevent solar
entry and heat buildup
• Remove window air conditioners
where possible
• Continually check settings and
controls for proper on/off times
• Shift energy intensive operations to off
peak hours
Low Cost Measures
• Add controls to the exhaust fans to
shut them off when the building is
unoccupied
• Perform regular maintenance on
cooling equipment
–
•
•
Regularly clean condenser coils, change belts
and filters
Install an Energy Star programmable
thermostats that can automatically
raise temperatures during night and
off hours
When fan and pump motors need
repair, consider replacing them with
premium efficiency models and save
35-45% on your investment annually
Properly maintained systems can
save up to 30% of fan energy
and up to 10% of space
conditioning energy use
15
Office Equipment Tips
No Cost Measures
• Do not leave equipment in
sleep mode overnight because
it will continue to draw a
small amount of power
• Install free software from the
Environmental Protection
Agency that puts monitors in
sleep mode when not in use,
or :
•
– 1) go to start menu, 2) select
settings, 3) select Control Panel,
double click on Power Options, set
menus labeled “turn of monitor”
to 10 mins, “turn off hard disks”
to 20 mins, “system standby”
never
Low Cost Measures
• Choose electronic products
and appliances without a
built-in clock or timer. The
power supply in the appliance
is converting 120 Volts of
alternating current to low
voltage direct current which is
very inefficient.
• As the useful life of a
computer comes to an end,
replace with a laptop.
Laptops use 90% less energy
than a desk top computer
Turn off computer scanners,
printers and other devices
plugged into a power strip
when you leave the office

Demand Response
Value of Electricity
Demand response is a tariff or program established to motivate changes in electric
use by end-use customers in response to changes in the price of electricity over
time, or to give incentive payments designed to induce lower electricity use at times
of high market prices or when grid reliability is jeopardized.
•
Price-based demand response such as real-time pricing (RTP), critical-peak
pricing (CPP) and time-of-use (TOU) tariffs, give customers time-varying rates
that reflect the value and cost of electricity in different time periods.
•
Incentive-based demand response programs pay participating customers to
reduce their loads at times requested by the program sponsor, triggered either
by a grid reliability problem or high electricity prices.

Commissioning
Ensuring operability and integration of components and facilities
Quality Assurance
To maintain optimal performance over time, end-use equipment must be
“tuned-up” or commissioned to ensure that the equipment is operating as
intended.
There are a number of critical commissioning considerations that are
included in the commissioning process:
• Verified operation of the integrated system against the design
requirements
• Verified appropriate responses to transients
• Drawings and documentation verification and delivery
• Training acceptance and testing and training
• Final standards and codes verification
• Final quality control plan audit
• Environmental, Health and Safety Plan.
