The DriversThe Drivers
• Increases in energy cost and volatility• Dominion increases due to rising
fuel costs• Need to Improve on the management
and planning of energy to create a more efficient energy management function
• Address growing convergence of energy, environment and sustainability issues. – Integrated assessments of
environmental, energy and service infrastructure issues
– Heavy reliance on energy data and system performance
Steps to Creating a Sustainable Energy Strategy
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 ImprovementAssess PerformanceSet GoalsCreate Action PlanEvaluate Progress

CommitmentCommitment
• 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

Action PlanAction 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– Monthly/quarterly meetings– Eventually develop a work plan– Complete a directory of energy expertise– Start out with questionnaire and complete needs assessment
and opportunity review.
Assess PerformanceAssess 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

Portfolio ManagerPortfolio 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 SupermarketsDormitories– 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 StoryUVA 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

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
• Turn off computer scanners, printers and other devices plugged into a power strip when you leave the office
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

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.

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.
