What is ENERGY STAR? Voluntary climate protection partnership with EPA Strategic approach to energy management, promoting energy efficient products and practices Helps organizations save money and protect the environment Influential brand recognized by over 75 percent of Americans Helps bring supply and demand together to advance energy efficiency
Working with K-12 School Districts A roadmap to help organizations Assess energy performance Set reduction goals Track savings over time Recognize improvements 5
Key Tools and Resources for Schools Help schools achieve measurable energy efficiency Portfolio Manager - www.energystar.gov/benchmark Building Upgrade Manual - www.energystar.gov/ia/business/epa_bum_full.pdf Cash Flow Opportunity Calculator - www.energystar.gov/ia/business/cfo_calculator.xls Training web-based and in-person workshops - www.energystar.gov/training Expert Help: Service and Product Providers - www.energystar.gov/spp Recognition: improvements and top performance 6
Benchmarking Benchmarking through ENERGY STAR allows you to: Compare one building against a national sample of similar buildings Compare all of your buildings of a similar type to each other Set priorities for use of limited staff time and/or investment capital
Benchmarking Portfolio Manager Benchmark the energy use of all of your buildings Receive an energy use intensity (EUI) for each building. Many buildings are eligible to receive energy performance scores on a 1-100 scale. Track changes in energy and water use over time in a building, groups of buildings, or entire portfolios Normalized for weather, operating hours, occupant density, plug load Track and report cost savings and CO 2 emissions Apply for the ENERGY STAR certification www.energystar.gov/benchmark
Identify Priorities Across Portfolios High scoring buildings provide ENERGY STAR Certification candidates Lighting improvements will yield savings and certification candidates Comprehensive investment opportunities where there is the greatest potential for whole building improvement Reward & Learn High Return Invest Invest Deeper 50 75 25 100 PropertyID DataYear Source Currency ChainID MgmtCoID OwnerID OwnerTypeID SumOrDetail WhoModified LastModified MktMixBus MktMixTourist MktMixSmMtg MktMixG rpmtg MktMixOther MgmtCoID PropertyID DataYear Source Currency ChainID MgmtCoID OwnerID OwnerTypeID SumOrDetail WhoModified LastModified MktMixBus MktMixTourist MktMixSmMtg MktMixG rpmtg MktMixOther LastModified MktMixBus MktMixTourist MktMixSmMtg MktMixG rpmtg MktMixOther MgmtCoID PropertyID DataYear Source Currency 1 Portfolio in Benchmark Order

Lighting A Major Component of ENERGY STAR Building Upgrade Manual Benchmark Benchmark Benchmark Benchmark Benchmark
Efficient Lighting Moves the Needle on Energy Performance Scores Lighting accounts for up to 35% of building energy use Lighting efficiency upgrades can reduce lighting energy use by up to 50% * Therefore lighting efficiency upgrades can cut total energy consumption by about 17% Portfolio Manager scores can increase up to 17 points! ** * Depends on initial efficiency of lighting, extent of lighting upgrade, etc. ** Estimated figure based on statistical principles. Varies by space type and building.
Lighting efficiency Lighting efficiency is typically considered an energy efficiency low-hanging fruit. Simple & Inexpensive Switching off lights Delamping Cleaning Daylighting Investment Projects Relamping Install dimmers Timers Sensors
Switching from T-12 to T-8 lighting Lamp improvement: Lamp smaller diameters Increasing lamp / ballast system efficiencies Longer lamp life Better color rendering index (CRI) Reduced mercury
The case for upgrading!
Lights Out for T-12 Fluorescent Lamps Since July 1, 2010, a U.S. Department of Energy mandate states that the magnetic ballasts used in many T-12 fixtures will no longer be produced for commercial and industrial applications. Additionally, many T-12 lamps will be phased out of production beginning July 2012.
Switching from T-12 to T-8 lighting requires a ballast upgrade Ballast is a device intended to limit the amount of current in an electric circuit, to light a fluorescent lamp Magnetic ballasts (or T-12 magnetic ballast) older technology with a core of steel plates wrapped in copper windings. Pre-1979 ban on PCBs, these ballasts incorporated a small capacitor that contained PCBs. Electronic ballasts considerably more energy efficient than magnetic ballasts. T-8 lamps use electronic ballasts to operate effectively. These are the ballasts used in new and retrofit projects.
PCB-Containing Ballasts Schools built prior to 1979 Widespread leaking of PCB-containing lighting ballasts nation wide PCB-containing Ballast
Where and how much PCB in ballasts? An older ballast has a transformer to reduce voltage, a small capacitor that may contain PCBs, and some have a thermal cut-off switch and/or safety fuse. A tar-like substance, potting material, is used to surround components to muffle the noise of the ballast. If PCBs are present in the capacitor, the amount ranges from approximately 1oz to 1.5 oz The ballasts for high intensity discharge (HID) lamps can contain between 3 oz and 14 oz PCBs
Health and Safety Issues An experienced contractor or staff should be the only ones working on potential PCB lighting fixtures Follow standard operating procedures for working around electrical fixtures as required Follow all requirements and precautions if there are asbestos issues. Move desks and equipment from underneath the fixture Place plastic sheeting under the work area
Proper storage and disposal Disconnect and remove all ballasts, incidental PCB-contaminated items, and fluorescent tubes from the lighting fixture housings and compartments; Provide the appropriate containers and packing materials for packaging and storing the four possible types of waste streams: Intact, non-leaking, PCB-containing ballasts; Leaking PCB-containing ballasts and cleanup wastes generated by handling and decontaminating areas where leaking ballasts were discovered; Ballasts that contain no PCBs; and Fluorescent light bulbs.
Proper storage and disposal continued - Maintain a record for each space where lighting fixtures are removed including how many leaking vs. non-leaking PCB-containing ballasts were removed from each space Package and label drums according to federal, state, and local regulations. Store the drums until a transporter currently licensed for transportation of PCB waste removes them to the appropriate disposal facility. Ballasts that are totally enclosed and not leaking can currently be disposed of in a solid waste landfill. However, most landfills will not accept such waste so most will be disposed of in a TSCA approved landfill or destroyed using chemical or thermal destruction methods. http://www.epa.gov/wastes/hazard/tsd/pcbs/pubs/ballasts.htm
Lighting Action Plan / Once Establish voluntary teacher/student program to turn off lights to save energy Install building automation system to monitor lighting energy use Install timer controls, photosensors, and motion sensors where appropriate, especially in occasionally used spaces* Install dimming ballast if appropriate and compatible with lighting system Install LED lights on exit and emergency signs
Lighting Action Plan / Daily Turn off lights in unoccupied rooms** * Turn off all lights at night with the exception of security lights and exit signs, as safety considerations allow* Turn outdoor lights selectively, as safety considerations allow* Delay turning lights on in the morning until staff arrive*
Lighting Action Plan / Monthly Check that all interior and select exterior lights are turned off during nights Analyze lighting building automation system for opportunities to decrease lighting electricity use Check for broken lamps and replace
Energy Efficiency Opportunities Low-Cost Measures Measure and track energy performance. Set back the thermostat in the evening and other times when the building is unoccupied. Perform monthly maintenance of heating and cooling equipment to guarantee efficient operation throughout the year. Educate students and staff about how their behaviors affect energy use.
Energy Efficiency Opportunities Cost-Effective Investments Upgrade and maintain heating and cooling equipment.* Use performance contract to guarantee energy savings from upgrades. Work with energy services providers to help manage and improve energy performance. Purchase energy-efficient products like ENERGY STAR qualified office equipment. Install window films and add insulation or reflective roof coating to reduce energy consumption.
