  • As school budgets get tighter, more people are realizing that many of the items on a typical school budget is not optional. Energy cost may be one of the last areas where adjustments can be made without compromising personnel compensation or quality of service.
  • Natural gas wells are being capped. Power generation plants are being mothballed.
  • Example 1: New School building with regular power quality problems. Motors burning out, light fixtures failing early. Two years after construction, it was discovered that the a power conditioner was installed as part of the original construction, but was never turned on.Example 2: Public school built around 1975 with pneumatic controls, with consistently high heating bills and increasingly more difficult to control temperature. Detailed physical inspection of unit ventilators revealed that in prior years as pneumatic controls failed, the outside air dampers where hardwired in the open position (either 100% or 75% open).
  • Ensure thermostat setting equals actual space temperature
  • Reduce outside air requirements by adjusting dampersto minimize the need to condition outside air (within codes)
  • 1. Energy Start and SIEU study recommends the use of occupancy sensors to ensure that cleaning staff turns off the lights when they leave an area.2. Joe Serna Jr (office building). Instituted day cleaning with hours from 11am to 8pm during 2001 energy crisis. Savings of 8% Total Building Energy
  • Every year Americans use 4 billion kWh to brew 30 billion pots of coffee.Smart Powerstrips
  • Sponsor PostersPromotionalEvents, Energy TipsSheet, CompanyNewsletters, CompanyAnnouncements, Informational Posters
  • ENERGY STAR labeled computers, copiers, external power adapters,fax machines, laptops, monitors, multifunction devices, printers,scanners, water coolers, and more
  • Harvard University – Deployed EPA Power Management software across it’s network of 800 computers using 1 technician working for ½ a day.
  • 1. Light loss factor resultingfrom dirt and dustaccumulated on light fixturesand lamps2. Light loss factor resultingfrom dirt and dustaccumulated on light fixturesand lamps
  • Make sure OC doesnot take the place of good habits. Evergreen Public Schools – Vancouver WA – found that the extra 10minutes on the motion sensor after everyone left their room could be translated into 12,000.00/year. They adjusted their timing to be closer less than the original 20 minutes.

    2. 2. Agenda Making the case for energy efficiency Understanding your district’s energy bills Renewable energy and alternative technologies Understanding funding opportunities Identifying low cost/no cost opportunities to reduce cost 2
    3. 3. 1Making the case for energy efficiency 3
    4. 4. Why is Energy Management Important? “Good Energy Management is Good Business”The evidence is clear that for both public and private k12 schools, adopting an energy management strategy is a business decision you cannot afford to ignore. 4
    5. 5. Signs of Energy Waste in Commercial Buildings A 400% variation in energy use intensity of buildings in the United States exists that is not explained by age, technology, hours, size, climate. Little improvement of overall energy consumption has been seen although building components are 30% more efficient since 1980. Over-sizing of building fan systems, on average, occurs by 60%. Most chillers are oversized by 50–200%. • - EPA 5
    6. 6. Signs of Energy Waste in K12 Buildings EPA/Energy Star Statistics:  The annual energy bill to run America’s primary and secondary schools a staggering $6 Billion. $1 out of every $4 spent on energy by US schools is wasted. Conservative 25% = $1.5 Billion annually.  Energy cost total between 1.5% to 3.5% of a typical school district’s annual budget. Energy is often second only to staff salaries – more than computers and textbooks combined.  The least efficient schools use three times (3x) more energy than the best energy performers  Top performing ENERGY STAR labeled schools cost forty cents per square foot less to operate than the average performers. 6
    7. 7. Strong Energy Management = Real Savings Ford Motor Company has saved over $75 million through effective energy management. Eastman Kodak saved more than $8.6 million in operating costs in 2002 from its energy management efforts. Fairfax County Public Schools (VA)estimates an annual energy savings of $4.5 million (7.19%) from energy efficiency improvements on a $62.6 million utilities budget (FY: 2011-12) In 2001, the first year of their Energy Management program, Sandy Creek CSD (NY) saved $300,000 on a $1.4 Million utility budget (~21%). Total of $2.7 Million in savings from 2001 to 2009. 7
    8. 8. Pending Crisis Due to the recession, demand for energy supply is down, resulting in the lowest cost per unit of electricity in the last decade. Natural gas is also seeing record lows.This is a TEMPORARY condition. Over time, usage demand will return and cost/unit will rise) Utility delivery (NYSEG, etc)companies are starting to shift rate structures to put a greater emphasis on peak demand usage. Over the next 5 years or so we can expect to see increasing peak demand charges and an elimination of the differential between day and night rates. When usage demand returns, we will be impacted by both increased cost/unit and increased peak demand charges 8
    9. 9. Accessing Potential Lost Dollars By systematically implementing an Energy Management Plan, many school districts have been able to reduce energy consumption by 30% to 40%. The first 10% of reduction in energy use is possible with little or no cost. 9
    10. 10. EPA’s Strategy for Creating an Energy Management Plan  STEP 1: Make Commitment  STEP 2: Assess Performance  Step 3: Set Goals  Step 4: Create Action Plan  Step 5: Implement Action Plan  Step 6: Evaluate Progress  Step 7: Recognize Achievements 10
    11. 11. Key Elements of an Effective Energy Management Plan District wide energy related mission statement Defined heating /cooling set points and setbacks Defined access hours for midweek and weekends Defined path for requesting exceptions Adoption at the highest effective level of the District Identify local “Energy Champions” Easily measurable specific energy target (at the level of utility metering) Peer based energy targets – EPA Portfolio manager scoring, NYCHIPS, 11
    12. 12. Resources See Auxiliary Docs: “EPA_Guidelines_for_Energy_Management “ www.energystar.gov/index.cfm?c=guidelines.guidelines_index www.energystar.gov/index.cfm?c=evaluate_performance.bus_po rtfoliomanager www.energystar.gov 12
    13. 13. 2 Understanding your district’s energy bills1. Anatomy of a Utility Bill2. Using Utility Data 13
    14. 14. Anatomy of a Utility BillThanks to deregulation laws in NYS, our primary utility bills (electricity and natural gas) are split into two sections: DELIVERY SUPPLY Responsible for physical  Provider of the actual energy delivery of energy and usage  Ex: NYSEG Solutions, Direct metering. Energy, MEGA, etc. Owner of the power lines, gas piping and onsite meters Ex: NYSEG, RGE, etc. 14
    15. 15. Potential Billing Issues Miscellaneous Charges  Manual download charges on interval meters Demand Charges  Do they appear to be reasonable ? Quantities and Volume  Verify that the figures for kwh, KW and therms of natural gas agree between the supply and delivery companies. Electricity should be 1-to-1 and Natural gas should be +- 1.0%. 15
    16. 16. Using Utility Data-Utility Bill Tracking and Analysis (Monthly)  Maintain a copy (physical or electronic) of all utility bills for use by the Facilities Department.  Record monthly billing data including unit cost, quantity and weather information  Compare usage to similar prior periods to identify maintenance issues, etc.  Software Tools:  MS Excel, EnergyWatchdog, SchoolDude/Utility Direct, 16
    17. 17. Using Utility Data-Benchmarking (annually) Confirm savings from energy conservation investments Compare a building’s normalized performance vs. internal and external peers Software/Service Examples: NYSERDA’s Benchmarking program, EPA Portfolio Manager 17
    18. 18. 3Renewable energy andalternative technologies 18
    19. 19. Renewable Energy Pros and Cons Solar and wind make good educational demonstration projects Often fail to save significant amounts of energy and do not provide reasonable pay back periods Things to look for:  Life of equipment/Maintenance schedules vs. payback periods  Have we fully explored all other energy conservation options for our buildings? 19
    20. 20. Alternative TechnologiesLeading Edge vs. Bleeding Edge Leading Edge Bleeding Edge T8 & T5 lighting  LED interior lights Modulating/Condensing  Heat reflective white roofing Boilers  Waterless urinals HVAC control software  Geothermal heating and Occupancy controls (lighting cooling & HVAC)  CoGen LED lights (in some situations) Utility analysis software Co Gen 20
    21. 21. 4Understanding funding opportunities 21
    22. 22. NYSERDA CFA – Consolidated Funding Application – A single application that streamlines access to NYSERDA’s Grant program and possibly additional funding from other NYS agencies. Existing Facilities FlexTech CHIPS 2.0 – High efficiency school building standard for both new and retrofit building projects New opportunities in 2012 22
    23. 23. NYSEG/RGE & National Grid NYSEG/RGE  Existing Facilities - Small Business Energy Efficiency Program – Less than 100,000 kwh/month. < 70% materials & labor. National Grid  Existing Facilities – Lighting – < 50% materials & labor All utility delivery companies offer a Custom Measures Program 23
    24. 24. Energy Performance Contracting SED allows EPC agreements to go out a maximum of 18 years. 5 to 10 year EPC agreements are optimal Take advantage of SED $100,000.00 project incentive. C&S Companies of Syracuse has an innovative solution called “NET ZERO” that combines features of an EPC agreement with five $100,000.00 projects. Building aid + energy savings + grant money = $0.00 cost to district for over $500,000.00 worth of projects. Consider a “self-directed” EPC 24
    25. 25. 5Identifying low cost/no cost opportunities to reduce cost 25
    26. 26. 26
    27. 27. Operations & Maintenance  Functioning as designed  Calibrate thermostats  Adjust dampers  Janitorial services 27
    28. 28. Functioning as Designed Retro-commissioning Regularly inspect all equipment and controls to ensure they are functioning as designed 28
    29. 29. Functioning as Designed Example 1: New school building with regular power quality problems. Motors burning out, light fixtures failing early. Two years after construction, it was discovered that a power conditioner was installed as part of the original construction, but was never turned on. Example 2: Public school built around 1975 with pneumatic controls, with consistently high heating bills and increasingly more difficult to control temperature. Detailed physical inspection of unit ventilators revealed that in prior years as pneumatic controls failed, the outside air dampers where hardwired in the open position (either 100% or 75% open). 29
    30. 30. Calibrate Thermostats Periodically, walk through the building and compare the thermostat setting with a hand held digital thermometer (preferably with 2 decimal places) 30
    31. 31. Adjust Dampers  Bring in the least amount of outside air necessary to maintain proper air quality  Reduce outside air requirements by adjusting dampers to minimize the need to condition outside air (within codes) 31
    32. 32. Janitorial Best Practices  Team Cleaning  Day Cleaning  Coordinate Lighting  Occupancy Sensors1. Joe Serna Jr (office building. Instituted day cleaning with hours from 11am to 8pm during 2001 energy crisis. Savings of 8% Total Building Energy2.
