2 Energy Optimizers, USA Brian Abels, Mechanical and Energy Engineer Energy Efficiency Auditing and Energy Systems Modeling 3-years as an Industrial Consultant for the Department of Energy Experience in K-12 Facilities Consulting Renewable Energy Systems Energy Conservation (H.B.264) Energy Efficiency & Education Programs HVAC Systems, Controls Lighting Systems and Controls 2

3 Agenda - Developing a Plan Why is it important? Where do we stand? Where is our energy going? What are our opportunities? Immediate Steps Short Term Long Term What are our priorities? No Cost Low Cost Capital Investments Is There Funding to Help? 3

4 Why is it important? 4

5 84% Of World Energy From Fossil Fuels Source: Kissock, 2011 In U.S. 86% from non-renewable fossil fuels Source: U.S. D.O.E. Annual Energy Review 2005

6 Rice on a Chessboard Story At 10 grains/in 2 = 2x Earth s Surface Area (Oceans Included) 6

7 Why Energy Efficiency? Source: Kissock,

8 World Energy Use Our Challenge: Sustainable Prosperity Successful Stewardship Today Source: Kissock, 2011

9 Where Does My Facility Stand? 9

10 kbtu/square Foot Allows different sized facilities to be compared apples to apples Essentially: Energy Size Or: Your building s Miles/Gallon 10

11 Example Facilities Facility Facility Name Annual Electricity Cost Annual Natural Gas Cost Total Annual Cost Total Usage kbtu/sq.ft. $ 73,726 $ 31,692 $ 105, Average (Education) = 81.6 Average (Worship) = Elec = 27.0 Fuel = 54.6 Elec = 14.7 Fuel =

12 Calculating Your kbtu/square Foot 1 Year of Utility Data Electricity: Billed in kwh x = kbtu Divide by Facility Size (ft 2 ) Fuel: Billed in MMBtu / 1,000 = kbtu Sometimes some companies bill in ccf or therms 1 mmbtu = 10 therms or ccf Divide by Facility Size (ft 2 ) 12

13 Where Does My Energy Go? 13

15 Typical Energy Consumption Source: 2003 CBECS Survey 15

16 What Can I Do? 16

17 No/Low Cost Opportunities Create a Facility Management Plan Change behaviors and establish expectations Establish a Facility Energy Management Plan Start a Green Team Establish Energy Goals Establish Temperature Set-Points Educate the Faith Community Develop & Implement Community Ideas: Start a Community Garden Rain Barrels for Landscaping Support a CSA Develop Environmental Events 17

18 No/Low-Cost Opportunities Lighting Opportunities De-lamp hallways and often unoccupied areas Tipp City Schools example Turn off lights or leave them off longer Custodians cleaning behavior Morning start-up procedures Parking lot lighting operation Old lights burn out, replace with more efficient lights CFL s Low wattage fluorescents Don t replace metal halide bulbs (retrofit with fluorescent) 18

19 No/Low-Cost Opportunities Review Utility Bills Billing errors are more common than you may think Springfield Schools demand error Review utility rate options Primary vs. Secondary (only some larger facilities) Utility providers Generation Transportation 19

20 No/Low-Cost Opportunities HVAC Systems Opportunities Temperature set-points 68 for heating and for cooling Lower domestic hot water temperature Scheduling of facilities Use new or existing controls (programmable thermostats) Schedule of domestic hot water pumps Preventative Maintenance Proper preventative maintenance will increase the efficiency of your HVAC system by 20-40% 100,000 sq. ft. building = $6,000 to $12,000 per year 20

21 No/Low-Cost Opportunities Vending Machine Misers (Less than $300 installed) 21

22 Low-Cost Opportunities Facility Energy Audit Identify potential energy savings opportunities No-Cost Low-Cost Capital Cost Help Develop a Plan of Action Immediate implementation 2-5 Year Plan Long-term Plan 22

23 Capital HVAC Opportunities Building Automation / Controls Temperature Set-points Each degree = nearly 1% savings Scheduling Ideal for Routine and Low Occupancy Facilities Special Events Optimum Start/Stop Zoning Based on occupancy and schedules 23

24 Capital HVAC Opportunities Building Automation / Controls (continued) Hot Water Re-set Domestic Hot Water Pump Control Demand Limiting Demand Response 24

25 Capital Lighting Opportunities Re-lamp existing lights with low-watt lamps De-lamp existing fixtures Retrofit existing fixtures Hi-Bay MH to Fluorescent (Community Centers/Gyms) Lighting controls & Misc. Occupancy sensors Daylight harvesting Scheduling Exit Signs (LED) 25

26 Worship Lighting Floods & Spots Common lighting technique in houses of worship Each situation is different, however: Non-Ballasted Fixtures Dimming Controls? No Typically replace with CFL or LED Cost vs Savings & Maintenance Yes Same: however, many dimmable CFLs do not work with older dimmers Ballasted Fixtures (HID) Replace entire fixture OR Retrofit fixture to bypass ballast 26

27 Miscellaneous Air Distribution Systems (Based on Size) Outside Air Control (CO 2 Demand Ventilation) Variable Frequency Drives 27

28 Renewable Energy Systems Wind & Solar Opportunities Stand alone payback (no grants or subsidies) year simple payback There are tax incentives Power Purchase Agreements Third party finances, owns, operates, maintains, warranties and insures 7-20 year agreement Facility owner purchases the power the system generates (reduced rate as compared to utility rate) 28

29 EO s Budgetary Audit Confirm utility costs and usages Analyze kbtu/square foot - compare Assess current levels and patterns of energy use; Identify low-cost operational opportunities to reduce energy consumption and costs; Identify capital project opportunities that would reduce energy consumption and costs. 29
