11 11 Lighting Where do we use our Energy? 40-65% of electric HVAC Systems 20-35% of electric 85-95% of natural gas Computers, Printers, Labs & Miscellaneous 10 20% of electric 5 15% of natural gas

12 12 Full Comprehensive Energy Audit ASHRAE I or ASHRAE II Paid for by the Utilities Utility Funded Energy Audits Provides a roadmap of potential energy savings opportunities Additional Efficient Products for Business rebates available for lighting, motors, VFDs, and Process Efficiency Rebates

13 13 Where to Start to Identify No-Cost Opportunities? Facility Energy Audit Identify potential energy savings opportunities No-Cost Low-Cost Capital Cost Develop a Plan of Action Immediate implementation 2-5 Year Plan Long-term Plan

14 14 No-Cost Opportunities Create an Energy Management Plan Change behaviors and establish expectations Educate Track Utility Usage YOU CAN NOT MANAGE WHAT YOU DON T TRACK Establish an Energy Management Plan Incorporate Green Teams 8-10% Savings Establish Temperature Set-Points Establish Energy Goals Personal Appliances Policy Incentive Programs Green Suggestions Program Energy Waste Patrol Program

15 15 Lighting Opportunities No-Cost Opportunities De-lamp hallways and often unoccupied areas Turn-off lights or leave them off longer Custodians cleaning behavior Facility managers morning start-up procedures Parking lot lighting operation Old lights burn out, replace with more efficient lights LED Screw-ins LED Tubes Don t replace metal halide bulbs (retrofit with LED)

16 16 HVAC Systems Opportunities No-Cost Opportunities Temperature set-points 68 for heating and for cooling Lower domestic hot water temperature Scheduling of facilities Use existing controls (more zones) 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

17 17 Low-Cost Opportunities Lighting Opportunities De-lamp hallways and office spaces typically over lit Install reflector kits and increase the lumen lamps you are using (5000K rather than 3200K or 4100K) Typically 2 lamps in hallways and 3 lamps in office space 1-4 year payback Occupancy Sensors Automatically shuts off lights when the area is not occupied Don t install everywhere 2-5 year payback

18 18 Low-Cost Opportunities Lighting Opportunities Vending Misers Reduces light and compressor cycles 1 year payback (50% ROI) Exit Signs to LED 24/7 operation 1 year payback (50% ROI) Plumbing & Insulation Replace leaking faucets, sinks, toilets Fill and dump toilets Low-flow faucets & toilets Repair leaking pipes and valves Retrofit steam traps and steam leaks Insulate HW and Steam Pipes/Tanks/Valves, etc.

19 19 Kitchen Enhancements Walk-in cooler/freezer controls Reduces compressor cycles based on food temperature 2-3 year payback Kitchen Exhaust Hood Ventilation Controls VFD on exhaust fan Based on dirtiness of the air 6-9 year payback Building Envelope Sealing Caulking Weather stripping Air flow adjustments 2-7 year payback Low-Cost Opportunities

20 20 Low-Cost Opportunities HVAC Systems Opportunities Better Control of Building Occupancy Timers for Schedules (no DDC) Boilers, pumps, motors, etc. Use Direct Digital Controls for: Optimum start/stop CO2 demand ventilation Coil cleaning on chillers & Insulation of pipes Water treatment System will operate more efficiently Equipment will last longer Less leaks and valve issues Work Order System (CMMS System)

21 21 Lighting Opportunities Interior & Exterior LED Retrofits watt lamps to 12 watt 5-7 year payback Health Provides steady natural full-spectrum lighting Eliminates flicker vertigo Improved Safety Interior and Exterior Illuminates dim spaces Contains no mercury or lead Productivity Mid-Range Cost Opportunities Increased motivation improves alertness and mood Environmental Lower Energy consumption Significant Maintenance Savings (25 Year Life Expectancy)

22 22 Capital Cost Opportunities HVAC Systems Opportunities Equipment Replacements Boilers, chillers, rooftop units Variable Frequency Drives Motors 2-5 year payback Building Automation Systems Replace pneumatics (air) to DDC (direct digital controls)

23 23 Building Envelope Capital Cost Opportunities Doors & Windows Replace with high efficient doors and windows year payback Roofs Replace or repair Wet insulation 7-25 year payback

24 24 How do we implement Capital Cost Projects and NOT affect our Budgets? BEFORE FACILITY ENHANCEMENTS AFTER Lighting Controls $27,466 Extra Money in the Customer s Pocket Energy Expense Endocubes Water Enhancements $32,581 Average Annual Project Payment $198,450 $138,404 Reduced Average Annual Operating Expense *Average Annual Payment and Expenses are based on 20 Year Average

25 Funding Mechanisms Energy Savings Service Agreement 25 Energy Savings Service Agreement (ESSA), Project Payments Turn-key energy savings project Requires no upfront capital Let your Energy Savings pay for the project PACE Financing Property Assessed Clean Energy Program PACE programs allow a property owner to finance the upfront cost of energy or other eligible improvements on a property and then pay the costs back over time through a voluntary assessment. Efficient Financing for Business Offered by AEP Ohio Capital Leases, PACE, Tax Exempt Municipal Financing, Energy Service Agreement From $1,000 to Multi-million dollar deals
