2005 In an attempt to combat growing energy problems, Congress passes The Energy Policy Act, providing tax incentives and loan guarantees for energy production of various types.
3 Areas - Lighting- Building Envelope- HVAC Maximum Deduction - $.60/ft2 ($1.80/ft2 total for all 3) Renovated Area Up to Total Material Cost
2 Methods to Qualify 1. Building-wide Energy Model - largest deduction, more complicated to certify2. Interim Lighting Method - simpler to calculate, better suited for lighting retrofits
Building-Wide Energy Model - ASHRAE/IESNA Standard 90.1- Requires software modeling of building energy usage
Compliance - ASHRAE/IESNA Standard 90.1
Interim Lighting Method - Out with the old…
Requirements - Consumption & Building Type
EPACT Deduction 40% - How do I qualify? >25% PRO-RATED
EPACT Deduction - How do I qualify?
Lighting Controls • ASHRAE 90.1 (2001) - Bi-Level Switching
Additional Savings Methods - Rebates/incentives through local power company- Fixed rebates or custom incentive packages
Utility Co. Incentives Restaurant & Grocery Audit Program - Free audit of refrigeration system - Incentives for: Automatic door closers LED case lighting Motion sensor on case lighting Night covers
Utility Co. Incentives Commercial & Industrial Incentives - Custom program, tailored to individual customers - Retrofit only, new construction does not qualify - Must save at least 100,000 kwh/yr - Rebate of $.05 per kwh saved
Utility Co. Incentives Commercial & Industrial Rebates - Administered by 3rd party (Energizing Indiana) for several utilities throughout the state—I&M, Duke, NIPSCO, & others - 3 Rebate areas: Lighting, HVAC, & Food Service Equip. Lighting - replace T12 or HID light fixtures - no LED rebates (yet) HVAC - min. efficiency of HVAC equipment, add VFDs to motors Food Service – Replace with energy star equipment • New construction qualifies for rebate • Baseline is minimum design that meets building & energy codes
Utility Co. Incentives Emergency Demand Respond Rider • Customer agrees to reduce demand at critical times and receives monthly payment from I&M • Minimum 250 kva reduction • Benefit for customers with generator backup • - $2.50/kw/month
Utility Co. Incentives HVAC Rooftop Tune-Up • Incentivesfor adding economizer, CO2 sensors, multi-stage cooling

Example - 200’x 200’ Warehouse- Existing 400 watt Metal Halide Hi-Bays @ 25’ O.C. 64 qty @ 456 watts/ea = 29,184 watts26.1 footcandles, .73 watts/sq ft.29,184 w @ 7.6¢/kwh @ 14 hrs/day = $31.05/day or $11,333.00/yr
Example - Replace 1 for 1 With 6-lamp T5HO Fluorescent Hi-Bays + Dual Level Switching + Instant On + Less Lumen Loss + Longer Lamp Life 64 qty @ 361 w/ea = 23,104 watts34.0 footcandles, .58 watts/sq ft.23,104 w @ 7.6¢/kwh @ 14 hrs/day = $22.67/day or $8,273.00/yr
$3,060/yr SAVINGS OF Example - Replace 1 for 1 with (6) T5HO Fluorescent Hi-Bays + Switching + Instant On + Lumen Loss + Lamp Life 64 qty @ 361 w/ea = 23,104 w & 34.0 f.c.23,104 w @ 7.6¢/kwh @ 14 hrs/day = $22.67/day or $8,273.00/yr
SAVINGS-24 hour operation savings $5,245/yr- Reducing the number of new fixtures to maintain current light levels leads to… @14 hrs/day $5,541/yr @24 hrs/day $9,500/yr
TAX SAVINGS/TOTAL COSTMaterial costs (assume in-house labor) -$11520Tax SavingsMax. Allowable – 40,000 ft2 × $.60 $24,000 Actual Cost $11,520 Allowable Deduction $11,520 Typical Corporate Tax Rate 30% Tax Savings $3,456 I&M Rebate $51/fixture x 64 $3,264 Total Initial Savings +$6,720TOTAL COST $4,800
PAYBACK 1 FOR 1 REPLACEMENT@ 14/day operation, payback = 1.6 yrs@ 24/day operation, payback = .9 yrs W/ EXISTING F.C. LEVELS(30% Fixture Qty Reduction)@ 14/day operation, payback = .6 yrs@ 24/day operation, payback = .4 yrs
