CHAPTER V


PAYMENT OPTIONS

Method Pro’s Con’s Comments

Cash no interestrequires immediate

capital fundsusually a budget item

3rd Party Lease no money downAcct. Dept. may label as capital

lease

provides positive cash flow; lease term longer

than payback period

Performance Contract no money down10-20 year

commitment; too expensive

financial vehicle of choice by ESCO’s

Shared Savings no money downextensive M&V required, too

expensive

takes advantage of uneducated client

Blend into Electric Bill no money downmust renew electric

contract

no capital request or approvals needed; can include other ECM’s

CHAPTER VI

RETROFIT TRENDS: TECHNOLOGY

•  Wireless Controls –  EnOcean vs Zigbee vs. Wi-Fi

–  Annual fees, still maturing

•  Linear Fluorescent –  Lamps: Energy-Saving, long-life, amalgam

–  Ballasts: HE, 480 volt, ILO

–  rare-earth phosphor shortage

•  LED –  Improved: manufacturer claims, LPW, luminaires

•  Induction –  Niche audience, LLD problem


RETROFIT TRENDS: TECHNOLOGY

•  Pulse-Start Metal Halide & Electronic Ballast kits

–  improved LLD, longer life

•  Ceramic Metal Halide kits –  great CRI, improved LLD, small footprint

•  Plasma –  still chasing LED

•  Compact Fluorescent –  sell your stock now...


RETROFIT TRENDS: APPLICATIONS

•  Parking Garages –  EPACT, daylight & occupancy control

opportunities

•  Exterior –  poles, building-mount, canopy

•  Hospitals –  24/7 hours, 1st generation T8, well-being of

patient

•  Refrigerated Warehouse –  perfect for LED!

•  Auto Dealerships –  see exterior above
