E2=P2 Add Energy Efficiency to your P2 Toolbox

2. Good Environmental Manangement = Good Business $ense • Energy Efficiency Improvements frequently have the highest return on investment possible (usually loan cash flow positive) • Don’t just pay electric bills, examine them for conservation opportunities

3. Demand Side Management • Reduced demand = lower electric bills • Business pay an additional surcharge on KW demand (15 min. peak/month) • Some utilities have off peak vs. peak demand pricing (switch big KW users to off peak) • Switch big KW users to alternative fuel (electric to gas hot water heater) • Peak Shaving for industrial users • Get rid of any electric baseboard heaters!

4. ENERGY USE - Lighting • Fluorescents – new Super T-8 electronic ballast fluorescents use 30+% less energy than older style fluorescent fixtures* • Compact Fluorescents* – last up to 10X longer than incandescent bulbs, use ~1/3 of the energy (not economical to use with dimmers). Lots of selection nowadays. * Flicker Checker: 800-MLI-0089

5. ENERGY USE - Lighting Exterior lighting: • Switch to motion sensors and/or Compact Fluorescent flood lights • Photocells run lights ~4300+ hours per year (twin 150 watt floods on photo uses ~$150+/yr) • Compact security type lights: 9-70 watts = 680-6400 lumens for <$25 each, uses $5-$36/yr. • Lots of selection nowadays! • Metal Halide & Sodium (replace & recycle Hg vapor lamps)

6. Energy Efficient Lighting • Recommend energy efficient lighting for lights left on for more than 6 hours/day. • T-5 High bay fluorescents (~225 watts/ea.) vs. 1000 watt Metal Halides The Sheraton Hotel in Burlington Saved: $13,610 in one year through energy efficient lighting upgrades.

7. ENERGY USE - Lighting • Many areas are over lighted • Use light meter to determine if area is over lighted (20-50 foot candles=office) • Use task lighting where appropriate • Retro-fit Exit signs (incandescent or fluorescent) with LED, uses 5.4 watts, lasts 10+ years! $15.00 www.efi.org. Replacement exit sign=$25+, uses 2 watts, lasts 25 years

8. ENERGY USE - Lighting Lighting Controls: • Motion sensors (in less used areas) • Occupancy sensors (adjust from default) • Dimmers (use what you need) • Rewiring ceiling fluorescent to switch to % of room coverage vs. halves • Timers – can switch use to off peak

9. Energy Use - General • Commercial Coffee makers’ heating elements run 24/7 even when turned off – place on timers • Insulate all basement hot water pipes, run water at 120-130 F max. • Replace worn door weather strip • Use pool insulation covers at night • Use ENERGY STAR equipment

10. Energy - Refrigeration • Why not use NE winter temperatures to cool product with an “Economiser”? • Older compressors, evaporators and fans can be far less efficient (>10+ yrs. old) • Are compressors well ventilated? Dust free? • Cooling empty space? Keep coolers/freezers full or downsize units • Replace hot walk-in incandescent light bulbs with cool compact fluorescent bulbs • Stand alone beverage coolers very inefficient

11. Energy – Heating/Cooling • Programmable set-back thermostats can save 10%+ for a 10F+ setback • Use Premium, high efficiency motors for >1 hp, 3 phase motor replacement (~2-3% more efficient than standard grade) • Variable speed drives on larger motor & circulation pumps
