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
demand side management
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!
energy use lighting
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

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)
energy efficient lighting
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.

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

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
energy use general
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
energy refrigeration
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
energy heating cooling
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
