What If...
• Of 130 million American workers, less
than 1% walk (or bike) to work.
• Average round trip takes (1) gallon of
fuel.
...Then
• 3getting
million barrels of oil would be needed
to and from work every day.
What If...
• 25% of
American workers walked to
work.
• Average round trip takes 25% less fuel
because more people use public transit.
...Then
• 1.32
million barrels of oil would be
saved getting to and from work every
day.
How
• Better city planning.
• Less emphasis on the automobile.
• Revamp the “regional” model.
• Reestablish localism & mixed use.
• Influence by example.
On to lighting...
Industrial Lighting
Charlie Glab - Morrison Bros Co

History
Industrial Revolution
Lighting was poor.
Daylighting - 1890’s
Structural framing allowed larger expanses
of glass. Better light but limitations with
daytime & solar orientation.
Energy crisis -1970’s
Replace older glass systems with solid
walls. Heating cost savings outweighed
savings with daylighting.
More Recent History
Less glass - Plant Managers responded to energy crisis.
They filled-in, insulated, and lit up spaces with electricity.
Early electric lighting - Less expensive to operate
but still not the best lighting.
Investment in technology - Manufacturers
invested in new designs - efficiency & quality improved.
Today and Beyond
Daylighting
revival - mixed with
advanced lighting systems to
achieve top performance.
Specialized - glass
technology, fixture design,
high efficiency lamps, and
computer simulation.
Future - more
daylighting, better technology,
solar storage, greater
simulation & modeling tools.
Morrison Bros Co
Established in 1855
Fuel lamps 1800‘s & the glass box (1890’s).
•
First electric systems (1900‘s).
•
Remodeling and window replacement (1960‘s & 70’s).
•
•
Early modern electric grid (1990’s).
•
Advanced low energy system (2010).
The
objective
- better light at lower cost.
efficiency comes directly from the user.
The demand for
Sustainability (?) - The market drives investment for
technology. Sustainability - not new to those who manage costs.
Industrial lighting has been on a “green” track for 150 years.
Lighting Replacement Project
Facilities built in the 1990’s
400 watt high pressure sodium.
400 watt metal halide & 250 watt metal halide.
2010 Replacement
electronic ballast lighting.
More evenly dispersed light- less shadow.
Closer to daylight - tone and brightness.
50% energy savings.
DUBUQUE PLANT - HIGH BAY SPACE - METAL HALIDE LIGHTING
DUBUQUE PLANT - LOW BAY SPACE - METAL HALIDE AND OLD STYLE
FLUORESCENT LIGHTING
ASSEMBLY AREA - ELECTRONIC BALLAST LIGHTING
WAREHOUSE (2010) - ELECTRONIC BALLAST LIGHTING
TECH CENTER (2010) - ELECTRONIC BALLAST AND DAYLIGHTING
Cost/Benefit - Maquoketa Plant
High bay space - 35,000 square feet
Existing - (100) 400 W high pressure sodium units installed in 1990’s.
Replacement - (100) electronic ballast style (Cooper 6 with T-8 lamp).
Cost $16,500 + labor.
Rebate (Wisconsin Public Power Inc) = $6000.
Total net cost = $14,500.
Energy savings = $6000/year --- (2+ year payback).
10 year savings = $45,500.
Cost/Benefit - Dubuque Plant
High bay space - 24,000 sq. ft. Low Bay Space - 3500 sq. ft.
Existing - (54) 400 W & (18) 250 W Metal Halide units installed in 1990’s.
Replacement - (80) electronic ballast style (Cooper 6 with T-8 lamp).
Cost $12,000 + labor.
Rebate (Alliant Energy) = $1840.
Total net cost = $14,160.
Energy savings = $5220/year --- (less than 3 payback).
10 year savings = $38,060.
