2010 Recognition Award Winners
- Installed a heat exchanger/propylene glycol loop system to recover waste heat from a fryer stack. Enough heat is recovered to heat their entire 550,000 square foot facility for the winter plus handle 3 potable hot water loads, saving $600,000/year and reducing CO2 by 2,200 tons/year. The system is large enough to handle additional thermal loads that arise.
- Researching the addition of an adsorption chiller to the glycol loop system to use waste heat for meeting the plant’s cooling and air conditioning loads.
- Fleet changes included:
- Installed direct fire heaters on 55 trucks to reduce engine idling, which saved 4,000 gallons of fuel and over 38 tons of CO2 in 2010.
- Installed aerodynamic features to tractors and trailers, including fuel tank skirting which has a 4% MPG improvement saving over 12,000 gallons/year of fuel and 120 tons of CO2/year. Also converted from double to single axles in tractors, improving MPG by 14%.
- Converted 49 trucks to an 80% more fuel-efficient model. In 2010 this saved 26,000 gallons of fuel and reduced 250 tons of CO2.
- Switch to synthetic oil tripled the mileage between oil change intervals, improved fuel economy by 1%, led to better winter cold-starts and reduced waste oil by 2,400 gallons/year.
- Implemented driver training to teach eco-driving tactics such as proper shifting, speed control and idling reduction. This will save an estimated 8,900 gallons/year of fuel and 85 tons/year of CO2.
Milwaukee County Transit System (Milwaukee)
- Purchased 90 new buses that meet 2010 engine standards, reducing emissions by over 90%
- Replaced 20 older diesel engines with new engines, resulting in a 20% emission reduction and annual fuel and maintenance savings of over $200,000
- Buses feature engine, emission, brake and tire technologies that improve mileage

- Installed timers on their tool air compressors to prevent them from running continuously
- Installed a new boiler at one of their buildings that is 20% more efficient, saving over $7,000/yr
- Replaced electric baseboard heating with gas heat at administration building, which is expected to save over $75,000/year
- Implemented a company-wide energy savings policy for employees prohibiting use of personal space heaters, humidifiers and fans and requiring computers and lights to be shut off when not in use
- Created an Energy Team to monitor and minimize energy consumption
Roundy’s Supermarkets, Inc. (Milwaukee)
- Committed to ongoing voluntary reductions in energy, waste and emissions at their Oconomowoc Distribution Center via participation in WDNR’s Green Tier program.
- Achieved 2010 energy reductions of over 700,000 kWh and saved nearly 600 tons of CO2 at their headquarters though adjustments to the lighting schedule, use of self-adjusting light fixtures, using less bulbs per fixture, and shutting down computers during inactivity.
- Improvements at their distribution centers include:
- Retrofitted over 25% of its Oconomowoc trucks with diesel oxidation catalysts.
- Prohibit idling in its fleet and implemented strict limitations on third party trucks at two of their distribution centers.
- Use software tools to evaluate optimal trailer load to reduce mileage and fuel use.
- Promote carpooling with preferred parking, which has a participation rate of 125 employees.
- Replaced forklift battery chargers at the Stevens Point distribution center and installed controls to reduce load during non-charging periods, which saved over 130,000 kWh and 100 tons of CO2 in 2010.
- Upgraded 2,000 lighting fixtures and installed occupancy sensor controls which decreases energy and heat emitted, further reducing energy usage. Annual savings estimated at 750,000 kWh and 590 tons CO2 reduced.
- Recycling plastic, papers, and metals from its distribution centers and retail stores.
- Installation of 231 solar panels on one of their stores resulted in over 58,000 kWh savings (3% reduction) and 44 tons CO2 reduction in 2010. Examining installations at other stores.
