Energy Conservation
Process Improved
When the University of Minnesota committed to reducing annual campus energy usage five percent
by the end of 2010, the Facilities Management department (FM) knew a campus-wide effort
would be required. They mounted a three-pronged plan for reducing energy consumption that
included the following initiatives:
Recommissioning: FM’s Energy Management group has begun
an aggressive project to recommission (or tune-up) the energy
control systems in 40 buildings per year. More than $2 million in
savings have been implemented thus far, with another $2.4 million
in savings identified.
It All Adds Up Campaign: The U’s energy conservation campaign
enlists the campus community’s help in lowering energy consumption
by taking an Energy Conservation Pledge. It All Adds Up collected
more than 10,000 energy pledges by the end of fall semester.
Energy Conservation Operations (ECO) Team: A cross-functional
team created to operationalize conservation ideas, the ECO Team
rolled-out their first initiative in 2009 -- a green computing pilot that
could save the University $40 per machine annually.
People Who Use the Process
All units and individuals can participate by taking
the energy pledge and bringing their conservation
ideas to the attention of Energy Management or
the ECO Team. It All Adds Up!

Success Stories
Variety Club Research Center Building Controls Upgrade
Savings: $60,000/year, 711 tons CO 2
Emissions/year
FM replaced an outdated Heating, Ventilating and Air Conditioning (HVAC)
control system with a modern Direct Digital Control (DDC) system. This
allowed energy engineers to efficiently schedule HVAC system operation.
The systems had been running 24/7, or 168 hours per week in both laboratory
and office spaces. The new schedule lowered office space service by more
than 90 hours per week.
Ford Hall HVAC Variable Frequency Drive Installation
Savings: $24,000/year, 284 tons CO 2
Emissions/year
Engineers installed variable frequency drives on Ford Hall’s large HVAC supply
fans. Before recommissioning, the fans could only be operated at full speed,
regardless of how much air was needed. Occupancy sensors were installed
throughout the building, so that ventilation registers open only when rooms
are occupied and require heating or air-conditioning. Recommissioning has
reduced energy consumption in Ford Hall by approximately 15 percent.
Humphrey Center Lighting Efficiency Upgrade
Savings: $21,000/year, 249 tons CO 2
Emissions/year
After HVAC, interior lighting is the largest energy consuming system on
campus. FM completed a lighting retrofit project in the Humphrey Center,
replacing more than two hundred 110-watt mercury vapor lights with energy
efficient, 12-watt LED lights.
