The harsh winters of the upper Great Plains hold no fear for the University of North Dakota, Grand Forks, first in its division in hockey and first among educational facilities to receive Western's Administrator's Award for customers with superior achievements in energy efficiency or renewable energy.

Representatives from Western's Upper Great Plains regional office braved eight inches of snow Dec. 15 to honor UND and tour some of the campus projects that helped earn the award. UGP Regional Manager Robert Harris praised the university's staff for its top-down commitment to providing a safe, quality, energy-efficient learning environment. "It's a great example of what one customer can do to further the country's goals of energy independence and a cleaner environment," he said.

Successful program evolves from cost-saving efforts
Western provides more than 60 percent of UND's electrical energy requirements. UND is a coeducational, state-supported institution with an enrollment of more than 12,000 students. The campus facilities department maintains 239 buildings covering more than six million square feet.

The Administrator's Award recognizes the success of UND's campuswide energy efficiency program, the innovative program funding and the energy management team carrying out the program. UND designed the program to affect every facet of campus energy use, including electric, gas, oil, steam, water and sewer systems. "When we first started back in the ‘70s, we were really the only kids on the block doing energy efficiency," said Facilities Director Larry Zitzow. "The program has evolved through decades of research and experiments into something the entire university is very proud of."

There were two reasons the university entered the largely uncharted territory of facilities energy management in those days, Zitzow recalled: "Money and manpower, which actually comes down to the same thing," he said. "Hooking a few buildings up to early building automation software allowed us to reduce the workforce, because we no longer needed a person in every building to tell us what was happening."

Equipment loan and corporate partnership supply new technologies
Honeywell supplied the first automated monitoring systems through a partnership with UND. "Initially, we didn't have a lot of funding for our energy management program, so the university applied to become a research and development site for Honeywell," explained Technology Advancement Coordinator Randal Bohlman. "We've helped them develop new products, and our buildings have been alpha and beta test sites for software programs."

Currently, 108 campus facilities are equipped with state-of-the-art automated systems that monitor, adjust and report on building energy use. The results are award winning, to understate the case. In 1980, facilities department records show that at peak load, the steam plant pumped 247,000 pounds per hour to heat 3.1 million square feet. Today, the square footage of campus buildings connected to the steam plant has more than doubled, while the system's peak load has not gone over 220,000 pounds per hour in the last three years. "That's kind of a Cinderella story for a facilities department," said Bohlman, who has been instrumental in the energy program's success.

Western's Energy Services equipment loan program also contributes to the university's energy savings and electric system reliability. The facilities department borrows infrared cameras to perform regular scans of the campus electrical system, both above and below ground. Scanning, along with frequent quality tests on transformer fluid, identify potential problems, allowing for scheduled maintenance shutdowns. Scheduling is critical to a research institute like UND, said Zitzow. "Nobody likes to lose power in their lab or classroom, but they can plan around a scheduled outage," he said. "If a research lab experiences an unexpected power loss, it can destroy thousands of dollars worth of work."

Bond money finances additional energy saving projects
Borrowing diagnostic equipment and partnering with product designers helps to contain costs, but like any other effective program, energy efficiency needs a funding source. UND uses bond funds the 2002 North Dakota legislators established for institutions to plan and implement energy-saving projects. Institutions borrowed money from the fund for projects that would repay the loan through savings on utility bills. "Projects that demonstrated prompt payback got the funding," Zitzow said.

The state awarded the university $3.9 million of that bond under its Facility Energy Improvement Program. Zitzow attributed the large award to UND's documented energy management success and having the technology and experienced staff needed to carry out the projects. The award financed 11 projects that have generated an additional $640,000 in yearly energy savings, providing a simple payback of 6.2 years.

One recently completed project involved heating a building by capturing the kinetic energy from computer systems, lighting and even building occupants. The automation system determines where and when heat is needed and circulates it through the existing air ducts. The 60-horsepower motor that drove the building's fan has been replaced by a 40-horsepower motor that circulates one-third more air using only 50 percent of its capacity. "We reduced heat demand 60 to 80 percent by using the automation system to its fullest extent. I haven't seen a heat valve open all winter," said Bohlman, who designed the project.

Dedicated staff position continues to improve energy management plan
As technical advancement coordinator, Bohlman is the energy efficiency program's secret weapon. Trained in industrial engineering, he joined the facilities department in 1975 as an electronics technician. His job evolved over the years as he applied his understanding of building controls to energy-saving strategies. "Every campus wishes it had somebody like Randy," Zitzow observed. "The state doesn't really have a classification for what he does."

In simple terms, Bohlman makes sure the university gets the most from its energy management technology. Collecting data on all the factors that affect energy use, consulting with engineering experts and developing computer models are all part of Bohlman's work.

Western is not the first Federal agency to recognize UND for its innovative efforts to lower its energy consumption system-wide. In 1994, Secretary of Energy Hazel O'Leary honored the university for measures that reduced its steam plant's fuel use by 6.5 percent, with a payback of less than five years.

Having become the first educational institute to receive Western's Administrator's Award, UND has set its sights on becoming an Energy Star education partner. "We're just plowing the ground to see what it leads to," Zitzow said.

Considering the UND facilities department's knack for turning challenge into opportunity, it will probably lead to more energy savings.
