ENERGY FACT: THE AVERAGE NEW REFRIGERATOR USES ABOUT 25% OF THE
ENERGY OF A REFRIGERATOR 40 YEARS AGO. IT IS ALSO LARGER, HAS MORE FEATURES, AND COSTS LESS THAN HALF THE PRICE, ACCORDING TO A 2011 STUDY.
Recognized for its participation
in the DOE’s Better Buildings
Challenge, the University of
Utah has reduced the energy use of a
historic campus building by 40%. The
42-year-old Dumke Health Professions
Education Building was selected as the
state’s first Better Buildings Showcase
project because of its historical sig-
nificance, continued importance to the
university, and the inefficiencies in its
obsolete heating and cooling systems.
Complicating the retrofit plan was
the fact that almost half of the building
space is taken up by high energy use labs
and walk-in refrigerators, with the rest
functioning as classrooms, offices, and
To remedy this issue, the university
focused on replacing antiquated or faulty
DDC controls, upgrading two boilers to
high efficiency models, and implementing the use of premium efficiency motors
and variable frequency drives for relief
fans, air handlers, and pumps.
Cumulatively, the facility upgrades
were able to reduce energy consumption

by 195 kBtu per square foot for an estimated savings of $57,000 per year, which
will be invested in future efficiency
upgrades through the university’s Energy
With the upgrades completed, the build-
ing is on track to meet its energy efficiency
goals and help Utah reach its campus-wide
goals of reducing energy use by 20% and
carbon emissions by 25% over 14 million
square feet of building space by 2020.
“The university’s efforts showcase
strategies that can be replicated at similar buildings, institutions, and facilities
across America,” says Dave Danielson,
assistant secretary for energy efficiency
and renewable energy for the DOE.
