In 2012, UofL installed real-time energy-monitoring and display technology in four residence halls. These online Building Dashboards allow residents to get a handle on their energy usage and to get real-time feedback about conservation efforts within the residence halls!
Check out these new online portals, make a personal commitment to reduce, and gain a better understanding of your energy use:
UofL's annual utility bill (electric, gas, water and sewer) is over $19.5 million. In recent years, we've spent nearly $1 million every month of the year on energy ($11.7 million for electricity and gas in 2011). There are tremendous cost savings and environmental benefits to be gained from using energy and water more efficiently on campus.
You can help us identify opportunities to save! If you notice problems in UofL buildings such as leaky plumbing fixtures, rooms that are excessively heated or air conditioned, windows that won't shut, lights which won't shut off, etc. take a moment to report the problem online here or call it in: Belknap Campus: (502) 852-6241 Health Sciences Center: (502) 852-5695 Shelby Campus: (502) 852-5601
UofL has made massive investments to retrofit its existing facilities in order to increase the efficiency of our operations, reduce costs, consume less energy and water, and produce less pollution as a result.
This $46.2 million project, involving 88 buildings (6.2 million square feet) on all three UofL campuses will directly save the university $4.4 million every year and reduce our annual carbon dioxide emissions alone by over 46,000 tons (the equivalent of removing 7,690 cars from the road).
With these improvements, UofL expects to reduce its utility bill by about $12,086 per day!
These efforts have already produced documented results. In FY 2011-12, Belknap Campus reduced fuel use 48%, electricity use 27%, and water use 31%. Efficiency-minded campus users helped us exceed our engineers' expectations! They had predicted fuel use
to decline nearly 40% and electricity use to drop at least 20% annually.
Some examples of efficient lighting and insulation jackets installed at UofL.
Low-flow shower head replacements were installed throughout Belknap campus in 2010.
Examples of efficiency retrofits include:
Efficient lighting: Installed 117,483 fluorescent lamps, 41,714 ballasts, and 1,729 exterior induction lamps. Reduce lighting energy consumption by 14% for an annual savings of over $915,000.
Insulated steam valve jackets: 1,152 installed. Reduce heat loss at the valve by 90%. Saves over $327,000/year.
Occupancy sensors for lighting: Installed 2,011 occupancy sensors to automatically shut off lights in vacant rooms. Reduces lighting energy consumption by 20-40%, saving over $97,000/year.
Low-flow shower heads: 616 standard shower heads were replaced
with efficient 2.0 gallon/minute heads. Reduces water use by an average
of 11%, saving over $34,000/year.
Low-flow faucet aerators: Installed 20,426 pressure independent aerators. Reduces water consumption at sinks by an average of 58% for an annual savings of over $159,000.
Efficient motors: Replaced 259 motors with new models that use an average of 5% less energy for an annual savings of over $35,000.
Energy efficient belts for motors: Replaced 213 standard V-style belts with non-slipping synchronous belts with variable frequency drives. Cuts energy use by an average of 8% for a savings of over $46,000/year.
History of the Project: In October 2009, UofL and Siemens Building Technologies Inc. began work on a $21.7 million, 13½-year performance contract to increase efficiency on Belknap Campus. In 2010, a second phase performance contract was finalized for the Health Sciences Center, Shelby campus, and a few more Belknap projects, involving another $24.5 million in retrofits.
ecoScorecard can be used to compare the green attributes of products from furniture to flooring and see how each contributes to LEED and other certifications.
All new construction and major renovation projects at UofL are designed and built in accordance with Kentucky's High Performance Building Standards, using the Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ as a guide or for certification, depending on the scale of the project. LEED standards not only encourage efficiency, but a wide range of practices which reduce the total environmental impact of buildings during construction and occupancy.
UofL is currently in the certification process for what we expect will be our next LEED Gold certified building - the new Student Recreation Center on 4th Street. The SRC opened on Belknap Campus in October 2013, and was designed to achieve LEED Gold certification. It features UofL's first geothermal system (see below).
As we transition toward climate neutrality by 2050, UofL has made a bold commitment to renewable energy. Our
immediate goal is to source at least 20% of our power from renewable
energy sources by 2020. UofL is seriously exploring options including solar, biomass, geothermal, and low-impact
hydropower projects. Some of these efforts are tied to
educational and research objectives at UofL. More details are available in UofL's Climate Action Plan.
In 2009, UofL commissioned consultants from Cannon Design to produce
a report on the practical and economic feasibility of renewable energy
options for UofL, including solar, wind, geothermal, hydropower,
biomass, and landfill gas. Download a copy of the report here.
the moment, UofL, like most utility customers in Kentucky, still relies
largely on fossil fuel-generated power purchased from the grid. We do
not currently generate a significant percentage of our electricity on
campus, but we are moving in that direction with a commitment to
renewable energy that has already manifest itself in a number of pilot
Renewable Energy & Energy Efficiency Club members Josh Wilcox, Ezra Clark, Sam Ellis, Alejandro Martinez, Jason Absher and Harry Russell install solar panels for Garden Commons greenhouse.
UofL's latest project featuring renewable energy opened in October 2013. The new Student Recreation Center on 4th Street features not only a solar hot water system, but 128,000 square feet of space heated and cooled by the University's first geothermal
system. The geothermal heat pipe is a closed-loop vertical well
system with a total of 180 wells 400 feet deep. This system provides
ample reserve capacity and is expected to generate about 22% annual
energy cost savings compared to a conventional system. It is also considerably simpler and cheaper to maintain. Read more.
In October 2013, UofL students took part in the U.S. Department of Energy's Solar Decathlon competition, finishing first in the Affordability and Power categories!Read more about the experience.See the full results here. UofL students, faculty and staff collaborated with others from Ball State University and the University of Kentucky as "Team Kentuckiana" to design and build a fully solar-powered, modular home called "The Phoenix House." The project was designed to aid in disaster recovery and provide a model of green living! The home will be reinstalled on the UofL campus for further research and educational purposes. For more information, contact the team's faculty mentor, Dr. Mark McGinley (502-852-4068). To contribute, contact Jason Diffenderfer at 502-852-1248.
The roof of UofL's LEED Gold certified Center for Predictive Medicine on the Shelby campus houses a 50 kilowatt solar photovoltaic array, one of the largest in Kentucky, with 254 panels (see photo above).
The computer controlled dual-axis tracking solar array on Sackett Hall at the J.B. Speed School of Engineering produces both electricity and hot water for the building. It is the only such tracking array in Kentucky, and is intended for research, development and
education, while supplying a portion of the building's electricity and hot
water. Because it is able to track the sun precisely throughout the day and across the seasons, it is 30% more efficient than fixed solar panels. The two solar thermal collectors in the center of the array provide nearly 100% of the building's hot water in the summer, and ten photovoltaic panels feed enough electricity into the grid to power the building's computer laboratory. Check out how much energy the system is capturing right now!
We are investigating renewable energy options to passively heat & cool UofL buildings. At Burhans Hall on our Shelby campus, in collaboration with the Department of Energy and the Kentucky Renewable Energy Consortium, UofL's Renewable Energy Applications Laboratory (REAL) installed an experimental solar heat pipe wall for indoor climate control that may prove to be twice as efficient as other solar systems in places such as Louisville with moderate sun and cold winters. In 2011, the system was moved to a new solar test room constructed at the Speed School of Engineering behind Ernst Hall for further experimentation and monitoring. This is the only such device of its kind in the world and its active solar design is more efficient than most passive systems.
Since 2009, Chemical Engineering faculty and students have been involved in the conversion of waste vegetable oil from UofL Dining services into biodiesel used to fuel our campus shuttle. We began to scale-up this effort in 2011, when UofL Dining began supplying used cooking oil for local conversion into biodiesel. The project began through a partnership with the Louisville Biodiesel Cooperative and now Kelley Green Biofuel of Goshen, KY (5100 Greenhaven Lane), a community-scale, ASTM-certified, National Biodiesel Board registered biodiesel producer with an annual capacity of 75,000 gallons, located just 30 miles from campus. Check out the details of the project here.

In 2013, UofL launched a new Space Heater Policy, designed to discourage the use of inefficient personal space heaters in rooms on campus where central heating and air conditioning can be adjusted to fix the problem.
Space heaters are expensive energy hogs and can pose serious fire and electrical hazards. UofL strongly
discourages their use in offices and bans their use in residence halls, Greek housing, or any sleeping quareters.
The University shall strive to maintain room temperatures as follows: During Heating Season: Occupied Hours 66-72 Degrees F. Unoccupied Hours 55-65 Degrees F. During Cooling Season: Occupied Hours 74-78 Degrees F. Unoccupied Hours 78-85 Degrees F.
If your room is cold, please contact Work Control
to request a room temperature audit and adjustment. Either fill out a request online here, or call 852-6241 (Belknap); 852-5695 (HSC); or 852-5601 (Shelby).
Temporary use of
an approved space heater may be allowed only if sub-66 F temperatures
persist following a Physical Plant audit and adjustment.
Preferred heaters use radiant heat (rather than resistant heaters whose coils may exceed 1000 degrees F), and are thermostatically-controlled. Radiant heaters are more energy efficient because they are designed to radiate direct heat to the users’ body.
If using university funds to purchase a space heater, University policy requires that such purchase is made through the UofL Stockroom. The purchase of space heaters through retail establishments using University funds is not authorized nor will those charges be approved for reimbursement. Using a University credit card for the purchase of space heaters is also in violation of University policy since these items are available through the UofL Stockroom (333 E. Brandeis Street, 852-6253).
Vegetated roofs are not only beautiful, but they help moderate temperatures to reduce the urban heat island effect and building energy demands for cooling and heating, while reducing storm water runoff, generating oxygen, and providing wildlife habitat in the urban landscape. They can also be designed as green spaces for urban dwellers looking to escape the concrete jungle.
The University of Louisville has begun installing green roofs to help demonstrate their many benefits, with projects at the new College of Business expansion, the Early Learning Center at Family Scholar House, and the new Cardinal Towne affiliated student housing and retail facility.
In July, 2012, UofL officials gathered for a ceremonial planting of the new green roof sprouting on the first building at the new Nucleus Innovation Park-Market Street,
a subsidiary of the UofL Foundation. The eight-story,
200,000-square-foot, LEED building is expected to open in May 2013 and
Bernheim Forest nursery specialists are advising building contractors
how to design and maintain the roof, which will feature Kentucky native
In June 2012, UofL dedicated a new wing at Harry Frazier Hall, the College of Business building. The wing houses the equine and entrepreneurship programs. The roof of the building is a vegetated green roof called the M. Krista Loyd Sky Garden, named for the daughter of Raymond and Eleanor Lloyd of Louisville. The garden will reduce storm water surges and is expected to trim heating and cooling costs by 25% in the two-story addition it covers.
Besides the roof, other green features of the new wing include: - 97% of all occupied spaces have natural day lighting; 94% have a direct line of sight to the outside. - Radiant heat panels along the window wall keep the rooms evenly heated. - Low-E glass reduces heat buildup in the summer and reflects heat back in the winter. - Low VOC-emitting paint, sealant, adhesives and flooring reduce indoor air contaminants.
In 2013, UofL competed nationally and locally in the Bluegrass Unplugged competition against UK, WKU, and Berea to reduce electricity use in residence halls during the Campus Conservation Nationals.CCN is the largest nationwide electricity and water reduction
competition on 200 college and university campuses, covering 2500
buildings and 250,000 students!
From March 23 - April 12, 2013, UofL
residents competed to achieve the greatest possible energy reductions in thirteen
residence halls. Results are below. Click on the links to see electricity consumption patterns in each hall:
Prizes were awarded to the UofL residence hall which reduced the most! Residents of Bettie Johnson earned the Grand Prize: a Skate Party at Skate World April 18th 7-10pm! After each week of the competition, residents in the leading hall were be able to pick up free UofL Sustainability reusable shoulder bags, mugs, and water bottles in their lobby!
As the Kentucky school with the greatest average reduction, Western Kentucky University took home the Bluegrass Unpluggedtrophy!
In 2012, 100 colleges & universities across North America engaged over 200,000 residents to save 1.7 gigawatt-hours of electricity! This equates to taking 151 U.S. homes off the grid for a year, $158,000 in savings, and 2.6 million pounds of carbon dioxide emissions averted!
From March 26 - April 15, 2012 UofL residents were able to reduce energy consumption 11.9%, saving 38,415 kWh of electricity! This equates to $2,689 in savings, and 78,789 pounds of carbon dioxide averted!
