Option 2: Non-electric renewable energy generated on-site 31835.64 MMBtu
Option 3: Clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes 0 MMBtu
Option 4: Purchased third-party certified RECs and similar renewable energy products (including renewable electricity purchased through a certified green power purchasing option) 0 MMBtu

A brief description of on-site renewable electricity generating devices :

1. 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.
2. Sackett Hall Solar Array (PV+HotWater): 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.
3. In May 2012, students in UofL's Renewable Energy & Energy Efficiency Club, designed, constructed and installed low-cost 120-watt solar panels at the Garden Commons to power the ventilation system for the new greenhouse. Read more about the project.


A brief description of on-site renewable non-electric energy devices:

Data on Energy Generation is not available, but UofL does have such devices:
1. 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.
2. Sackett Hall Solar Array (PV+HotWater): 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.
3. 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.
