Total energy consumption (all sources, excluding transportation fuels), performance year :
Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
A brief description of on-site renewable electricity generating devices :
IUB has solar photovoltaic systems installed and on the grid on top of four buildings. The Indiana Memorial Union system is rated at 2.1 kW; the Briscoe Quadrangle system is rated at 23.15 kW; the Tulip Tree residence hall system is rated at 6.44 kW; the E-House system is rated at 4 kW; and the newest system on the IU Art Museum is rated at 5 kW.
IUB has a microturbine inside the Central Heating Plant that works in parallel with the pressure reducing station valves. This turbine reduces the pressure of steam from 150 psi to 40 psi and produces electricity in that process. The microturbine is rated at 3560 MMBtu.
The Central Heating Plant also has a demonstration unit which produce both solar hot water and PV.
Non-electric renewable energy generated on-site, performance year:
A brief description of on-site renewable non-electric energy devices:
This figure includes thermal production of the McNutt Residence Hall solar thermal system. The Research and Teaching Preserve, Cyberinfrastructure Building (CIB), and Rose Residence Hall, and Spruce resident hall all utilize solar hot water but the current monitoring system does not allow us to list that production. We also are not listing the "E-House" geothermal unit as it is not metered.
Total 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, performance year:
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:
A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
Indiana University Bloomington purchases renewable energy credits from Sterling Planet Inc. The REC type consists of 50% wind and 50% small hydro, where generators are located nationwide. The majority of the energy is sent to seven buildings on campus that are moving towards a LEED silver status, and the remaining is used to offset additional LEED buildings, events, and other activities on campus. Although the amount purchased is concrete, when the University will use part or the entirety of the REC energy is up to their discretion. It is currently planned out over the next four years, but subject to change. The University may also decide to purchase more REC's within this time.
