"URBANA — The University of Illinois’ glossy new building at Springfield Avenue and Wright Street represents the next step in its sustainability goals.

The four-story, 122,000- square-foot, $75 million Campus Instructional Facility is also the biggest geothermal installation on the UI campus.

Its geothermal system can pump 135 tons of hot or cool air into the building. That’s twice as much as the next biggest geothermal system on campus, and about 30 times the amount pumped into an average home.

“The whole world knows about solar and wind power and things like that — hydroelectric power, too — but that’s only the electric side of energy. Energy also includes heating and cooling,” said Morgan White, director of sustainability at UI Facilities & Services. “It’s truly transformative, because it’s moving into the phase of getting us clean thermal energy and not just clean electricity.”

Electricity provides heating and cooling as well, she said, but it’s primarily provided by natural gas, propane and other nonrenewable sources of energy.

The key to the geothermal endeavor? Forty boreholes dug into the Bardeen Quad next to Grainger Library. They’re 20 feet apart, 6 inches wide and drilled 450 feet deep.

Initially, the project required 60 boreholes, but UI researchers reduced that figure — and made the system financially feasible — by checking the thermal conductivity of different rock and soil layers, or the rate that heat passes through them, while considering the depth and flow rate of groundwater.

To keep the building temperate year-round, a mixture of water and glycol circulates from a heat pump in the mechanical room into a pipe that runs up and down the underground field of boreholes.

In winter, the pump pulls heat from the ground into the building. In summer, heat is pumped from the building back into the ground.

“It’s like when you have a bathtub that’s a little too hot or a little too cold, and you pour some water in and stir it up,” White said.

In all, the system reduces the building’s energy consumption by 65 percent compared to a typical heating/cooling installation, saving about $45,000 per year.

Student initiatives helped fund the state-of-the-art thermal system. The 18-member Student Sustainability Committee, funded by the annual “Green Fee” assessed on students, allocated $375,000 — or about 13 percent of the system’s cost — to the facility’s geothermal installation.

The building has a number of other unique features. It contains two dozen new classrooms — one of the highest figures on campus — replete with active-learning and distance-learning spaces. In the fall, engineering courses will occupy most of the space, along with math, statistics and other technical classes.

The facility is also the first UI building funded through a public-private partnership, which allows for tax-exempt financing.

Meanwhile, faculty and graduate students will use temperature information from a 385-foot-deep monitoring well, funded by Facilities & Services and the Institute for Sustainability, Energy and Environment, for continued research opportunities. 

As part of the Illinois Climate Action Plan, the university plans to get to net-zero carbon emissions by 2050.

Currently, around 12 percent of electricity is provided by renewable sources, like the solar and wind farms near campus, White said. But only 4.5 percent of the UI’s total energy use, counting thermal, comes from renewable sources.

“Clean electricity is important, but it’s not enough,” White said.

In the planning stages, the UI wasn’t supposed to start implementing geothermal systems until 2035, but a suggestion by Yu-Feng Forrest Lin of the Prairie Research Institute jump-started that process."

This is a list of projects that need students to work on.  It will be updated periodically by sustainability staff members, the last update was 6/24/21:

• Develop informational messaging about SmartWay, get more UIUC departments aware of the program, and coordinate a related student event.  Contact Morgan White at mbwhite at illinois.edu.
• Conduct a campus poll (fall semester 2021) regarding the Top 10 most iconic/significant/impressive trees on campus (including the arboretum). Develop an online survey tool (i.e., an online poll) whereby students and campus employees can nominate their favorite campus trees. Upon conclusion of the survey, work with Jay Hayek to tabulate and rank the results and create a publicly viewable ArcGIS Online StoryMap showcasing campuses Top Ten Trees. Prepare a presentation of results for the annual Arbor Day Celebration. Contact Jay Hayek at jhayek at illinois.edu.
• Follow through with Facility Liasons for implementation of recommendations from NRES 285: iCAP Sustainability Ambassadors class: Illini Union.
• Follow through with Facility Liasons for implementation of recommendations from NRES 285: iCAP Sustainability Ambassadors class: Huff Hall.
• Follow through with Facility Liasons for implementation of recommendations from NRES 285: iCAP Sustainability Ambassadors class: ECE Building.
• Follow through with Facility Liasons for implementation of recommendations from NRES 285: iCAP Sustainability Ambassadors class: Armory.
• Follow through with Facility Liasons for implementation of recommendations from NRES 285: iCAP Sustainability Ambassadors class: Bevier Hall.
• CCNet Website: Work with the Champaign County Sustainability Network (CCNet) leadership team to redesign and publish the CCNet website (old version is online at http://www.champaigncountynet.org/). There is a monthly brown bag sustainability networking event on the Third Thursday of each month, but the website hasn't been updated since 2016. Contact Morgan White at mbwhite at illinois.edu.
• We are seeking a student volunteer who can do tree identification for a series of trees in the Arboretum, and work with the University Landscape Architect, Brent Lewis, and the Superintendent of Grounds, Ryan Welch, to compare the tree identification to the draft tree inventory. Contact Morgan White at mbwhite at illinois.edu.
• If you have a project idea, please contact us at sustainability@illinois.edu, or submit it through the iCAP Portal Suggestions page.

Entomology Today released an article highlighting the strategy and benefits behind pairing solar energy with pollinator habitats. Supporting its claims with UIUC and Iowa State initiatives, the article discusses content such as the scorecard approach, efficiency of the positioning of planted vegetation, and restrictions from geographic locations.

The final stage of the Solar Farm 2.0 project is wrapping up this month with the planting of a native pollinator habitat. The farm will serve as a major demonstration and research site for pollinator-friendly solar arrays, with more than 6.5 million flowering plants and native grasses around the 54 acres of panels creating a natural habitat for birds and beneficial insects. With this second solar farm, the campus has achieved clean energy goals outlined in the Illinois Climate Action Plan (iCAP) nearly four years ahead of schedule. Clean energy production will now support roughly 12 percent of annual campus electricity demand. Congratulations to Facilities & Services for all of the hard work on this important project; iSEE and its SWATeam members were proud to provide key support for Solar Farm 2.0 by pushing for an increased renewable portfolio in the iCAP. Students in iSEE's sustainability minor also helped assess the new array's carbon footprint!

The Spring 2021 iSEE Quarterly Update (iQ) was released with the following message from Madhu Khanna, the Interim Director of iSEE:

Dear Colleagues,

Attached, please find the Spring 2021 “iQ” – the quarterly update from the Institute for Sustainability, Energy, and Environment (iSEE).

It has remained a busy time here on our campus, as we bolstered our outstanding Congress and Critical Conversation events with the addition of two experts — activist Catherine Coleman Flowers and nuclear expert Denia Djokić — who are serving as Levenick iSEE virtual resident scholars.

Thanks to the support of experts Eban Goodstein, Tami Craig Schilling, and Harriet Hentges, our new Environmental Leadership Program workshops for undergraduates were a rousing success.

And we were so pleased to have a mix of virtual and in-person Earth Month events to engage students, faculty, and staff from across our campus!

Please take a quick look at those updates and more in this six-page “iQ.” For more regular news, please sign up for our E-newsletter at https://illinois.edu/fb/sec/5031776.

Best wishes for the summer,

Madhu
