The Deep Direct Use geothermal project has completed a preliminary assessment of steam use for greenhouses on UIUC campus. Steam usage in the greenhouses at Turner Hall and Plant Sciences building were compared with Lincoln Hall (pre and post renovations) for the period 2013-2018.

Generally, the steam use in greenhouses is 3-5 times higher (mmBTU per square foot) than in an academic building. Together, the greenhouses have produced ~25MT CO2/MWh) over the 5-year period.
