An EndoTherm pilot was run at Northeastern Illinois University (NEIU). EndoTherm was installed into three buildings; The Jacob H. Carruthers Center for Inner City Studies (CCICS), El Centro Building and the PE Comp Building. This case study reviews the first heating seasons consumption data.

Historical consumption was provided from January 2017 onwards to establish a baseline; normalized with Heating Degree Days (HDD) from Chicago O’Hare International Airport (at a baseload of 65°F). This data was used in regression analysis to create a predicted trendline to compare with post-EndoTherm consumption data. The baseline was then adjusted based on recent trend changes, for example CCICS showed a significant increase in consumption in the 8-month period prior to EndoTherm installation.

EndoTherm - NEIU Graph

The consumption for the month following EndoTherm installation was compared with the established baseline for all three sites. This consumption when compared with the predicted consumption (calculated from the baseline trendline) identifies the savings of the pilot. Only winter consumption was used in the analysis.

The regression graph above shows the improvement in performance from PE Comp Building. This shows a reduction on the predicted trendline and a sizable reduction compared to the consumption historically when the HDD was similar.


Site Predicted Consumption (thm) Actual Consumption (thm) Difference (thm) Saving
CCICS 76,772 65,894 10,878 14.17%
El Centro 68,627 44,443 24,183 35.24%
PE Comp 89,718 73,797 15,921 17.75%



Total Average Saving:


Total Cash Saving:

$30,012 (USD)

Total CO2e Saving:

302,383 lbs

Note: the saving at El Centro is higher than expected and likely impacted by other demand reducing variables. This value has been removed from the cumulative totals. Including El Centro the three installations saved $63,270.52.
