The performance of EndoTherm is being piloted by Millersville University at the Susan P. Luek Hall (formerly named Byerly Hall). The building, established in 1929, was initially a laboratory school for the college but now houses the Universities psychology department.
A baseline was constructed comparing historical consumption from September 2017 until August 2019 with heating degree days (HDD) from the nearby airport at Lancaster Airport (65°F chosen baseload).
Analysis of the baseload showed a notable increase in consumption since summer 2018 and the baseload was subsequently altered to include this.
Results
The consumption each month post-EndoTherm install was compared with the predicted consumption:
| Predicted Consumption (CCF) | Actual Consumption (CCF) | Difference (CCF) | Difference |
|---|---|---|---|
| 11,741.90 | 10,838 | 903.90 | 7.70% |
After seven months the consumption is 7.7% lower than the predicted consumption. This site has a notable baseload (an average of 35% of consumption based on the historical data). EndoTherm can only impact the consumption impacted by HDD (aka space heating) thus the space heating saving is 11.71%.

During the pilot period Luek Hall underwent some scheduling and demand changes. In December 2019 set points were increased for a few weeks to coincide with colder than anticipated temperatures. Usage increased in March 2020 most likely due to an increase in fresh air ventilation on site which co-incides with the COVID-19 outbreak. These have not been removed from the analysis, but removal of these two months increases savings to 11.57% (18% removing baseload).
