Millersville University - Luek Hall PA, United States
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.
The consumption each month post-EndoTherm install was compared with the predicted consumption:
|Predicted Consumption (CCF)||Actual Consumption (CCF)||Difference (CCF)||Difference|
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).
