EndoTherm was piloted by FarmHannong in two of their R&D Glass Greenhouse buildings in Nonsan-si, Chungcheongnam-do, South Korea. EndoTherm was installed into each building on December 28th 2022.
For each site. LPG consumption from 2022 (Jan-Dec) was normalized using Heating Degree Days (HDD) from Buyeo Weather Station at a base-load of 18.5°C. A linear trend-line is used to predict consumption using known HDD values for each month in 2023.
The EndoTherm pilot was run for 8 months between January 2023 and December 2023. 4 months over the summer (June – September) were excluded as the heating system was not in use.

Results
The analysis after 8-month pilots shows an average saving of 11.75%.
The two projects saved a combined 2,260m3. A single m3 of LPG is equivalent to 1.8315kg of LPG. At 1,243.39 KRW per kg, the pilots saved a combined 5,256,627KRW. This means that the two pilots paid back their initial investment within the 8-month pilot period.
Carbon Reduction Equivalents:
The pilot also saved 6,444kg of CO2e, which is equivalent to:
