Although the ENERGY STAR models were only changed for a specific subset of properties in the August 2018 update, all property types could have experienced a change in metrics due to the updated site-to-source conversion factors for several fuel types. Specifically:
- Electricity site-to-source conversion factor dropped from 3.1 to 2.8, which impacted all properties that use electricity. This update reflects improvements to the electric grid’s efficiency.
- District chilled water site-to-source conversion factor dropped from 1.00 to 0.91
Note: None of the data that you "input" into Portfolio Manager has been changed. This includes: meters, meter entries, property uses, property use details, and basic property information.
