dc.description.abstract	The use of whole building utility interval data for verifying energy savings from energy efficiency projects has become an attractive option as this data is increasingly available. Formal protocols, such as IPMVP Option C and ASHRAE Guideline 14, describe a whole building savings approach, but may require up to one full year of post-implementation data in order to claim annual energy savings. Many projects cannot absorb this long timeline. This paper builds on previous research and investigates strategies to reduce the required post- implementation monitoring time. Five grocery energy efficiency projects were evaluated using whole building electric interval data to investigate how data resolution, monitoring period length and timing of the post-implementation monitoring period impact the accuracy of annualized savings estimates.	en
