Can start of 365 data collection period be retroactive?

Hi, Susan! Check out this LEEDuser Tip Sheet on performance periods for O+M. Your specific question is addressed under "Addressing Dips In Performance."

But you're asking this under the v4.1 version of the credit, so I checked the v4.1 beta guide, and it says there is not really a performance period in the same way as under v4.

Your v4.1 O+M beta certification is based on the performance of the building/project spaces for a specific 1-year time period (365 consecutive days). Note that this is different from the “performance period” approach used in LEED v4.
Your project’s performance data is collected on a rolling basis, with the “current score” displayed based on the most recent 365 days. For LEED certification, you will need to define the specific 1 year time period that you would like your performance scores to be calculated for when you submit for certification review. All performance scores must use the same 1 year time period.

Seems like it just captures the whole year before you decide to push the button for submittal of the data. Does that help? Good luck!

Hi,

is that possible to calculate the score for a building that is not pursuing LEED certification yet?
I have a client that is deciding if they want to go for LEED or not, and asked me to do a provisional score for this credit.

this would be the first time I am doing this calculation, so I am a bit lost.

any chances you (the experts) could point me to some resources that would help me complete this task?

thanks
