Our project achieved LEED-EBOM v2009 certification in 2013. We are now attempting LEED-EBOM recertification under LEED v4. I am wondering how long the performance period is when moving to a newer version?
I have heard 3 months, as well as the traditional 12 months. A 3-month performance period could make sense when switching versions, as some of the credits and tracking metrics are more robust under v4. I would appreciate any advice and/or documentation that explicitly states the performance periods for this situation.
Thanks!
