Good morning, I had a question about recertification. My building is currently certified under V2.0 and we are up for recertification in 2015. We recieved certification in 2010. The question I have is for the performance period. Some places I read say you have to display information from the time you originally got certified(2010-present). Other documents said 12 months and I even found one that said the most recent 25% of performance period. We have the information from when we originally recieved certification but wanted to know if it is neccasary to provide 5 years worth of tracking or the most recent 12 months?
