Brand new building - LEED EB?

Marcio, the limiting factor is that you need 12 months of energy performance data. (You need other performance data as well, but less than 12 months' worth in other cases.)

Marcio Tristan's quite right...the only problem with the 12 months of energy bills is that in any brand new building the opening 1 or 2 months energy can be 'all over the place' and it may take a quarter to settle down. As Energy Star uses a rolling 12 months those opening months, if a reflection of the building settling down, can throw the Energy Star off...and of course you'll need to wait a few months before the numbers you are uploading in Energy Star actually do reflect the real Energy Star of the building.
