The 2018 ENR Green Building Survey is due March 16th.  I'm sure you all know the metric they use to evaluate your ranking is solely the revenue from projects pursuing a green building certification in the previous calendar year.  Personally, I think this totally bogus.  How "green" a contractor is may correlate with how much revenue they have...
