Curious on stories when IAQ testing for LEED or WELL didn't come back with "all clear, everything's good" results we all hope for. 

I have a project right now where we are tracking down suspicious sources and look forward to telling the full story when it's done being written. 

Thought maybe this would be a good safe space to talk... Read more

Hi folks,

I’m sorry to be so last minute with this. LEED v5’s second public comment period ends TOMORROW (Monday, Oct 28). As it currently stands, LEED has eliminated its preferential support for FSC over other forest certification programs and is silent on climate-smart forestry.
