Has anyone done inherent bias training in their firm, and if so, how'd it go? Do you have someone you'd recommend as a trainer/facilitator?   Thanks!

This question of what equity looks like in project design is one I have been musing on for a while now, and I was excited that several of us were able to talk about it at the SDL Summer Summit earlier this month.  That conversation has prompted me to post here, asking what all of you think equity looks like in project design... with a few...

Hi All, 

My understanding is that SCL reporting is only for refrigerant use, or recharging for headquarters. I've asked our MEP contractor for a list of our 21 units, refrigerant use, and what quantity of refrigerants were used to charge equipment during installation or service.  

Is anyone tracking this for job sites?... Read more

I was talking to Nadav recently about job posting opportunities through Building Green and/or through the Peer network.  He shared this topic has been discussed in the past, and thought I should send a question out to the network.  I am guessing many of you are looking for talent right now too?  Wouldn't it be cool to know people of have been...
