You’ve probably heard that wood products are carbon neutral. You might also have heard that timber harvesting causes immense carbon emissions.

Which is it?

Could it be both?

Gurus -

I'm looking for (or to build) a set of US district energy projects for developer-led mixed-use/residential neighborhoods/districts.  Does anyone have a resource for this or have started something similar?   

I am not a member of IDEA but utilize their site quite often. Any other resources come to mind?  I'd be happy to... Read more

Hi Leaders,

If your experience was anything like mine, it was a stressful night. I'm feeling a hunger for talking with smart, passionate people about what this all means.

I'm not interested in making this into a political forum--we can all get plenty of that elsewhere. But if you'd like to hang out and just process how you're... Read more

I'd love to hear thoughts from the design, consulting, and contracting firms in this group about ways to make our specs more inclusive, or at least less exclusive to minority and women owned contractors and subcontractors and others that have not had the benefit of what a recent "Equity in Specs" presenter termed the "Fathers / Brothers / In-...

We are T-minus two days from the ILFI unconference and I am looking forward to seeing a bunch of you there.  I have a vague memory about there being a meet up scheduled - can somebody remind me of where/when.

Also, can folks that are speaking post a reply about when their session is and what the topic is please.

Thanks in advance... Read more

Is there a way for southface staff or guest experts to "pin" or "tag" the "right" answer in a forum question? It might be useful to designate the right answer and pin it to the top of a forum thread. I don't want the answer selected via crowd source but by staff or volunteers. Thanks.
