Hey all,

Thanks to everyone who joined today's peer network webinar - it was great to share what our working group has been developing in the last year. This group gathered to work through a series of decision-making trees to publish some kind of relatively repeatable guidance for how to advance this conversation with a variety of owners...

Hi All,

I just became aware of the attached detail (if I uploaded it correctly) for a project in Portland, OR going out for permit at the end of this week.  Has anyone located the radiant tubing at the bottom of concrete like this before?  It doesn't sit right with me, though I cannot pinpoint exactly why.  Our consultants and the...

Here is a fundamental question regarding measuring operational carbon emissions that I'm sure many of you can clarify for me:  Let's say you are considering design options and you want to know the relative contribution of GWP of adding an additional inch of continuous insulation to the building envelope.  The GWP from embodied carbon will...

Hello, Green Gurus!
It was lovely to see some familiar faces (and names) in this afternoon's webinar about Low Carbon Specs. A little personal info, but I have just recently returned from maternity leave, and plugging back in to this network of passionate sustainability professionals is one of the things that actually made me look forward...

Does anyone have a "healthy material" exterior bleacher benchtop (beyond natural wood or metal) recommendation for a public high school track and field? 

How do we discern between fiberglass, recycled plastic or HPDE?  Is there a rule of thumb on how to advocate for specifying a "not as bad" material? 

The project is in a coastal... Read more

Hello Sustainable Construction Leaders,

It's come to our attention that although we shared the slides from last fall's all-network Show & Tell in Atlanta, we neglected to include the presentations from the SCL Summit itself. Since we believe in "better late than never," here they are!

As a reminder: we have permission from... Read more

Hi Gurus,

It seems odd to think about leases now, during a time when most business are giving up leases or reducing their footprints, but there are still leases going on! Please share this link to any clients of yours who might be interested and sign up yourself if you want to advocate to your clients to consider these leases!

Hello! 

We have several projects that are either pending ILFI Zero Carbon certification or the owner is planning to purchase offsets to cover construction emissions. Thus far, I have not considered this in our corporate footprint reporting. However, we are including A5 emissions whenever feasible and multiplying that performance over the... Read more

I'm working with a project team that is looking into bird control options to prevent nesting/roosting/pooping on the scrim that is designed to scrim their building's facade.  They are looking at electrified tape, repellents, laser systems, etc -- Options that don't dramatically impact the building design.  The products they're looking at claim...

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.

Because board insulation is used on the building exterior, it is not always subject to the same material health and emissions requirements as batt insulation used inside the... Read more
