Greetings Gurus, following the AIA COTE Design for Economy concept, does anyone have a resource for a list of building efficiency ratio "targets" by space type? I've always struggled with this initiative. 

I was recently asked about potentially specifying concrete with wood nanoparticles and concrete with biochar as a way to further lower the embodied carbon and to increase concrete strength.  These approaches are something I know nothing about, and wondering if anyone in this group has any experience and/or observations that might be relevant to...

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

Hi Fellow GG: I just wanted to make sure everyone saw the great announcement from the White House yesterday about Code updates to address energy efficiency and resilience. It's great to see these kinds of initiatives that hopefully can continue for a few more years. So let's try to take advantage of them (said by someone who lives in Missouri... Read more

Are FSC glulams available? By many manufacturers? Which ones?

Hi!

I'd love to hear what you all--especially the New Yorkers--think about the newly adopted gas ban. Is this the bill we were hoping to see? Any concerns or questions?

One question I have--maybe just reveals my ignorance--but it seems to leave the door open to steam hookups, which I guess are still an option through much of... Read more

Hey All!

One of the initiatives from our first meeting in Chicago was to gather and develop resources related to plug and process loads in buildings which will help us all with: energy modeling, equipment sizing and power distribution.  We had our first call this morning and are rolling.  Aspirations are that this could turn into a...
