Curious if folks know of any resources on hempcrete, specific to durability.  We have a one-story carbon-neutral operational energy project where the design team and client have bought into the aesthetics and carbon-sequestering potential of hempcrete, and amazingly it is looking to be no more expensive than a more typical concrete wall...

Hi all - Can you help me with a list of states with pending electrification/fossil fuel free ordinances? I am providing some technical aasistance for an article that is going to press soon. The author has listed WA, CO, and MA but I'm unsure how far each of these go and if it's technically correct to call them electrification ordinances.

I know there are a few of us WELL Performamce Testing Agents / Organizations represented in this group. In the wake of technology talks on this weeks update calls from IWBI, I'm wondering if anyone would be interested in a best practices and equipment small group discussion within the safe space of Green Gurus? Let me know! 

I'm hoping someone knows the anser to this question. For the LEED ND certification the minimum requirement is "The LEED project should contain at least two habitable buildings and be no larger than 1500 acres." Does habitable mean buildings with dwelling units?

I took a first pass at content for the Energy Audit best practice, see the uploaded file.

Hi all,

We are about to start a affordable housing passive house project in Boston and in a few presentations I've seen great signs that builders use to try to get the point across to subs as to how important air sealing is. Some are even quite funny! The builder we are working with does not have a sign like this, but is open to ideas.... Read more

Once you decide, please let us know who controls the domain name (e.g. bit-user.org or bitbuilding.org).  Ben will send them instructions for editing the... Read more

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. 

Hi - We have some projects within reasonable reach of ILFI's Zero Carbon Certification, which will require purchasing some off-site renewable energy. As a State Building Code Council member, I'm also eyeing the Zero Code which we will seriously consider in the next 12 months; this also requires a purchase of off-site renewable energy. 

I... Read more
