ASHRAE 209 in all its glory has been uploaded. This will impact our architectural process, for better or worse, so we should embrace it and learn from it.

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...

What sorts of boilerplate and legalese will we need on the BIT User site? For example:

I'm not saying you need any or all of those, but I'm just giving a heads-up in case you need to check with your legal advisor.

I'm writing to pass along a... Read more
