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,

As discussed in our monthly meetings, we are assembling an industry push to expand the availability of embodied carbon data for MEP equipment. Our first steps are to send a letter to industry announcing a call to action and future educational webinars on the topic. In a similar manner as the electrification letter by the SMEP... Read more

Little things make a big difference in MEP systems. Pumps, fans, ducts, and dampers are at the heart of performance.

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.

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 can link to those documents from the site footer.

Fellow SCLers,

This is a small ball item, but I recently had a conversation with a safety glove manufacturer called Traffi. They make PPE, but in particular they have a line of gloves that they promote as carbon neutral. Their organization's operations are offset with retired RECs, but one line of their gloves, LXT, is offset by a... Read more

Hi folks,

I’m sure most of you know Gail Brager, or at least know of her. For those who don’t, she helps run UC Berkeley’s Center for the Built Environment and is a long-time champion of all the things that make buildings work for their occupants. Perhaps most notably, she was a co-author of the Adaptive Thermal Comfort option in ASHRAE... Read more

Does anyone know about temporary flushout equipment that could be used to augment a building's systems to get additional CFM of OA during construction?  For our non-laboratory type projects the flushout period ends up being too long, especially in either humid summers or frigid winters (Pennsylvania).

Hoping that some of you on either... Read more

Hi Green Commons,

It’s been eerily quiet here since Tuesday night. I’ve been quiet mostly because I just didn’t know what to say. The election results are certainly a blow to pretty much everything we’ve been working for. There is so much we don’t know about things might play out, but I’m feeling a range of emotions ranging from... Read more

We are cautiously rekindling the age-old debate: how are we balancing modeling software for design /visualization and performance analysis during early phase of design.  

We are heavy SketchUp users for early design, and most of our staff have access to COVE tool for early performance analysis. Problem is, I’d rather use Revit to COVE... Read more

Dear all,

A mechanical engineer on a healthcare project we are working on has asked for help in dividing the ventilation calculations between ASHRAE Standards 170 and 62.1; can anyone here help shed some light on it?

Hi All,

I just tried to post a minute ago but it said my connection was lost, so I'm starting over again. You may see two similar posts from me.

Alejandra and I started a document (attached) with ideas on how we can tackle some of the issues we are currently facing with zero waste, as a follow up to our conversation last Friday... Read more

Hi all,

We are growing our sustainability group at Flad -- we have a great opportunity to make significant progress as we approach 2030, and we are currently looking for someone to join us in our Madison office. If you know someone who is looking for an entry-level sustainability position, and would enjoy living in Madison, Wisconsin, my... Read more
