Hi all!

I'm working on my first energy positive / passive house multifamily building and trying to figure out the trash/recycling chute. I am curious what solutions you have employed to make the trash chute air tight? We have excluded the whole chute from the envelope. Do you use airtight doors (and which ones?) at each floor trash/... Read more

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

Apologize in advance if this has been posted before but we are trying to get manufacturers of stage curtains to give documentation that proves that the product does not have halogenated fire retardants. Manufacturers say they don't have them or concentrations are limited to 100ppm but they don't seem to have documentation to provide for it.... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Is anyone else working on a project doing Living Building Challenge v4.0 Energy Petal? We're working through the Imperative 08 Net Positive Carbon Resiliency Strategy requirements that ask for the project to be habitable for a week in the event of an emergency. We're curious how others are defining "habitable" and what systems assumptions... Read more

Let me know! 

Hi Shane and Dennis,

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. 

I opened IE11 (Internet Explorer 11) today, and saw a message indicating IE11 will be retired June 15th, 2022. While I have no personal attachment to IE11, it was the only internet browser I could consistantly get to open LEED Online credit templates on the actual website. 

Has anyone found another way to be able to fill out LEED credit... Read more

Hi Green Gurus,

In this stressful time, I think it is important for us to continue to feel connected and supported.  Also, it is difficult to come to terms with the reality of what is happening.  So, I thought it would be helpful for us to share some information about the response of our respective firms to the Coronavirus.
