Reaching out to the collective knowledge here.  With interest in circular economy and building reuse growing, is anyone leading the charge for the concept of building reuse as a tool for maintaining community identity?  Has anyone seen successful projects with this concept in mind?  I was just in a discussion with a bunch of SDLers, and while...

Columbia already offers access to free EV charging for our field employees. Of the few projects that have have opted in so far, we've had to custom design and intall EV charging setups. It's good that we're doing this, but it won't scale quickly enough and cost effectively.  I think a practical next step is working with trailer companies so... Read more

For those of you working in jurisdictions with both prescriptive and performance-based commercial energy code pathways, roughly what percentage of your projects are using the performance pathway? How do your project teams decide which pathway to follow?

In Minnesota we are seeing very few projects pursuing the performance pathway,... Read more

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 everyone,

Thanks so much again to everyone who attended the Spring 2024 SCL Summit. The report is now available and is a public document that can be shared.

Please feel free to email me with any questions. Enjoy!

Hi Gurus!

I'm desperately seeking any case studies (past/currently on the boards) of labs that have been designed without natural gas infrastructure (the topic I have to debate is about commercial spec labs but any lab case study, wet or dry, is welcomed). This is for a development authority that will be setting guidelines for new... Read more

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

Hi Shane and Dennis,

What return address should we use for BIT User forum notification emails?  Ben suggests something like no-reply@bit-user.org but whatever you like is fine.

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

I was wondering if any design or contractor friend here can kindly share the carbon emission factor of excavation during construction. 

I found a paper that provides energy use rate per cubic meter and associated carbon emission in kgCO2 for different phase of construction such as excavation earth work, pouring and lifting concrete,... Read more

With the increasing need to support design with techncial expertise, I am curious to hear how others are meeting this challenge.  Do you build energy models in-house?  Do you have a team of experts whose sole responsibility is to support design teams with tasks such as energy modeling and LCA, or is that expertise distributed throughout the...

Textiles have some of the worst environmental records of any product found in our buildings. Textile production uses a number of hazardous chemicals and pollutes water; and its environmental impacts often affect our most vulnerable populations.

BuildingGreen favors textiles made using fibers and manufacturing processes that have low... Read more

BuildingGreen recommends low-emitting acoustic ceilings that do not contain formaldehyde resins or PVC coatings. Look for those that have C2C Silver or Gold certifications, are Declare Red List Free, and are third-party certified for low emissions using CDPH Standard Method. We also prefer wood ceiling products with FSC certification. The... Read more

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
