For porcelain tile, BuildingGreen starts with the Green2 standard for sustainable tiling—ANSI A138.1 American National Standard Specifications for Sustainable Ceramic Tiles, Glass Tiles, and Tile Installation Materials. This is a multi-attribute... Read more

Team,

After talking to UL today, I thought it will be good for them to do a presentation on what they see in embodied energy/carbon road map of MEP equipment can be like.

Should we schedule them for a 30 minutes presentation in the next call?

Best,

Dear Colleagues,

I proposed CarbonCure for a project and the structural engineer in the meeting was opposed to it. He later sent me detailed reasoning by email. I have not used this technology and would like to hear other more experienced opinions on the technology. The project we are working on is well integrated with climate, 99% sDA,... Read more

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.

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 just saw this post from Conor on LinkedIn.

Starting in January 2019, all new Columbia Construction Company projects require LED temp lighting.

Are others doing this too? Frankly, given all the benefits and how quickly the industry is matured, it's hard for me to understand why anyone would use anything other than LEDs on a job.... 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...
