Some options are PipeFlo, AFT Fathom, PipeFlow (eerily similar name to first option), COMSOL Pipe Flow Module. 

Applications could range from general system troubleshooting, pump sizing, to district hydronic system network analysis. 

Best,... Read more

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

Hello All,

A group of us (three architects and a builder- sounds like there should be a joke here) were debating this and we  are stumped.

Application: Residential exterior trim.

50 year warrantied composite product of agricultural byproduct with PVC (EPD not published yet) vs 100 year (if primed on all sides and painted or... 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. 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
