Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

I am diving back into Sefaira for the first time in a while, and the program still seems to be missing the ability to account for automatic daylight dimming in energy savings. Previously I had used an LPD reduction equivalent to emulate the savings automatic dimming would provide. Has anyone done a similar work-around? 

If anyone else has gotten confused going between parts-per-million and percentages (parts per hundred!) for material reporting here's a little infographic that might help. Feel free to use or improve!

Hi there colleagues!

Out of curiosity, do you plan on attending Greenbuild in person in San Diego in September? My staff asked me if we were going and my answer is partially contingent on the extent to which attending would mean getting to see some of our favorite people (read: all of you). Looking forward to taking the temperature of... Read more

Hi there SD Leaders,

We're running an LCA on one of our projects that's about to start construction that has had serious embodied carbon goals and I got a result that really surprised me. I haven't been able to find any obvious/glaring issues with the work, but these results are strange enough that I'm not feeling confident. I'm hoping... Read more

Hey all - sorry I won't be able to join our call today. I had a client request an emergency meeting today (boo) because corporate mandated that they eliminate fossil fuel use from all their buildings (yay!) by 2025 and they've got a project underway that needs to pivot quickly. 

Had I been able to join, I wanted to share this in case... Read more

Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more
