Hello All,
Checking in on experience with Armstrong's Tectum E-N with NEOPOR Graphite polysytrene GPS rigid foam insulation core in roof panels for exposed structure?
BASF says that NEOPOR uses up to 30% less material than other rigid foam; it is greenguard gold cerified. 

Interesting that the NEOPOR increases in R-value as... Read more

Hi SCL,

I realize that there are already a couple of threads on this topic, but I didn't see anything from the past year.  We have been trying (unsuccessfully) to work with large rental companies to request jobsite trailers that are at a minimum energy efficient, and ideally solar/battery ready and/or built to passive house or similar...

Do any of you have experience with Design For Freedom yet? It came to my attention and I'm trying to investigate. I would love to hear feedback and experiences that you may have at this point. It seems like an opportune moment for this issue of forced labor (yikes! so much I don't know...) to come to the forefront, and I'm curious to hear how... Read more

Hi - I'm wondering if you have recommendations for a web/mobile app for occupants to self-assess comfort at regular intervals. I've downloaded comfy, but it wants to actually DO something about thermal discomfort by alerting discomfort and connecting, I believe, to the BMS. We just want to collect information at this point. And since I'm a... Read more

Hello all, 

Many of you have been asking about the CC reporting template for 2023 projects. It is still in-progress, but we can promise a huge upgrade from the past couple of years. In particular, the new template is designed for ongoing project tracking over the course of the year (rather than purely documentaion after the fact).  ... Read more

Here's a file upload.

Hi! Over the last 10 years, the firm where I work in Boston has predominately designed housing & senior living projects in the the Boston Metro region, with the occassional project in NH, CT, RI, and NY. We have built projects as far south at DC, but never designed anything to my knowledge in California in our 55 years of operation. A... Read more

Wondering if anyone has a slide presentation on the Framework for Design Excellence that they would be willing to share (to present to students). Rather than defining my request as lazy I'd like to offer up the qualification of efficiency.

Know any awesome sustainability leaders within GC or CM firms? They can be at mid-sized or large construction companies—any firm in the ENR top 400 qualifies for sure, others might need some vetting. The key is people who have sustainability as the focus of how they spend their time--either formally by title or otherwise. 

We want to... Read more

I know that there is a risk of starting a whole flurry of congrats through the forum, but this is a biggie, and deserves some recognition:

Congratulations Andrea and Melanie!! Huzzah!!

And a reminder--If you want to reach out to them privately, rather than through the forum, with your message, you can see anyone's email address by... Read more

Hi all!

I've heard several people talk about developing tools for assessing/codifying a client's values for a project as part of an integrated design process (ie. a set of questions, survey, etc.). Would anyone be willing to share?

(Z, are you listening? I specifically recall you mentioning a tool like this...)

Thanks!... Read more
