Hi All,

I have a commercial restauranter in Colorado who is (reluctantly) considering induction cooking. Does anyone know of any good resources out there that can help make the case for this? That would include testimonials, research, videos, testimonials, or whatever else can help get a commercial kitchen comfortable to moving to... Read more

Hello all,

Does anybody know of a substitute for Ecotect's solar tool? I use it to very quickly test shade options and I love how I can easily test horizontal and vertical elements, tilting and rotating them. I can have a window with the façade on one side and the sun path with the shadow mask on the other side. It is easy to use and... Read more

I think they look great - thanks to BuildingGreen for setting this up!  A few comments/questions:

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 Everyone! 

I am building our internal/firm resources around sustainable design, and creating our post-occupancy evaluations is one of those resources. Does anyone have references or resources they'd recommend me to look into for post-occupancy evaluations? So far I am considering a few evalutation types: building user input, building... Read more

Hi all - 

I have heard a good deal about SBTI in the last while and am wondering about this group’s firms’ engagement with them. We reported one year through CDP, and it was not very useful. It focused entirely on Scope 1 and 2 emissions, which are over 1000x times less than our semi-controllable Scope 3 (buildings’ embodied carbon and... Read more
