They do, seriously.  They are fine people with tons of information, and without them, all of us Architects would be, well, out of luck.

So, we first want to say THANK YOU to all of our contractor friends who took part in our Contractor Coffee Talk on Tuesday. THAT WAS AWESOME!

Some of us SDLers saw a need to create an online repository for the best simulation graphics and created IBPSA Project Stasio over the last couple of years. Along side graphics is a list of simulation questions (in progress) that we as architects may not know we could ask. The graphics are linked to answer the questions so our simulation... Read more

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more

Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

Acceptable regulations for... Read more

Thanks for any and all experiences!
