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)

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

This is a test for surveys.

I needed to find something low-contrast that wouldn't compete with the text. I initially tried some of the stock photos... Read more

Hi all, 

Internally in our organization, we seem to have plenty of horizontal (infrastructure) resiliency expertise, but I'm finding the vertical resources to be lacking. I'm hoping to build a collection of beginner- to intermediate-level resources to help guide practice/design standards for our reference. Any pointers on good info... Read more

Love the profile of Anica as the "featured member" on AIA's website--congratulations, Anica!
