We're wrapping up a multi year project that went through multiple design changes, leaving us with a ton of material samples.  Does anyone know of a good place we could donate these samples to, to keep them out of the landfill.  I'm in the greater Seattle area.  Thank you for any suggestions.

Both Z Smith and Lois Vitt Sale have been notified that they have been elected to the College of Fellows of the AIA, class of 2018.

Hello, 

I am struggling with understanding if I should be using Annual Marginal Emission Factors (MEF) or Annual Average Emission Factors (AEF) for evaluating different building design decisions.
