For many years sales, marketing and even executive teams of green, sustainable construction material manufacturers have sold the advantages of using their systems over less "friendly" alternatives.

In the 12 or so years I have been exclusively involved in the industry, I have never heard this one:

      A staggering 26% increase in cognitive function           test scores was recently observed in workers               housed in green-certified buildings when                     compared to non green equivalents.

If your commercial product offering does conform to such standards, now is perhaps the time to include statistics from the below article.  Make your sales teams aware of it, slip it into technical literature, include it in your latest CPD seminars.  I hope it brings some value.
