This extremely durable surface material already received plenty of LEED points for its high recycled content — and at $35sq/ft, EcoTop was a pretty good deal.

Add the controlled ventilation piece and the combustion safety piece and nobody dies and nobody gets sick and life is good.”  In other words, remove large holes in the building envelope, install a controlled ventilation system, and use sealed combustion or power vented appliances.
