Green Roofs and Healthy Buildings

Typical air we breathe contains about 20% oxygen gas under most conditions.  A stale, stuffy building may contain only 17 to 18%, levels far too low for optimal body health and brain performance.

Plant leaves clean the air and supply oxygen!




Yet oxygen levels in the rainforests can reach up to 24% of the ambient air!  We all know how refreshing it is to walk through the forest.



Plants produce oxygen during the photosynthetic process where carbon dioxide and water are changed into sugar and oxygen.  The sugar is used by the plant to grow and the oxygen pumped back into the air for us to breathe.

Air Intake over Green Roof!
One way green roofs can help create healthy buildings is through oxygen production around air intake vents in the Air Handling systems.

As the fresh air intake opens, the invisible cloud of high percentage oxygenated air enters the building, replacing stale CO2 with fresh, pure O2.

Increasing the building O2 content just slightly can have significant impacts on occupant health, attitude and productivity.

Green roofs for healthy buildings!

Great post Kevin. My latest blog post shows both the good and the bad of green roofing. http://heidler.com/2011/08/23/green-whats-good-and-whats-not/
