Double Skin Façade Project Stands  
as an Achievement in Sustainability  
cientists work constantly to im-  
prove the lives of the nearly 7.6  
billion people on Earth through  
advances in technology, big and small.  
Some of the greatest changes have come  
in the field of medicine. Engineers, ar-  
chitects, manufacturers, contractors  
and the materials they use can assist  
through their own advancements, that  
improve the occupant comfort level  
without polluting the surrounding  
The Jerome L. Greene Science Center  
will house dedicated space for Colum-

tinue their fight against Parkinson’s  
and Alzheimer’s diseases. It’s part of  
the first phase of the university’s new  
Manhattanville Campus in West Har-  
lem, New York.  
Building occupants will be sur-
