building? What makes it  
green? There are many details and  
considerations that go into creating  
such a structure. It becomes even  
more challenging when the intent is to  
build a structure that not only exceeds  
energy performance mandates, but  
one that also offers an eye-catching de-  
sign. Adding to the complexity, design  
it so that glass makes up a significant  
portion of the envelope.

Museum of African American History  
and Culture (NMAAHC) took place in  
February 2012 in Washington, D.C., it  
was one of the largest and most com-  
plex building projects underway in the  
country.This was in large part due to the  
challenges of constructing 60 percent of  
the structure below ground. Completed  
in late 2016, NMAAHC is the only na-  
tional museum devoted exclusively to  
the documentation of AfricanAmerican  
life,history and culture.It opened to the  
public in September 2016, and earlier  
this year was certified as LEED Gold,the and American history.The three-tiered vided additional design depth for the

and storefront systems.  
According to Enclos, “the 10-story  
museum (five above and five below  
ground) includes 250,000 square  
feet of building envelope, primarily  
consisting of a multi-layered skin  
with a permeable filigree exterior of  
bronze-colored panels, the Corona,  
that were inspired by southern iron-  
work. The panels act as a brise soleil,  
helping to reduce solar heat gain and  
glare while still providing the build-  
ing with openness to daylight. The  
facade program also includes sloped  
glazing, skylights, glass soffits, and  
storefront systems.”  
Glass products were also  
used extensively throughout  
the interior of the NMAAHC.  
Jeffrey Vaglio, vice president of  
the Enclos Advanced Technology  
Studio, adds that “the Corona panel  
brise soleil outer layer mitigates solar  
heat gain, reducing cooling demand,  
while the interior layer with insulat-

weather barrier.”
