said that building operations energy  
consumption would increase from 40  
quadrillion BTUs (quads) to 56 quads  
in 2030. However, the 2017 EIA AEO  
shows that number decreased to 37  
quads. What changed? What do these  
changes mean for glazing industry op-  
portunities in the future?

and commercial markets. By 2010, the  
ASHRAE codes reached an EUI of 40.
