U.S. Building Operations Energy Consumption 2005-2030
n 2005, the U.S. Energy Informa-
tion Administration (EIA) Annual
Energy Outlook (AEO) forecast
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?

baseline (1975 = 100) began to de-

ASHRAE codes reached an EUI of 40.
