Building Technologies Goal
By 2025, the Building Technologies
Program will create technologies and
design approaches that enable the
construction of net-zero energy
buildings at low incremental cost.
Emerging Technologies Summary

Impact on U.S. Window Markets
(25 years in the Residential market)
• 1973: Typical Window:
– clear, single glazed,
– double or storm window in
north,
– Uaverage = .85 BTU/hr-F-sq.ft.
• 2002: Typical Window:
– 95% double glazed
– 50% have a low-E coating
– 30-65% energy savings vs.
1973
– Uaverage = .45 BTU/hr-F-sq.ft.
