tions provided under this subparagraph but 
may not substantively expand the exceptions. 
‘‘(2) REVISED STANDARDS.—
‘‘(A) IN GENERAL.—Notwithstanding any 
provision of this Act, if the requirements of

energy use standards for electricity used by ceil-
ing fans to circulate air in a room.
‘‘(B) SPECIAL
CONSIDERATION.—If the 
Secretary sets such standards, the Secretary 
shall consider—
‘‘(i) exempting or setting different 
standards for certain product classes for 
which the primary standards are not tech-

secondary design feature. 
‘‘(C) APPLICATION.—Any air movement 
standard prescribed under this subsection shall 
apply to products manufactured on or after the
