(2) if the participant retrofitted an old roof, 
which older roof product the new eligible cool roof 
product replaced or covered; and 
(3) what eligible cool roof product the partici-
pant purchased using the rebate. 
(f) AUTHORIZATION OF APPROPRIATIONS.— 
(1) PROGRAM.—There is authorized to be ap-
propriated to carry out the program established

(g) DEFINITIONS.—In this Act: 
(1) 3-YEAR
AGED.—The term ‘‘3-year aged’’ 
means, with respect to solar reflectance or thermal 
emittance of an eligible cool roof product, the solar 
reflectance or thermal emittance is tested after com-
pleting 3 years of field exposure, or tested after lab-
oratory exposure that has replicated the effects of 3 
years of natural exposure if the eligible cool roof 
product has begun but not yet completed field expo-
sure, in accordance with the most recent standard
