(c) ENERGY SAVINGS.— 
(1) IN GENERAL.—Reductions in whole home 
energy consumption under this section shall be de-
termined by a comparison of the simulated energy 
consumption of the home before and after the ret-
rofit of the home. 
(2) DOCUMENTATION.—The percent improve-
ment in energy consumption of a home under this 
section shall be documented through— 
(A)(i) the use of a whole home simulation 
software program that has been approved under 
the Weatherization Assistance Program for 
Low-Income Persons established under part A 
of title IV of the Energy Conservation and Pro-
duction Act (42 U.S.C. 6861 et seq.); or 
(ii) a equivalent performance test estab-
lished by the Secretary, in consultation with the 
Administrator; or 
(B)(i) the use of a whole home simulation 
software program that has been approved under 
RESNET Publication No. 06–001 (or a suc-
cessor publication approved by the Secretary); 
(ii) an equivalent performance test estab-
lished by the Secretary, in consultation with the 
Administrator;
(iii) a State-certified equivalent rating net-
work, as specified by IRS Notice 2008–35; or 
(iv) a HERS rating system approved or re-
quired by the law of the State in which the 
home is located. 
(3) MONITORING.—The Secretary— 
(A) shall continuously monitor the software 
programs used for determining rebates under 
this section; and 
(B) may disallow the use of software pro-
grams that improperly assess energy savings. 
(4) ASSUMPTIONS
AND
TESTING.—The Sec-
retary may— 
(A) establish simulation software program 
assumptions for carrying out paragraph (2); 
(B) require compliance with software pro-
gram performance tests covering— 
(i) mechanical system performance; 
(ii) duct distribution system efficiency; 
(iii) hot water performance; or 
(iv) other measures; and 
(C) require the simulation of pre-retrofit 
energy usage to be determined by verified pre- 
retrofit energy usage.
(5) RECOMMENDED MEASURES.—Software pro-
grams used under this subsection shall have the abil-
ity at a minimum to assess the savings associated 
with all the measures for which rebates are specifi-
cally provided under the Silver Star Home Energy 
Retrofit Program. 
(d) AMOUNT
OF REBATE.—Subject to subsection 
(e)(2), the amount of a rebate provided under this section 
shall be— 
(1) $3,000 for a 20-percent reduction in whole 
home energy consumption; and 
(2) an additional $1,000 for each additional 5- 
percent reduction up to the lower of— 
(A) $8,000; or 
(B) 50 percent of the total retrofit cost. 
(e) VERIFICATION AND CORRECTION OF WORK.— 
(1) REIMBURSEMENT.—On submission of a 
claim by a rebate aggregator to the Federal Rebate 
Processing System, the Secretary shall provide reim-
bursement to the rebate aggregator for energy-effi-
ciency measures installed in a home, subject to para-
graphs (2) and (3). 
(2) VERIFICATION.— 
(A) IN
GENERAL.—Subject to subpara-
graph (B), all work and energy savings projec-
tions conducted with respect to a home as part 
of a whole-home retrofit by an accredited con-
tractor under this section shall be subject to 
random field verification by an independent 
quality assurance provider at a rate of— 
(i) 15 percent; or 
(ii) in the case of work performed by 
an accredited contractor using a certified 
workforce, 10 percent. 
(B) VERIFICATION
NOT
REQUIRED.—A 
home shall not be subject to field verification 
under subparagraph (A) if— 
(i) a post-retrofit home energy rating 
is conducted by an entity that is an eligible 
certifier in accordance with— 
(I) RESNET Publication No. 
06–001 (or a successor publication 
approved by the Secretary); 
(II) a State-certified equivalent 
rating network, as specified in IRS 
Notice 2008–35; or 
(III) a HERS rating system re-
quired by the law of the State in 
which the home is located;
