(relating to nonrefundable personal credits), as amended by this Act, 
is amended by inserting after section 25C the following new section:

``SEC. 25D. ENERGY EFFICIENCY IMPROVEMENTS TO EXISTING HOMES.

    ``(a) Allowance of Credit.--In the case of an individual, there 
shall be allowed as a credit against the tax imposed by this chapter 
for the taxable year an amount equal to 10 percent of the amount paid 
or incurred by the taxpayer for qualified energy efficiency 
improvements installed during such taxable year.
    ``(b) Limitations.--
            ``(1) Maximum credit.--The credit allowed by this section 
        with respect to a dwelling shall not exceed $300.

        taken into account.--If a credit was allowed to the taxpayer 
        under subsection (a) with respect to a dwelling in 1 or more 
        prior taxable years, the amount of the credit otherwise 
        allowable for the taxable year with respect to that dwelling 
        shall not exceed the amount of $300 reduced by the sum of the 
        credits allowed under subsection (a) to the taxpayer with 
        respect to the dwelling for all prior taxable years.
    ``(c) Carryforward of Unused Credit.--If the credit allowable under 
subsection (a) exceeds the limitation imposed by section 26(a) for such 
taxable year reduced by the sum of the credits allowable under this 
subpart (other than this section) for any taxable year, such excess 
shall be carried to the succeeding taxable year and added to the credit 
allowable under subsection (a) for such succeeding taxable year.
    ``(d) Qualified Energy Efficiency Improvements.--For purposes of 
this section, the term `qualified energy efficiency improvements' means 
any energy efficient building envelope component which is certified to 
meet or exceed the prescriptive criteria for such component in the 2000 
International Energy Conservation Code, any energy efficient building 
envelope component which is described in subsection (f)(4)(B) and is 
certified by the Energy Star program managed jointly by the 
Environmental Protection Agency and the Department of Energy, or any 
combination of energy efficiency measures which are certified as 
achieving at least a 30 percent reduction in heating and cooling energy 
usage for the dwelling (as measured in terms of energy cost to the 
taxpayer), if--
