For each of the credits under subsections (c) through (h) of this section, the credit may not be allowed for any taxable year unless: the taxpayer has obtained and filed an initial credit certificate and an eligibility certificate issued under subsection (k) of this section; a certificate of occupancy for the building has been issued; and the property with respect to which the credit is claimed is in service during the taxable year. The total amount allowed in the aggregate for all credits under this section may not exceed the maximum set forth in the initial credit certificate obtained under subsection (k) of this section. In determining the amount of the credits under this section, a cost paid or incurred may not be the basis for more than one credit. For the taxable year that is the credit allowance year, an owner or tenant may claim a credit in an amount equal to 8% of the allowable costs paid or incurred by the owner or tenant for the construction of a green whole building or the rehabilitation of a building that is not a green whole building to be a green whole building. The allowable costs used to determine the credit amount allowed under this subsection for a green whole building may not exceed in the aggregate: $120 per square foot for that portion of the building that comprises the base building; and $60 per square foot for that portion of the building that comprises the tenant space. For the taxable year that is the credit allowance year, an owner may claim a credit in an amount equal to 6% of the allowable costs paid or incurred by the owner for the construction of a green base building or the rehabilitation of a building that is not a green base building to be a green base building. The allowable costs used to determine the credit amount allowed under this subsection for a green base building may not exceed, in the aggregate, $120 per square foot. For the taxable year that is the credit allowance year, an owner or tenant may claim a credit in an amount equal to 6% of the allowable costs for tenant improvements paid or incurred by the owner or tenant in the construction or completion of green tenant space or the rehabilitation of tenant space that is not green tenant space to be green tenant space.

By regulation, the Administration shall adopt standards for a building to qualify as a green base building eligible for the tax credits under this section that are consistent with the criteria for green base buildings set forth by the United States Green Building Council or other similar criteria. The regulations adopted under this subsection shall provide that the energy use shall be no more than 65% for new construction of a base building, or 75% in the case of rehabilitation of a base building, of the energy use attributable to a reference building that meets the requirements of applicable energy efficiency standards. By regulation, the Administration shall adopt standards for tenant space to qualify as green tenant space eligible for the tax credits under this section that are consistent with the criteria for green tenant space set forth by the United States Green Building Council or other similar criteria. The regulations adopted under this subsection shall provide that the energy use shall be no more than 65% for new construction, or 75% in the case of rehabilitation, of the energy use attributable to a reference building that meets the requirements of applicable energy efficiency standards. On application by a taxpayer, the Administration shall issue an initial credit certificate if the taxpayer has made a showing that the taxpayer is likely within a reasonable time to place in service property for which a credit under this section would be allowed. The initial credit certificate issued under this paragraph: shall state the earliest taxable year for which the credit may be claimed and an expiration date; and shall apply only to property placed in service on or before the expiration date. To avoid unwarranted hardship, the Administration at its discretion may extend the expiration date stated under an initial credit certificate. The initial credit certificate shall state the maximum amount of credit allowable in the aggregate for all credits allowed under this section. The Administration may not issue initial credit certificates, in the aggregate, for more than $25,000,000 worth of credits. Except as provided in subparagraph (vii) of this paragraph, initial credit certificates shall be limited in their applicability, as follows: Credits in the aggregate      With respect to taxable years may not be allowed         beginning: for more than: $1 million               2003 $2 million               2004 $3 million               2005 $4 million               2006 $5 million               2007 $4 million               2008 $3 million               2009 $2 million               2010 $1 million               2011 As of the end of a calendar year, if certificates for credit amounts totaling less than the amount permitted with respect to taxable years beginning in that calendar year have been issued, the maximum amount that may be allowed for taxable years beginning in the subsequent calendar year shall be increased by the amount of the preceding year’s shortfall. The Administration may not issue an initial credit certificate after December 31, 2011. On January 1, 2004, and each year thereafter, the Administration shall provide to the Comptroller a list of all taxpayers in the prior taxable year that have been issued an initial credit certificate and shall specify for each taxpayer the earliest taxable year for which the credit may be claimed and the maximum amount of the credit allowable in the aggregate for all credits allowed under this section. For each taxable year for which a taxpayer claims a credit under this section with respect to a green whole building, green base building, green tenant space, fuel cell, photovoltaic module, or wind turbine, the taxpayer shall obtain an eligibility certificate from an architect or professional engineer licensed to practice in this State. An eligibility certificate issued under this paragraph shall consist of a certification, under the seal of the architect or engineer, that the property that is the basis for the credit that is claimed is in service and that: the building, base building, or tenant space with respect to which the credit is claimed is a green whole building, green base building, or green tenant space; and any fuel cell, photovoltaic module, or wind turbine with respect to which the credit is claimed constitutes a qualifying alternate energy source and is fully operational. The certification under subparagraph (ii) of this paragraph: shall be made in accordance with the regulations adopted by the Administration under this section specifying the standards and guidelines for each credit under this section; and shall set forth the specific findings on which the certification was based. The taxpayer shall file the eligibility certificate and the associated initial credit certificate with the taxpayer’s income tax return and shall file duplicate copies of the eligibility certificate with the Administration. The eligibility certificate shall include: sufficient information to identify each building or space; and any other information that the Administration or the Comptroller requires by regulation. If the Administration has reason to believe that an architect or professional engineer, in making any certification under this subsection, engaged in professional misconduct, the Administration shall inform the appropriate professional board of the suspected misconduct. The Comptroller and the Administration may adopt regulations necessary to carry out the provisions of this section. Regulations adopted under this section shall construe the provisions of this section in such a manner as to encourage the development of green whole buildings, green base buildings, and green tenant space and to maintain high, but commercially reasonable, standards for obtaining tax credits under this section.
