This notice sets forth interim guidance, pending the issuance of regulations, relating to the deduction for energy efficient commercial buildings under § 179D of the Internal Revenue Code. Specifically, this notice sets forth a process that allows a taxpayer who owns, or is a lessee of, a commercial building and installs property as part of the commercial building’s interior lighting systems, heating, cooling, ventilation, and hot water systems, or building envelope to obtain a certification that the property satisfies the energy efficiency requirements of § 179D(c)(1) and (d). This notice also provides for a public list of software programs that must be used in calculating energy and power consumption for purposes of § 179D. The Internal Revenue Service and the Treasury Department expect that the rules set forth in this notice will be incorporated in regulations.

.01 In General. Section 1331 of the Energy Policy Act of 2005, Pub. L. No. 109-58, 119 Stat. 594 (2005), enacted § 179D of the Code, which provides a deduction with respect to energy efficient commercial buildings. Section 179D(a) allows a deduction to a taxpayer for part or all of the cost of energy efficient commercial building property that the taxpayer places in service after December 31, 2005, and before January 1, 2008. (See section 2.02 of this notice.) Sections 179D(d)(1) and 179D(f) allow a deduction to a taxpayer for part or all of the cost of certain partially qualifying commercial building property that the taxpayer places in service after December 31, 2005, and before January 1, 2008. (See sections 2.03, 2.04, and 2.05 of this notice.) For purposes of this notice partially qualifying commercial building property is property that would be energy efficient commercial building property but for the failure to achieve the 50-percent reduction in energy and power costs required under section 2.02(1)(c) of this notice.

.02 Energy Efficient Commercial Building Property.

(1) In General. Energy efficient commercial building property is depreciable property that satisfies each of the following conditions:

(a) The property is installed on or in any building that is located in the United States and is within the scope of Standard 90.1-2001. (See section 5.02 of this notice for the description of buildings within the scope of Standard 90.1-2001 and section 5.06 of this notice for the complete description of Standard 90.1-2001.)

(b) The property is installed as part of—

(i) the interior lighting systems,

(ii) the heating, cooling, ventilation, and hot water systems, or

(iii) the building envelope.

(c) It is certified that the interior lighting systems, heating, cooling, ventilation, and hot water systems, and building envelope that have been incorporated into the building, or that the taxpayer plans to incorporate into the building subsequent to the installation of such property, will reduce the total annual energy and power costs with respect to combined usage of the building’s heating, cooling, ventilation, hot water, and interior lighting systems by 50 percent or more as compared to a Reference Building that meets the minimum requirements of Standard 90.1-2001. The required 50-percent reduction must be accomplished solely through energy and power cost reductions for the heating, cooling, ventilation, hot water, and interior lighting systems. Reductions in any other energy uses, such as receptacles, process loads, refrigeration, cooking, and elevators, are not taken into account in determining whether the 50-percent reduction is achieved.

(2) Maximum Amount of Deduction.

(a) In General. The deduction for the cost of energy efficient commercial building property installed on or in a building shall not exceed the excess (if any) of—

(i) the product of $1.80 and the square footage of the building, over

(ii) the aggregate amount of the § 179D deductions allowed with respect to the building for all prior taxable years.

(b) Application to Multiple Taxpayers. If two or more taxpayers install energy efficient commercial building property on or in the same building, the aggregate amount of the § 179D deductions allowed to all such taxpayers with respect to the building shall not exceed the amount determined under section 2.02(2)(a) of this notice.
