property placed in service during the tax year;
• Identify yourself as a designer or the building owner;
• Provide information on the person performing the
certification; and
• Provide information on the person completing the
allocation.

Who Must File

Individuals and business entities that qualify to claim the
deduction for qualifying energy efficient commercial

Energy efficient commercial building property
(EECBP) is property that meets the following criteria:
• Is depreciable property;
• Is installed on or in a building located in the United
States, and within the scope of Reference Standard 90.1
(defined below);
• Is installed as part of the interior lighting systems,
heating, cooling, ventilation, and hot water systems, or the
building envelope; and
• Is certified as being installed as part of a plan designed
to reduce the total annual energy and power costs with
respect to the interior lighting systems, heating, cooling,
ventilation, and hot water systems of the building by 50%
or more in comparison to a reference building which
meets the minimum requirements of Reference Standard
90.1.
Reference Standard 90.1 is the most recent Standard
90.1 published by the American Society of Heating,
Refrigerating, and Air Conditioning Engineers and the
Illuminating Engineering Society of North America which
has been affirmed by the Secretary, after consultation with
the Secretary of Energy, no later than the date that is 2
years before the date that construction of such property
begins.
Building square footage is the sum of the floor areas of
the conditioned spaces within the building, including
basements, mezzanine, and intermediate-floored tiers,
and penthouses with headroom height of 7.5 feet or
greater. Building square footage is measured from the
exterior faces of exterior walls or from the centerline of
walls separating buildings, but excludes covered
walkways, open roofed-over areas, porches and similar
spaces, pipe trenches, exterior terraces or steps,
chimneys, roof overhangs, and similar features.

Special Rules

A certification completed by a qualified individual is
required for both building owners and designers to claim
the deduction under section 179D for EECBP. The
certification must meet the requirements specified in
Notice 2006-52, Section 4.

A qualified individual is an individual that:
• Is not related to the person or entity claiming the
deduction;
• Is an engineer or contractor that is properly licensed as
a professional engineer or contractor in the jurisdiction in
which the building is located; and
• Has represented in writing that he or she has the
requisite qualifications to provide the certification required
under Notice 2006-52, Section 4, or to perform the
inspection and testing described in Notice 2006-52,
Section 4.05.

Cat. No. 93340H

greater using the regular method, the All systems, or “A”
column may be used. If 50% is not reached, list each
system separately among the “E,” “H,” and/or “L” columns.

An allocation of the EECBP deduction to the designer
of a government-owned building must be in writing and
meet the requirements of Notice 2008-40, Section 3.04, in
order for the designer to claim the deduction.

Interim lighting rule. If using the interim lighting rule,
enter the computed interim lighting applicable percentage
defined in Notice 2006-52, Section 2.03(2)(b)(ii). Do not
enter the reduction in power density in column 1(c).
If only the reduction in power density is known, use the
worksheet below to compute the interim lighting
applicable percentage. Enter the computed amount in
column 1(c) if the interim lighting rule is used.

Specific Instructions
Note. If claiming the EECBP deduction for more than four
properties, complete and attach as many Forms 7205 as
needed to list them. However, complete Part II, line 3 (for
total section 179D deduction) on only one Form 7205. The
line 3 amount on that form should include the combined
total for all properties reported on all Forms 7205. See the
instructions for Part II, line 3.

are the owner of the building and are claiming the
deduction for qualifying property installed on or in your
building.

Enter the lighting power density reduction
percentage . . . . . . . . . . . . . . . . . . . . . . . .

Note. An exception applies to warehouses. The reduction
in power density must be 50% or greater. If the property is
a warehouse and the reduction in power density is 50% or
greater, enter 100% in column 1(c), column L for the
property. If less than 50%, enter 0.

Designer of energy efficient commercial building
property (EECBP). In the case of EECBP installed on or
in property owned by a federal, state, or local government
or a political subdivision thereof, the deduction may be
allocated to the person primarily responsible for designing
the property in lieu of the owner of such property. Check
the “Designer” box if all the following are true:
• You are the person primarily responsible for designing
the EECBP (the designer);
• You created the technical specifications for installation
of the EECBP within a government-owned building. A
person that merely installs, repairs, or maintains the
property is not a designer; and
• The government building owner provided you a written
statement allocating the deduction to you.

Line 1, Column (d)

Check the box in column 1(d) only if the interim lighting
rule was used for the interior lighting system. Information
regarding the interim lighting rule can be found in Notice
2006-52, Section 2.03(1)(b).

Line 1, Column (e)

Use the Worksheet for Form 7205, Line 1, Column (e), to
compute the total potential amount per square foot. Each
property has a maximum amount per square footage limit
