Tax Incentives for Energy Efficiency Upgrades in Commercial Buildings
On this page you'll find information about the tax deductions available for improving the energy efficiency of commercial buildings, as well as links to qualified software available for calculating these savings.
The Energy Policy Act of 2005 (EPACT) offered businesses tax deductions for the costs of improving the energy efficiency of commercial buildings. The Emergency Economic Stabilization Act of 2008 extended provisions in EPACT. The following tax incentives are available under this act.
Deduction of the Cost of Energy-Efficient Property Installed in Commercial Buildings
Make quick calculations of the estimated energy cost savings from efficiency improvements to your new or renovated commercial building with the 179D DOE Calculator.
A tax deduction of up to $1.80 per square foot is available for buildings that save at least 50% of the heating and cooling energy of a building that meets ASHRAE Standard 90.1-2001. Partial deductions of up to $.60 per square foot can be taken for measures affecting: the building envelope, lighting, or heating and cooling systems. This act extends the deduction through December 31, 2013.
Buildings must be within the scope of ASHRAE Standard 90.1-2001 including addenda 90.1a-2003, 90.1b-2002, 90.1c-2002, 90.1d-2002, and 90.1k-2002 (in effect as of April 2, 2003) and within the control of the building designer. Retrofit of existing buildings is also eligible for the tax deduction.
The 179D DOE Calculator can help estimate whether improvements could qualify for a federal tax deduction. This tool is designed to outline potential qualifications for partial deductions for envelope; lighting; and heating, ventilating, and air conditioning (HVAC).
Extension of Energy Investment Tax Credits
The 30% investment tax credits (ITC) for solar energy and qualified fuel cell properties are extended to January 1, 2017. The 30% ITC now also applies to qualified small wind energy property. The cap for qualified fuel cells increased to $1,500 per half kilowatt of capacity. Finally, a new 10% ITC is available for combined heat and power systems and geothermal heat pumps.
Accelerated Depreciation for SmartMeters and Smart Grid Systems
Currently, taxpayers generally recover the cost of smart electric meters and smart electric grid equipment over a 20-year period. This act allows taxpayers to recover the cost of this property over a 10-year period, unless the property already qualifies for a shorter recovery schedule.

Qualified Software for Calculating Commercial Building Tax Deductions
DOE provides a list of qualified software for calculating commercial building energy and power cost savings that meet federal tax incentive requirements. In addition to the name and version of the software, the list includes detailed information provided by the software developer.
Note: Every effort is made here to provide accurate information on these tax incentives; however, a tax professional should be consulted on questions for specific situations.
