Deduction for Energy Efficiency Commercial Buildings
Internal Revenue Bulletin: 2008-14
The Energy Policy Act of 2005 added section 179D to the Internal Revenue Code. Section 179D permits a deduction to the energy efficient property designer for the costs of installing certain energy efficient building systems in government-owned buildings. For the deduction to apply, the qualifying energy efficient building property must meet five general requirements:
1. The property is placed in service after December 31, 2005 and before January 1, 2008;
2. The property is installed in or on a building located in the United States;
3. The building is within the scope of Standard 90.1-2001, which deals with energy efficiency guidelines;
4. The property is installed as part of the interior lighting systems, the HVAC and hot water systems, or the building envelope; and,
5. An unrelated and qualified party certifies that the property will reduce the total annual energy and power costs by 50% compared to a reference building.
The deduction is for the cost of the qualifying energy efficient property, but it is capped at $1.80 times the square footage of the building, including mezzanines and other intermediate floors. For example, if a government entity places into service $500,000 of qualifying energy efficient building property in 2006 and has a 100,000 square foot building, the available deduction is limited to $180,000. On the other hand, if the government entity had only placed in service $150,000 of qualifying energy efficient building property, then the available deduction would be $150,000. NOTE: There are also reduced deductions available for partially qualifying property. continue reading…
