179D Tax Deduction

The Energy-Efficient Commercial Buildings Tax Deduction is a significant financial incentive for designers to meet or exceed an agency’s energy reduction requirements for new and existing buildings. Recent tax legislation extended the Energy Efficient Commercial Buildings Deduction, offering a tax deduction of up to $1.80/sf to those investing in energy efficient improvements placed in service after December 31, 2005.

Additional tax breaks for Architects & Designers

Architects and designers who implement energy efficient designs on government buildings are also eligible for the deduction if their design meets the criteria.

Eligible improvements for 179D

Taxpayers that invest in ground up construction or in improvements to their existing buildings are potentially eligible for 179D deductions. Eligible improvements must reduce energy use by making investments in any of the following categories: a building’s envelope, HVAC, and/or interior lighting systems. There are different ways to pursue a deduction and all require comparison to the ASHRAE Standards and certification by a qualified individual.

“KBKG helped us qualify for significantly more tax credits than we would have received. When our initial energy analysis was performed, most of our units did not qualify but were very close. KBKG’s energy consultants worked with our development team and made very cost effective recommendations to increase energy efficiency. After we implemented those suggestions, they found that the majority of our units now qualify, and the benefits are substantial.”

Ideal candidates will generally have improvements with a square footage of at least 50,000 square feet. A wide range of improvements, from simple lighting retrofits to full-scale construction projects, qualify for this timely tax break. Other great candidates include regional or national chains with multiple locations.
