179D for Architects, Engineers & Designers

179D (EPAct) Energy Tax Credits and Savings


There have been a variety of incentives enacted over the past several years, encouraging adoption of energy efficient appliances and other components in building design. One such initiative is section 179D (EPAct) of the Federal Tax Code. This program offers significant tax savings in energy tax credits, intended to offset a portion of the cost associated with energy-efficient components used in construction of new and remodeled, privately owned, commercial buildings.

Significantly, 179D permits architectural firms, designers, and engineers to utilize the same energy tax credits deduction for their work in the building of, remodeling of, or additions to government-owned buildings. This provision is woefully underutilized. Many firms don’t know of the law’s existence, nor do they understand the availability of this substantial tax savings opportunity.

Who qualifies?


Under a special rule, public property, architects, engineers, contractors, environmental consultants, and energy service providers who have worked on energy-efficient projects also qualify for 179D. These projects could include:

  • Schools & State Universities
  • Libraries & Post Offices
  • Municipal parking garage
  • Government Offices & Courthouses
  • Airports & Transportation Facilities
  • Military Bases

Why National Cost?


In order to benefit from the 179D energy rebates, architectural or engineering/design firms must certify the energy-efficiency in the new construction, or remodels of public buildings via a third party.

National Cost can provide a detailed report compiled, validating your firm’s building project’s energy-efficiency compliance.
