179D is a modeled, certified, and documented deduction, not a self-declared one. Here’s what a project has to meet, and what the required study delivers.
Request a Complimentary AnalysisQualification is based on energy-cost savings compared with a reference building meeting the applicable ASHRAE standard. A project must show at least 25% savings to qualify, and the deduction scales upward, point by point, to a maximum at 50% savings. The modeling is done with DOE-approved software by a qualified professional.
The difference between the base and enhanced tiers is labor compliance during construction, and it’s worth roughly five times the deduction.
PWA must be met during construction; it can’t be added after the fact. We confirm whether a project’s documentation supports the enhanced tier.
The deduction must be certified by a licensed engineer or contractor in the jurisdiction where the building is located, who is independent of the taxpayer. Certification includes the energy model, a physical site visit to verify the installed systems, and the documentation that supports the deduction if it’s ever examined.
No. 179D requires certification by a licensed engineer or contractor independent of the taxpayer, that independence is part of what makes it valid.
You’d generally fall to the base tier ($0.58–$1.16 per square foot), which is still worthwhile on a large building. We confirm which tier your documentation supports.
Certification generally includes a physical inspection of the installed systems. It’s a core part of a defensible study.
It varies with building size and documentation, but most studies move quickly once plans, systems data, and any PWA records are in hand.

Section 179D eligibility, amounts, certification, and deadlines depend on the project’s facts and current law, and are determined through the required energy study and certification in coordination with your tax advisor.
