What is the Section 179D tax deduction for commercial buildings?

Section 179D provides a tax deduction of up to $5.00 per square foot for energy-efficient commercial building improvements. Under the Inflation Reduction Act, buildings meeting prevailing wage and apprenticeship requirements qualify for the maximum deduction. Qualifying improvements include HVAC, lighting, and building envelope upgrades that reduce energy consumption below ASHRAE 90.1 baseline standards.

Can you stack IRA tax credits with utility rebates?

Yes. IRA tax credits (including 179D deductions), utility rebates, PA Tier II RECs, and demand response payments can be stacked on the same project. Emergent Energy specializes in identifying and coordinating all available incentives simultaneously, often recovering 80–100% of project costs through combined incentive stacking.

IRA Tax Incentives for Commercial Buildings

The Inflation Reduction Act dramatically expanded tax incentives for commercial energy efficiency. Most facilities leave significant money on the table by not claiming them alongside utility rebates.

Utility Rebates + PA RECs + IRA Tax Credits

Stack every available incentive on a single project — most companies only capture 40–60% of what's available.

Key IRA Programs

Three major IRA provisions that apply to commercial and multifamily buildings — each stackable with utility rebates and RECs.

Section 179D — Commercial Buildings

Up to $5.00/sq ft

Federal tax deduction for qualifying commercial building energy efficiency improvements — HVAC, lighting, and building envelope. Applies to new construction and retrofits. Emergent documents qualifying projects and produces the ASHRAE 90.1 baseline energy modeling required by the IRS.

How We Maximize Your Incentives

Most companies work with separate contractors for rebates, tax credits, and RECs. We handle all three in a single, coordinated engagement.

Identify Qualifying Improvements

We identify which efficiency improvements qualify for 179D, IRA credits, and utility rebates simultaneously — ensuring you capture 100% of available incentives, not the industry-average 40–60%.

Energy Modeling & Certification

We produce the energy modeling and certification required by IRS for 179D claims (ASHRAE 90.1 baseline), eliminating the need for separate engineering studies.

Tax Advisor Coordination

We coordinate with your tax advisor to ensure IRA credits are properly claimed alongside rebate submissions — no double-counting, no missed deadlines, no compliance gaps.
