Energy/Green Building Incentives

Are you taking advantage of every green building incentive available for your property?


Over the past several years, Congress and recent administrations have placed a much emphasis on green building and energy independence initiatives—and none have been more valuable to designers and builders than the Energy-Efficient Commercial Building Deduction (more commonly known as section 179D of the tax code).

Building owners, architects, contractors and designers can now qualify for up to $1.80 per square foot for installing energy efficient lighting, heating and cooling systems and building envelope.

who can qualify:

  • Retail buildings
  • Office buildings
  • Industrial buildings
  • Apartment buildings (at least 4 stories)
  • Government Buildings
  • Warehouses

Section 45L Tax Credit

Recent tax legislation extended the Energy Efficient Home Credit which offers a 45L Tax Credit of $2,000 per dwelling unit to developers of energy efficient homes and apartment buildings.

Eligible 45L Tax Credit Apartment Buildings & Condos: A dwelling unit should provide a level of heating and cooling energy consumption that is significantly less than certain national energy standards, dependent on when the unit is sold or leased. Based on current construction trends, many developments already exceed these standards. All residential developments and apartment buildings completed within the last 4 years are worth assessing for potential 45L tax credits. Eligible construction also includes substantial reconstruction and rehabilitation. Homebuilders and developers can still claim the 45L tax credit retroactively if they did not claim them on previous tax returns.


  • Properties must be three stories or lower.
  • Must incorporate energy efficient features such as high R-Value insulation and roofing, windows, doors, and/or HVAC systems.

Who can benefit?

  • Homebuilders
  • Multifamily Developers

The following types of projects should be considered:

  • Affordable housing
  • Apartment buildings
  • Assisted living housing
  • Production home developments
  • Residential condominiums
  • Student housing
  • Substantial reconstruction or rehabilitation

The Process

The basis for developing and supporting the 45L tax credit is a detailed energy analysis that must be certified by a qualified third-party. Our multi-disciplinary team of engineers and tax experts will ensure that you obtain the maximum tax credits and provide all the documentation necessary to sustain an IRS audit. We use IRS approved software programs for the IRC Sec. 45L certification.


Approximately 75% of businesses are overcharged on their utility services each year, adding up to billions of dollars in potential refunds, credits, and on-going monthly savings.

As a part of CORE’s comprehensive energy and green buildings services, we provide a zero-cost audit review that will identify all overcharges. We then provide all of the necessary documentation to the state and local utility companies necessary so that your company can receive refunds or credits as well as ongoing monthly savings from our work.

services we would want to review:

  • GAS

Again, this is a complimentary service, and we only get paid if we provide your company with a refund, credit or on-going savings. Additionally, since a business can file for refunds going back 4 years in most states, we are confident that we can help your organization find real savings.

CORE's SMART Building Program helps Property Owners pay for needed upgrades

Due to the passing of favorable tax laws, a business or commercial building owner can now receive lucrative tax incentives when replacing or retrofitting lighting, HVAC equipment and roofing systems. Under the new disposition tax laws, a company can now take a 100% tax deduction on qualified property when being abandoned or disposed of in the current tax year.

CORE will provide all the necessary engineering calculations and documentation required for your property to claim all of this additional depreciation. This hidden treasure can quickly add-up to hundreds of thousands of dollars in new found money that will literally pay for the newly-installed energy efficient technologies.
