EPAct EnergyTax Credit Certification


Section 179 D Energy Tax IncentiveEnergy Policy Act of 2005 - (EPAct).                                                      


Our Service Provider is qualified to certify and quantify Energy Efficiency Tax Incentives for owners of commercial property.  You provide building, lighting and/or HVAC specifications. We use Department Of Energy (DOE) approved modeling systems to compare your building's specs to ASHRAE (American Society of Heating Refrigerating and Air-Conditioning Engineers) standards.  Our engineers provide independent certification through on-site Physical Inspections allowing you to claim EPAct Tax Credits.



You may be eligible for a tax deduction of up to $1.80 per square foot for improving the energy efficiency of your existing commercial buildings or designing high efficiency into new buildings.

The Energy Policy Act of 2005 includes a tax benefit for investments in energy-efficient commercial building property designed to significantly reduce the:

  • Heating and Cooling elements
  • Interior lighting energy
  • Building Envelope

Under Section 179 D of the Internal Revenue Code for the proposed or newly installed: lighting upgrades, HVAC, hot water and building envelope, CORE can perform the certification process and conducts this process in accordance to section 1331 of the Energy Policy Act of 2005, Pub. L. No. 109 58,119 Sta. 594 (2005) enacted Section 179 D of the Internal Revenue Code.

Who can benefit from the energy tax deduction?

  • The person or organization that pays for construction is generally the recipient of the deduction. This is usually the building owner, but for some HVAC or lighting efficiency projects, it could be the tenant.
  • Building or renovation must have been put into service after December 31st, 2005.
  • Building must be at least 40,000 sq feet to qualify.


Section 1331 of the Energy Policy Act of 2005 provides for a deduction for energy efficient commercial buildings that reduce annual energy and power consumption by 50% compared to the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) standard. A maximum deduction of $1.80 can be obtained if a reduction in energy consumption reaches 50%.  Additionally, a partial deduction of $0.60 per square foot per "system" is permitted for upgrading one or two major building Sub Systems including Lighting, HVAC, Hot water and Building Envelope.


CORE follows the IRS Guidelines relative to partial deductions and the interim rule, Partial Credits and the Permanent Rule Notice 2006 - 52, Calculations methods - Notice 2006 - 52, and the Certification - Notice 2005 - 52.

Scope of Services

We will conduct a physical inspection and perform an Energy Efficiency Study (EEF) to calculate, determine and certify the allowable deductions for part or all of the cost of Energy Efficient lighting, HVAC, hot water and building envelop or any of these Sub-Systems.


Interim Rules - Lighting:

Interim rules (existing while the Secretary of the Treasury develops long term rules) establishes a deduction of $.30 per square foot for buildings "or portion of buildings" that achieve at least 25% lighting savings relative to the ASHRAE 90.1-2001 lighting power density (Watts per sq ft) requirements (but excluding ASHRAE's ("additional lighting power allowances") and that also uses bi level switching. This deduction increases progressively to $0.60 per square foot for using bi-level switching and achieving 40% lighting savings.


Method of Computation

The performance Rating Method (PRM) must be used to compute the percentage reduction in the total annual energy and power costs with respect to combined usage of a building's heating, cooling, ventilation, hot water and interior lighting systems as compared to the minimum requirements of standard 90.1-2001.


The Energy Efficiency Study (EES) Process:

  • Initial data is gathered to evaluate the potential tax savings for implementation of EES and Certification.
  • Once letter of Engagement is authorized, someone from our engineering team will visit site/ buildings and inspect equipment.
  • Prescribed calculations will be madeon the energy usage and proposed usage utilizing IRS approved software.
  • The calculations, the Certification of approved and qualifying assets/ equipment will be completed and the EES documenting the allowable credits will be delivered to tax payer / property owner.
