The tax deduction may be claimed by:
- Owners or Tenants of commercial buildings of any height
- Owners of multifamily buildings over 4 stories

What Systems Qualify?
- Building Envelope

To qualify, the total building energy and power costs must be at least 50% below a comparable building that meets ASHRAE 90.1-2007 standards.
Energy modeling is required to justify the deduction. Improvements must be inspected and tested by a qualified engineer. Partner Energy engineers use IRS-approved software to model the energy consumption of your building to determine whether the completed improvements meet the minimum requirements to qualify.
