Good afternoon.  The energy reducing project you completed may very well be eligible for additional tax deductions allowable under the EPAct - Energy Tax Incentive Act of 2005.  This program deduction allows for up to $1.80 per sq ft  ($0.25 - $1.80) based on the type of energy reducing project and meeting / exceeding ASHRAE 2001 Energy Code standards; Lighting and lighting controls - up to $0.60 sq/ft, HVAC - up to $0.60 sq/ft, and the Buiding's envelope up to $0.60 sq/ft. 

The IRS requires a study be completed by specifically trained engineers in order to meet IRS and ASHRAE compliance standards. 

Please feel free to reach out to us for a complimentary feasibilty study which will indicate the expected deduction and the cost of completing the study.
