Currently, the Federal Government offers the Commercial Building Energy Efficiency Tax Deduction (also known as the 179D Tax Deduction). Congress approves this incentive every few years during the federal budget approval process. For lighting measures, this incentive currently provides a federal income tax deduction up to a $0.60 per square foot for buildings that achieve a 50% or greater reduction in lighting power density over national standards.  Achieving this incentive takes a very intensive survey and documentation of the installed, energy efficient lighting system. ENLIGHTEN has successfully managed and helped clients achieve this incentive in the past. This tax deduction is set to expire at the end of this year 2020. Often Congress re-approves this measure retroactively.
