The Energy Efficient Commercial Buildings Tax Deduction (CBTD) is a special financial incentive created by theEnergy Policy Act of 2005 and designed to reduce the initial cost of investing in energy-efficient lighting and other building systems via an accelerated tax deduction.
This special tax deduction allows building owners (or tenants) to write off the complete cost of upgrading a building’s indoor lighting, HVAC/hot water and building envelope in the year the new equipment is placed in service, capped at $1.80/sq.ft. Alternately, the owner (or tenant) could upgrade one of these three systems to earn the CBTD capped at $0.60/sq.ft. In short, with the CBTD, the cost of new lighting or other building systems can be claimed in a single tax year instead of amortized over a period of years.
The CBTD expiration date has been extended twice, most recently by the Energy Independence Act of 2007 (EISA). With this extension, the CBTD can be claimed for qualifying projects completed before January 1, 2014.
