Tax incentives offered by the Federal government to encourage businesses to increase their energy efficiency are opening the door to great returns on capital investments. One of these incentives is the Energy Efficient Commercial Buildings Tax Deduction (CBTD). This deduction was created by the Energy Policy Act of 2005 and is designed to reduce the initial cost of investing in energy-efficient lighting and other building systems via an accelerated tax deduction.
The CBTD enables building owners (or tenants) to deduct the cost of renovating a building’s interior lighting system, heating, cooling, and hot water systems, and building envelope in the year the new equipment is placed in service, limited to $1.80/sq.ft. The owner (or tenant) could also upgrade one of these three systems and claim the CBTD capped at $0.60/sq.ft. Essentially, utilizing this deduction allows the cost of new lighting or other building systems to be claimed in a single tax year instead of depreciated over a period of years.
Instead of simultaneously retrofitting all three systems, it is often more feasible to focus on upgrading one system. The most profitable investment in energy efficient building systems is lighting. While the area of interior lighting has seen significant cost saving innovations become available over the last decade, the Department of Energy states that 80% of existing commercial buildings continue to operate lighting systems installed before 1986. Considering that lighting represents 40% of the average commercial building’s electric bill, retrofitting these outdated lighting systems can be very profitable. According to the Energy Cost Savings Council, energy-efficient lighting projects generate an average 45% return on investment, paying for themselves in just 2.2 years
Interested in upgrading your lighting or other building system? Be sure to discuss in detail your plans to upgrade your building with your tax advisor, as the CBTD has a number of detailed requirements that must be satisfied before you project even begins.
