August 24, 2006

COMcheck, a software tool developed by DOE, can now be used to assist commercial building owners demonstrate compliance with building energy codes.  The Internal Revenue Service (IRS) has agreed that the software can be used to help determine eligibility for lighting tax credits by calculating the percentage reduction in a project's lighting power density (LPD) compared to a code building as defined by Standard 90.1-2001. This helps owners plan improvements and claim credit as these interim rules permit. 

Owners can qualify for a tax credit between 30 and 60 cents per square foot off the cost of purchasing an energy efficient lighting system.  The full range of credits will be available when the IRS finishes its final rules.  The COMcheck tool is available for download at; a web-based version is also available.
