RESNET Board Adopts Revised Procedures for Accredited Software Tools for Residential Energy Efficiency Tax Credits Incorporates Calculation of the Grading the Installation of HVAC Systems

The IRS rules for the 45L federal tax credit for energy-efficient homes recognizes RESNET Publication No. 001 “Procedures for Accrediting Software Tools for Residential Energy Efficiency Tax Credits”.  The U.S. Department of Energy (DOE) has been using the publication for approving software programs for the tax credit and posting their approved programs on the DOE website.

The RESNET Board has adopted an amended version of the publication, RESNET Publication No. 001-20. The amended publication includes the calculations of the new ANSI RESNET/ACCA Standard 310 “Standard for Grading the Installation of HVAC Systems” in calculating compliance to the tax credit.  The publication will credit HVAC systems that have been rated through the new ANSI standard in calculating compliance to the tax credit.

To download the revised publication go to RESNET Publication No. 001-20 

The revised publication involved the vetting of DOE, the National Renewable Energy Laboratory (NREL), the RESNET Standards Development Committee 300’s Calculations Subcommittee and the RESNET Board of Directors Software Consistency Committee.

RESNET Executive Director Steve Baden commented, “The RESNET Board’s action will help ensure that the HVAC systems that are designed and installed properly receive credit for the federal tax credit.  This represents a win for builders and families that are purchasing their homes. A special recognition is due to Philip Fairey of the Florida Solar Energy Center, Eric Werling of DOE, Dave Roberts of NREL, and Jamie Lyons and Mike Moore of Newport Partners. Their assistance was invaluable in the revision of the publication.”

The revised publication has been forwarded to DOE for their adoption.
