I had a new vapor barrier installed in crawl space. Does this qualify for the tax credit?

This does not seem to fit the criteria required for the energy efficient home improvement credit. 

 

Qualified energy efficiency improvements.

Qualified energy efficiency improvements are the following building envelope components installed on or in your main home that you owned during 2023 located in the United States if the original use of the component begins with you, the component can be expected to remain in use at least 5 years, and the component meets certain energy standards.

• Any insulation material or system and air sealing material or system that is specifically and primarily designed to reduce heat loss or gain of a home when installed in or on such a home.
• Exterior windows and skylights.
• Exterior doors.

For purposes of figuring the credit, don't include amounts paid for the onsite preparation, assembly, or original installation of the building envelope component.

• Instructions -Energy Credits

You could check your state to see if they have a special credit.
