Tenant Paying for Energy Audit

[Douglass Belt]

I tried searching the forums for this topic and could not find one, so apologies if this has been asked before and I did not see it....

I have a tenant who wants to pay for an energy audit (Includes installation of CFL lights, water heater blanket wrap, low flow showerheads, improved weather stripping, etc.) In additon, they are doing a blower door test to see where the main areas of heat/cool leaks are in the house. I have no issue with this being done and appreciate my tenant wanting to do this and pay for it themself. The audit results are only sent to the tenant (Since tenant pays utilities) My question is this: After the audit, can the tenant hold that audit results against me to leverage new window installation, or somethiing major? By the way, windows are in good shape. Has anyone dealt with something like this before? I have added insulation in the attic, replaced and repaired storm window's, storm doors, etc., but as all homes have to breathe a little (They have to or it would be dangerous to live there) wondering what limits there are. The home is in great shape and never had an issue with drafts, leaks, and have it will maintained. Any thoughts, advice or experience on this is appreciated!
