Energy credit for windows

[Kea]

Client installed new windows and a door last year & has sent me the Energy Star stickers. They included little outline maps of the US that says they are Energy Star Qualified in the shaded areas. They look to me like the whole map is shaded, but there are a few white streaks. Not sure if those are areas where they are not qualified or if it's just bad printing.

If they are non-qualifying areas, how can I tell "exactly" what areas are excluded? Map is small & not very detailed.

When I've done the energy credits for the central air conditioning units, the client had a specific form from the manufacturer that stated that unit qualified for the IRS tax credit.

Does the manufacturer have a web site? I have found maps online that you can blow up bigger.

The taxpayer must have a certificate from the manufacturer stating that this produce qualifies for the energy tax credit. Energy star rated is not enough.
