Q: Did this stimulus bill do anything for commercial buildings?

A: There are significant appropriations and potential for funding for energy efficiency improvements to government buildings, public housing, and schools in this stimulus bill, but standard commercial buildings were already offered a tax credit of up to $1.80/sq ft for energy efficiency improvements that reduce heating and cooling energy consumption by at least 50% as part of the 2008 "bailout bill". There is also a $.60/sq ft tax credit available for smaller efficiency improvements to commercial buildings. You can find more detail about these commercial credits here.
