[Equest-users] Tax incentive

Hi eQuester:

I know eQuest is qualified software for calculating Commercial Building Tax
Deductions. eQuest use a standard Title 24. Tax Deductions is based on
ASHARE 90.1 for commercial buildings.

My question is how to compare a baseline model (actual situation) to ASHARE
90.1 in the eQuest?

Any suggestion and guidance are welcomed.
