What is the tax deduction amount?
The deduction is equal to energy-efficient commercial building property expenditures made by the taxpayer, subject to a cap. The deduction is limited to an amount equal to $1.80 per square foot of the property for which such expenditures are made. The deduction is allowed in the year in which the property is placed in service. For tax purposes, “placed in service” generally means the time at which the property is ready for its intended use.
