If a project doesn't reduce energy costs enough to qualify for that deduction, there are deductions of up to $0.60 per square foot each for lighting, HVAC and the building envelope. Government buildings, which don't pay taxes, may transfer tax deductions to project designers. To qualify for a deduction, an HVAC project must reduce energy costs at least 16.67 percent below the costs for a building designed to meet ASHRAE 90.1-2001. The project must use energy modeling to show the energy cost savings.
