IDAP Incentives
• Design Incentive - $5,000 + $0.10/sf
(paid at the end of design)
• Construction Incentive – 2 years modeled energy cost
savings (paid at end of construction)
• Optional Performance Award – 1 year actual energy
cost savings (paid after 12 months of occupancy,
monitored)

*ASHRAE 90.1 – 2013
** 10% savings from code
Baseline Building Performance
BBP = BBUEC + (BPFCode x BBREC)
BBP = Baseline Building Performance, annual energy
cost of Baseline Building (unregulated + regulated cost)
BBUEC = Baseline Building Unregulated Energy Cost.
From Baseline model
BPFCode = Building Performance Factor (BPF) of a
building meeting the City building code (2015 IECC,
represented by ASHRAE 90.1 – 2013)
BBREC = Baseline Building Regulated Energy Cost,
from Baseline Appendix G model.
7
Proposed Building Target
PBPt = BBUEC + (BPFIDAP x BBREC)
PBPt = Proposed Building Performance energy cost
target, the maximum total energy cost of Proposed
Building (unregulated + regulated cost). Unregulated
energy cost will be the same in the proposed and
baseline.
BPFIDAP = IDAP BPF, represents 10% savings from
current code
8
Construction Incentive
Construction Incentive = 2 x (BBP – PBPm)
PBPm = Modeled energy cost of proposed building
PBPm must be ≤ PBPt
9
Modeled Energy Cost Savings
Optional Performance Incentive
Optional Performance Incentive =
(BPFCode x BBREC) – Actual Regulated Energy Cost
