The question this answers is narrow, and it is the only one that matters at screening: does substituting C-PACE for a portion of the subordinate tier improve the blended cost of capital and the equity requirement on this specific deal? Run it twice, conventional and with the assessment, and compare six metrics. If blended cost does not improve, the mechanism is not right for this project, and the worksheet says so. Includes the note on costing the equity tier — costing it at zero is the single most common error and understates the case — the three effects to expect plus the fourth that often decides it for merchant builders, four counterweights to price before deciding, and a five-test decision block.
