This paper investigates the credit enhancement value of NYSERDA's on-bill energy efficiency financing program relative to its similar conventional unsecured loan program. In the raw data, while both loan pools perform well relative to credit card lending, the on-bill loans default more often than the unsecured loans. This paper shows that this result persists: on-bill loans default more often, and this finding is not sensitive to model specification. This paper also shows that NYSERDA's alternate underwriting mechanism based on mortgage and utility bill repayment history performs well, and that projected dollar savings from the installed projects do not significantly influence loan performance.

This report addresses a key bottleneck for private capital: lenders declining to underwrite energy efficiency loans for multifamily housing because they lack confidence in energy savings. It presents findings from an analysis of 230+ buildings, assesses total savings achieved and savings as a percentage of projections, and provides a starting point for an underwriting methodology.

This policy brief describes how NYSERDA's Assisted Home Performance with ENERGY STAR Program increases access to financing through tiered underwriting criteria.
