摘要

For decades both electric and fuel-based energy efficiency programs targeting thernmultifamily residential sector have been deployed across the country. Despite the long history ofrnprograms and their evaluations, there is a dearth of multifamily post-construction billing analysisrnavailable. As cash flows from energy savings are beginning to play a crucial role in therndevelopment of financing mechanisms (including PACE, on bill recovery) and underwritingrncriteria, post-construction billing data is of paramount importance. This paper examines a billingrnanalysis conducted on all of the projects that completed NYSERDA’s Multifamily PerformancernProgram as of the writing of this paper. The sample includes 93 buildings with over 3,600 unitsrnof housing, representing more than 3.4 Million square feet of space. The common process andrnstrict quality control shared by each of these projects, coupled with the billing analysis, giverninsight into the accuracy of modeled savings and the impact of heating system type and buildingrnheight on savings realization. An examination of the outliers contained in this dataset gives risernto important lessons regarding the negative impact of take-back and unanticipated load growthrnon the success of efficiency projects, which all underwriters and administrators shouldrnunderstand when relying on predicted savings to guide financial decision making. ThernMultifamily Performance Program challenged buildings owners to reduce their buildings’rnconsumption by 20%. The observed average energy savings per project was 19.7%, which thernauthors interpret as a successful program outcome. Projects in MPP tended to over-predictrnelectric savings and under-predict fuel savings.
