Abstract

The current body of knowledge related to measure cost development and estimation in regulatory and program design applications is small, especially compared to that for estimating measure impacts, and innovations have lagged. In this paper, we draw upon our experience conducting measure cost studies in California and investigating ex ante measure cost values used in other jurisdictions across the United States to frame the primary regulatory and program planning needs related to ex ante measure costs. We then provide a comprehensive overview of the key analytic and data collection challenges in the context of those needs, including tradeoffs between measure granularity and data requirements, equipment price forecasting, dual baselines, interactions with codes and standards, and estimating incremental measures costs for custom and new construction programs. Finally, we present examples of emerging data collection and analysis approaches that address some of these challenges and provide a roadmap for measure cost research and data development going forward.
