HVAC 4 Deemed Measures Uncertainty Year 2 Report

This study set out to advance the understanding of the uncertainty associated with ex ante energy savings in California by estimating the corresponding standard deviations for a few key HVAC measures. This report provides the methodology developed by the team as well as the results from the second year of this study. The measures studied include three that are not captured by the separate (but related) impact evaluations of the Quality Installation, Quality Maintenance, or the upstream HVAC programs: residential furnaces, nonresidential boilers, and VFDs at nonresidential HVAC fans. By using Monte Carlo simulations, DEER prototype eQUEST models, and data gathered through various studies, the uncertainty around the ex ante savings for a single building type within a single climate zone was estimated for each measure. In addition, the input parameters that were the leading drivers of the uncertainty for the ex ante savings associated with each of the studied measure cases were determined and reported. Finally, the report provides recommendations for further study that might be performed through relevant evaluations or additional data collection efforts.
