This document outlines a project to establish savings algorithms and evaluation procedures for emerging technologies and innovative energy efficiency programs. It identifies knowledge gaps for technologies like ductless heat pumps, LED lighting, heat pump water heaters, advanced power strips, and biomass boilers. It recommends next steps like monitoring ductless heat pump installations to verify performance in cold weather and surveying residential advanced power strip purchasers. The overall goal is to close knowledge gaps and develop standardized protocols for calculating savings from these emerging approaches.
