The Residential Energy Efficiency and Demand Response tool (REEDR), is an EnergyPlus-based simulation tool that has been developed with funding from the RTF. The RTF is calibrating REEDR-generated EnergyPlus models to best available Northwest data sources, including the first and second Residential Building Stock Assessments (RBSAs) and homes from the End Use Load Research (EULR) Home Energy Metering Study (HEMS). The scope of this committee is to review calibrations proposed by the RTF Contract Analyst Team (CAT), provide input and recommendations to the RTF CAT for improving calibrations, and make a final recommendation regarding calibrations to the RTF.
