During this quarter, the RTF expanded the measure portfolio by adding the Efficient Portable Electric Spas UES and deactivated some applications in the Residential Lighting UES. These deactivations were celebrated as they represent the significant accomplishments in past residential lighting programs. In addition, the RTF looked ahead to 2024 by discussing the RTF 2024 Work Plan and adding performance metrics to the residential HVAC measures to support programs offering air conditioning and heat pump measures next year. Please reach out to Laura Thomas with any questions.

The RTF spent the second quarter of 2023 primarily focused on considering updates to existing measures, approving changes to nine UES measures. These measures covered a broad range of technologies from pumps to thermostatic shower restriction values to the majority of the RTF's suite of weatherization measures. The RTF also reviewed the completion of the first calibration task of the new Residential Energy Efficiency and Demand Response (REEDR) tool. Two of the non-measure specific subcommittees, the Implementers Group and Small and Rural Utilities, also convened this quarterly to discuss recent RTF decisions and share member priorities.

Every June the RTF publishes an annual report enumerating its accomplishments over the course of the previous year. In 2022, the RTF continued its central work of developing and maintaining conservation measures, including expanding the suite of heat pumps water heaters, creating a standard protocol for demand control kitchen ventilation, as well as improving on existing measures including residential lighting.

The RTF had a busy start to 2023 updating three UES measures and one standard protocol, deactivating one UES measure, and adding two new measures to the portfolio. In addition, the RTF reviewed the results of a number of studies and projects completed last year, including explorations on the impacts of low global warming potential (GWP) refrigerants on energy efficiency, methodology to value building resilience, and a framework for assessing energy efficiency and demand response wholistically. The RTF also advanced the development and maintenance of its commercial and residential models and completed commercial model alignment for a number of building …

With the last quarter of the year, the RTF was able to accomplish a great deal to wrap up 2022. Members adopted updates to two existing UES measures, Green Motor Rewind and Non-Residential Midstream Lighting. The RTF tackled some challenging non measure work, including providing insights on how to advance commercial whole building performance-based approaches and identifying a path forward for considering dual fuel heat pumps. Members provided valuable perspective on important measure updates, particularly Weatherization and Air Source Heat Pumps for single family and manufactured homes, providing additional time to dig into key aspects of these measures for updates …
