This report consists of a literature review and in-depth interviews with subject matter experts in the Home Performance with ENERGY STAR (HPwES) program area. The goal was to compare Delaware Sustainable Energy Utility (DESEU) HPwES Programs with peer-programs across the United States. The report also identifies key metrics and emerging trends regarding program design.

The catalog is a compilation of state and local energy efficiency potential studies to serve as a resource for energy planners and as a baseline for future analyses.

This report provides a comprehensive review and analysis of home energy upgrade programs with proven track records, focusing on those with robustly verified savings and constituting good examples for replication. This meta-analysis describes program models and implementation strategies for direct install upgrades; heating, HVAC replacement and early retirement; and comprehensive, whole-home upgrades.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

This summary from a Better Buildings Residential Network peer exchange call focused on evaluation, measurement, and verification of predicted/modeled savings from home energy upgrades.

This report is a comprehensive research study of energy efficiency in Northwest residential buildings. It includes a metering study, a single-family report, a manufactured homes report, and a multi-family report. In addition, it includes state-by-state energy use reports, as well as end-use consumption data.

This summary from a Better Buildings Residential Network peer exchange call focused on gathering and communicating loan performance data.

This report provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.

This report describes the effects of utility spending on efficiency programs, how those effects could constitute barriers to investment in energy efficiency, and how policy mechanisms can reduce these barriers.
