This RMI report analyzes the barriers and gaps associated with 'stacking' (combining) federal, state, and local financial incentives for residential clean energy retrofits in the US. It identifies significant complexities in application processes, unclear guidance on the order of funding, and critical funding gaps for health and safety repairs and pre-electrification upgrades. The report provides a framework for program administrators to improve accessibility, particularly for low-income households, to ensure the Inflation Reduction Act (IRA) and other funds effectively drive decarbonization.

This document provides a collection of case studies and resources intended to help State Energy Offices (SEOs) design and implement home energy rebate programs under the Inflation Reduction Act (IRA). It highlights specific tools, frameworks, and programs that address equity, workforce development, consumer education, and supply chain coordination to optimize residential energy retrofits and electrification.

This feasibility study evaluates the potential for implementing EuroPACE, an on-tax financing instrument for residential energy efficiency retrofits, across Belgium, the Netherlands, Portugal, and Spain. The report analyzes market barriers, existing national loan schemes, and case studies of successful programs in France (Oktave), Germany (KfW), and the Netherlands/UK (Energiesprong) to identify scalable models for deep retrofits.

This briefing by the Climate Policy Initiative (CPI) analyzes the economic viability, financial requirements, and energy savings associated with achieving the German government's 2010 Energy Concept targets for residential thermal retrofits. The report focuses on the feasibility of increasing the annual retrofit rate to 2% and the necessity of 'deep' retrofits to meet a target of reducing the building sector's primary energy requirement by 80% by 2050.
