![]() Smart controls are digital controls that manage home energy use by communicating with the electric utility, lowering electric bills. Low-global warming potential (GWP) refrigerants.Plug-and-play heating, cooling, and water-heating solutions.Examples of innovations in efficient electrification include: Strategic and targeted efficient equipment upgrades will lower utility bills, driving solutions that lessen household energy burdens. Modular, compact appliances can address installation barriers in smaller housing units and help mitigate costly electrical upgrades. ![]() Thin triple-pane and aerogel-insulated windowsĮfficient electrification will improve the affordability, comfort, and performance of low- to moderate-income homes, Expanding access to air-conditioning in communities that don’t have it.Easy-to-install super-insulated retrofit panels.The Affordable Home Energy Shot is exploring innovative retrofit solutions for affordable multifamily, manufactured, and single-family homes, including: Making building envelope improvements at the same time as health, safety, and structural upgrades can further minimize disruptions for building occupants. Better windows and air sealing can keep outdoor air pollutants from entering the home, improving indoor environmental quality-a particular concern in disadvantaged communities. Panelized insulation and exterior retrofit techniques, which do not require opening up walls, increase the building’s energy efficiency for heating and cooling while also reducing installation time and cost. Energy lost through the building envelope accounts for 70% of the emissions generated locally by our homes. Upgrades to the building envelope-the windows, walls, foundations, and roofs-address the livability and comfort of indoor environments, making for healthier and more resilient homes. DOE’s approach strives to advance scalable technologies and installation solutions for affordable-housing residents while expanding workforce capabilities at the state and local levels. To achieve these goals, DOE is focused on building innovations in three pivotal areas: building upgrades, efficient electrification, and smart controls. Affordable Upgrades to Cut Carbon and Costs In turn, this Energy Earthshot helps ensure that the benefits of the clean energy economy can reach all U.S. With a focus on energy issues within affordable housing, DOE is committed to increasing R&D support in a historically under-resourced sector. The Affordable Home Energy Shot directs DOE’s research and development (R&D) resources and strategy to ensure that households in the greatest need-specifically, the 50 million single-family, multifamily, and manufactured homes rented or owned by households earning less than 80% of the area median income-will benefit from decarbonization solutions. By targeting the design barriers most prevalent in affordable housing, this Energy Earthshot will advance retrofit solutions, leading to more efficient, healthy, and resilient homes. The buildings of the future are here today: 75% of today’s homes will still exist in 2050, making the acceleration of retrofit solutions-new or modified parts or equipment that can be added to existing buildings-the central focus of this Energy Earthshot. Ensuring Equitable and Affordable Solutions Households who report some form of energy insecurity live in homes that are nearly 20% less efficient. These trends disproportionately impact lower-income residents who live in older homes that often lack adequate insulation and energy-efficient appliances. Nearly one in four households nationwide experience high energy burdens as a result, more than 20% fell behind on their energy bills in 2022. The intent of the Affordable Home Energy Shot is to address the persistent burdens faced by low-income households and communities of color.
