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. With less of this temperature stratification during the winter months, you’ll even find yourself comfortable at a lower thermostat setting than you’re used to.īefore making major efficiency improvements to your house, find out from a pro where and why energy is being wasted and what you should do about it by getting an energy audit.The intent of the Affordable Home Energy Shot is to address the persistent burdens faced by low-income households and communities of color. No more cold drafts at your feet while temperatures at head level are a sweaty 80☏. If you live in a warm climate with high cooling requirements, it makes a lot of sense to tighten up the house to reduce your cooling load before investing in new air conditioning equipment.Ī tight, well-insulated house saves energy and allows you to get by with smaller capacity heating and air conditioning systems, and it is also more comfortable, with smaller temperature swings. The same arguments hold true with air conditioning. By reducing your heating needs, you may increase comfort and you may be able to get by with a significantly smaller - and less expensive - furnace or boiler. You should first try to lower your heating requirements. Replacing your existing heating system with one that’s more efficient may well be a wise step, but it shouldn’t necessarily be your first step. So should you rush right out and buy a new super-efficient one? Not necessarily. Your old furnace or boiler chugs away burning gas or oil like there’s no tomorrow.

If you live in a cold climate, you probably spend something like half of your energy dollars on heat.
