Straw bale buildings were fairly common in the United States between 18, but it wasn't until the mid- to late-1990s that building codes began to acknowledge them as a viable approach.

If you live in or are planning to buy an earth-sheltered, straw bale, log, or manufactured home, below is more information and links with suggestions to help improve your home’s energy efficiency: Efficient Earth-Sheltered HomesĮarth-sheltered homes can be built underground or bermed, and-when well designed and built-can be comfortable, durable, and energy-efficient. Earth-Sheltered, Straw Bale, Log, and Manufactured Homes Passive solar home design takes advantage of climatic and site conditions to provide heating in the winter and cooling in the summer. Cool RoofsĬool roofs use highly reflective materials to reflect more light and absorb less heat from sunlight, which keeps homes cooler during hot weather. If you’re building a new house or adding on to an existing one, consider using advanced house framing (also known as optimum value engineering), which reduces lumber use and waste and improves energy efficiency in a wood-framed house. The intent is to reduce home energy use as cost-effectively as possible, and then meet the reduced load with on-site renewable energy systems. By taking advantage of local climate and site conditions, designers can often also incorporate passive solar heating and cooling and energy-efficient landscaping strategies. Ultra-efficient homes combine state-of-the-art energy-efficient construction, appliances, and lighting with commercially available renewable energy systems, such as solar water heating and solar electricity.

Recommendations show how to improve the energy efficiency of the home to achieve a higher score and save money. The Home Facts provide details about the current structure and systems. The Score reflects the energy efficiency of a home based on the home's structure and heating, cooling, and hot water systems. Department of Energy, which provides a rating of your home's current efficiency, as well as a list of improvements and potential savings. The Home Energy Score is a national rating system, developed by the U.S. In addition to how you use energy, the conditions of where your home is situated, and the local climate, these include:īefore making upgrades, you may also want to work with an energy assessor to use the Home Energy Score. If you plan to design and build a new home or do an extensive remodel on an existing house, optimizing home energy efficiency requires a whole-house systems approach to ensure that you and your team of building professionals consider all the variables, details, and interactions that affect energy use in your home.

To learn more about home energy assessments and find free tools and calculators, go to Your Home's Energy Use, the Residential Services Network, and the Building Performance Institute. In an existing house, the first step is to conduct a home energy assessment (sometimes referred to as an energy audit) to find out how your home uses energy and determine the best ways to cut energy use and costs. You may also want to explore your options for financing an energy-efficient home.

The planning process is also a good time to look into a renewable energy system that can provide electricity, water heating, or space heating and cooling. You'll save energy and money, and your home will be more comfortable and durable.

Before you design a new home or remodel an existing one, consider investing in energy efficiency.
