New Build home Design
Before you design a new home or remodel an existing one, consider investing in energy efficiency. You'll save energy and money, and your home will be more comfortable and durable. 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 may also want to explore your options for financing an energy-efficient home.
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. To learn more about home energy audits and find free tools and calculators, go to Tips: Your Home's Energy Use, the Residential Services Network, and the Building Performance Institute.
Whole-House Systems Approach
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. In addition to occupant behavior, site conditions, and climate, these include:
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. By taking advantage of local climate and site conditions, designers can often also incorporate passive solar heating and cooling and energy-efficient landscaping strategies. 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.
