What is a Zero Energy Home?
A high performance, energy efficient home that generates
power from the sun for all or most of its annual energy consumption,
resulting in zero net consumption, no energy bills and no carbon emissions.
Zero energy can be achieved by investing in improvements that payback
with energy savings, power sales to the utility and a higher home resale value.

How It Works
A path to zero starts with an assessment to learn about your home,
and identify opportunities to save and generate energy.
Investment Decisions.Select high-impact improvements identified by your energy rating. Receive bids from qualified contractors and find attractive financing, if needed. Compare all the options and get the best deal at a low and affordable cost.
Create Your Plan
Action.Successfully complete the work (usually in 1-2 days) and enjoy living in a better, more comfortable and energy efficient home with lower or zero energy bills. Track your energy conservation, savings and return on investment.
"Now that we've lived in a zero energy home,
we couldn't imagine living anywhere else.
It's so quiet and comfortable. We love our new home."
New Town Homeowner
"Zero energy ready homes are the future of US housing.
They provide a vastly superior experience at a lower ownership cost.
It's an experience that all Americans will want."
Chief Architect for US Department of Energy Building Technologies Office
"In our old house, our heating was oil and pellets.
We paid $1,500 a year for oil, $1,000 for pellets, and electricity was $2,400 a year.
I don’t have any of those bills now. Last year, I got a check from the utility for $700."
Frequently Asked Questions
Can any home become a zero energy home?Nearly every home can be made significantly more energy efficient (20% and up), but the design and building structure of some homes prevents them from achieving the highest levels of efficiency on par with a newly built zero energy home. Also, the size, slope and shading of a roof is sometimes suboptimal for renewable energy. Zero is a long-term goal.
Won’t insulation make my house hot in the summer?Air sealing and insulation actually help a house stay warmer in the winter AND cooler in the summer. In a properly sealed home, it is hard for indoor air to escape and for outdoor air to enter. In the summer, that means that less hot air comes in from outdoors and less air escapes from a cool house. That adds up to a more comfortable home with lower cooling costs.
I know I should do something, but when is optimal?Anytime is good to take steps to conserve energy and save money. Solar qualifies for a 30 percent federal Investment Tax Credit (ITC) until it expires at the end of 2016.

Are energy efficiency improvements worth the cost?The Home Energy Score was designed by the Berkeley Lab and uses building science energy modeling to pinpoint specific changes that will yield savings. The returns can be enhanced by incentives, tax rebates and financing that make improvements attractive investments with immediately lower cash costs, short payback periods and higher home resale values.
Should I get a Home Energy Score before I buy a home?Absolutely. Knowing the energy efficiency of a house and how much energy it consumes is a critical factor to determine the annual operating expenses. Purchasing a home is a great time to plan home improvements because you can likely use your tax-advantaged mortgage financing and make more signficant changes prior to moving in.
Does anyone else have a zero energy home?Yes. The Department of Energy offers an online tour of completed zero energy ready homes across the country, in all climate geographies.
