DOE Tour of Zero: Cobbler Lane by Addison Homes
You are here
Addison Homes built this 4,530-square-foot home in Simpsonville, South Carolina, to the performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
In addition to being certified to the DOE Zero Energy Ready Home program, the home also achieved a National Association of Home Builders National Green Building Standard emerald level designation.
Advanced technology is used throughout the home including ENERGY STAR-certified LED and compact fluorescent lighting, appliances, and ceiling fans.
An ENERGY STAR-rated high-efficiency refrigerator and dishwasher add to energy and water savings.
Energy and water use are reduced with low-flow plumbing fixtures and demand-controlled recirculation loops on the hot water lines.
The home’s fresh air system utilizes an outdoor air intake that is ducted to the return side of the heat pump air handler through a high-capture filter. Even when the heat pump is not needed for heating or cooling, advanced controls ensure adequate fresh air flow.
Timer-controlled bath fans remove excess moisture after showering.
The high-efficiency windows include invisible advanced coatings that let in visible light while minimizing unwanted heat gain and loss.
Advanced controls can help improve the efficiency of the home’s indoor comfort system.
Two highly efficient endless hot water heaters ensure hot water is always available throughout the home.
The foil-faced roof sheathing provides a sun barrier that keeps the attic significantly cooler in summer.
The professionally installed interior comfort delivery system includes an air-source heat pump and ducts that are located between floors and in an insulated crawl space.
The sealed, insulated crawlspace is a clean, dry location to house the main floor heating ducts and also provides bonus storage space.

“Living in a certified Zero Energy Ready Home has exceeded our expectations for energy efficiency, air quality, and comfort – plus, it’s a lovely place we are happy to call home! Our utility bills are significantly lower than before, even though we have 44% more space. In fact, while our old 2,500-square-foot house was on the market – and vacant – the electric bill was 20% higher than what we paid at the same time in our new – and occupied – 4,500-square-foot home. Isn’t that remarkable? So while our power bill is lower, our comfort, our well-being, and our quality of life are all much, much higher.”
