Eco 3 Greenfill

    • BrightLeaf Homes built this 4,608-square-foot home in Brookfield, Illinois, to the performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
    • Beneath the rot-resistant fiber cement siding, a multilayered system of coated OSB sheathing, carefully layered and taped house wrap, and flexible tape flashing around doors, windows, and openings provides comprehensive protection against air and water leaks.
    • About half of the basement is above grade, allowing for plenty of daylight to enter the 36-inch-tall basement windows on both sides of the house.
    • Although packed with modern efficiency features, the BrightLeaf home's traditional "prairie-cottage" style fits in with the established neighborhood's older homes.
    • Nearly all of the home's lighting is provided by ultra-efficient light emitting diode (LED) lamps.
    • The home has an ENERGY STAR dishwasher and laundry equipment for energy and water savings.
    • High-efficiency, triple-pane, vinyl-framed windows are much more efficient than standard windows.
    • A single plumbing wall on the second floor provides access for pipes to both bathrooms and the laundry room to limit the distance that hot water needs to travel.
    • All hot water lines are completely insulated to retain heat longer and minimize the amount of wasted water down the drain while waiting for hot water.
    • The home meets the requirements of the U.S. Environmental Protection Agency's Indoor airPLUS certification, including using structural wood products, primer, paint, cabinets, and flooring that emit few or no air contaminants.

      Home owner (or occupant) Testimony
      We thoroughly enjoy living in our BrightLeaf home. The energy efficiency, open floor plan, passive solar heat, and light are all great features. Energy bills are less than half of our previous home with 20% more square footage. Friends and neighbors always comment on the beauty of the space.
