ZERO ENERGY Homes

On Your Lot or Ours

Sunroc Builders has partnered with the Department of Energy (DOE) to build Zero Energy Homes in Sarasota and Bradenton, Florida.
A Zero Energy home will produce the energy equal to the amount it consumes in a year. This is based on 4 Adults in a 3 Bedroom House, for example. Our Zero Energy Homes are still connected to the grid, in order to have a consistent supply of power. When excess power is generated by the home, it is fed into the grid. When not enough power is generated, the grid will supply the needed power. Overall, the system is designed to consume "Net" Zero Energy each year.
In addition to the energy efficiency, there are many more advantages of a DOE Certified Zero Energy Certified Home:

  • Lower environmental impact
  • Locked in Energy Price - No more Electricity Increases!
  • Improved indoor air quality and overall comfort
  • Higher Resale Value
  • Efficient water & hot water
  • Lower Cost of Ownership due to More Durable Construction Techniques
  • ENERGY STAR Appliances & Lighting
  • 3rd Party inspections

  • All of these benefits add up to home that is More Efficient, More Comfortable, More Durable and More Advanced than any other home available today.

    Zero Energy Home Plans:

    There are many home plans that are designed to be extremely energy efficient, located at EnergySmartHomePlans.com. Also, most standard home plans can be converted to a Zero Energy Home, during the Pre-Planning stage.

    A ZERO ENERGY Sunroc Builders Home has the following features:


    Solar Electric (PV) System

    Solar Electric (PV) System

  • Sized to Provide 100% of the Power Needed (For example, 4 adults in a 3 bedroom house)
  • PV (Photovoltaic) Electric Panels with 25-year warranty
  • AC/DC Inverter with 10-year warranty
  • Grid Tied - Your Utility will provide electicity when you need it, and give you credit when you generate excess
  • Building/Array Site Assessment (Shading Study, Array Location & Inclination)
  • Structural and Safety Considerations (Upgraded Trusses, Fall Protection)
  • Homeowner Education (RERH Checklist, Documentation of items above)
  • Lakeland Zero Energy Certified Homes

    HERS Ratings:

    HERS Ratings are performed by third party RESNET Certifiers to verify the construction quality and rate the energy useage of a new home. A home built to standard code is 100. An ENERGY STAR home is around 85. A SUNROC Builder's ZERO ENERGY Home is Zero or less.

  • Click here for a Pre Annual Energy Summary for a NET Zero Energy Home.
  • Click here for Pre Annual Energy Summary for a Zero Energy READY Home.
    The HERS rater performs a blower door test, duct leakage test, measures air flows, and verifies construction practices and materials throughout the construction process, giving you piece of mind that the home is built to the highest standards.

  • Low Environmental Impact

    Low Environmental Impact


    To reduce the environmental impact of a Sunroc Builders Zero Energy Home, the environment is considered before, during and after construction.
    Before Construction, materials are selected based on environmental impact such as location and manufacturing techniques.
    During Construction, Low or No VOC construction materials are used, construction materials are minimized and/or recycled, and employees are trained in low environmental impact techniques.
    After Construction, By Generating 100% of the power needed for the home with PV, the environmental impact from one of our homes is minimal.
    Below is the Emissions Summary Calculated by the "Energy Gauge" Program developed by UCF's Florida Solar Energy Center, for a Sunroc Builders Zero Energy Home: (Click here for the full report)
  • SO2 = -0.84 Lbs
  • NOX = -0.39 Lbs
  • CO = -0.23 Tons
