DOE Tour of Zero: 5th Street Deep Rehab by Carl Franklin Homes & Green Extreme Homes
You are here
Carl Franklin Homes renovated this 1,108-square-foot home in Garland, Texas, to the performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
This home was gutted down to the studs, partially reframed, and completely re-sided as part of an ultra-efficient deep energy retrofit.
Ceiling fans help occupants feel more comfortable with less use of an air conditioner.
The home meets the requirements of the U.S. Environmental Protection Agency’s Indoor airPLUS certification, including the use of structural wood products, primer, paint, cabinets, and flooring that emit no or few air contaminants.
The home was equipped with a high-efficiency ENERGY STAR refrigerator, dishwasher, and laundry equipment for energy and water savings.
The water heater was centrally located so that no water-using appliance was farther away than 15 feet. Short pipe runs mean that less hot water is lost waiting for it to warm up.
All bath fixtures were EPA WaterSense-rated for water efficiency.
A high-efficiency ductless heat pump provides both heating and cooling. The heat pump has a Heating Season Performance Factor (HPSF) of 9.1 and a cooling efficiency Seasonal Energy Efficiency Ratio (SEER) of 20.
An old addition, which had a wooden foundation that had extensive water damage, was removed and replaced with a new addition with a correctly poured concrete slab foundation.
Blown-in fiberglass wall insulation, ultra-efficient windows, and air-sealing helped to ensure a continuous thermal blanket and comprehensive draft protection.
Eight inches of closed-cell spray foam covered the underside of the roof deck to create an insulated nonvented attic.
With the old drywall removed, fiberglass insulation was blown in to fill the wall cavities. Rigid foam was installed over the studs to create a continuous thermal blanket around the house.
