DOE Tour of Zero: Preston Haven by Thornhill Custom Homes
You are here
Thornhill Custom Homes built this 6,471-square-foot custom home in Dallas, Texas, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
White stucco walls reflect the sun, helping to minimize heat gain.
The double-pane, wood and fiberglass-framed windows have low-e3 coatings to minimize heat transfer into the home in summer or out of the home in winter.
Long-lasting LEDs save energy and require far fewer bulb changes than other types of lighting.
ENERGY STAR appliances and ceiling fans add to energy savings.
A tankless gas water heater supplies endless hot water to the low-flow faucets.
Low-/no-VOC paints and finishes were used throughout the EPA Indoor airPLUS certified home.
Custom-made floor and roof trusses were designed to allow straight runs for HVAC ducts.
A corrugated-plastic ventilated rain screen product was installed over the house wrap to provide a ventilation gap and drainage plane behind the stucco, stone, and timber siding.
The modern design includes a nearly flat roof covered with a highly reflective 60-mil TPO Cool Roof Certified white roofing membrane that minimizes heat gain.

"When we learned it was a Zero Energy Ready Home we felt like it was right for us. We wanted a larger home because we frequently entertain and have out-of-town visitors, but even with the additional space, our energy bills have been much lower than our previous homes.”
