DOE Tour of Zero: Urban Prairie Street by Revive Properties / Philgreen Construction
You are here
Revive Properties and Philgreen Construction built this 1,620-square-foot production home in Fort Collins, Colorado, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
Beneath the fiber cement and stone siding, the exterior walls are filled with blown cellulose.
All of the homes in the development feature rooftop solar panels, ground source heat pumps, and staggered-stud wall construction.
ENERGY STAR appliances and EPA WaterSense-labeled plumbing fixtures add to energy and water savings.
LED lighting and ENERGY STAR ceiling fans supplement the natural light.
High-efficiency double-pane windows provide daylight to nearly every room.
Spray foam and rigid foam were used under the slabs while rigid foam wraps the exterior of the foundation walls.
Rim joists were insulated with R-20 of open-cell spray foam.
The underside of the roof deck was insulated with R-50 of open-cell spray foam, providing a conditioned space for the HVAC ducts. Heating and cooling is provided by a 3.6-COP ground-source heat pump.
Extensive caulking and spray foam in the attic and at rim joists helped the building achieve draft-free (1.3 ACH 50) construction.

“When I walk into the house it smells like fresh air. So, even though it is maintaining an even temperature with little energy use, the air replacement is sufficient to keep a fresh-air feel. I am so proud of this home.”
