DOE Tour of Zero: Revive Lotus Townhome by Philgreen Construction

Philgreen Construction built this 1,434-square-foot multifamily project in Fort Collins, Colorado, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.

The simple shed roofs allowed Philgreen to install up to 5.46 kW of solar panels on the roofs of these townhomes.

Coated OSB wall sheathing with taped seams replaced house wrap as the continuous drainage plane and air barrier behind the siding.

Vinyl-framed, double-pane windows let in light and keep in heat.

ENERGY STAR appliances add to energy savings.

The advanced technology LED lighting and ENERGY STAR ceiling fans use less energy and generate less heat than traditional lighting products.

A compact plumbing design helps hot water from the heat pump water heater quickly reach its destination.

A 3.6 COP/18.1 EER ground-source heat pump efficiently heats and cools the townhome.

Staggered studs in the walls allow room for insulation to wrap around the edges of the studs preventing heat transfer through the walls.
