Explore the innovative zHome development during a monthly tour Thursday.
Meet at the Issaquah Highlands construction site — east of the Northeast High Street and Highlands Drive Northeast intersection along High Street — at 3:30 p.m. for the tour. The walkthrough should last until 4:30 p.m. Get directions here.
Because the tour includes the construction site, participants must sign a liability waiver.
Plans call for zHome to include 10 townhouses designed to produce as much electricity as the units consume. By harnessing solar power and using recycled building materials, developers hope the complex causes only minimal impact to the environment.
Crews dug holes for ground-source heat pumps to use subterranean energy to heat the residences. The tour participants should be able to see how the system works.
The construction team has also geared up to pour slabs — a complicated project because of the lines for ground-source heating, photovoltaic conduit and rainwater plumbing.
The project should be completed by next spring.
Dignitaries broke ground on for zHome in late 2008, but the recession delayed construction until April 2010.
The city spearheaded the development of zHome. Howland Development Issaquah — a joint venture of Shoreline developer Howland Homes and Ichijo USA, a subsidiary of Japanese homebuilder Ichijo Co. — handles the construction. Ichijo USA financed the project.
