“inHabitat” Today, Greenfab was awarded LEED Platinum certification by the USGBC for achievement in green homebuilding and design. Greenfab’s prefabricated, modular home is the first to be certified LEED Platinum in the state of Washington, and it features healthy living spaces, sturdy construction, and a completion rate that is 50% faster than traditional homes built on-site. The home is part of Greenfab’s 1300 Series, which is now available nationwide.InHabitat.com: March the 7th, 2012. Read the full article >>


People often complain about LEED, wondering what is the point of spending all of that money on a plaque. But the real deal with LEED is that it is a third party certification to a tough and evolving standard. That’s why, in a week when the Ideabox IKEA prefab is getting all the media exposure, it is appropriate to get beyond home show hype and look at a real house on a real piece of land. Like this 1300 series from Greenfab, the first to be certified LEED Platinum in the State of Washington. treehugger: March the 7th, 2012. Read the full article >>

Super Models

Modular homes, which have been around for a few hundred years, are adopting an ultra-green identity. A prototype Seattle home offers an unusual gift: graywater recycling. Greenfab’s premier prefab house took three-and-a-half months to build: 14 days in the factory, one day to install, and three months to finish. But the business model was years in the making. The goal: to create a house that is healthier, stronger, and more energy efficient than its stick-built counterparts. “Ours may have a similar sales price to other new homes on the block, but it offers more value in energy efficiencies and innovation,” says Greenfab founder Johnny Hartsfield.

The 1,790-square-foot, three-bedroom house is also extremely efficient. Exterior walls (R-26) are covered in rigid insulation and spray foam. A hybrid water heater supplies hot water, and a mini-split heat pump takes care of heating and cooling. There is also pre-wiring for a 2.4-kW PV system—enough to offset a quarter of the energy use.

Seattle Business Cover

Now, with the economic recovery gathering steam, there has been renewed interest in using prefabricated manufacturing techniques to make modern, green designs more accessible to home buyers. Several new companies are promoting the approach in Washington, among them GreenPod Intelligent Environments in Port Townsend; Seattle-based Greenfab, which installed a seriously efficient modular home in the Central Area in January (expected to achieve LEED Platinum certification); Method Homes, which has a factory in Ferndale; and Seattle-based Ideabuilder. These ventures offer a portfolio of new, green features, such as gray-water recycling, green roofs and heavy-duty insulation. But there is a great deal of skepticism whether they will be able to survive and offer a truly low-cost alternative to custom site-built homes.Seattle Business Magazine September, 2011.

mother nature networks: Modular madness hits Seattle, A super-efficient, three-bedroom prefab home in Seattle installed in only 6 hours as an urban infill project is on track for LEED Platinum certification. A remarkable, super green prefab home recently installed in Seattle has been making waves throughout the Pacific Northwest and the green building community.

Greenfab, Planted in the middle of narrow South Lane Street in Seattle’s Central Area, a 115-foot crane lifted a kitchen module into place on a bare foundation.

The home’s builder, Seattle-based Greenfab, says it’s the first modular home in the city to target the highest level of sustainability certification from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program. LEED raters have been working alongside Greenfab through the designing and building process, and the official certification is expected two months after the home is finished next month.

Crowds gathered Tuesday to watch a house take shape as six modules were craned into place. The house, at 1827 S. Lane St., is the first project by the GreenFab development team. GreenFab is a Seattle-based developer of modular housing. The house is for Rob Humble of HyBrid Architecture, architect on the project, and will be complete in about 45 days. Hybrid Assembly is general contractor. Site excavation began last August, and the demonstration home will be open to the public for a limited time. The 1,790-square-foot, two-level house is made of six modules, three on each level. Modules were delivered by long-haul trucks to the Columbia City Light Rail Station, where they were staged before being trucked two miles to the site to be craned into place.
