Karuna House, a single family residence which stands on the hilltops of Yamhill County, Oregon has received the Passive House (PHUIS+), Minergie-P-ECO and LEED for Homes Platinum certifications. It is the only house in the world to receive all these hallmark certifications of green building. The house was designed by Holst Architecture and built by the company Hammer & Hand.
The innovative company Ecovative recently “grew” their first tiny house. Or more precisely, after putting together the pine walls of the tiny house, they filled it with the so-called Mushroom Insulation. This insulation proceeded to literally grow in place inside the wall cavities, which already contained all the wiring and plumbing. In this way, the insulation actually glued together the pine boards used to build the framework of the house. The house measures around 62 square feet and is mounted on a trailer so it can be transported anywhere. The tiny house is a prototype and a test of Ecovative’s Mushroom Insulation and they are currently touring the country showing their creation.
The Colorado-based Formworks Building Inc. has been specializing in earth sheltered building technology since 1979. The main idea behind their buildings is the creation of sustainable, affordable housing. Formworks structures have an estimated usable life span of over one hundred years without any major maintenance. These houses are built into the earth surrounding the building site, which has the added bonus of protecting the home from raging storms, tornadoes, hurricanes, fires, mudslides and so on.
