What Is R-Value? Simply put, R-value is a measurement of how insulating a building material is, protecting one side from the heat or cold on the other side. A higher R-value means that a material insulates better than one with a lower value. In order to get an idea of what these values are, here […]
A new company in Portland, Oregon is gearing up to manufacture large quantities of the latest product in the ICF (insulated concrete forms) world. BluBloc offers a twist on standard ICF products – it uses recycled styrofoam instead of manufacturing new for use in the forms. BluBloc is 85% recycled polystyrene foam (styrofoam) and 15% […]
Researchers at the University of Sydney are using discarded macadamia nut shells to make 3D printed microtimber for specialized exterior uses.
Rammed earth is cheap, tough and green and has been around for centuries. But modern architects are just rediscovering its many uses in construction.
Something very unique has happened in Arkansas! The Eco Center at Ferncliff in Little Rock is a volunteer-built straw bale mecca for those looking for sustainable building options. The floors alone are worthy of an article to themselves! First, a bit of background. Ferncliff is a summer camp and conference center owned by a nearby […]
Lowe’s Innovation Labs is now offering 3-D printing of household hardware items from a Lowe’s-owned Orchard Supply Store in Mountain View, California.

A new study shows that straw bale buildings are carbon neutral. The analysis looked at the cost of growing the straw to the buildings end of useful life.
Spray foam insulation can help save up to 50% in energy costs, protect a building from moisture intrusion, and provide sound insulation. In addition, it provides two to three times more insulation that traditional fiberglass. However, according to Environmental Working Group, most common spray polyurethane foam insulation contains methylene diphenyl diisocyanate, or MDI, a synthetic chemical […]
Titan Brick is made of 90% dirt waterproofed with non-toxic chemicals. It features R-20 insulating power plus superior strength compared to concrete blocks.
In a story that gained national attention last week, it was revealed that certain low-cost Chinese-made laminate flooring products sold by Lumber Liquidators contain a high volume of formaldehyde.

The 210,000 square foot office building is causing a bit of an […]
The Bullitt Center in Seattle, Washington, is one of the most self-sufficient buildings on the planet. It is net zero energy and, after the water reuse system is approved by city authorities, net zero water. Net zero means that the building uses the same amount as it creates or generates – it is self-sufficient. In […]
Massimino Moretti and his WASP organization say they have developed a process that makes a 3D printed mud house out of earth.
The demand for sustainable lumber is growing. SNW in Portland, Oregon specializes in alder, maple, juniper, myrtle, walnut, and white oak, among others.
For every ton of rice that is grown, 500 lbs of rice husks and straw are created. Typically, those husks and straw are burned as waste. But two innovations on opposite sides of the world are changing that. In India, 16-year-old Bisman Deu saw all those rice husks being burned and wondered whether they couldn’t be […]
